+Alternative Boot Flows
+======================
+
+EL3 payloads alternative boot flow
+----------------------------------
+
+On a pre-production system, the ability to execute arbitrary, bare-metal code at
+the highest exception level is required. It allows full, direct access to the
+hardware, for example to run silicon soak tests.
+
+Although it is possible to implement some baremetal secure firmware from
+scratch, this is a complex task on some platforms, depending on the level of
+configuration required to put the system in the expected state.
+
+Rather than booting a baremetal application, a possible compromise is to boot
+``EL3 payloads`` through TF-A instead. This is implemented as an alternative
+boot flow, where a modified BL2 boots an EL3 payload, instead of loading the
+other BL images and passing control to BL31. It reduces the complexity of
+developing EL3 baremetal code by:
+
+-  putting the system into a known architectural state;
+-  taking care of platform secure world initialization;
+-  loading the SCP_BL2 image if required by the platform.
+
+When booting an EL3 payload on Arm standard platforms, the configuration of the
+TrustZone controller is simplified such that only region 0 is enabled and is
+configured to permit secure access only. This gives full access to the whole
+DRAM to the EL3 payload.
+
+The system is left in the same state as when entering BL31 in the default boot
+flow. In particular:
+
+-  Running in EL3;
+-  Current state is AArch64;
+-  Little-endian data access;
+-  All exceptions disabled;
+-  MMU disabled;
+-  Caches disabled.
+
+.. _alt_boot_flows_el3_payload:
+
+Booting an EL3 payload
+~~~~~~~~~~~~~~~~~~~~~~
+
+The EL3 payload image is a standalone image and is not part of the FIP. It is
+not loaded by TF-A. Therefore, there are 2 possible scenarios:
+
+-  The EL3 payload may reside in non-volatile memory (NVM) and execute in
+   place. In this case, booting it is just a matter of specifying the right
+   address in NVM through ``EL3_PAYLOAD_BASE`` when building TF-A.
+
+-  The EL3 payload needs to be loaded in volatile memory (e.g. DRAM) at
+   run-time.
+
+To help in the latter scenario, the ``SPIN_ON_BL1_EXIT=1`` build option can be
+used. The infinite loop that it introduces in BL1 stops execution at the right
+moment for a debugger to take control of the target and load the payload (for
+example, over JTAG).
+
+It is expected that this loading method will work in most cases, as a debugger
+connection is usually available in a pre-production system. The user is free to
+use any other platform-specific mechanism to load the EL3 payload, though.
+
+
+Preloaded BL33 alternative boot flow
+------------------------------------
+
+Some platforms have the ability to preload BL33 into memory instead of relying
+on TF-A to load it. This may simplify packaging of the normal world code and
+improve performance in a development environment. When secure world cold boot
+is complete, TF-A simply jumps to a BL33 base address provided at build time.
+
+For this option to be used, the ``PRELOADED_BL33_BASE`` build option has to be
+used when compiling TF-A. For example, the following command will create a FIP
+without a BL33 and prepare to jump to a BL33 image loaded at address
+0x80000000:
+
+.. code:: shell
+
+    make PRELOADED_BL33_BASE=0x80000000 PLAT=fvp all fip

+Building FIP images with support for Trusted Board Boot
+=======================================================
+
+Trusted Board Boot primarily consists of the following two features:
+
+-  Image Authentication, described in :ref:`Trusted Board Boot`, and
+-  Firmware Update, described in :ref:`Firmware Update (FWU)`
+
+The following steps should be followed to build FIP and (optionally) FWU_FIP
+images with support for these features:
+
+#. Fulfill the dependencies of the ``mbedtls`` cryptographic and image parser
+   modules by checking out a recent version of the `mbed TLS Repository`_. It
+   is important to use a version that is compatible with TF-A and fixes any
+   known security vulnerabilities. See `mbed TLS Security Center`_ for more
+   information. See the :ref:`Prerequisites` document for the appropriate
+   version of mbed TLS to use.
+
+   The ``drivers/auth/mbedtls/mbedtls_*.mk`` files contain the list of mbed TLS
+   source files the modules depend upon.
+   ``include/drivers/auth/mbedtls/mbedtls_config.h`` contains the configuration
+   options required to build the mbed TLS sources.
+
+   Note that the mbed TLS library is licensed under the Apache version 2.0
+   license. Using mbed TLS source code will affect the licensing of TF-A
+   binaries that are built using this library.
+
+#. To build the FIP image, ensure the following command line variables are set
+   while invoking ``make`` to build TF-A:
+
+   -  ``MBEDTLS_DIR=<path of the directory containing mbed TLS sources>``
+   -  ``TRUSTED_BOARD_BOOT=1``
+   -  ``GENERATE_COT=1``
+
+   In the case of Arm platforms, the location of the ROTPK hash must also be
+   specified at build time. Two locations are currently supported (see
+   ``ARM_ROTPK_LOCATION`` build option):
+
+   -  ``ARM_ROTPK_LOCATION=regs``: the ROTPK hash is obtained from the Trusted
+      root-key storage registers present in the platform. On Juno, this
+      registers are read-only. On FVP Base and Cortex models, the registers
+      are read-only, but the value can be specified using the command line
+      option ``bp.trusted_key_storage.public_key`` when launching the model.
+      On both Juno and FVP models, the default value corresponds to an
+      ECDSA-SECP256R1 public key hash, whose private part is not currently
+      available.
+
+   -  ``ARM_ROTPK_LOCATION=devel_rsa``: use the ROTPK hash that is hardcoded
+      in the Arm platform port. The private/public RSA key pair may be
+      found in ``plat/arm/board/common/rotpk``.
+
+   -  ``ARM_ROTPK_LOCATION=devel_ecdsa``: use the ROTPK hash that is hardcoded
+      in the Arm platform port. The private/public ECDSA key pair may be
+      found in ``plat/arm/board/common/rotpk``.
+
+   Example of command line using RSA development keys:
+
+   .. code:: shell
+
+       MBEDTLS_DIR=<path of the directory containing mbed TLS sources> \
+       make PLAT=<platform> TRUSTED_BOARD_BOOT=1 GENERATE_COT=1        \
+       ARM_ROTPK_LOCATION=devel_rsa                                    \
+       ROT_KEY=plat/arm/board/common/rotpk/arm_rotprivk_rsa.pem        \
+       BL33=<path-to>/<bl33_image>                                     \
+       all fip
+
+   The result of this build will be the bl1.bin and the fip.bin binaries. This
+   FIP will include the certificates corresponding to the Chain of Trust
+   described in the TBBR-client document. These certificates can also be found
+   in the output build directory.
+
+#. The optional FWU_FIP contains any additional images to be loaded from
+   Non-Volatile storage during the :ref:`Firmware Update (FWU)` process. To build the
+   FWU_FIP, any FWU images required by the platform must be specified on the
+   command line. On Arm development platforms like Juno, these are:
+
+   -  NS_BL2U. The AP non-secure Firmware Updater image.
+   -  SCP_BL2U. The SCP Firmware Update Configuration image.
+
+   Example of Juno command line for generating both ``fwu`` and ``fwu_fip``
+   targets using RSA development:
+
+   ::
+
+       MBEDTLS_DIR=<path of the directory containing mbed TLS sources> \
+       make PLAT=juno TRUSTED_BOARD_BOOT=1 GENERATE_COT=1              \
+       ARM_ROTPK_LOCATION=devel_rsa                                    \
+       ROT_KEY=plat/arm/board/common/rotpk/arm_rotprivk_rsa.pem        \
+       BL33=<path-to>/<bl33_image>                                     \
+       SCP_BL2=<path-to>/<scp_bl2_image>                               \

+       all fip fwu_fip
+
+   .. note::
+      The BL2U image will be built by default and added to the FWU_FIP.
+      The user may override this by adding ``BL2U=<path-to>/<bl2u_image>``
+      to the command line above.
+
+   .. note::
+      Building and installing the non-secure and SCP FWU images (NS_BL1U,
+      NS_BL2U and SCP_BL2U) is outside the scope of this document.
+
+   The result of this build will be bl1.bin, fip.bin and fwu_fip.bin binaries.
+   Both the FIP and FWU_FIP will include the certificates corresponding to the
+   Chain of Trust described in the TBBR-client document. These certificates
+   can also be found in the output build directory.

+Build Options
+=============
+
+The TF-A build system supports the following build options. Unless mentioned
+otherwise, these options are expected to be specified at the build command
+line and are not to be modified in any component makefiles. Note that the
+build system doesn't track dependency for build options. Therefore, if any of
+the build options are changed from a previous build, a clean build must be
+performed.
+
+.. _build_options_common:
+
+Common build options
+--------------------
+
+-  ``AARCH32_INSTRUCTION_SET``: Choose the AArch32 instruction set that the
+   compiler should use. Valid values are T32 and A32. It defaults to T32 due to
+   code having a smaller resulting size.
+
+-  ``AARCH32_SP`` : Choose the AArch32 Secure Payload component to be built as
+   as the BL32 image when ``ARCH=aarch32``. The value should be the path to the
+   directory containing the SP source, relative to the ``bl32/``; the directory
+   is expected to contain a makefile called ``<aarch32_sp-value>.mk``.
+
+-  ``ARCH`` : Choose the target build architecture for TF-A. It can take either
+   ``aarch64`` or ``aarch32`` as values. By default, it is defined to
+   ``aarch64``.
+
+-  ``ARM_ARCH_MAJOR``: The major version of Arm Architecture to target when
+   compiling TF-A. Its value must be numeric, and defaults to 8 . See also,
+   *Armv8 Architecture Extensions* and *Armv7 Architecture Extensions* in
+   :ref:`Firmware Design`.
+
+-  ``ARM_ARCH_MINOR``: The minor version of Arm Architecture to target when
+   compiling TF-A. Its value must be a numeric, and defaults to 0. See also,
+   *Armv8 Architecture Extensions* in :ref:`Firmware Design`.
+
+-  ``BL2``: This is an optional build option which specifies the path to BL2
+   image for the ``fip`` target. In this case, the BL2 in the TF-A will not be
+   built.
+
+-  ``BL2U``: This is an optional build option which specifies the path to
+   BL2U image. In this case, the BL2U in TF-A will not be built.
+
+-  ``BL2_AT_EL3``: This is an optional build option that enables the use of
+   BL2 at EL3 execution level.
+
+-  ``BL2_IN_XIP_MEM``: In some use-cases BL2 will be stored in eXecute In Place
+   (XIP) memory, like BL1. In these use-cases, it is necessary to initialize
+   the RW sections in RAM, while leaving the RO sections in place. This option
+   enable this use-case. For now, this option is only supported when BL2_AT_EL3
+   is set to '1'.
+
+-  ``BL31``: This is an optional build option which specifies the path to
+   BL31 image for the ``fip`` target. In this case, the BL31 in TF-A will not
+   be built.
+
+-  ``BL31_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
+   file that contains the BL31 private key in PEM format. If ``SAVE_KEYS=1``,
+   this file name will be used to save the key.
+
+-  ``BL32``: This is an optional build option which specifies the path to
+   BL32 image for the ``fip`` target. In this case, the BL32 in TF-A will not
+   be built.
+
+-  ``BL32_EXTRA1``: This is an optional build option which specifies the path to
+   Trusted OS Extra1 image for the  ``fip`` target.
+
+-  ``BL32_EXTRA2``: This is an optional build option which specifies the path to
+   Trusted OS Extra2 image for the ``fip`` target.
+
+-  ``BL32_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
+   file that contains the BL32 private key in PEM format. If ``SAVE_KEYS=1``,
+   this file name will be used to save the key.
+
+-  ``BL33``: Path to BL33 image in the host file system. This is mandatory for
+   ``fip`` target in case TF-A BL2 is used.
+
+-  ``BL33_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
+   file that contains the BL33 private key in PEM format. If ``SAVE_KEYS=1``,
+   this file name will be used to save the key.
+
+-  ``BRANCH_PROTECTION``: Numeric value to enable ARMv8.3 Pointer Authentication
+   and ARMv8.5 Branch Target Identification support for TF-A BL images themselves.
+   If enabled, it is needed to use a compiler that supports the option
+   ``-mbranch-protection``. Selects the branch protection features to use:
+-  0: Default value turns off all types of branch protection
+-  1: Enables all types of branch protection features
+-  2: Return address signing to its standard level
+-  3: Extend the signing to include leaf functions
+
+   The table below summarizes ``BRANCH_PROTECTION`` values, GCC compilation options
+   and resulting PAuth/BTI features.
+
+   +-------+--------------+-------+-----+
+   | Value |  GCC option  | PAuth | BTI |
+   +=======+==============+=======+=====+
+   |   0   |     none     |   N   |  N  |
+   +-------+--------------+-------+-----+
+   |   1   |   standard   |   Y   |  Y  |
+   +-------+--------------+-------+-----+
+   |   2   |   pac-ret    |   Y   |  N  |
+   +-------+--------------+-------+-----+
+   |   3   | pac-ret+leaf |   Y   |  N  |
+   +-------+--------------+-------+-----+
+
+   This option defaults to 0 and this is an experimental feature.
+   Note that Pointer Authentication is enabled for Non-secure world
+   irrespective of the value of this option if the CPU supports it.
+
+-  ``BUILD_MESSAGE_TIMESTAMP``: String used to identify the time and date of the
+   compilation of each build. It must be set to a C string (including quotes
+   where applicable). Defaults to a string that contains the time and date of
+   the compilation.
+
+-  ``BUILD_STRING``: Input string for VERSION_STRING, which allows the TF-A
+   build to be uniquely identified. Defaults to the current git commit id.
+
+-  ``CFLAGS``: Extra user options appended on the compiler's command line in
+   addition to the options set by the build system.
+
+-  ``COLD_BOOT_SINGLE_CPU``: This option indicates whether the platform may
+   release several CPUs out of reset. It can take either 0 (several CPUs may be
+   brought up) or 1 (only one CPU will ever be brought up during cold reset).
+   Default is 0. If the platform always brings up a single CPU, there is no
+   need to distinguish between primary and secondary CPUs and the boot path can
+   be optimised. The ``plat_is_my_cpu_primary()`` and
+   ``plat_secondary_cold_boot_setup()`` platform porting interfaces do not need
+   to be implemented in this case.
+
+-  ``CRASH_REPORTING``: A non-zero value enables a console dump of processor
+   register state when an unexpected exception occurs during execution of
+   BL31. This option defaults to the value of ``DEBUG`` - i.e. by default
+   this is only enabled for a debug build of the firmware.
+
+-  ``CREATE_KEYS``: This option is used when ``GENERATE_COT=1``. It tells the
+   certificate generation tool to create new keys in case no valid keys are
+   present or specified. Allowed options are '0' or '1'. Default is '1'.
+
+-  ``CTX_INCLUDE_AARCH32_REGS`` : Boolean option that, when set to 1, will cause
+   the AArch32 system registers to be included when saving and restoring the
+   CPU context. The option must be set to 0 for AArch64-only platforms (that
+   is on hardware that does not implement AArch32, or at least not at EL1 and
+   higher ELs). Default value is 1.
+
+-  ``CTX_INCLUDE_FPREGS``: Boolean option that, when set to 1, will cause the FP
+   registers to be included when saving and restoring the CPU context. Default
+   is 0.
+
+-  ``CTX_INCLUDE_PAUTH_REGS``: Boolean option that, when set to 1, enables
+   Pointer Authentication for Secure world. This will cause the ARMv8.3-PAuth
+   registers to be included when saving and restoring the CPU context as
+   part of world switch. Default value is 0 and this is an experimental feature.
+   Note that Pointer Authentication is enabled for Non-secure world irrespective
+   of the value of this flag if the CPU supports it.
+
+-  ``DEBUG``: Chooses between a debug and release build. It can take either 0
+   (release) or 1 (debug) as values. 0 is the default.
+
+-  ``DISABLE_BIN_GENERATION``: Boolean option to disable the generation
+   of the binary image. If set to 1, then only the ELF image is built.
+   0 is the default.
+
+-  ``DYN_DISABLE_AUTH``: Provides the capability to dynamically disable Trusted
+   Board Boot authentication at runtime. This option is meant to be enabled only
+   for development platforms. ``TRUSTED_BOARD_BOOT`` flag must be set if this
+   flag has to be enabled. 0 is the default.
+
+-  ``E``: Boolean option to make warnings into errors. Default is 1.
+
+-  ``EL3_PAYLOAD_BASE``: This option enables booting an EL3 payload instead of
+   the normal boot flow. It must specify the entry point address of the EL3
+   payload. Please refer to the "Booting an EL3 payload" section for more
+   details.
+
+-  ``ENABLE_AMU``: Boolean option to enable Activity Monitor Unit extensions.
+   This is an optional architectural feature available on v8.4 onwards. Some
+   v8.2 implementations also implement an AMU and this option can be used to
+   enable this feature on those systems as well. Default is 0.
+
+-  ``ENABLE_ASSERTIONS``: This option controls whether or not calls to ``assert()``
+   are compiled out. For debug builds, this option defaults to 1, and calls to
+   ``assert()`` are left in place. For release builds, this option defaults to 0
+   and calls to ``assert()`` function are compiled out. This option can be set
+   independently of ``DEBUG``. It can also be used to hide any auxiliary code
+   that is only required for the assertion and does not fit in the assertion
+   itself.
+
+-  ``ENABLE_BACKTRACE``: This option controls whether to enables backtrace
+   dumps or not. It is supported in both AArch64 and AArch32. However, in
+   AArch32 the format of the frame records are not defined in the AAPCS and they
+   are defined by the implementation. This implementation of backtrace only
+   supports the format used by GCC when T32 interworking is disabled. For this
+   reason enabling this option in AArch32 will force the compiler to only
+   generate A32 code. This option is enabled by default only in AArch64 debug
+   builds, but this behaviour can be overridden in each platform's Makefile or
+   in the build command line.
+
+ -  ``ENABLE_LTO``: Boolean option to enable Link Time Optimization (LTO)
+   support in GCC for TF-A. This option is currently only supported for
+   AArch64. Default is 0.
+
+-  ``ENABLE_MPAM_FOR_LOWER_ELS``: Boolean option to enable lower ELs to use MPAM
+   feature. MPAM is an optional Armv8.4 extension that enables various memory
+   system components and resources to define partitions; software running at
+   various ELs can assign themselves to desired partition to control their
+   performance aspects.
+
+   When this option is set to ``1``, EL3 allows lower ELs to access their own
+   MPAM registers without trapping into EL3. This option doesn't make use of
+   partitioning in EL3, however. Platform initialisation code should configure
+   and use partitions in EL3 as required. This option defaults to ``0``.
+
+-  ``ENABLE_PIE``: Boolean option to enable Position Independent Executable(PIE)
+   support within generic code in TF-A. This option is currently only supported
+   in BL31. Default is 0.
+
+-  ``ENABLE_PMF``: Boolean option to enable support for optional Performance
+   Measurement Framework(PMF). Default is 0.
+
+-  ``ENABLE_PSCI_STAT``: Boolean option to enable support for optional PSCI
+   functions ``PSCI_STAT_RESIDENCY`` and ``PSCI_STAT_COUNT``. Default is 0.
+   In the absence of an alternate stat collection backend, ``ENABLE_PMF`` must
+   be enabled. If ``ENABLE_PMF`` is set, the residency statistics are tracked in
+   software.
+
+-  ``ENABLE_RUNTIME_INSTRUMENTATION``: Boolean option to enable runtime
+   instrumentation which injects timestamp collection points into TF-A to
+   allow runtime performance to be measured. Currently, only PSCI is
+   instrumented. Enabling this option enables the ``ENABLE_PMF`` build option
+   as well. Default is 0.
+
+-  ``ENABLE_SPE_FOR_LOWER_ELS`` : Boolean option to enable Statistical Profiling
+   extensions. This is an optional architectural feature for AArch64.
+   The default is 1 but is automatically disabled when the target architecture
+   is AArch32.
+
+-  ``ENABLE_SPM`` : Boolean option to enable the Secure Partition Manager (SPM).
+   Refer to :ref:`Secure Partition Manager` for more details about
+   this feature. Default is 0.
+
+-  ``ENABLE_SVE_FOR_NS``: Boolean option to enable Scalable Vector Extension
+   (SVE) for the Non-secure world only. SVE is an optional architectural feature
+   for AArch64. Note that when SVE is enabled for the Non-secure world, access
+   to SIMD and floating-point functionality from the Secure world is disabled.
+   This is to avoid corruption of the Non-secure world data in the Z-registers
+   which are aliased by the SIMD and FP registers. The build option is not
+   compatible with the ``CTX_INCLUDE_FPREGS`` build option, and will raise an
+   assert on platforms where SVE is implemented and ``ENABLE_SVE_FOR_NS`` set to
+   1. The default is 1 but is automatically disabled when the target
+   architecture is AArch32.
+
+-  ``ENABLE_STACK_PROTECTOR``: String option to enable the stack protection
+   checks in GCC. Allowed values are "all", "strong", "default" and "none". The
+   default value is set to "none". "strong" is the recommended stack protection
+   level if this feature is desired. "none" disables the stack protection. For
+   all values other than "none", the ``plat_get_stack_protector_canary()``
+   platform hook needs to be implemented. The value is passed as the last
+   component of the option ``-fstack-protector-$ENABLE_STACK_PROTECTOR``.
+
+-  ``ERROR_DEPRECATED``: This option decides whether to treat the usage of
+   deprecated platform APIs, helper functions or drivers within Trusted
+   Firmware as error. It can take the value 1 (flag the use of deprecated
+   APIs as error) or 0. The default is 0.
+
+-  ``EL3_EXCEPTION_HANDLING``: When set to ``1``, enable handling of exceptions
+   targeted at EL3. When set ``0`` (default), no exceptions are expected or
+   handled at EL3, and a panic will result. This is supported only for AArch64
+   builds.
+
+-  ``FAULT_INJECTION_SUPPORT``: ARMv8.4 extensions introduced support for fault
+   injection from lower ELs, and this build option enables lower ELs to use
+   Error Records accessed via System Registers to inject faults. This is
+   applicable only to AArch64 builds.
+
+   This feature is intended for testing purposes only, and is advisable to keep
+   disabled for production images.
+
+-  ``FIP_NAME``: This is an optional build option which specifies the FIP
+   filename for the ``fip`` target. Default is ``fip.bin``.
+
+-  ``FWU_FIP_NAME``: This is an optional build option which specifies the FWU
+   FIP filename for the ``fwu_fip`` target. Default is ``fwu_fip.bin``.
+
+-  ``GENERATE_COT``: Boolean flag used to build and execute the ``cert_create``
+   tool to create certificates as per the Chain of Trust described in
+   :ref:`Trusted Board Boot`. The build system then calls ``fiptool`` to
+   include the certificates in the FIP and FWU_FIP. Default value is '0'.
+
+   Specify both ``TRUSTED_BOARD_BOOT=1`` and ``GENERATE_COT=1`` to include support
+   for the Trusted Board Boot feature in the BL1 and BL2 images, to generate
+   the corresponding certificates, and to include those certificates in the
+   FIP and FWU_FIP.
+
+   Note that if ``TRUSTED_BOARD_BOOT=0`` and ``GENERATE_COT=1``, the BL1 and BL2
+   images will not include support for Trusted Board Boot. The FIP will still
+   include the corresponding certificates. This FIP can be used to verify the
+   Chain of Trust on the host machine through other mechanisms.
+
+   Note that if ``TRUSTED_BOARD_BOOT=1`` and ``GENERATE_COT=0``, the BL1 and BL2
+   images will include support for Trusted Board Boot, but the FIP and FWU_FIP
+   will not include the corresponding certificates, causing a boot failure.
+
+-  ``GICV2_G0_FOR_EL3``: Unlike GICv3, the GICv2 architecture doesn't have
+   inherent support for specific EL3 type interrupts. Setting this build option
+   to ``1`` assumes GICv2 *Group 0* interrupts are expected to target EL3, both
+   by `platform abstraction layer`__ and `Interrupt Management Framework`__.
+   This allows GICv2 platforms to enable features requiring EL3 interrupt type.
+   This also means that all GICv2 Group 0 interrupts are delivered to EL3, and
+   the Secure Payload interrupts needs to be synchronously handed over to Secure
+   EL1 for handling. The default value of this option is ``0``, which means the
+   Group 0 interrupts are assumed to be handled by Secure EL1.
+
+   .. __: `platform-interrupt-controller-API.rst`
+   .. __: `interrupt-framework-design.rst`
+
+-  ``HANDLE_EA_EL3_FIRST``: When set to ``1``, External Aborts and SError
+   Interrupts will be always trapped in EL3 i.e. in BL31 at runtime. When set to
+   ``0`` (default), these exceptions will be trapped in the current exception
+   level (or in EL1 if the current exception level is EL0).
+
+-  ``HW_ASSISTED_COHERENCY``: On most Arm systems to-date, platform-specific
+   software operations are required for CPUs to enter and exit coherency.
+   However, newer systems exist where CPUs' entry to and exit from coherency
+   is managed in hardware. Such systems require software to only initiate these
+   operations, and the rest is managed in hardware, minimizing active software
+   management. In such systems, this boolean option enables TF-A to carry out
+   build and run-time optimizations during boot and power management operations.
+   This option defaults to 0 and if it is enabled, then it implies
+   ``WARMBOOT_ENABLE_DCACHE_EARLY`` is also enabled.
+
+   If this flag is disabled while the platform which TF-A is compiled for
+   includes cores that manage coherency in hardware, then a compilation error is
+   generated. This is based on the fact that a system cannot have, at the same
+   time, cores that manage coherency in hardware and cores that don't. In other
+   words, a platform cannot have, at the same time, cores that require
+   ``HW_ASSISTED_COHERENCY=1`` and cores that require
+   ``HW_ASSISTED_COHERENCY=0``.
+
+   Note that, when ``HW_ASSISTED_COHERENCY`` is enabled, version 2 of
+   translation library (xlat tables v2) must be used; version 1 of translation
+   library is not supported.
+
+-  ``JUNO_AARCH32_EL3_RUNTIME``: This build flag enables you to execute EL3
+   runtime software in AArch32 mode, which is required to run AArch32 on Juno.
+   By default this flag is set to '0'. Enabling this flag builds BL1 and BL2 in
+   AArch64 and facilitates the loading of ``SP_MIN`` and BL33 as AArch32 executable
+   images.
+
+-  ``KEY_ALG``: This build flag enables the user to select the algorithm to be
+   used for generating the PKCS keys and subsequent signing of the certificate.
+   It accepts 3 values: ``rsa``, ``rsa_1_5`` and ``ecdsa``. The option
+   ``rsa_1_5`` is the legacy PKCS#1 RSA 1.5 algorithm which is not TBBR
+   compliant and is retained only for compatibility. The default value of this
+   flag is ``rsa`` which is the TBBR compliant PKCS#1 RSA 2.1 scheme.
+
+-  ``HASH_ALG``: This build flag enables the user to select the secure hash
+   algorithm. It accepts 3 values: ``sha256``, ``sha384`` and ``sha512``.
+   The default value of this flag is ``sha256``.
+
+-  ``LDFLAGS``: Extra user options appended to the linkers' command line in
+   addition to the one set by the build system.
+
+-  ``LOG_LEVEL``: Chooses the log level, which controls the amount of console log
+   output compiled into the build. This should be one of the following:
+
+   ::
+
+       0  (LOG_LEVEL_NONE)
+       10 (LOG_LEVEL_ERROR)
+       20 (LOG_LEVEL_NOTICE)
+       30 (LOG_LEVEL_WARNING)
+       40 (LOG_LEVEL_INFO)
+       50 (LOG_LEVEL_VERBOSE)
+
+   All log output up to and including the selected log level is compiled into
+   the build. The default value is 40 in debug builds and 20 in release builds.
+
+-  ``NON_TRUSTED_WORLD_KEY``: This option is used when ``GENERATE_COT=1``. It
+   specifies the file that contains the Non-Trusted World private key in PEM
+   format. If ``SAVE_KEYS=1``, this file name will be used to save the key.
+
+-  ``NS_BL2U``: Path to NS_BL2U image in the host file system. This image is
+   optional. It is only needed if the platform makefile specifies that it
+   is required in order to build the ``fwu_fip`` target.
+
+-  ``NS_TIMER_SWITCH``: Enable save and restore for non-secure timer register
+   contents upon world switch. It can take either 0 (don't save and restore) or
+   1 (do save and restore). 0 is the default. An SPD may set this to 1 if it
+   wants the timer registers to be saved and restored.
+
+-  ``OVERRIDE_LIBC``: This option allows platforms to override the default libc
+   for the BL image. It can be either 0 (include) or 1 (remove). The default
+   value is 0.
+
+-  ``PL011_GENERIC_UART``: Boolean option to indicate the PL011 driver that
+   the underlying hardware is not a full PL011 UART but a minimally compliant
+   generic UART, which is a subset of the PL011. The driver will not access
+   any register that is not part of the SBSA generic UART specification.
+   Default value is 0 (a full PL011 compliant UART is present).
+
+-  ``PLAT``: Choose a platform to build TF-A for. The chosen platform name
+   must be subdirectory of any depth under ``plat/``, and must contain a
+   platform makefile named ``platform.mk``. For example, to build TF-A for the
+   Arm Juno board, select PLAT=juno.
+
+-  ``PRELOADED_BL33_BASE``: This option enables booting a preloaded BL33 image
+   instead of the normal boot flow. When defined, it must specify the entry
+   point address for the preloaded BL33 image. This option is incompatible with
+   ``EL3_PAYLOAD_BASE``. If both are defined, ``EL3_PAYLOAD_BASE`` has priority
+   over ``PRELOADED_BL33_BASE``.
+
+-  ``PROGRAMMABLE_RESET_ADDRESS``: This option indicates whether the reset
+   vector address can be programmed or is fixed on the platform. It can take
+   either 0 (fixed) or 1 (programmable). Default is 0. If the platform has a
+   programmable reset address, it is expected that a CPU will start executing
+   code directly at the right address, both on a cold and warm reset. In this
+   case, there is no need to identify the entrypoint on boot and the boot path
+   can be optimised. The ``plat_get_my_entrypoint()`` platform porting interface
+   does not need to be implemented in this case.
+
+-  ``PSCI_EXTENDED_STATE_ID``: As per PSCI1.0 Specification, there are 2 formats
+   possible for the PSCI power-state parameter: original and extended State-ID
+   formats. This flag if set to 1, configures the generic PSCI layer to use the
+   extended format. The default value of this flag is 0, which means by default
+   the original power-state format is used by the PSCI implementation. This flag
+   should be specified by the platform makefile and it governs the return value
+   of PSCI_FEATURES API for CPU_SUSPEND smc function id. When this option is
+   enabled on Arm platforms, the option ``ARM_RECOM_STATE_ID_ENC`` needs to be
+   set to 1 as well.
+
+-  ``RAS_EXTENSION``: When set to ``1``, enable Armv8.2 RAS features. RAS features
+   are an optional extension for pre-Armv8.2 CPUs, but are mandatory for Armv8.2
+   or later CPUs.
+
+   When ``RAS_EXTENSION`` is set to ``1``, ``HANDLE_EA_EL3_FIRST`` must also be
+   set to ``1``.
+
+   This option is disabled by default.
+
+-  ``RESET_TO_BL31``: Enable BL31 entrypoint as the CPU reset vector instead
+   of the BL1 entrypoint. It can take the value 0 (CPU reset to BL1
+   entrypoint) or 1 (CPU reset to BL31 entrypoint).
+   The default value is 0.
+
+-  ``RESET_TO_SP_MIN``: SP_MIN is the minimal AArch32 Secure Payload provided
+   in TF-A. This flag configures SP_MIN entrypoint as the CPU reset vector
+   instead of the BL1 entrypoint. It can take the value 0 (CPU reset to BL1
+   entrypoint) or 1 (CPU reset to SP_MIN entrypoint). The default value is 0.
+
+-  ``ROT_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
+   file that contains the ROT private key in PEM format. If ``SAVE_KEYS=1``, this
+   file name will be used to save the key.
+
+-  ``SAVE_KEYS``: This option is used when ``GENERATE_COT=1``. It tells the
+   certificate generation tool to save the keys used to establish the Chain of
+   Trust. Allowed options are '0' or '1'. Default is '0' (do not save).
+
+-  ``SCP_BL2``: Path to SCP_BL2 image in the host file system. This image is optional.
+   If a SCP_BL2 image is present then this option must be passed for the ``fip``
+   target.
+
+-  ``SCP_BL2_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
+   file that contains the SCP_BL2 private key in PEM format. If ``SAVE_KEYS=1``,
+   this file name will be used to save the key.
+
+-  ``SCP_BL2U``: Path to SCP_BL2U image in the host file system. This image is
+   optional. It is only needed if the platform makefile specifies that it
+   is required in order to build the ``fwu_fip`` target.
+
+-  ``SDEI_SUPPORT``: Setting this to ``1`` enables support for Software
+   Delegated Exception Interface to BL31 image. This defaults to ``0``.
+
+   When set to ``1``, the build option ``EL3_EXCEPTION_HANDLING`` must also be
+   set to ``1``.
+
+-  ``SEPARATE_CODE_AND_RODATA``: Whether code and read-only data should be
+   isolated on separate memory pages. This is a trade-off between security and
+   memory usage. See "Isolating code and read-only data on separate memory
+   pages" section in :ref:`Firmware Design`. This flag is disabled by default and
+   affects all BL images.
+
+-  ``SPD``: Choose a Secure Payload Dispatcher component to be built into TF-A.
+   This build option is only valid if ``ARCH=aarch64``. The value should be
+   the path to the directory containing the SPD source, relative to
+   ``services/spd/``; the directory is expected to contain a makefile called
+   ``<spd-value>.mk``.
+
+-  ``SPIN_ON_BL1_EXIT``: This option introduces an infinite loop in BL1. It can
+   take either 0 (no loop) or 1 (add a loop). 0 is the default. This loop stops
+   execution in BL1 just before handing over to BL31. At this point, all
+   firmware images have been loaded in memory, and the MMU and caches are
+   turned off. Refer to the "Debugging options" section for more details.
+
+-  ``SP_MIN_WITH_SECURE_FIQ``: Boolean flag to indicate the SP_MIN handles
+   secure interrupts (caught through the FIQ line). Platforms can enable
+   this directive if they need to handle such interruption. When enabled,
+   the FIQ are handled in monitor mode and non secure world is not allowed
+   to mask these events. Platforms that enable FIQ handling in SP_MIN shall
+   implement the api ``sp_min_plat_fiq_handler()``. The default value is 0.
+
+-  ``TRUSTED_BOARD_BOOT``: Boolean flag to include support for the Trusted Board
+   Boot feature. When set to '1', BL1 and BL2 images include support to load
+   and verify the certificates and images in a FIP, and BL1 includes support
+   for the Firmware Update. The default value is '0'. Generation and inclusion
+   of certificates in the FIP and FWU_FIP depends upon the value of the
+   ``GENERATE_COT`` option.
+
+   .. warning::
+      This option depends on ``CREATE_KEYS`` to be enabled. If the keys
+      already exist in disk, they will be overwritten without further notice.
+
+-  ``TRUSTED_WORLD_KEY``: This option is used when ``GENERATE_COT=1``. It
+   specifies the file that contains the Trusted World private key in PEM
+   format. If ``SAVE_KEYS=1``, this file name will be used to save the key.
+
+-  ``TSP_INIT_ASYNC``: Choose BL32 initialization method as asynchronous or
+   synchronous, (see "Initializing a BL32 Image" section in
+   :ref:`Firmware Design`). It can take the value 0 (BL32 is initialized using
+   synchronous method) or 1 (BL32 is initialized using asynchronous method).
+   Default is 0.
+
+-  ``TSP_NS_INTR_ASYNC_PREEMPT``: A non zero value enables the interrupt
+   routing model which routes non-secure interrupts asynchronously from TSP
+   to EL3 causing immediate preemption of TSP. The EL3 is responsible
+   for saving and restoring the TSP context in this routing model. The
+   default routing model (when the value is 0) is to route non-secure
+   interrupts to TSP allowing it to save its context and hand over
+   synchronously to EL3 via an SMC.
+
+   .. note::
+      When ``EL3_EXCEPTION_HANDLING`` is ``1``, ``TSP_NS_INTR_ASYNC_PREEMPT``
+      must also be set to ``1``.
+
+-  ``USE_ARM_LINK``: This flag determines whether to enable support for ARM
+   linker. When the ``LINKER`` build variable points to the armlink linker,
+   this flag is enabled automatically. To enable support for armlink, platforms
+   will have to provide a scatter file for the BL image. Currently, Tegra
+   platforms use the armlink support to compile BL3-1 images.
+
+-  ``USE_COHERENT_MEM``: This flag determines whether to include the coherent
+   memory region in the BL memory map or not (see "Use of Coherent memory in
+   TF-A" section in :ref:`Firmware Design`). It can take the value 1
+   (Coherent memory region is included) or 0 (Coherent memory region is
+   excluded). Default is 1.
+
+-  ``USE_ROMLIB``: This flag determines whether library at ROM will be used.
+   This feature creates a library of functions to be placed in ROM and thus
+   reduces SRAM usage. Refer to :ref:`Library at ROM` for further details. Default
+   is 0.
+
+-  ``V``: Verbose build. If assigned anything other than 0, the build commands
+   are printed. Default is 0.
+
+-  ``VERSION_STRING``: String used in the log output for each TF-A image.
+   Defaults to a string formed by concatenating the version number, build type
+   and build string.
+
+-  ``W``: Warning level. Some compiler warning options of interest have been
+   regrouped and put in the root Makefile. This flag can take the values 0 to 3,
+   each level enabling more warning options. Default is 0.
+
+-  ``WARMBOOT_ENABLE_DCACHE_EARLY`` : Boolean option to enable D-cache early on
+   the CPU after warm boot. This is applicable for platforms which do not
+   require interconnect programming to enable cache coherency (eg: single
+   cluster platforms). If this option is enabled, then warm boot path
+   enables D-caches immediately after enabling MMU. This option defaults to 0.
+
+Debugging options
+-----------------
+
+To compile a debug version and make the build more verbose use
+
+.. code:: shell
+
+    make PLAT=<platform> DEBUG=1 V=1 all
+
+AArch64 GCC uses DWARF version 4 debugging symbols by default. Some tools (for
+example DS-5) might not support this and may need an older version of DWARF
+symbols to be emitted by GCC. This can be achieved by using the
+``-gdwarf-<version>`` flag, with the version being set to 2 or 3. Setting the
+version to 2 is recommended for DS-5 versions older than 5.16.
+
+When debugging logic problems it might also be useful to disable all compiler
+optimizations by using ``-O0``.
+
+.. warning::
+   Using ``-O0`` could cause output images to be larger and base addresses
+   might need to be recalculated (see the **Memory layout on Arm development
+   platforms** section in the :ref:`Firmware Design`).
+
+Extra debug options can be passed to the build system by setting ``CFLAGS`` or
+``LDFLAGS``:
+
+.. code:: shell
+
+    CFLAGS='-O0 -gdwarf-2'                                     \
+    make PLAT=<platform> DEBUG=1 V=1 all
+
+Note that using ``-Wl,`` style compilation driver options in ``CFLAGS`` will be
+ignored as the linker is called directly.
+
+It is also possible to introduce an infinite loop to help in debugging the
+post-BL2 phase of TF-A. This can be done by rebuilding BL1 with the
+``SPIN_ON_BL1_EXIT=1`` build flag. Refer to the :ref:`build_options_common`
+section. In this case, the developer may take control of the target using a
+debugger when indicated by the console output. When using DS-5, the following
+commands can be used:
+
+::
+
+    # Stop target execution
+    interrupt
+
+    #
+    # Prepare your debugging environment, e.g. set breakpoints
+    #
+
+    # Jump over the debug loop
+    set var $AARCH64::$Core::$PC = $AARCH64::$Core::$PC + 4
+
+    # Resume execution
+    continue

+Performing an Initial Build
+===========================
+
+-  Before building TF-A, the environment variable ``CROSS_COMPILE`` must point
+   to the Linaro cross compiler.
+
+   For AArch64:
+
+   .. code:: shell
+
+       export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-linux-gnu-
+
+   For AArch32:
+
+   .. code:: shell
+
+       export CROSS_COMPILE=<path-to-aarch32-gcc>/bin/arm-eabi-
+
+   It is possible to build TF-A using Clang or Arm Compiler 6. To do so
+   ``CC`` needs to point to the clang or armclang binary, which will
+   also select the clang or armclang assembler. Be aware that the
+   GNU linker is used by default.  In case of being needed the linker
+   can be overridden using the ``LD`` variable. Clang linker version 6 is
+   known to work with TF-A.
+
+   In both cases ``CROSS_COMPILE`` should be set as described above.
+
+   Arm Compiler 6 will be selected when the base name of the path assigned
+   to ``CC`` matches the string 'armclang'.
+
+   For AArch64 using Arm Compiler 6:
+
+   .. code:: shell
+
+       export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-linux-gnu-
+       make CC=<path-to-armclang>/bin/armclang PLAT=<platform> all
+
+   Clang will be selected when the base name of the path assigned to ``CC``
+   contains the string 'clang'. This is to allow both clang and clang-X.Y
+   to work.
+
+   For AArch64 using clang:
+
+   .. code:: shell
+
+       export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-linux-gnu-
+       make CC=<path-to-clang>/bin/clang PLAT=<platform> all
+
+-  Change to the root directory of the TF-A source tree and build.
+
+   For AArch64:
+
+   .. code:: shell
+
+       make PLAT=<platform> all
+
+   For AArch32:
+
+   .. code:: shell
+
+       make PLAT=<platform> ARCH=aarch32 AARCH32_SP=sp_min all
+
+   Notes:
+
+   -  If ``PLAT`` is not specified, ``fvp`` is assumed by default. See the
+      :ref:`Build Options` document for more information on available build
+      options.
+
+   -  (AArch32 only) Currently only ``PLAT=fvp`` is supported.
+
+   -  (AArch32 only) ``AARCH32_SP`` is the AArch32 EL3 Runtime Software and it
+      corresponds to the BL32 image. A minimal ``AARCH32_SP``, sp_min, is
+      provided by TF-A to demonstrate how PSCI Library can be integrated with
+      an AArch32 EL3 Runtime Software. Some AArch32 EL3 Runtime Software may
+      include other runtime services, for example Trusted OS services. A guide
+      to integrate PSCI library with AArch32 EL3 Runtime Software can be found
+      at :ref:`PSCI Library Integration guide for Armv8-A AArch32 systems`.
+
+   -  (AArch64 only) The TSP (Test Secure Payload), corresponding to the BL32
+      image, is not compiled in by default. Refer to the
+      :ref:`Test Secure Payload (TSP) and Dispatcher (TSPD)` document for
+      details on building the TSP.
+
+   -  By default this produces a release version of the build. To produce a
+      debug version instead, refer to the "Debugging options" section below.
+
+   -  The build process creates products in a ``build`` directory tree, building
+      the objects and binaries for each boot loader stage in separate
+      sub-directories. The following boot loader binary files are created
+      from the corresponding ELF files:
+
+      -  ``build/<platform>/<build-type>/bl1.bin``
+      -  ``build/<platform>/<build-type>/bl2.bin``
+      -  ``build/<platform>/<build-type>/bl31.bin`` (AArch64 only)
+      -  ``build/<platform>/<build-type>/bl32.bin`` (mandatory for AArch32)
+
+      where ``<platform>`` is the name of the chosen platform and ``<build-type>``
+      is either ``debug`` or ``release``. The actual number of images might differ
+      depending on the platform.
+
+-  Build products for a specific build variant can be removed using:
+
+   .. code:: shell
+
+       make DEBUG=<D> PLAT=<platform> clean
+
+   ... where ``<D>`` is ``0`` or ``1``, as specified when building.
+
+   The build tree can be removed completely using:
+
+   .. code:: shell
+
+       make realclean

+Prerequisites
+=============
+
+This document describes the software requirements for building |TF-A| for
+AArch32 and AArch64 target platforms.
+
+It may possible to build |TF-A| with combinations of software packages that are
+different from those listed below, however only the software described in this
+document can be officially supported.
+
+Build Host
+----------
+
+|TF-A| can be built using either a Linux or a Windows machine as the build host.
+
+A relatively recent Linux distribution is recommended for building |TF-A|. We
+have performed tests using Ubuntu 16.04 LTS (64-bit) but other distributions
+should also work fine as a base, provided that the necessary tools and libraries
+can be installed.
+
+.. _prerequisites_toolchain:
+
+Toolchain
+---------
+
+|TF-A| can be built with any of the following *cross-compiler* toolchains that
+target the Armv7-A or Armv8-A architectures:
+
+- GCC >= 8.3-2019.03 (from the `Arm Developer website`_)
+- Clang >= 4.0
+- Arm Compiler >= 6.0
+
+In addition, a native compiler is required to build the supporting tools.
+
+.. note::
+   The software has also been built on Windows 7 Enterprise SP1, using CMD.EXE,
+   Cygwin, and Msys (MinGW) shells, using version 5.3.1 of the GNU toolchain.
+
+.. note::
+   For instructions on how to select the cross compiler refer to
+   :ref:`Performing an Initial Build`.
+
+.. _prerequisites_software_and_libraries:
+
+Software and Libraries
+----------------------
+
+The following tools are required to obtain and build |TF-A|:
+
+- An appropriate toolchain (see :ref:`prerequisites_toolchain`)
+- GNU Make
+- Git
+
+The following libraries must be available to build one or more components or
+supporting tools:
+
+- OpenSSL >= 1.0.1
+
+   Required to build the cert_create tool.
+
+The following libraries are required for Trusted Board Boot support:
+
+- mbed TLS == 2.16.2 (tag: ``mbedtls-2.16.2``)
+
+These tools are optional:
+
+- Device Tree Compiler (DTC) >= 1.4.6
+
+   Needed if you want to rebuild the provided Flattened Device Tree (FDT)
+   source files (``.dts`` files). DTC is available for Linux through the package
+   repositories of most distributions.
+
+- Arm `Development Studio 5 (DS-5)`_
+
+   The standard software package used for debugging software on Arm development
+   platforms and |FVP| models.
+
+Package Installation (Linux)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you are using the recommended Ubuntu distribution then you can install the
+required packages with the following command:
+
+.. code:: shell
+
+    sudo apt install build-essential git libssl-dev
+
+The optional packages can be installed using:
+
+.. code:: shell
+
+    sudo apt install device-tree-compiler
+
+Supporting Files
+----------------
+
+TF-A has been tested with pre-built binaries and file systems from `Linaro
+Release 19.06`_. Alternatively, you can build the binaries from source using
+instructions in :ref:`Performing an Initial Build`.
+
+.. _prerequisites_get_source:
+
+Getting the TF-A Source
+-----------------------
+
+Source code for |TF-A| is maintained in a Git repository hosted on
+TrustedFirmware.org. To clone this repository from the server, run the following
+in your shell:
+
+.. code:: shell
+
+    git clone "https://review.trustedfirmware.org/TF-A/trusted-firmware-a" && (cd "trusted-firmware-a" && mkdir -p .git/hooks && curl -Lo `git rev-parse --git-dir`/hooks/commit-msg https://review.trustedfirmware.org/tools/hooks/commit-msg; chmod +x `git rev-parse --git-dir`/hooks/commit-msg)
+
+This will clone the Git repository also install a *commit hook* that
+automatically inserts appropriate *Change-Id:* lines at the end of your
+commit messages. These change IDs are required when committing changes that you
+intend to push for review via our Gerrit system.
+
+You can read more about Git hooks in the *githooks* page of the Git documentation,
+available at: https://git-scm.com/docs/githooks
+
+Alternatively, you can clone without the commit hook using:
+
+.. code:: shell
+
+    git clone "https://review.trustedfirmware.org/TF-A/trusted-firmware-a"

+Building Supporting Tools
+=========================
+
+Building and using the FIP tool
+-------------------------------
+
+Firmware Image Package (FIP) is a packaging format used by TF-A to package
+firmware images in a single binary. The number and type of images that should
+be packed in a FIP is platform specific and may include TF-A images and other
+firmware images required by the platform. For example, most platforms require
+a BL33 image which corresponds to the normal world bootloader (e.g. UEFI or
+U-Boot).
+
+The TF-A build system provides the make target ``fip`` to create a FIP file
+for the specified platform using the FIP creation tool included in the TF-A
+project. Examples below show how to build a FIP file for FVP, packaging TF-A
+and BL33 images.
+
+For AArch64:
+
+.. code:: shell
+
+    make PLAT=fvp BL33=<path-to>/bl33.bin fip
+
+For AArch32:
+
+.. code:: shell
+
+    make PLAT=fvp ARCH=aarch32 AARCH32_SP=sp_min BL33=<path-to>/bl33.bin fip
+
+The resulting FIP may be found in:
+
+::
+
+    build/fvp/<build-type>/fip.bin
+
+For advanced operations on FIP files, it is also possible to independently build
+the tool and create or modify FIPs using this tool. To do this, follow these
+steps:
+
+It is recommended to remove old artifacts before building the tool:
+
+.. code:: shell
+
+    make -C tools/fiptool clean
+
+Build the tool:
+
+.. code:: shell
+
+    make [DEBUG=1] [V=1] fiptool
+
+The tool binary can be located in:
+
+::
+
+    ./tools/fiptool/fiptool
+
+Invoking the tool with ``help`` will print a help message with all available
+options.
+
+Example 1: create a new Firmware package ``fip.bin`` that contains BL2 and BL31:
+
+.. code:: shell
+
+    ./tools/fiptool/fiptool create \
+        --tb-fw build/<platform>/<build-type>/bl2.bin \
+        --soc-fw build/<platform>/<build-type>/bl31.bin \
+        fip.bin
+
+Example 2: view the contents of an existing Firmware package:
+
+.. code:: shell
+
+    ./tools/fiptool/fiptool info <path-to>/fip.bin
+
+Example 3: update the entries of an existing Firmware package:
+
+.. code:: shell
+
+    # Change the BL2 from Debug to Release version
+    ./tools/fiptool/fiptool update \
+        --tb-fw build/<platform>/release/bl2.bin \
+        build/<platform>/debug/fip.bin
+
+Example 4: unpack all entries from an existing Firmware package:
+
+.. code:: shell
+
+    # Images will be unpacked to the working directory
+    ./tools/fiptool/fiptool unpack <path-to>/fip.bin
+
+Example 5: remove an entry from an existing Firmware package:
+
+.. code:: shell
+
+    ./tools/fiptool/fiptool remove \
+        --tb-fw build/<platform>/debug/fip.bin
+
+Note that if the destination FIP file exists, the create, update and
+remove operations will automatically overwrite it.
+
+The unpack operation will fail if the images already exist at the

+
+Building the Certificate Generation Tool
+----------------------------------------
+
+The ``cert_create`` tool is built as part of the TF-A build process when the
+``fip`` make target is specified and TBB is enabled (as described in the
+previous section), but it can also be built separately with the following
+command:
+
+.. code:: shell
+
+    make PLAT=<platform> [DEBUG=1] [V=1] certtool
+
+For platforms that require their own IDs in certificate files, the generic
+'cert_create' tool can be built with the following command. Note that the target
+platform must define its IDs within a ``platform_oid.h`` header file for the
+build to succeed.
+
+.. code:: shell
+
+    make PLAT=<platform> USE_TBBR_DEFS=0 [DEBUG=1] [V=1] certtool
+
+``DEBUG=1`` builds the tool in debug mode. ``V=1`` makes the build process more
+verbose. The following command should be used to obtain help about the tool:
+
+.. code:: shell
+
+    ./tools/cert_create/cert_create -h

-User Guide
-==========
-
-This document describes how to build Trusted Firmware-A (TF-A) and run it with a
-tested set of other software components using defined configurations on the Juno
-Arm development platform and Arm Fixed Virtual Platform (FVP) models. It is
-possible to use other software components, configurations and platforms but that
-is outside the scope of this document.
-
-This document assumes that the reader has previous experience running a fully
-bootable Linux software stack on Juno or FVP using the prebuilt binaries and
-filesystems provided by Linaro. Further information may be found in the
-`Linaro instructions`_. It also assumes that the user understands the role of
-the different software components required to boot a Linux system:
-
--  Specific firmware images required by the platform (e.g. SCP firmware on Juno)
--  Normal world bootloader (e.g. UEFI or U-Boot)
--  Device tree
--  Linux kernel image
--  Root filesystem
-
-This document also assumes that the user is familiar with the `FVP models`_ and
-the different command line options available to launch the model.
-
-This document should be used in conjunction with the :ref:`Firmware Design`.
-
-Host machine requirements
--------------------------
-
-The minimum recommended machine specification for building the software and
-running the FVP models is a dual-core processor running at 2GHz with 12GB of
-RAM. For best performance, use a machine with a quad-core processor running at
-2.6GHz with 16GB of RAM.
-
-The software has been tested on Ubuntu 16.04 LTS (64-bit). Packages used for
-building the software were installed from that distribution unless otherwise
-specified.
-
-The software has also been built on Windows 7 Enterprise SP1, using CMD.EXE,
-Cygwin, and Msys (MinGW) shells, using version 5.3.1 of the GNU toolchain.
-
-Tools
------
-
-Install the required packages to build TF-A with the following command:
-
-.. code:: shell
-
-    sudo apt-get install device-tree-compiler build-essential gcc make git libssl-dev
-
-Download and install the AArch32 (arm-eabi) or AArch64 little-endian
-(aarch64-linux-gnu) GCC 8.3-2019.03 cross compiler from `Arm Developer page`_.
-
-Optionally, TF-A can be built using clang version 4.0 or newer or Arm
-Compiler 6. See instructions below on how to switch the default compiler.
-
-In addition, the following optional packages and tools may be needed:
-
--  ``device-tree-compiler`` (dtc) package if you need to rebuild the Flattened Device
-   Tree (FDT) source files (``.dts`` files) provided with this software. The
-   version of dtc must be 1.4.6 or above.
-
--  For debugging, Arm `Development Studio 5 (DS-5)`_.
-
--  To create and modify the diagram files included in the documentation, `Dia`_.
-   This tool can be found in most Linux distributions. Inkscape is needed to
-   generate the actual \*.png files.
-
-TF-A has been tested with pre-built binaries and file systems from
-`Linaro Release 19.06`_. Alternatively, you can build the binaries from
-source using instructions provided at the `Arm Platforms User guide`_.
-
-Getting the TF-A source code
-----------------------------
-
-Clone the repository from the Gerrit server. The project details may be found
-on the `arm-trusted-firmware-a project page`_. We recommend the "`Clone with
-commit-msg hook`" clone method, which will setup the git commit hook that
-automatically generates and inserts appropriate `Change-Id:` lines in your
-commit messages.
-
-Checking source code style
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Trusted Firmware follows the `Linux Coding Style`_ . When making changes to the
-source, for submission to the project, the source must be in compliance with
-this style guide.
-
-Additional, project-specific guidelines are defined in the
-:ref:`Coding Style & Guidelines` document.
-
-To assist with coding style compliance, the project Makefile contains two
-targets which both utilise the `checkpatch.pl` script that ships with the Linux
-source tree. The project also defines certain *checkpatch* options in the
-``.checkpatch.conf`` file in the top-level directory.
-
-.. note::
-   Checkpatch errors will gate upstream merging of pull requests.
-   Checkpatch warnings will not gate merging but should be reviewed and fixed if
-   possible.
-
-To check the entire source tree, you must first download copies of
-``checkpatch.pl``, ``spelling.txt`` and ``const_structs.checkpatch`` available
-in the `Linux master tree`_ *scripts* directory, then set the ``CHECKPATCH``
-environment variable to point to ``checkpatch.pl`` (with the other 2 files in
-the same directory) and build the `checkcodebase` target:
-
-.. code:: shell
-
-    make CHECKPATCH=<path-to-linux>/linux/scripts/checkpatch.pl checkcodebase
-
-To just check the style on the files that differ between your local branch and
-the remote master, use:
-
-.. code:: shell
-
-    make CHECKPATCH=<path-to-linux>/linux/scripts/checkpatch.pl checkpatch
-
-If you wish to check your patch against something other than the remote master,
-set the ``BASE_COMMIT`` variable to your desired branch. By default, ``BASE_COMMIT``
-is set to ``origin/master``.
-
-Building TF-A
--------------
-
--  Before building TF-A, the environment variable ``CROSS_COMPILE`` must point
-   to the cross compiler.
-
-   For AArch64:
-
-   .. code:: shell
-
-       export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-linux-gnu-
-
-   For AArch32:
-
-   .. code:: shell
-
-       export CROSS_COMPILE=<path-to-aarch32-gcc>/bin/arm-eabi-
-
-   It is possible to build TF-A using Clang or Arm Compiler 6. To do so
-   ``CC`` needs to point to the clang or armclang binary, which will
-   also select the clang or armclang assembler. Be aware that the
-   GNU linker is used by default.  In case of being needed the linker
-   can be overridden using the ``LD`` variable. Clang linker version 6 is
-   known to work with TF-A.
-
-   In both cases ``CROSS_COMPILE`` should be set as described above.
-
-   Arm Compiler 6 will be selected when the base name of the path assigned
-   to ``CC`` matches the string 'armclang'.
-
-   For AArch64 using Arm Compiler 6:
-
-   .. code:: shell
-
-       export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-linux-gnu-
-       make CC=<path-to-armclang>/bin/armclang PLAT=<platform> all
-
-   Clang will be selected when the base name of the path assigned to ``CC``
-   contains the string 'clang'. This is to allow both clang and clang-X.Y
-   to work.
-
-   For AArch64 using clang:
-
-   .. code:: shell
-
-       export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-linux-gnu-
-       make CC=<path-to-clang>/bin/clang PLAT=<platform> all
-
--  Change to the root directory of the TF-A source tree and build.
-
-   For AArch64:
-
-   .. code:: shell
-
-       make PLAT=<platform> all
-
-   For AArch32:
-
-   .. code:: shell
-
-       make PLAT=<platform> ARCH=aarch32 AARCH32_SP=sp_min all
-
-   Notes:
-
-   -  If ``PLAT`` is not specified, ``fvp`` is assumed by default. See the
-      `Summary of build options`_ for more information on available build
-      options.
-
-   -  (AArch32 only) ``AARCH32_SP`` is the AArch32 EL3 Runtime Software and it
-      corresponds to the BL32 image. A minimal ``AARCH32_SP``, sp_min, is
-      provided by TF-A to demonstrate how PSCI Library can be integrated with
-      an AArch32 EL3 Runtime Software. Some AArch32 EL3 Runtime Software may
-      include other runtime services, for example Trusted OS services. A guide
-      to integrate PSCI library with AArch32 EL3 Runtime Software can be found
-      at :ref:`PSCI Library Integration guide for Armv8-A AArch32 systems`.
-
-   -  (AArch64 only) The TSP (Test Secure Payload), corresponding to the BL32
-      image, is not compiled in by default. Refer to the
-      `Building the Test Secure Payload`_ section below.
-
-   -  By default this produces a release version of the build. To produce a
-      debug version instead, refer to the "Debugging options" section below.
-
-   -  The build process creates products in a ``build`` directory tree, building
-      the objects and binaries for each boot loader stage in separate
-      sub-directories. The following boot loader binary files are created
-      from the corresponding ELF files:
-
-      -  ``build/<platform>/<build-type>/bl1.bin``
-      -  ``build/<platform>/<build-type>/bl2.bin``
-      -  ``build/<platform>/<build-type>/bl31.bin`` (AArch64 only)
-      -  ``build/<platform>/<build-type>/bl32.bin`` (mandatory for AArch32)
-
-      where ``<platform>`` is the name of the chosen platform and ``<build-type>``
-      is either ``debug`` or ``release``. The actual number of images might differ
-      depending on the platform.
-
--  Build products for a specific build variant can be removed using:
-
-   .. code:: shell
-
-       make DEBUG=<D> PLAT=<platform> clean
-
-   ... where ``<D>`` is ``0`` or ``1``, as specified when building.
-
-   The build tree can be removed completely using:
-
-   .. code:: shell
-
-       make realclean
-
-Summary of build options
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-The TF-A build system supports the following build options. Unless mentioned
-otherwise, these options are expected to be specified at the build command
-line and are not to be modified in any component makefiles. Note that the
-build system doesn't track dependency for build options. Therefore, if any of
-the build options are changed from a previous build, a clean build must be
-performed.
-
-Common build options
-^^^^^^^^^^^^^^^^^^^^
-
--  ``AARCH32_INSTRUCTION_SET``: Choose the AArch32 instruction set that the
-   compiler should use. Valid values are T32 and A32. It defaults to T32 due to
-   code having a smaller resulting size.
-
--  ``AARCH32_SP`` : Choose the AArch32 Secure Payload component to be built as
-   as the BL32 image when ``ARCH=aarch32``. The value should be the path to the
-   directory containing the SP source, relative to the ``bl32/``; the directory
-   is expected to contain a makefile called ``<aarch32_sp-value>.mk``.
-
--  ``ARCH`` : Choose the target build architecture for TF-A. It can take either
-   ``aarch64`` or ``aarch32`` as values. By default, it is defined to
-   ``aarch64``.
-
--  ``ARM_ARCH_MAJOR``: The major version of Arm Architecture to target when
-   compiling TF-A. Its value must be numeric, and defaults to 8 . See also,
-   *Armv8 Architecture Extensions* and *Armv7 Architecture Extensions* in
-   :ref:`Firmware Design`.
-
--  ``ARM_ARCH_MINOR``: The minor version of Arm Architecture to target when
-   compiling TF-A. Its value must be a numeric, and defaults to 0. See also,
-   *Armv8 Architecture Extensions* in :ref:`Firmware Design`.
-
--  ``BL2``: This is an optional build option which specifies the path to BL2
-   image for the ``fip`` target. In this case, the BL2 in the TF-A will not be
-   built.
-
--  ``BL2U``: This is an optional build option which specifies the path to
-   BL2U image. In this case, the BL2U in TF-A will not be built.
-
--  ``BL2_AT_EL3``: This is an optional build option that enables the use of
-   BL2 at EL3 execution level.
-
--  ``BL2_IN_XIP_MEM``: In some use-cases BL2 will be stored in eXecute In Place
-   (XIP) memory, like BL1. In these use-cases, it is necessary to initialize
-   the RW sections in RAM, while leaving the RO sections in place. This option
-   enable this use-case. For now, this option is only supported when BL2_AT_EL3
-   is set to '1'.
-
--  ``BL2_INV_DCACHE``: This is an optional build option which control dcache
-   invalidation upon BL2 entry. Some platform cannot handle cache operations
-   during entry as the coherency unit is not yet initialized. This may cause
-   crashing. Leaving this option to '1' (default) will allow the operation.
-   This option is only relevant when BL2_AT_EL3 is set to '1'.
-
--  ``BL31``: This is an optional build option which specifies the path to
-   BL31 image for the ``fip`` target. In this case, the BL31 in TF-A will not
-   be built.
-
--  ``BL31_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
-   file that contains the BL31 private key in PEM format. If ``SAVE_KEYS=1``,
-   this file name will be used to save the key.
-
--  ``BL32``: This is an optional build option which specifies the path to
-   BL32 image for the ``fip`` target. In this case, the BL32 in TF-A will not
-   be built.
-
--  ``BL32_EXTRA1``: This is an optional build option which specifies the path to
-   Trusted OS Extra1 image for the  ``fip`` target.
-
--  ``BL32_EXTRA2``: This is an optional build option which specifies the path to
-   Trusted OS Extra2 image for the ``fip`` target.
-
--  ``BL32_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
-   file that contains the BL32 private key in PEM format. If ``SAVE_KEYS=1``,
-   this file name will be used to save the key.
-
--  ``BL33``: Path to BL33 image in the host file system. This is mandatory for
-   ``fip`` target in case TF-A BL2 is used.
-
--  ``BL33_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
-   file that contains the BL33 private key in PEM format. If ``SAVE_KEYS=1``,
-   this file name will be used to save the key.
-
--  ``BRANCH_PROTECTION``: Numeric value to enable ARMv8.3 Pointer Authentication
-   and ARMv8.5 Branch Target Identification support for TF-A BL images themselves.
-   If enabled, it is needed to use a compiler (e.g GCC 9.1 and later versions) that
-   supports the option ``-mbranch-protection``.
-   Selects the branch protection features to use:
--  0: Default value turns off all types of branch protection
--  1: Enables all types of branch protection features
--  2: Return address signing to its standard level
--  3: Extend the signing to include leaf functions
-
-   The table below summarizes ``BRANCH_PROTECTION`` values, GCC compilation options
-   and resulting PAuth/BTI features.
-
-   +-------+--------------+-------+-----+
-   | Value |  GCC option  | PAuth | BTI |
-   +=======+==============+=======+=====+
-   |   0   |     none     |   N   |  N  |
-   +-------+--------------+-------+-----+
-   |   1   |   standard   |   Y   |  Y  |
-   +-------+--------------+-------+-----+
-   |   2   |   pac-ret    |   Y   |  N  |
-   +-------+--------------+-------+-----+
-   |   3   | pac-ret+leaf |   Y   |  N  |
-   +-------+--------------+-------+-----+
-
-   This option defaults to 0 and this is an experimental feature.
-   Note that Pointer Authentication is enabled for Non-secure world
-   irrespective of the value of this option if the CPU supports it.
-
--  ``BUILD_MESSAGE_TIMESTAMP``: String used to identify the time and date of the
-   compilation of each build. It must be set to a C string (including quotes
-   where applicable). Defaults to a string that contains the time and date of
-   the compilation.
-
--  ``BUILD_STRING``: Input string for VERSION_STRING, which allows the TF-A
-   build to be uniquely identified. Defaults to the current git commit id.
-
--  ``CFLAGS``: Extra user options appended on the compiler's command line in
-   addition to the options set by the build system.
-
--  ``COLD_BOOT_SINGLE_CPU``: This option indicates whether the platform may
-   release several CPUs out of reset. It can take either 0 (several CPUs may be
-   brought up) or 1 (only one CPU will ever be brought up during cold reset).
-   Default is 0. If the platform always brings up a single CPU, there is no
-   need to distinguish between primary and secondary CPUs and the boot path can
-   be optimised. The ``plat_is_my_cpu_primary()`` and
-   ``plat_secondary_cold_boot_setup()`` platform porting interfaces do not need
-   to be implemented in this case.
-
--  ``CRASH_REPORTING``: A non-zero value enables a console dump of processor
-   register state when an unexpected exception occurs during execution of
-   BL31. This option defaults to the value of ``DEBUG`` - i.e. by default
-   this is only enabled for a debug build of the firmware.
-
--  ``CREATE_KEYS``: This option is used when ``GENERATE_COT=1``. It tells the
-   certificate generation tool to create new keys in case no valid keys are
-   present or specified. Allowed options are '0' or '1'. Default is '1'.
-
--  ``CTX_INCLUDE_AARCH32_REGS`` : Boolean option that, when set to 1, will cause
-   the AArch32 system registers to be included when saving and restoring the
-   CPU context. The option must be set to 0 for AArch64-only platforms (that
-   is on hardware that does not implement AArch32, or at least not at EL1 and
-   higher ELs). Default value is 1.
-
--  ``CTX_INCLUDE_FPREGS``: Boolean option that, when set to 1, will cause the FP
-   registers to be included when saving and restoring the CPU context. Default
-   is 0.
-
--  ``CTX_INCLUDE_MTE_REGS``: Enables register saving/reloading support for
-   ARMv8.5 Memory Tagging Extension. A value of 0 will disable
-   saving/reloading and restrict the use of MTE to the normal world if the
-   CPU has support, while a value of 1 enables the saving/reloading, allowing
-   the use of MTE in both the secure and non-secure worlds. Default is 0
-   (disabled) and this feature is experimental.
-
--  ``CTX_INCLUDE_PAUTH_REGS``: Boolean option that, when set to 1, enables
-   Pointer Authentication for Secure world. This will cause the ARMv8.3-PAuth
-   registers to be included when saving and restoring the CPU context as
-   part of world switch. Default value is 0 and this is an experimental feature.
-   Note that Pointer Authentication is enabled for Non-secure world irrespective
-   of the value of this flag if the CPU supports it.
-
--  ``DEBUG``: Chooses between a debug and release build. It can take either 0
-   (release) or 1 (debug) as values. 0 is the default.
-
--  ``DISABLE_BIN_GENERATION``: Boolean option to disable the generation
-   of the binary image. If set to 1, then only the ELF image is built.
-   0 is the default.
-
--  ``DYN_DISABLE_AUTH``: Provides the capability to dynamically disable Trusted
-   Board Boot authentication at runtime. This option is meant to be enabled only
-   for development platforms. ``TRUSTED_BOARD_BOOT`` flag must be set if this
-   flag has to be enabled. 0 is the default.
-
--  ``E``: Boolean option to make warnings into errors. Default is 1.
-
--  ``EL3_PAYLOAD_BASE``: This option enables booting an EL3 payload instead of
-   the normal boot flow. It must specify the entry point address of the EL3
-   payload. Please refer to the "Booting an EL3 payload" section for more
-   details.
-
--  ``ENABLE_AMU``: Boolean option to enable Activity Monitor Unit extensions.
-   This is an optional architectural feature available on v8.4 onwards. Some
-   v8.2 implementations also implement an AMU and this option can be used to
-   enable this feature on those systems as well. Default is 0.
-
--  ``ENABLE_ASSERTIONS``: This option controls whether or not calls to ``assert()``
-   are compiled out. For debug builds, this option defaults to 1, and calls to
-   ``assert()`` are left in place. For release builds, this option defaults to 0
-   and calls to ``assert()`` function are compiled out. This option can be set
-   independently of ``DEBUG``. It can also be used to hide any auxiliary code
-   that is only required for the assertion and does not fit in the assertion
-   itself.
-
--  ``ENABLE_BACKTRACE``: This option controls whether to enables backtrace
-   dumps or not. It is supported in both AArch64 and AArch32. However, in
-   AArch32 the format of the frame records are not defined in the AAPCS and they
-   are defined by the implementation. This implementation of backtrace only
-   supports the format used by GCC when T32 interworking is disabled. For this
-   reason enabling this option in AArch32 will force the compiler to only
-   generate A32 code. This option is enabled by default only in AArch64 debug
-   builds, but this behaviour can be overridden in each platform's Makefile or
-   in the build command line.
-
--  ``ENABLE_MPAM_FOR_LOWER_ELS``: Boolean option to enable lower ELs to use MPAM
-   feature. MPAM is an optional Armv8.4 extension that enables various memory
-   system components and resources to define partitions; software running at
-   various ELs can assign themselves to desired partition to control their
-   performance aspects.
-
-   When this option is set to ``1``, EL3 allows lower ELs to access their own
-   MPAM registers without trapping into EL3. This option doesn't make use of
-   partitioning in EL3, however. Platform initialisation code should configure
-   and use partitions in EL3 as required. This option defaults to ``0``.
-
--  ``ENABLE_PIE``: Boolean option to enable Position Independent Executable(PIE)
-   support within generic code in TF-A. This option is currently only supported
-   in BL31. Default is 0.
-
--  ``ENABLE_PMF``: Boolean option to enable support for optional Performance
-   Measurement Framework(PMF). Default is 0.
-
--  ``ENABLE_PSCI_STAT``: Boolean option to enable support for optional PSCI
-   functions ``PSCI_STAT_RESIDENCY`` and ``PSCI_STAT_COUNT``. Default is 0.
-   In the absence of an alternate stat collection backend, ``ENABLE_PMF`` must
-   be enabled. If ``ENABLE_PMF`` is set, the residency statistics are tracked in
-   software.
-
--  ``ENABLE_RUNTIME_INSTRUMENTATION``: Boolean option to enable runtime
-   instrumentation which injects timestamp collection points into TF-A to
-   allow runtime performance to be measured. Currently, only PSCI is
-   instrumented. Enabling this option enables the ``ENABLE_PMF`` build option
-   as well. Default is 0.
-
--  ``ENABLE_SPE_FOR_LOWER_ELS`` : Boolean option to enable Statistical Profiling
-   extensions. This is an optional architectural feature for AArch64.
-   The default is 1 but is automatically disabled when the target architecture
-   is AArch32.
-
--  ``ENABLE_SPM`` : Boolean option to enable the Secure Partition Manager (SPM).
-   Refer to :ref:`Secure Partition Manager` for more details about
-   this feature. Default is 0.
-
--  ``ENABLE_SVE_FOR_NS``: Boolean option to enable Scalable Vector Extension
-   (SVE) for the Non-secure world only. SVE is an optional architectural feature
-   for AArch64. Note that when SVE is enabled for the Non-secure world, access
-   to SIMD and floating-point functionality from the Secure world is disabled.
-   This is to avoid corruption of the Non-secure world data in the Z-registers
-   which are aliased by the SIMD and FP registers. The build option is not
-   compatible with the ``CTX_INCLUDE_FPREGS`` build option, and will raise an
-   assert on platforms where SVE is implemented and ``ENABLE_SVE_FOR_NS`` set to
-   1. The default is 1 but is automatically disabled when the target
-   architecture is AArch32.
-
--  ``ENABLE_STACK_PROTECTOR``: String option to enable the stack protection
-   checks in GCC. Allowed values are "all", "strong", "default" and "none". The
-   default value is set to "none". "strong" is the recommended stack protection
-   level if this feature is desired. "none" disables the stack protection. For
-   all values other than "none", the ``plat_get_stack_protector_canary()``
-   platform hook needs to be implemented. The value is passed as the last
-   component of the option ``-fstack-protector-$ENABLE_STACK_PROTECTOR``.
-
--  ``ERROR_DEPRECATED``: This option decides whether to treat the usage of
-   deprecated platform APIs, helper functions or drivers within Trusted
-   Firmware as error. It can take the value 1 (flag the use of deprecated
-   APIs as error) or 0. The default is 0.
-
--  ``EL3_EXCEPTION_HANDLING``: When set to ``1``, enable handling of exceptions
-   targeted at EL3. When set ``0`` (default), no exceptions are expected or
-   handled at EL3, and a panic will result. This is supported only for AArch64
-   builds.
-
--  ``FAULT_INJECTION_SUPPORT``: ARMv8.4 extensions introduced support for fault
-   injection from lower ELs, and this build option enables lower ELs to use
-   Error Records accessed via System Registers to inject faults. This is
-   applicable only to AArch64 builds.
-
-   This feature is intended for testing purposes only, and is advisable to keep
-   disabled for production images.
-
--  ``FIP_NAME``: This is an optional build option which specifies the FIP
-   filename for the ``fip`` target. Default is ``fip.bin``.
-
--  ``FWU_FIP_NAME``: This is an optional build option which specifies the FWU
-   FIP filename for the ``fwu_fip`` target. Default is ``fwu_fip.bin``.
-
--  ``GENERATE_COT``: Boolean flag used to build and execute the ``cert_create``
-   tool to create certificates as per the Chain of Trust described in
-   :ref:`Trusted Board Boot`. The build system then calls ``fiptool`` to
-   include the certificates in the FIP and FWU_FIP. Default value is '0'.
-
-   Specify both ``TRUSTED_BOARD_BOOT=1`` and ``GENERATE_COT=1`` to include support
-   for the Trusted Board Boot feature in the BL1 and BL2 images, to generate
-   the corresponding certificates, and to include those certificates in the
-   FIP and FWU_FIP.
-
-   Note that if ``TRUSTED_BOARD_BOOT=0`` and ``GENERATE_COT=1``, the BL1 and BL2
-   images will not include support for Trusted Board Boot. The FIP will still
-   include the corresponding certificates. This FIP can be used to verify the
-   Chain of Trust on the host machine through other mechanisms.
-
-   Note that if ``TRUSTED_BOARD_BOOT=1`` and ``GENERATE_COT=0``, the BL1 and BL2
-   images will include support for Trusted Board Boot, but the FIP and FWU_FIP
-   will not include the corresponding certificates, causing a boot failure.
-
--  ``GICV2_G0_FOR_EL3``: Unlike GICv3, the GICv2 architecture doesn't have
-   inherent support for specific EL3 type interrupts. Setting this build option
-   to ``1`` assumes GICv2 *Group 0* interrupts are expected to target EL3, both
-   by `platform abstraction layer`__ and `Interrupt Management Framework`__.
-   This allows GICv2 platforms to enable features requiring EL3 interrupt type.
-   This also means that all GICv2 Group 0 interrupts are delivered to EL3, and
-   the Secure Payload interrupts needs to be synchronously handed over to Secure
-   EL1 for handling. The default value of this option is ``0``, which means the
-   Group 0 interrupts are assumed to be handled by Secure EL1.
-
-   .. __: `platform-interrupt-controller-API.rst`
-   .. __: `interrupt-framework-design.rst`
-
--  ``HANDLE_EA_EL3_FIRST``: When set to ``1``, External Aborts and SError
-   Interrupts will be always trapped in EL3 i.e. in BL31 at runtime. When set to
-   ``0`` (default), these exceptions will be trapped in the current exception
-   level (or in EL1 if the current exception level is EL0).
-
--  ``HW_ASSISTED_COHERENCY``: On most Arm systems to-date, platform-specific
-   software operations are required for CPUs to enter and exit coherency.
-   However, newer systems exist where CPUs' entry to and exit from coherency
-   is managed in hardware. Such systems require software to only initiate these
-   operations, and the rest is managed in hardware, minimizing active software
-   management. In such systems, this boolean option enables TF-A to carry out
-   build and run-time optimizations during boot and power management operations.
-   This option defaults to 0 and if it is enabled, then it implies
-   ``WARMBOOT_ENABLE_DCACHE_EARLY`` is also enabled.
-
-   If this flag is disabled while the platform which TF-A is compiled for
-   includes cores that manage coherency in hardware, then a compilation error is
-   generated. This is based on the fact that a system cannot have, at the same
-   time, cores that manage coherency in hardware and cores that don't. In other
-   words, a platform cannot have, at the same time, cores that require
-   ``HW_ASSISTED_COHERENCY=1`` and cores that require
-   ``HW_ASSISTED_COHERENCY=0``.
-
-   Note that, when ``HW_ASSISTED_COHERENCY`` is enabled, version 2 of
-   translation library (xlat tables v2) must be used; version 1 of translation
-   library is not supported.
-
--  ``JUNO_AARCH32_EL3_RUNTIME``: This build flag enables you to execute EL3
-   runtime software in AArch32 mode, which is required to run AArch32 on Juno.
-   By default this flag is set to '0'. Enabling this flag builds BL1 and BL2 in
-   AArch64 and facilitates the loading of ``SP_MIN`` and BL33 as AArch32 executable
-   images.
-
--  ``KEY_ALG``: This build flag enables the user to select the algorithm to be
-   used for generating the PKCS keys and subsequent signing of the certificate.
-   It accepts 2 values: ``rsa`` and ``ecdsa``. The default value of this flag
-   is ``rsa`` which is the TBBR compliant PKCS#1 RSA 2.1 scheme.
-
--  ``KEY_SIZE``: This build flag enables the user to select the key size for
-   the algorithm specified by ``KEY_ALG``. The valid values for ``KEY_SIZE``
-   depend on the chosen algorithm.
-
-   +-----------+------------------------------------+
-   |  KEY_ALG  |        Possible key sizes          |
-   +===========+====================================+
-   |    rsa    |  1024, 2048 (default), 3072, 4096  |
-   +-----------+------------------------------------+
-   |   ecdsa   |            unavailable             |
-   +-----------+------------------------------------+
-
--  ``HASH_ALG``: This build flag enables the user to select the secure hash
-   algorithm. It accepts 3 values: ``sha256``, ``sha384`` and ``sha512``.
-   The default value of this flag is ``sha256``.
-
--  ``LDFLAGS``: Extra user options appended to the linkers' command line in
-   addition to the one set by the build system.
-
--  ``LOG_LEVEL``: Chooses the log level, which controls the amount of console log
-   output compiled into the build. This should be one of the following:
-
-   ::
-
-       0  (LOG_LEVEL_NONE)
-       10 (LOG_LEVEL_ERROR)
-       20 (LOG_LEVEL_NOTICE)
-       30 (LOG_LEVEL_WARNING)
-       40 (LOG_LEVEL_INFO)
-       50 (LOG_LEVEL_VERBOSE)
-
-   All log output up to and including the selected log level is compiled into
-   the build. The default value is 40 in debug builds and 20 in release builds.
-
--  ``NON_TRUSTED_WORLD_KEY``: This option is used when ``GENERATE_COT=1``. It
-   specifies the file that contains the Non-Trusted World private key in PEM
-   format. If ``SAVE_KEYS=1``, this file name will be used to save the key.
-
--  ``NS_BL2U``: Path to NS_BL2U image in the host file system. This image is
-   optional. It is only needed if the platform makefile specifies that it
-   is required in order to build the ``fwu_fip`` target.
-
--  ``NS_TIMER_SWITCH``: Enable save and restore for non-secure timer register
-   contents upon world switch. It can take either 0 (don't save and restore) or
-   1 (do save and restore). 0 is the default. An SPD may set this to 1 if it
-   wants the timer registers to be saved and restored.
-
--  ``OVERRIDE_LIBC``: This option allows platforms to override the default libc
-   for the BL image. It can be either 0 (include) or 1 (remove). The default
-   value is 0.
-
--  ``PL011_GENERIC_UART``: Boolean option to indicate the PL011 driver that
-   the underlying hardware is not a full PL011 UART but a minimally compliant
-   generic UART, which is a subset of the PL011. The driver will not access
-   any register that is not part of the SBSA generic UART specification.
-   Default value is 0 (a full PL011 compliant UART is present).
-
--  ``PLAT``: Choose a platform to build TF-A for. The chosen platform name
-   must be subdirectory of any depth under ``plat/``, and must contain a
-   platform makefile named ``platform.mk``. For example, to build TF-A for the
-   Arm Juno board, select PLAT=juno.
-
--  ``PRELOADED_BL33_BASE``: This option enables booting a preloaded BL33 image
-   instead of the normal boot flow. When defined, it must specify the entry
-   point address for the preloaded BL33 image. This option is incompatible with
-   ``EL3_PAYLOAD_BASE``. If both are defined, ``EL3_PAYLOAD_BASE`` has priority
-   over ``PRELOADED_BL33_BASE``.
-
--  ``PROGRAMMABLE_RESET_ADDRESS``: This option indicates whether the reset
-   vector address can be programmed or is fixed on the platform. It can take
-   either 0 (fixed) or 1 (programmable). Default is 0. If the platform has a
-   programmable reset address, it is expected that a CPU will start executing
-   code directly at the right address, both on a cold and warm reset. In this
-   case, there is no need to identify the entrypoint on boot and the boot path
-   can be optimised. The ``plat_get_my_entrypoint()`` platform porting interface
-   does not need to be implemented in this case.
-
--  ``PSCI_EXTENDED_STATE_ID``: As per PSCI1.0 Specification, there are 2 formats
-   possible for the PSCI power-state parameter: original and extended State-ID
-   formats. This flag if set to 1, configures the generic PSCI layer to use the
-   extended format. The default value of this flag is 0, which means by default
-   the original power-state format is used by the PSCI implementation. This flag
-   should be specified by the platform makefile and it governs the return value
-   of PSCI_FEATURES API for CPU_SUSPEND smc function id. When this option is
-   enabled on Arm platforms, the option ``ARM_RECOM_STATE_ID_ENC`` needs to be
-   set to 1 as well.
-
--  ``RAS_EXTENSION``: When set to ``1``, enable Armv8.2 RAS features. RAS features
-   are an optional extension for pre-Armv8.2 CPUs, but are mandatory for Armv8.2
-   or later CPUs.
-
-   When ``RAS_EXTENSION`` is set to ``1``, ``HANDLE_EA_EL3_FIRST`` must also be
-   set to ``1``.
-
-   This option is disabled by default.
-
--  ``RESET_TO_BL31``: Enable BL31 entrypoint as the CPU reset vector instead
-   of the BL1 entrypoint. It can take the value 0 (CPU reset to BL1
-   entrypoint) or 1 (CPU reset to BL31 entrypoint).
-   The default value is 0.
-
--  ``RESET_TO_SP_MIN``: SP_MIN is the minimal AArch32 Secure Payload provided
-   in TF-A. This flag configures SP_MIN entrypoint as the CPU reset vector
-   instead of the BL1 entrypoint. It can take the value 0 (CPU reset to BL1
-   entrypoint) or 1 (CPU reset to SP_MIN entrypoint). The default value is 0.
-
--  ``ROT_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
-   file that contains the ROT private key in PEM format. If ``SAVE_KEYS=1``, this
-   file name will be used to save the key.
-
--  ``SANITIZE_UB``: This option enables the Undefined Behaviour sanitizer. It
-   can take 3 values: 'off' (default), 'on' and 'trap'. When using 'trap',
-   gcc and clang will insert calls to ``__builtin_trap`` on detected
-   undefined behaviour, which defaults to a ``brk`` instruction. When using
-   'on', undefined behaviour is translated to a call to special handlers which
-   prints the exact location of the problem and its cause and then panics.
-
-    .. note::
-        Because of the space penalty of the Undefined Behaviour sanitizer,
-        this option will increase the size of the binary. Depending on the
-        memory constraints of the target platform, it may not be possible to
-        enable the sanitizer for all images (BL1 and BL2 are especially
-        likely to be memory constrained). We recommend that the
-        sanitizer is enabled only in debug builds.
-
--  ``SAVE_KEYS``: This option is used when ``GENERATE_COT=1``. It tells the
-   certificate generation tool to save the keys used to establish the Chain of
-   Trust. Allowed options are '0' or '1'. Default is '0' (do not save).
-
--  ``SCP_BL2``: Path to SCP_BL2 image in the host file system. This image is optional.
-   If a SCP_BL2 image is present then this option must be passed for the ``fip``
-   target.
-
--  ``SCP_BL2_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
-   file that contains the SCP_BL2 private key in PEM format. If ``SAVE_KEYS=1``,
-   this file name will be used to save the key.
-
--  ``SCP_BL2U``: Path to SCP_BL2U image in the host file system. This image is
-   optional. It is only needed if the platform makefile specifies that it
-   is required in order to build the ``fwu_fip`` target.
-
--  ``SDEI_SUPPORT``: Setting this to ``1`` enables support for Software
-   Delegated Exception Interface to BL31 image. This defaults to ``0``.
-
-   When set to ``1``, the build option ``EL3_EXCEPTION_HANDLING`` must also be
-   set to ``1``.
-
--  ``SEPARATE_CODE_AND_RODATA``: Whether code and read-only data should be
-   isolated on separate memory pages. This is a trade-off between security and
-   memory usage. See "Isolating code and read-only data on separate memory
-   pages" section in :ref:`Firmware Design`. This flag is disabled by default
-   and affects all BL images.
-
--  ``SPD``: Choose a Secure Payload Dispatcher component to be built into TF-A.
-   This build option is only valid if ``ARCH=aarch64``. The value should be
-   the path to the directory containing the SPD source, relative to
-   ``services/spd/``; the directory is expected to contain a makefile called
-   ``<spd-value>.mk``.
-
--  ``SPIN_ON_BL1_EXIT``: This option introduces an infinite loop in BL1. It can
-   take either 0 (no loop) or 1 (add a loop). 0 is the default. This loop stops
-   execution in BL1 just before handing over to BL31. At this point, all
-   firmware images have been loaded in memory, and the MMU and caches are
-   turned off. Refer to the "Debugging options" section for more details.
-
--  ``SP_MIN_WITH_SECURE_FIQ``: Boolean flag to indicate the SP_MIN handles
-   secure interrupts (caught through the FIQ line). Platforms can enable
-   this directive if they need to handle such interruption. When enabled,
-   the FIQ are handled in monitor mode and non secure world is not allowed
-   to mask these events. Platforms that enable FIQ handling in SP_MIN shall
-   implement the api ``sp_min_plat_fiq_handler()``. The default value is 0.
-
--  ``TRUSTED_BOARD_BOOT``: Boolean flag to include support for the Trusted Board
-   Boot feature. When set to '1', BL1 and BL2 images include support to load
-   and verify the certificates and images in a FIP, and BL1 includes support
-   for the Firmware Update. The default value is '0'. Generation and inclusion
-   of certificates in the FIP and FWU_FIP depends upon the value of the
-   ``GENERATE_COT`` option.
-
-   .. warning::
-      This option depends on ``CREATE_KEYS`` to be enabled. If the keys
-      already exist in disk, they will be overwritten without further notice.
-
--  ``TRUSTED_WORLD_KEY``: This option is used when ``GENERATE_COT=1``. It
-   specifies the file that contains the Trusted World private key in PEM
-   format. If ``SAVE_KEYS=1``, this file name will be used to save the key.
-
--  ``TSP_INIT_ASYNC``: Choose BL32 initialization method as asynchronous or
-   synchronous, (see "Initializing a BL32 Image" section in
-   :ref:`Firmware Design`). It can take the value 0 (BL32 is initialized using
-   synchronous method) or 1 (BL32 is initialized using asynchronous method).
-   Default is 0.
-
--  ``TSP_NS_INTR_ASYNC_PREEMPT``: A non zero value enables the interrupt
-   routing model which routes non-secure interrupts asynchronously from TSP
-   to EL3 causing immediate preemption of TSP. The EL3 is responsible
-   for saving and restoring the TSP context in this routing model. The
-   default routing model (when the value is 0) is to route non-secure
-   interrupts to TSP allowing it to save its context and hand over
-   synchronously to EL3 via an SMC.
-
-   .. note::
-      When ``EL3_EXCEPTION_HANDLING`` is ``1``, ``TSP_NS_INTR_ASYNC_PREEMPT``
-      must also be set to ``1``.
-
--  ``USE_ARM_LINK``: This flag determines whether to enable support for ARM
-   linker. When the ``LINKER`` build variable points to the armlink linker,
-   this flag is enabled automatically. To enable support for armlink, platforms
-   will have to provide a scatter file for the BL image. Currently, Tegra
-   platforms use the armlink support to compile BL3-1 images.
-
--  ``USE_COHERENT_MEM``: This flag determines whether to include the coherent
-   memory region in the BL memory map or not (see "Use of Coherent memory in
-   TF-A" section in :ref:`Firmware Design`). It can take the value 1
-   (Coherent memory region is included) or 0 (Coherent memory region is
-   excluded). Default is 1.
-
--  ``USE_ROMLIB``: This flag determines whether library at ROM will be used.
-   This feature creates a library of functions to be placed in ROM and thus
-   reduces SRAM usage. Refer to :ref:`Library at ROM` for further details.
-   Default is 0.
-
--  ``USE_SPINLOCK_CAS``: Setting this build flag to 1 selects the spinlock
-    implementation variant using the ARMv8.1-LSE compare-and-swap instruction.
-    Notice this option is experimental and only available to AArch64 builds.
-
--  ``V``: Verbose build. If assigned anything other than 0, the build commands
-   are printed. Default is 0.
-
--  ``VERSION_STRING``: String used in the log output for each TF-A image.
-   Defaults to a string formed by concatenating the version number, build type
-   and build string.
-
--  ``W``: Warning level. Some compiler warning options of interest have been
-   regrouped and put in the root Makefile. This flag can take the values 0 to 3,
-   each level enabling more warning options. Default is 0.
-
--  ``WARMBOOT_ENABLE_DCACHE_EARLY`` : Boolean option to enable D-cache early on
-   the CPU after warm boot. This is applicable for platforms which do not
-   require interconnect programming to enable cache coherency (eg: single
-   cluster platforms). If this option is enabled, then warm boot path
-   enables D-caches immediately after enabling MMU. This option defaults to 0.
-
-Arm development platform specific build options
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
--  ``ARM_BL31_IN_DRAM``: Boolean option to select loading of BL31 in TZC secured
-   DRAM. By default, BL31 is in the secure SRAM. Set this flag to 1 to load
-   BL31 in TZC secured DRAM. If TSP is present, then setting this option also
-   sets the TSP location to DRAM and ignores the ``ARM_TSP_RAM_LOCATION`` build
-   flag.
-
--  ``ARM_CONFIG_CNTACR``: boolean option to unlock access to the ``CNTBase<N>``
-   frame registers by setting the ``CNTCTLBase.CNTACR<N>`` register bits. The
-   frame number ``<N>`` is defined by ``PLAT_ARM_NSTIMER_FRAME_ID``, which should
-   match the frame used by the Non-Secure image (normally the Linux kernel).
-   Default is true (access to the frame is allowed).
-
--  ``ARM_DISABLE_TRUSTED_WDOG``: boolean option to disable the Trusted Watchdog.
-   By default, Arm platforms use a watchdog to trigger a system reset in case
-   an error is encountered during the boot process (for example, when an image
-   could not be loaded or authenticated). The watchdog is enabled in the early
-   platform setup hook at BL1 and disabled in the BL1 prepare exit hook. The
-   Trusted Watchdog may be disabled at build time for testing or development
-   purposes.
-
--  ``ARM_LINUX_KERNEL_AS_BL33``: The Linux kernel expects registers x0-x3 to
-   have specific values at boot. This boolean option allows the Trusted Firmware
-   to have a Linux kernel image as BL33 by preparing the registers to these
-   values before jumping to BL33. This option defaults to 0 (disabled). For
-   AArch64 ``RESET_TO_BL31`` and for AArch32 ``RESET_TO_SP_MIN`` must be 1 when
-   using it. If this option is set to 1, ``ARM_PRELOADED_DTB_BASE`` must be set
-   to the location of a device tree blob (DTB) already loaded in memory. The
-   Linux Image address must be specified using the ``PRELOADED_BL33_BASE``
-   option.
-
--  ``ARM_PLAT_MT``: This flag determines whether the Arm platform layer has to
-   cater for the multi-threading ``MT`` bit when accessing MPIDR. When this flag
-   is set, the functions which deal with MPIDR assume that the ``MT`` bit in
-   MPIDR is set and access the bit-fields in MPIDR accordingly. Default value of
-   this flag is 0. Note that this option is not used on FVP platforms.
-
--  ``ARM_RECOM_STATE_ID_ENC``: The PSCI1.0 specification recommends an encoding
-   for the construction of composite state-ID in the power-state parameter.
-   The existing PSCI clients currently do not support this encoding of
-   State-ID yet. Hence this flag is used to configure whether to use the
-   recommended State-ID encoding or not. The default value of this flag is 0,
-   in which case the platform is configured to expect NULL in the State-ID
-   field of power-state parameter.
-
--  ``ARM_ROTPK_LOCATION``: used when ``TRUSTED_BOARD_BOOT=1``. It specifies the
-   location of the ROTPK hash returned by the function ``plat_get_rotpk_info()``
-   for Arm platforms. Depending on the selected option, the proper private key
-   must be specified using the ``ROT_KEY`` option when building the Trusted
-   Firmware. This private key will be used by the certificate generation tool
-   to sign the BL2 and Trusted Key certificates. Available options for
-   ``ARM_ROTPK_LOCATION`` are:
-
-   -  ``regs`` : return the ROTPK hash stored in the Trusted root-key storage
-      registers. The private key corresponding to this ROTPK hash is not
-      currently available.
-   -  ``devel_rsa`` : return a development public key hash embedded in the BL1
-      and BL2 binaries. This hash has been obtained from the RSA public key
-      ``arm_rotpk_rsa.der``, located in ``plat/arm/board/common/rotpk``. To use
-      this option, ``arm_rotprivk_rsa.pem`` must be specified as ``ROT_KEY`` when
-      creating the certificates.
-   -  ``devel_ecdsa`` : return a development public key hash embedded in the BL1
-      and BL2 binaries. This hash has been obtained from the ECDSA public key
-      ``arm_rotpk_ecdsa.der``, located in ``plat/arm/board/common/rotpk``. To use
-      this option, ``arm_rotprivk_ecdsa.pem`` must be specified as ``ROT_KEY``
-      when creating the certificates.
-
--  ``ARM_TSP_RAM_LOCATION``: location of the TSP binary. Options:
-
-   -  ``tsram`` : Trusted SRAM (default option when TBB is not enabled)
-   -  ``tdram`` : Trusted DRAM (if available)
-   -  ``dram`` : Secure region in DRAM (default option when TBB is enabled,
-      configured by the TrustZone controller)
-
--  ``ARM_XLAT_TABLES_LIB_V1``: boolean option to compile TF-A with version 1
-   of the translation tables library instead of version 2. It is set to 0 by
-   default, which selects version 2.
-
--  ``ARM_CRYPTOCELL_INTEG`` : bool option to enable TF-A to invoke Arm®
-   TrustZone® CryptoCell functionality for Trusted Board Boot on capable Arm
-   platforms. If this option is specified, then the path to the CryptoCell
-   SBROM library must be specified via ``CCSBROM_LIB_PATH`` flag.
-
-For a better understanding of these options, the Arm development platform memory
-map is explained in the :ref:`Firmware Design`.
-
-Arm CSS platform specific build options
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
--  ``CSS_DETECT_PRE_1_7_0_SCP``: Boolean flag to detect SCP version
-   incompatibility. Version 1.7.0 of the SCP firmware made a non-backwards
-   compatible change to the MTL protocol, used for AP/SCP communication.
-   TF-A no longer supports earlier SCP versions. If this option is set to 1
-   then TF-A will detect if an earlier version is in use. Default is 1.
-
--  ``CSS_LOAD_SCP_IMAGES``: Boolean flag, which when set, adds SCP_BL2 and
-   SCP_BL2U to the FIP and FWU_FIP respectively, and enables them to be loaded
-   during boot. Default is 1.
-
--  ``CSS_USE_SCMI_SDS_DRIVER``: Boolean flag which selects SCMI/SDS drivers
-   instead of SCPI/BOM driver for communicating with the SCP during power
-   management operations and for SCP RAM Firmware transfer. If this option
-   is set to 1, then SCMI/SDS drivers will be used. Default is 0.
-
-Arm FVP platform specific build options
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
--  ``FVP_CLUSTER_COUNT`` : Configures the cluster count to be used to
-   build the topology tree within TF-A. By default TF-A is configured for dual
-   cluster topology and this option can be used to override the default value.
-
--  ``FVP_INTERCONNECT_DRIVER``: Selects the interconnect driver to be built. The
-   default interconnect driver depends on the value of ``FVP_CLUSTER_COUNT`` as
-   explained in the options below:
-
-   -  ``FVP_CCI`` : The CCI driver is selected. This is the default
-      if 0 < ``FVP_CLUSTER_COUNT`` <= 2.
-   -  ``FVP_CCN`` : The CCN driver is selected. This is the default
-      if ``FVP_CLUSTER_COUNT`` > 2.
-
--  ``FVP_MAX_CPUS_PER_CLUSTER``: Sets the maximum number of CPUs implemented in
-   a single cluster.  This option defaults to 4.
-
--  ``FVP_MAX_PE_PER_CPU``: Sets the maximum number of PEs implemented on any CPU
-   in the system. This option defaults to 1. Note that the build option
-   ``ARM_PLAT_MT`` doesn't have any effect on FVP platforms.
-
--  ``FVP_USE_GIC_DRIVER`` : Selects the GIC driver to be built. Options:
-
-   -  ``FVP_GIC600`` : The GIC600 implementation of GICv3 is selected
-   -  ``FVP_GICV2`` : The GICv2 only driver is selected
-   -  ``FVP_GICV3`` : The GICv3 only driver is selected (default option)
-
--  ``FVP_USE_SP804_TIMER`` : Use the SP804 timer instead of the Generic Timer
-   for functions that wait for an arbitrary time length (udelay and mdelay).
-   The default value is 0.
-
--  ``FVP_HW_CONFIG_DTS`` : Specify the path to the DTS file to be compiled
-   to DTB and packaged in FIP as the HW_CONFIG. See :ref:`Firmware Design` for
-   details on HW_CONFIG. By default, this is initialized to a sensible DTS
-   file in ``fdts/`` folder depending on other build options. But some cases,
-   like shifted affinity format for MPIDR, cannot be detected at build time
-   and this option is needed to specify the appropriate DTS file.
-
--  ``FVP_HW_CONFIG`` : Specify the path to the HW_CONFIG blob to be packaged in
-   FIP. See :ref:`Firmware Design` for details on HW_CONFIG. This option is
-   similar to the ``FVP_HW_CONFIG_DTS`` option, but it directly specifies the
-   HW_CONFIG blob instead of the DTS file. This option is useful to override
-   the default HW_CONFIG selected by the build system.
-
-ARM JUNO platform specific build options
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
--  ``JUNO_TZMP1`` : Boolean option to configure Juno to be used for TrustZone
-   Media Protection (TZ-MP1). Default value of this flag is 0.
-
-Debugging options
-~~~~~~~~~~~~~~~~~
-
-To compile a debug version and make the build more verbose use
-
-.. code:: shell
-
-    make PLAT=<platform> DEBUG=1 V=1 all
-
-AArch64 GCC uses DWARF version 4 debugging symbols by default. Some tools (for
-example DS-5) might not support this and may need an older version of DWARF
-symbols to be emitted by GCC. This can be achieved by using the
-``-gdwarf-<version>`` flag, with the version being set to 2 or 3. Setting the
-version to 2 is recommended for DS-5 versions older than 5.16.
-
-When debugging logic problems it might also be useful to disable all compiler
-optimizations by using ``-O0``.
-
-.. warning::
-   Using ``-O0`` could cause output images to be larger and base addresses
-   might need to be recalculated (see the **Memory layout on Arm development
-   platforms** section in the :ref:`Firmware Design`).
-
-Extra debug options can be passed to the build system by setting ``CFLAGS`` or
-``LDFLAGS``:
-
-.. code:: shell
-
-    CFLAGS='-O0 -gdwarf-2'                                     \
-    make PLAT=<platform> DEBUG=1 V=1 all
-
-Note that using ``-Wl,`` style compilation driver options in ``CFLAGS`` will be
-ignored as the linker is called directly.
-
-It is also possible to introduce an infinite loop to help in debugging the
-post-BL2 phase of TF-A. This can be done by rebuilding BL1 with the
-``SPIN_ON_BL1_EXIT=1`` build flag. Refer to the `Summary of build options`_
-section. In this case, the developer may take control of the target using a
-debugger when indicated by the console output. When using DS-5, the following
-commands can be used:
-
-::
-
-    # Stop target execution
-    interrupt
-
-    #
-    # Prepare your debugging environment, e.g. set breakpoints
-    #
-
-    # Jump over the debug loop
-    set var $AARCH64::$Core::$PC = $AARCH64::$Core::$PC + 4
-
-    # Resume execution
-    continue
-
-Building the Test Secure Payload
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The TSP is coupled with a companion runtime service in the BL31 firmware,
-called the TSPD. Therefore, if you intend to use the TSP, the BL31 image
-must be recompiled as well. For more information on SPs and SPDs, see the
-:ref:`Secure-EL1 Payloads and Dispatchers <firmware_design_sel1_spd>` section
-in the :ref:`Firmware Design` document.
-
-First clean the TF-A build directory to get rid of any previous BL31 binary.
-Then to build the TSP image use:
-
-.. code:: shell
-
-    make PLAT=<platform> SPD=tspd all
-
-An additional boot loader binary file is created in the ``build`` directory:
-
-::
-
-    build/<platform>/<build-type>/bl32.bin
-
-
-Building and using the FIP tool
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Firmware Image Package (FIP) is a packaging format used by TF-A to package
-firmware images in a single binary. The number and type of images that should
-be packed in a FIP is platform specific and may include TF-A images and other
-firmware images required by the platform. For example, most platforms require
-a BL33 image which corresponds to the normal world bootloader (e.g. UEFI or
-U-Boot).
-
-The TF-A build system provides the make target ``fip`` to create a FIP file
-for the specified platform using the FIP creation tool included in the TF-A
-project. Examples below show how to build a FIP file for FVP, packaging TF-A
-and BL33 images.
-
-For AArch64:
-
-.. code:: shell
-
-    make PLAT=fvp BL33=<path-to>/bl33.bin fip
-
-For AArch32:
-
-.. code:: shell
-
-    make PLAT=fvp ARCH=aarch32 AARCH32_SP=sp_min BL33=<path-to>/bl33.bin fip
-
-The resulting FIP may be found in:
-
-::
-
-    build/fvp/<build-type>/fip.bin
-
-For advanced operations on FIP files, it is also possible to independently build
-the tool and create or modify FIPs using this tool. To do this, follow these
-steps:
-
-It is recommended to remove old artifacts before building the tool:
-
-.. code:: shell
-
-    make -C tools/fiptool clean
-
-Build the tool:
-
-.. code:: shell
-
-    make [DEBUG=1] [V=1] fiptool
-
-The tool binary can be located in:
-
-::
-
-    ./tools/fiptool/fiptool
-
-Invoking the tool with ``help`` will print a help message with all available
-options.
-
-Example 1: create a new Firmware package ``fip.bin`` that contains BL2 and BL31:
-
-.. code:: shell
-
-    ./tools/fiptool/fiptool create \
-        --tb-fw build/<platform>/<build-type>/bl2.bin \
-        --soc-fw build/<platform>/<build-type>/bl31.bin \
-        fip.bin
-
-Example 2: view the contents of an existing Firmware package:
-
-.. code:: shell
-
-    ./tools/fiptool/fiptool info <path-to>/fip.bin
-
-Example 3: update the entries of an existing Firmware package:
-
-.. code:: shell
-
-    # Change the BL2 from Debug to Release version
-    ./tools/fiptool/fiptool update \
-        --tb-fw build/<platform>/release/bl2.bin \
-        build/<platform>/debug/fip.bin
-
-Example 4: unpack all entries from an existing Firmware package:
-
-.. code:: shell
-
-    # Images will be unpacked to the working directory
-    ./tools/fiptool/fiptool unpack <path-to>/fip.bin
-
-Example 5: remove an entry from an existing Firmware package:
-
-.. code:: shell
-
-    ./tools/fiptool/fiptool remove \
-        --tb-fw build/<platform>/debug/fip.bin
-
-Note that if the destination FIP file exists, the create, update and
-remove operations will automatically overwrite it.
-
-The unpack operation will fail if the images already exist at the
-destination. In that case, use -f or --force to continue.
-
-More information about FIP can be found in the :ref:`Firmware Design` document.
-
-Building FIP images with support for Trusted Board Boot
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Trusted Board Boot primarily consists of the following two features:
-
--  Image Authentication, described in :ref:`Trusted Board Boot`, and
--  Firmware Update, described in :ref:`Firmware Update (FWU)`
-
-The following steps should be followed to build FIP and (optionally) FWU_FIP
-images with support for these features:
-
-#. Fulfill the dependencies of the ``mbedtls`` cryptographic and image parser
-   modules by checking out a recent version of the `mbed TLS Repository`_. It
-   is important to use a version that is compatible with TF-A and fixes any
-   known security vulnerabilities. See `mbed TLS Security Center`_ for more
-   information. The latest version of TF-A is tested with tag
-   ``mbedtls-2.16.2``.
-
-   The ``drivers/auth/mbedtls/mbedtls_*.mk`` files contain the list of mbed TLS
-   source files the modules depend upon.
-   ``include/drivers/auth/mbedtls/mbedtls_config.h`` contains the configuration
-   options required to build the mbed TLS sources.
-
-   Note that the mbed TLS library is licensed under the Apache version 2.0
-   license. Using mbed TLS source code will affect the licensing of TF-A
-   binaries that are built using this library.
-
-#. To build the FIP image, ensure the following command line variables are set
-   while invoking ``make`` to build TF-A:
-
-   -  ``MBEDTLS_DIR=<path of the directory containing mbed TLS sources>``
-   -  ``TRUSTED_BOARD_BOOT=1``
-   -  ``GENERATE_COT=1``
-
-   In the case of Arm platforms, the location of the ROTPK hash must also be
-   specified at build time. Two locations are currently supported (see
-   ``ARM_ROTPK_LOCATION`` build option):
-
-   -  ``ARM_ROTPK_LOCATION=regs``: the ROTPK hash is obtained from the Trusted
-      root-key storage registers present in the platform. On Juno, this
-      registers are read-only. On FVP Base and Cortex models, the registers
-      are read-only, but the value can be specified using the command line
-      option ``bp.trusted_key_storage.public_key`` when launching the model.
-      On both Juno and FVP models, the default value corresponds to an
-      ECDSA-SECP256R1 public key hash, whose private part is not currently
-      available.
-
-   -  ``ARM_ROTPK_LOCATION=devel_rsa``: use the ROTPK hash that is hardcoded
-      in the Arm platform port. The private/public RSA key pair may be
-      found in ``plat/arm/board/common/rotpk``.
-
-   -  ``ARM_ROTPK_LOCATION=devel_ecdsa``: use the ROTPK hash that is hardcoded
-      in the Arm platform port. The private/public ECDSA key pair may be
-      found in ``plat/arm/board/common/rotpk``.
-
-   Example of command line using RSA development keys:
-
-   .. code:: shell
-
-       MBEDTLS_DIR=<path of the directory containing mbed TLS sources> \
-       make PLAT=<platform> TRUSTED_BOARD_BOOT=1 GENERATE_COT=1        \
-       ARM_ROTPK_LOCATION=devel_rsa                                    \
-       ROT_KEY=plat/arm/board/common/rotpk/arm_rotprivk_rsa.pem        \
-       BL33=<path-to>/<bl33_image>                                     \
-       all fip
-
-   The result of this build will be the bl1.bin and the fip.bin binaries. This
-   FIP will include the certificates corresponding to the Chain of Trust
-   described in the TBBR-client document. These certificates can also be found
-   in the output build directory.
-
-#. The optional FWU_FIP contains any additional images to be loaded from
-   Non-Volatile storage during the :ref:`Firmware Update (FWU)` process. To
-   build the FWU_FIP, any FWU images required by the platform must be specified
-   on the command line. On Arm development platforms like Juno, these are:
-
-   -  NS_BL2U. The AP non-secure Firmware Updater image.
-   -  SCP_BL2U. The SCP Firmware Update Configuration image.
-
-   Example of Juno command line for generating both ``fwu`` and ``fwu_fip``
-   targets using RSA development:
-
-   ::
-
-       MBEDTLS_DIR=<path of the directory containing mbed TLS sources> \
-       make PLAT=juno TRUSTED_BOARD_BOOT=1 GENERATE_COT=1              \
-       ARM_ROTPK_LOCATION=devel_rsa                                    \
-       ROT_KEY=plat/arm/board/common/rotpk/arm_rotprivk_rsa.pem        \
-       BL33=<path-to>/<bl33_image>                                     \
-       SCP_BL2=<path-to>/<scp_bl2_image>                               \
-       SCP_BL2U=<path-to>/<scp_bl2u_image>                             \
-       NS_BL2U=<path-to>/<ns_bl2u_image>                               \
-       all fip fwu_fip
-
-   .. note::
-      The BL2U image will be built by default and added to the FWU_FIP.
-      The user may override this by adding ``BL2U=<path-to>/<bl2u_image>``
-      to the command line above.
-
-   .. note::
-      Building and installing the non-secure and SCP FWU images (NS_BL1U,
-      NS_BL2U and SCP_BL2U) is outside the scope of this document.
-
-   The result of this build will be bl1.bin, fip.bin and fwu_fip.bin binaries.
-   Both the FIP and FWU_FIP will include the certificates corresponding to the
-   Chain of Trust described in the TBBR-client document. These certificates
-   can also be found in the output build directory.
-
-Building the Certificate Generation Tool
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The ``cert_create`` tool is built as part of the TF-A build process when the
-``fip`` make target is specified and TBB is enabled (as described in the
-previous section), but it can also be built separately with the following
-command:
-
-.. code:: shell
-
-    make PLAT=<platform> [DEBUG=1] [V=1] certtool
-
-For platforms that require their own IDs in certificate files, the generic
-'cert_create' tool can be built with the following command. Note that the target
-platform must define its IDs within a ``platform_oid.h`` header file for the
-build to succeed.
-
-.. code:: shell
-
-    make PLAT=<platform> USE_TBBR_DEFS=0 [DEBUG=1] [V=1] certtool
-
-``DEBUG=1`` builds the tool in debug mode. ``V=1`` makes the build process more
-verbose. The following command should be used to obtain help about the tool:
-
-.. code:: shell
-
-    ./tools/cert_create/cert_create -h
-
-Building a FIP for Juno and FVP
--------------------------------
-
-This section provides Juno and FVP specific instructions to build Trusted
-Firmware, obtain the additional required firmware, and pack it all together in
-a single FIP binary. It assumes that a `Linaro Release`_ has been installed.
-
-.. note::
-   Pre-built binaries for AArch32 are available from Linaro Release 16.12
-   onwards. Before that release, pre-built binaries are only available for
-   AArch64.
-
-.. warning::
-   Follow the full instructions for one platform before switching to a
-   different one. Mixing instructions for different platforms may result in
-   corrupted binaries.
-
-.. warning::
-   The uboot image downloaded by the Linaro workspace script does not always
-   match the uboot image packaged as BL33 in the corresponding fip file. It is
-   recommended to use the version that is packaged in the fip file using the
-   instructions below.
-
-.. note::
-   For the FVP, the kernel FDT is packaged in FIP during build and loaded
-   by the firmware at runtime. See `Obtaining the Flattened Device Trees`_
-   section for more info on selecting the right FDT to use.
-
-#. Clean the working directory
-
-   .. code:: shell
-
-       make realclean
-
-#. Obtain SCP_BL2 (Juno) and BL33 (all platforms)
-
-   Use the fiptool to extract the SCP_BL2 and BL33 images from the FIP
-   package included in the Linaro release:
-
-   .. code:: shell
-
-       # Build the fiptool
-       make [DEBUG=1] [V=1] fiptool
-
-       # Unpack firmware images from Linaro FIP
-       ./tools/fiptool/fiptool unpack <path-to-linaro-release>/[SOFTWARE]/fip.bin
-
-   The unpack operation will result in a set of binary images extracted to the
-   current working directory. The SCP_BL2 image corresponds to
-   ``scp-fw.bin`` and BL33 corresponds to ``nt-fw.bin``.
-
-   .. note::
-      The fiptool will complain if the images to be unpacked already
-      exist in the current directory. If that is the case, either delete those
-      files or use the ``--force`` option to overwrite.
-
-   .. note::
-      For AArch32, the instructions below assume that nt-fw.bin is a
-      normal world boot loader that supports AArch32.
-
-#. Build TF-A images and create a new FIP for FVP
-
-   .. code:: shell
-
-       # AArch64
-       make PLAT=fvp BL33=nt-fw.bin all fip
-
-       # AArch32
-       make PLAT=fvp ARCH=aarch32 AARCH32_SP=sp_min BL33=nt-fw.bin all fip
-
-#. Build TF-A images and create a new FIP for Juno
-
-   For AArch64:
-
-   Building for AArch64 on Juno simply requires the addition of ``SCP_BL2``
-   as a build parameter.
-
-   .. code:: shell
-
-       make PLAT=juno BL33=nt-fw.bin SCP_BL2=scp-fw.bin all fip
-
-   For AArch32:
-
-   Hardware restrictions on Juno prevent cold reset into AArch32 execution mode,
-   therefore BL1 and BL2 must be compiled for AArch64, and BL32 is compiled
-   separately for AArch32.
-
-   -  Before building BL32, the environment variable ``CROSS_COMPILE`` must point
-      to the AArch32 cross compiler.
-
-      .. code:: shell
-
-          export CROSS_COMPILE=<path-to-aarch32-gcc>/bin/arm-eabi-
-
-   -  Build BL32 in AArch32.
-
-      .. code:: shell
-
-          make ARCH=aarch32 PLAT=juno AARCH32_SP=sp_min \
-          RESET_TO_SP_MIN=1 JUNO_AARCH32_EL3_RUNTIME=1 bl32
-
-   -  Save ``bl32.bin`` to a temporary location and clean the build products.
-
-      ::
-
-          cp <path-to-build>/bl32.bin <path-to-temporary>
-          make realclean
-
-   -  Before building BL1 and BL2, the environment variable ``CROSS_COMPILE``
-      must point to the AArch64 cross compiler.
-
-      .. code:: shell
-
-          export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-linux-gnu-
-
-   -  The following parameters should be used to build BL1 and BL2 in AArch64
-      and point to the BL32 file.
-
-      .. code:: shell
-
-          make ARCH=aarch64 PLAT=juno JUNO_AARCH32_EL3_RUNTIME=1 \
-          BL33=nt-fw.bin SCP_BL2=scp-fw.bin \
-          BL32=<path-to-temporary>/bl32.bin all fip
-
-The resulting BL1 and FIP images may be found in:
-
-::
-
-    # Juno
-    ./build/juno/release/bl1.bin
-    ./build/juno/release/fip.bin
-
-    # FVP
-    ./build/fvp/release/bl1.bin
-    ./build/fvp/release/fip.bin
-
-
-Booting Firmware Update images
--------------------------------------
-
-When Firmware Update (FWU) is enabled there are at least 2 new images
-that have to be loaded, the Non-Secure FWU ROM (NS-BL1U), and the
-FWU FIP.
-
-Juno
-~~~~
-
-The new images must be programmed in flash memory by adding
-an entry in the ``SITE1/HBI0262x/images.txt`` configuration file
-on the Juno SD card (where ``x`` depends on the revision of the Juno board).
-Refer to the `Juno Getting Started Guide`_, section 2.3 "Flash memory
-programming" for more information. User should ensure these do not
-overlap with any other entries in the file.
-
-::
-
-	NOR10UPDATE: AUTO                       ;Image Update:NONE/AUTO/FORCE
-	NOR10ADDRESS: 0x00400000                ;Image Flash Address [ns_bl2u_base_address]
-	NOR10FILE: \SOFTWARE\fwu_fip.bin        ;Image File Name
-	NOR10LOAD: 00000000                     ;Image Load Address
-	NOR10ENTRY: 00000000                    ;Image Entry Point
-
-	NOR11UPDATE: AUTO                       ;Image Update:NONE/AUTO/FORCE
-	NOR11ADDRESS: 0x03EB8000                ;Image Flash Address [ns_bl1u_base_address]
-	NOR11FILE: \SOFTWARE\ns_bl1u.bin        ;Image File Name
-	NOR11LOAD: 00000000                     ;Image Load Address
-
-The address ns_bl1u_base_address is the value of NS_BL1U_BASE - 0x8000000.
-In the same way, the address ns_bl2u_base_address is the value of
-NS_BL2U_BASE - 0x8000000.
-
-FVP
-~~~
-
-The additional fip images must be loaded with:
-
-::
-
-    --data cluster0.cpu0="<path_to>/ns_bl1u.bin"@0x0beb8000	[ns_bl1u_base_address]
-    --data cluster0.cpu0="<path_to>/fwu_fip.bin"@0x08400000	[ns_bl2u_base_address]
-
-The address ns_bl1u_base_address is the value of NS_BL1U_BASE.
-In the same way, the address ns_bl2u_base_address is the value of
-NS_BL2U_BASE.
-
-
-EL3 payloads alternative boot flow
-----------------------------------
-
-On a pre-production system, the ability to execute arbitrary, bare-metal code at
-the highest exception level is required. It allows full, direct access to the
-hardware, for example to run silicon soak tests.
-
-Although it is possible to implement some baremetal secure firmware from
-scratch, this is a complex task on some platforms, depending on the level of
-configuration required to put the system in the expected state.
-
-Rather than booting a baremetal application, a possible compromise is to boot
-``EL3 payloads`` through TF-A instead. This is implemented as an alternative
-boot flow, where a modified BL2 boots an EL3 payload, instead of loading the
-other BL images and passing control to BL31. It reduces the complexity of
-developing EL3 baremetal code by:
-
--  putting the system into a known architectural state;
--  taking care of platform secure world initialization;
--  loading the SCP_BL2 image if required by the platform.
-
-When booting an EL3 payload on Arm standard platforms, the configuration of the
-TrustZone controller is simplified such that only region 0 is enabled and is
-configured to permit secure access only. This gives full access to the whole
-DRAM to the EL3 payload.
-
-The system is left in the same state as when entering BL31 in the default boot
-flow. In particular:
-
--  Running in EL3;
--  Current state is AArch64;
--  Little-endian data access;
--  All exceptions disabled;
--  MMU disabled;
--  Caches disabled.
-
-Booting an EL3 payload
-~~~~~~~~~~~~~~~~~~~~~~
-
-The EL3 payload image is a standalone image and is not part of the FIP. It is
-not loaded by TF-A. Therefore, there are 2 possible scenarios:
-
--  The EL3 payload may reside in non-volatile memory (NVM) and execute in
-   place. In this case, booting it is just a matter of specifying the right
-   address in NVM through ``EL3_PAYLOAD_BASE`` when building TF-A.
-
--  The EL3 payload needs to be loaded in volatile memory (e.g. DRAM) at
-   run-time.
-
-To help in the latter scenario, the ``SPIN_ON_BL1_EXIT=1`` build option can be
-used. The infinite loop that it introduces in BL1 stops execution at the right
-moment for a debugger to take control of the target and load the payload (for
-example, over JTAG).
-
-It is expected that this loading method will work in most cases, as a debugger
-connection is usually available in a pre-production system. The user is free to
-use any other platform-specific mechanism to load the EL3 payload, though.
-
-Booting an EL3 payload on FVP
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The EL3 payloads boot flow requires the CPU's mailbox to be cleared at reset for
-the secondary CPUs holding pen to work properly. Unfortunately, its reset value
-is undefined on the FVP platform and the FVP platform code doesn't clear it.
-Therefore, one must modify the way the model is normally invoked in order to
-clear the mailbox at start-up.
-
-One way to do that is to create an 8-byte file containing all zero bytes using
-the following command:
-
-.. code:: shell
-
-    dd if=/dev/zero of=mailbox.dat bs=1 count=8
-
-and pre-load it into the FVP memory at the mailbox address (i.e. ``0x04000000``)
-using the following model parameters:
-
-::
-
-    --data cluster0.cpu0=mailbox.dat@0x04000000   [Base FVPs]
-    --data=mailbox.dat@0x04000000                 [Foundation FVP]
-
-To provide the model with the EL3 payload image, the following methods may be
-used:
-
-#. If the EL3 payload is able to execute in place, it may be programmed into
-   flash memory. On Base Cortex and AEM FVPs, the following model parameter
-   loads it at the base address of the NOR FLASH1 (the NOR FLASH0 is already
-   used for the FIP):
-
-   ::
-
-       -C bp.flashloader1.fname="<path-to>/<el3-payload>"
-
-   On Foundation FVP, there is no flash loader component and the EL3 payload
-   may be programmed anywhere in flash using method 3 below.
-
-#. When using the ``SPIN_ON_BL1_EXIT=1`` loading method, the following DS-5
-   command may be used to load the EL3 payload ELF image over JTAG:
-
-   ::
-
-       load <path-to>/el3-payload.elf
-
-#. The EL3 payload may be pre-loaded in volatile memory using the following
-   model parameters:
-
-   ::
-
-       --data cluster0.cpu0="<path-to>/el3-payload>"@address   [Base FVPs]
-       --data="<path-to>/<el3-payload>"@address                [Foundation FVP]
-
-   The address provided to the FVP must match the ``EL3_PAYLOAD_BASE`` address
-   used when building TF-A.
-
-Booting an EL3 payload on Juno
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-If the EL3 payload is able to execute in place, it may be programmed in flash
-memory by adding an entry in the ``SITE1/HBI0262x/images.txt`` configuration file
-on the Juno SD card (where ``x`` depends on the revision of the Juno board).
-Refer to the `Juno Getting Started Guide`_, section 2.3 "Flash memory
-programming" for more information.
-
-Alternatively, the same DS-5 command mentioned in the FVP section above can
-be used to load the EL3 payload's ELF file over JTAG on Juno.
-
-Preloaded BL33 alternative boot flow
-------------------------------------
-
-Some platforms have the ability to preload BL33 into memory instead of relying
-on TF-A to load it. This may simplify packaging of the normal world code and
-improve performance in a development environment. When secure world cold boot
-is complete, TF-A simply jumps to a BL33 base address provided at build time.
-
-For this option to be used, the ``PRELOADED_BL33_BASE`` build option has to be
-used when compiling TF-A. For example, the following command will create a FIP
-without a BL33 and prepare to jump to a BL33 image loaded at address
-0x80000000:
-
-.. code:: shell
-
-    make PRELOADED_BL33_BASE=0x80000000 PLAT=fvp all fip
-
-Boot of a preloaded kernel image on Base FVP
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The following example uses a simplified boot flow by directly jumping from the
-TF-A to the Linux kernel, which will use a ramdisk as filesystem. This can be
-useful if both the kernel and the device tree blob (DTB) are already present in
-memory (like in FVP).
-
-For example, if the kernel is loaded at ``0x80080000`` and the DTB is loaded at
-address ``0x82000000``, the firmware can be built like this:
-
-.. code:: shell
-
-    CROSS_COMPILE=aarch64-linux-gnu-  \
-    make PLAT=fvp DEBUG=1             \
-    RESET_TO_BL31=1                   \
-    ARM_LINUX_KERNEL_AS_BL33=1        \
-    PRELOADED_BL33_BASE=0x80080000    \
-    ARM_PRELOADED_DTB_BASE=0x82000000 \
-    all fip
-
-Now, it is needed to modify the DTB so that the kernel knows the address of the
-ramdisk. The following script generates a patched DTB from the provided one,
-assuming that the ramdisk is loaded at address ``0x84000000``. Note that this
-script assumes that the user is using a ramdisk image prepared for U-Boot, like
-the ones provided by Linaro. If using a ramdisk without this header,the ``0x40``
-offset in ``INITRD_START`` has to be removed.
-
-.. code:: bash
-
-    #!/bin/bash
-
-    # Path to the input DTB
-    KERNEL_DTB=<path-to>/<fdt>
-    # Path to the output DTB
-    PATCHED_KERNEL_DTB=<path-to>/<patched-fdt>
-    # Base address of the ramdisk
-    INITRD_BASE=0x84000000
-    # Path to the ramdisk
-    INITRD=<path-to>/<ramdisk.img>
-
-    # Skip uboot header (64 bytes)
-    INITRD_START=$(printf "0x%x" $((${INITRD_BASE} + 0x40)) )
-    INITRD_SIZE=$(stat -Lc %s ${INITRD})
-    INITRD_END=$(printf "0x%x" $((${INITRD_BASE} + ${INITRD_SIZE})) )
-
-    CHOSEN_NODE=$(echo                                        \
-    "/ {                                                      \
-            chosen {                                          \
-                    linux,initrd-start = <${INITRD_START}>;   \
-                    linux,initrd-end = <${INITRD_END}>;       \
-            };                                                \
-    };")
-
-    echo $(dtc -O dts -I dtb ${KERNEL_DTB}) ${CHOSEN_NODE} |  \
-            dtc -O dtb -o ${PATCHED_KERNEL_DTB} -
-
-And the FVP binary can be run with the following command:
-
-.. code:: shell

-Arm FVPs without shifted affinities, and that do not support threaded CPU cores
-(64-bit host machine only).
-
--  ``FVP_Base_AEMv8A-AEMv8A``
--  ``FVP_Base_Cortex-A32x4``
-
-.. note::
-   The ``FVP_Base_RevC-2xAEMv8A`` FVP only supports shifted affinities, which
-   is not compatible with legacy GIC configurations. Therefore this FVP does not
-   support these legacy GIC configurations.
-
-.. note::
-   The build numbers quoted above are those reported by launching the FVP
-   with the ``--version`` parameter.
-
-.. note::
-   Linaro provides a ramdisk image in prebuilt FVP configurations and full
-   file systems that can be downloaded separately. To run an FVP with a virtio
-   file system image an additional FVP configuration option
-   ``-C bp.virtioblockdevice.image_path="<path-to>/<file-system-image>`` can be
-   used.
-
-.. note::
-   The software will not work on Version 1.0 of the Foundation FVP.
-   The commands below would report an ``unhandled argument`` error in this case.
-
-.. note::
-   FVPs can be launched with ``--cadi-server`` option such that a
-   CADI-compliant debugger (for example, Arm DS-5) can connect to and control
-   its execution.
-
-.. warning::
-   Since FVP model Version 11.0 Build 11.0.34 and Version 8.5 Build 0.8.5202
-   the internal synchronisation timings changed compared to older versions of
-   the models. The models can be launched with ``-Q 100`` option if they are
-   required to match the run time characteristics of the older versions.
-
-The Foundation FVP is a cut down version of the AArch64 Base FVP. It can be
-downloaded for free from `Arm's website`_.
-
-The Cortex-A models listed above are also available to download from
-`Arm's website`_.
-
-Please refer to the FVP documentation for a detailed description of the model
-parameter options. A brief description of the important ones that affect TF-A
-and normal world software behavior is provided below.
-
-Obtaining the Flattened Device Trees
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Depending on the FVP configuration and Linux configuration used, different
-FDT files are required. FDT source files for the Foundation and Base FVPs can
-be found in the TF-A source directory under ``fdts/``. The Foundation FVP has
-a subset of the Base FVP components. For example, the Foundation FVP lacks
-CLCD and MMC support, and has only one CPU cluster.
-
-.. note::
-   It is not recommended to use the FDTs built along the kernel because not
-   all FDTs are available from there.
-
-The dynamic configuration capability is enabled in the firmware for FVPs.
-This means that the firmware can authenticate and load the FDT if present in
-FIP. A default FDT is packaged into FIP during the build based on
-the build configuration. This can be overridden by using the ``FVP_HW_CONFIG``
-or ``FVP_HW_CONFIG_DTS`` build options (refer to the
-`Arm FVP platform specific build options`_ section for detail on the options).

-Notes:
-
--  BL1 is loaded at the start of the Trusted ROM.
--  The Firmware Image Package is loaded at the start of NOR FLASH0.
--  The firmware loads the FDT packaged in FIP to the DRAM. The FDT load address
-   is specified via the ``hw_config_addr`` property in ``TB_FW_CONFIG`` for FVP.
--  The default use-case for the Foundation FVP is to use the ``--gicv3`` option
-   and enable the GICv3 device in the model. Note that without this option,
-   the Foundation FVP defaults to legacy (Versatile Express) memory map which
-   is not supported by TF-A.
--  In order for TF-A to run correctly on the Foundation FVP, the architecture
-   versions must match. The Foundation FVP defaults to the highest v8.x
-   version it supports but the default build for TF-A is for v8.0. To avoid
-   issues either start the Foundation FVP to use v8.0 architecture using the
-   ``--arm-v8.0`` option, or build TF-A with an appropriate value for
-   ``ARM_ARCH_MINOR``.

-Notes:
-
--  If Position Independent Executable (PIE) support is enabled for BL31
-   in this config, it can be loaded at any valid address for execution.
-
--  Since a FIP is not loaded when using BL31 as reset entrypoint, the
-   ``--data="<path-to><bl31|bl32|bl33-binary>"@<base-address-of-binary>``
-   parameter is needed to load the individual bootloader images in memory.
-   BL32 image is only needed if BL31 has been built to expect a Secure-EL1
-   Payload. For the same reason, the FDT needs to be compiled from the DT source
-   and loaded via the ``--data cluster0.cpu0="<path-to>/<fdt>"@0x82000000``
-   parameter.
-
--  The ``FVP_Base_RevC-2xAEMv8A`` has shifted affinities and requires a
-   specific DTS for all the CPUs to be loaded.
-
--  The ``-C cluster<X>.cpu<Y>.RVBAR=@<base-address-of-bl31>`` parameter, where
-   X and Y are the cluster and CPU numbers respectively, is used to set the
-   reset vector for each core.
-
--  Changing the default value of ``ARM_TSP_RAM_LOCATION`` will also require
-   changing the value of
-   ``--data="<path-to><bl32-binary>"@<base-address-of-bl32>`` to the new value of
-   ``BL32_BASE``.

-Running the software on Juno
-----------------------------
-
-This version of TF-A has been tested on variants r0, r1 and r2 of Juno.
-
-To execute the software stack on Juno, installing the latest Arm Platforms
-software deliverables is recommended. Please install the deliverables by
-following the `Instructions for using Linaro's deliverables on Juno`_.
-
-Preparing TF-A images
-~~~~~~~~~~~~~~~~~~~~~
-
-After building TF-A, the files ``bl1.bin`` and ``fip.bin`` need copying to the
-``SOFTWARE/`` directory of the Juno SD card.
-
-Other Juno software information
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Please visit the `Arm Platforms Portal`_ to get support and obtain any other Juno
-software information. Please also refer to the `Juno Getting Started Guide`_ to
-get more detailed information about the Juno Arm development platform and how to
-configure it.
-
-Testing SYSTEM SUSPEND on Juno
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The SYSTEM SUSPEND is a PSCI API which can be used to implement system suspend
-to RAM. For more details refer to section 5.16 of `PSCI`_. To test system suspend
-on Juno, at the linux shell prompt, issue the following command:
-
-.. code:: shell
-
-    echo +10 > /sys/class/rtc/rtc0/wakealarm
-    echo -n mem > /sys/power/state
-
-The Juno board should suspend to RAM and then wakeup after 10 seconds due to
-wakeup interrupt from RTC.

+Test Secure Payload (TSP) and Dispatcher (TSPD)
+===============================================
+
+Building the Test Secure Payload
+--------------------------------
+
+The TSP is coupled with a companion runtime service in the BL31 firmware,
+called the TSPD. Therefore, if you intend to use the TSP, the BL31 image
+must be recompiled as well. For more information on SPs and SPDs, see the
+:ref:`firmware_design_sel1_spd` section in the :ref:`Firmware Design`.
+
+First clean the TF-A build directory to get rid of any previous BL31 binary.
+Then to build the TSP image use:
+
+.. code:: shell
+
+    make PLAT=<platform> SPD=tspd all
+
+An additional boot loader binary file is created in the ``build`` directory:
+
+::
+
+    build/<platform>/<build-type>/bl32.bin

+Arm Development Platform Build Options
+======================================
+
+Arm Platform Build Options
+--------------------------
+
+-  ``ARM_BL31_IN_DRAM``: Boolean option to select loading of BL31 in TZC secured
+   DRAM. By default, BL31 is in the secure SRAM. Set this flag to 1 to load
+   BL31 in TZC secured DRAM. If TSP is present, then setting this option also
+   sets the TSP location to DRAM and ignores the ``ARM_TSP_RAM_LOCATION`` build
+   flag.
+
+-  ``ARM_CONFIG_CNTACR``: boolean option to unlock access to the ``CNTBase<N>``
+   frame registers by setting the ``CNTCTLBase.CNTACR<N>`` register bits. The
+   frame number ``<N>`` is defined by ``PLAT_ARM_NSTIMER_FRAME_ID``, which
+   should match the frame used by the Non-Secure image (normally the Linux
+   kernel). Default is true (access to the frame is allowed).
+
+-  ``ARM_DISABLE_TRUSTED_WDOG``: boolean option to disable the Trusted Watchdog.
+   By default, Arm platforms use a watchdog to trigger a system reset in case
+   an error is encountered during the boot process (for example, when an image
+   could not be loaded or authenticated). The watchdog is enabled in the early
+   platform setup hook at BL1 and disabled in the BL1 prepare exit hook. The
+   Trusted Watchdog may be disabled at build time for testing or development
+   purposes.
+
+-  ``ARM_LINUX_KERNEL_AS_BL33``: The Linux kernel expects registers x0-x3 to
+   have specific values at boot. This boolean option allows the Trusted Firmware
+   to have a Linux kernel image as BL33 by preparing the registers to these
+   values before jumping to BL33. This option defaults to 0 (disabled). For
+   AArch64 ``RESET_TO_BL31`` and for AArch32 ``RESET_TO_SP_MIN`` must be 1 when
+   using it. If this option is set to 1, ``ARM_PRELOADED_DTB_BASE`` must be set
+   to the location of a device tree blob (DTB) already loaded in memory. The
+   Linux Image address must be specified using the ``PRELOADED_BL33_BASE``
+   option.
+
+-  ``ARM_PLAT_MT``: This flag determines whether the Arm platform layer has to
+   cater for the multi-threading ``MT`` bit when accessing MPIDR. When this flag
+   is set, the functions which deal with MPIDR assume that the ``MT`` bit in
+   MPIDR is set and access the bit-fields in MPIDR accordingly. Default value of
+   this flag is 0. Note that this option is not used on FVP platforms.
+
+-  ``ARM_RECOM_STATE_ID_ENC``: The PSCI1.0 specification recommends an encoding
+   for the construction of composite state-ID in the power-state parameter.
+   The existing PSCI clients currently do not support this encoding of
+   State-ID yet. Hence this flag is used to configure whether to use the
+   recommended State-ID encoding or not. The default value of this flag is 0,
+   in which case the platform is configured to expect NULL in the State-ID
+   field of power-state parameter.
+
+-  ``ARM_ROTPK_LOCATION``: used when ``TRUSTED_BOARD_BOOT=1``. It specifies the
+   location of the ROTPK hash returned by the function ``plat_get_rotpk_info()``
+   for Arm platforms. Depending on the selected option, the proper private key
+   must be specified using the ``ROT_KEY`` option when building the Trusted
+   Firmware. This private key will be used by the certificate generation tool
+   to sign the BL2 and Trusted Key certificates. Available options for
+   ``ARM_ROTPK_LOCATION`` are:
+
+   -  ``regs`` : return the ROTPK hash stored in the Trusted root-key storage
+      registers. The private key corresponding to this ROTPK hash is not
+      currently available.
+   -  ``devel_rsa`` : return a development public key hash embedded in the BL1
+      and BL2 binaries. This hash has been obtained from the RSA public key
+      ``arm_rotpk_rsa.der``, located in ``plat/arm/board/common/rotpk``. To use
+      this option, ``arm_rotprivk_rsa.pem`` must be specified as ``ROT_KEY``
+      when creating the certificates.
+   -  ``devel_ecdsa`` : return a development public key hash embedded in the BL1
+      and BL2 binaries. This hash has been obtained from the ECDSA public key
+      ``arm_rotpk_ecdsa.der``, located in ``plat/arm/board/common/rotpk``. To
+      use this option, ``arm_rotprivk_ecdsa.pem`` must be specified as
+      ``ROT_KEY`` when creating the certificates.
+
+-  ``ARM_TSP_RAM_LOCATION``: location of the TSP binary. Options:
+
+   -  ``tsram`` : Trusted SRAM (default option when TBB is not enabled)
+   -  ``tdram`` : Trusted DRAM (if available)
+   -  ``dram`` : Secure region in DRAM (default option when TBB is enabled,
+      configured by the TrustZone controller)
+
+-  ``ARM_XLAT_TABLES_LIB_V1``: boolean option to compile TF-A with version 1
+   of the translation tables library instead of version 2. It is set to 0 by
+   default, which selects version 2.
+
+-  ``ARM_CRYPTOCELL_INTEG`` : bool option to enable TF-A to invoke Arm®
+   TrustZone® CryptoCell functionality for Trusted Board Boot on capable Arm
+   platforms. If this option is specified, then the path to the CryptoCell
+   SBROM library must be specified via ``CCSBROM_LIB_PATH`` flag.
+
+For a better understanding of these options, the Arm development platform memory
+map is explained in the :ref:`Firmware Design`.
+
+.. _build_options_arm_css_platform:
+
+Arm CSS Platform-Specific Build Options
+---------------------------------------
+
+-  ``CSS_DETECT_PRE_1_7_0_SCP``: Boolean flag to detect SCP version
+   incompatibility. Version 1.7.0 of the SCP firmware made a non-backwards
+   compatible change to the MTL protocol, used for AP/SCP communication.
+   TF-A no longer supports earlier SCP versions. If this option is set to 1
+   then TF-A will detect if an earlier version is in use. Default is 1.
+
+-  ``CSS_LOAD_SCP_IMAGES``: Boolean flag, which when set, adds SCP_BL2 and
+   SCP_BL2U to the FIP and FWU_FIP respectively, and enables them to be loaded
+   during boot. Default is 1.
+
+-  ``CSS_USE_SCMI_SDS_DRIVER``: Boolean flag which selects SCMI/SDS drivers
+   instead of SCPI/BOM driver for communicating with the SCP during power
+   management operations and for SCP RAM Firmware transfer. If this option
+   is set to 1, then SCMI/SDS drivers will be used. Default is 0.

+Arm Fixed Virtual Platforms (FVP)
+=================================
+
+Fixed Virtual Platform (FVP) Support
+------------------------------------
+
+This section lists the supported Arm |FVP| platforms. Please refer to the FVP
+documentation for a detailed description of the model parameter options.
+
+The latest version of the AArch64 build of TF-A has been tested on the following
+Arm FVPs without shifted affinities, and that do not support threaded CPU cores
+(64-bit host machine only).
+

+-  ``Foundation_Platform``
+
+The latest version of the AArch32 build of TF-A has been tested on the
+following Arm FVPs without shifted affinities, and that do not support threaded
+CPU cores (64-bit host machine only).
+
+-  ``FVP_Base_AEMv8A-AEMv8A``
+-  ``FVP_Base_Cortex-A32x4``
+
+.. note::
+   The ``FVP_Base_RevC-2xAEMv8A`` FVP only supports shifted affinities, which
+   is not compatible with legacy GIC configurations. Therefore this FVP does not
+   support these legacy GIC configurations.
+
+The *Foundation* and *Base* FVPs can be downloaded free of charge. See the `Arm
+FVP website`_. The Cortex-A models listed above are also available to download
+from `Arm's website`_.
+
+.. note::
+   The build numbers quoted above are those reported by launching the FVP
+   with the ``--version`` parameter.
+
+.. note::
+   Linaro provides a ramdisk image in prebuilt FVP configurations and full
+   file systems that can be downloaded separately. To run an FVP with a virtio
+   file system image an additional FVP configuration option
+   ``-C bp.virtioblockdevice.image_path="<path-to>/<file-system-image>`` can be
+   used.
+
+.. note::
+   The software will not work on Version 1.0 of the Foundation FVP.
+   The commands below would report an ``unhandled argument`` error in this case.
+
+.. note::
+   FVPs can be launched with ``--cadi-server`` option such that a
+   CADI-compliant debugger (for example, Arm DS-5) can connect to and control
+   its execution.
+
+.. warning::
+   Since FVP model Version 11.0 Build 11.0.34 and Version 8.5 Build 0.8.5202
+   the internal synchronisation timings changed compared to older versions of
+   the models. The models can be launched with ``-Q 100`` option if they are
+   required to match the run time characteristics of the older versions.
+
+All the above platforms have been tested with `Linaro Release 19.06`_.
+
+.. _build_options_arm_fvp_platform:
+
+Arm FVP Platform Specific Build Options
+---------------------------------------
+
+-  ``FVP_CLUSTER_COUNT`` : Configures the cluster count to be used to
+   build the topology tree within TF-A. By default TF-A is configured for dual
+   cluster topology and this option can be used to override the default value.
+
+-  ``FVP_INTERCONNECT_DRIVER``: Selects the interconnect driver to be built. The
+   default interconnect driver depends on the value of ``FVP_CLUSTER_COUNT`` as
+   explained in the options below:
+
+   -  ``FVP_CCI`` : The CCI driver is selected. This is the default
+      if 0 < ``FVP_CLUSTER_COUNT`` <= 2.
+   -  ``FVP_CCN`` : The CCN driver is selected. This is the default
+      if ``FVP_CLUSTER_COUNT`` > 2.
+
+-  ``FVP_MAX_CPUS_PER_CLUSTER``: Sets the maximum number of CPUs implemented in
+   a single cluster.  This option defaults to 4.
+
+-  ``FVP_MAX_PE_PER_CPU``: Sets the maximum number of PEs implemented on any CPU
+   in the system. This option defaults to 1. Note that the build option
+   ``ARM_PLAT_MT`` doesn't have any effect on FVP platforms.
+
+-  ``FVP_USE_GIC_DRIVER`` : Selects the GIC driver to be built. Options:
+
+   -  ``FVP_GIC600`` : The GIC600 implementation of GICv3 is selected
+   -  ``FVP_GICV2`` : The GICv2 only driver is selected
+   -  ``FVP_GICV3`` : The GICv3 only driver is selected (default option)
+
+-  ``FVP_USE_SP804_TIMER`` : Use the SP804 timer instead of the Generic Timer
+   for functions that wait for an arbitrary time length (udelay and mdelay).
+   The default value is 0.
+
+-  ``FVP_HW_CONFIG_DTS`` : Specify the path to the DTS file to be compiled
+   to DTB and packaged in FIP as the HW_CONFIG. See :ref:`Firmware Design` for
+   details on HW_CONFIG. By default, this is initialized to a sensible DTS
+   file in ``fdts/`` folder depending on other build options. But some cases,
+   like shifted affinity format for MPIDR, cannot be detected at build time
+   and this option is needed to specify the appropriate DTS file.
+
+-  ``FVP_HW_CONFIG`` : Specify the path to the HW_CONFIG blob to be packaged in
+   FIP. See :ref:`Firmware Design` for details on HW_CONFIG. This option is
+   similar to the ``FVP_HW_CONFIG_DTS`` option, but it directly specifies the
+   HW_CONFIG blob instead of the DTS file. This option is useful to override
+   the default HW_CONFIG selected by the build system.
+
+Booting Firmware Update images
+------------------------------
+
+When Firmware Update (FWU) is enabled there are at least 2 new images
+that have to be loaded, the Non-Secure FWU ROM (NS-BL1U), and the
+FWU FIP.
+
+The additional fip images must be loaded with:
+
+::
+
+    --data cluster0.cpu0="<path_to>/ns_bl1u.bin"@0x0beb8000	[ns_bl1u_base_address]
+    --data cluster0.cpu0="<path_to>/fwu_fip.bin"@0x08400000	[ns_bl2u_base_address]
+
+The address ns_bl1u_base_address is the value of NS_BL1U_BASE.
+In the same way, the address ns_bl2u_base_address is the value of
+NS_BL2U_BASE.
+
+Booting an EL3 payload
+----------------------
+
+The EL3 payloads boot flow requires the CPU's mailbox to be cleared at reset for
+the secondary CPUs holding pen to work properly. Unfortunately, its reset value
+is undefined on the FVP platform and the FVP platform code doesn't clear it.
+Therefore, one must modify the way the model is normally invoked in order to
+clear the mailbox at start-up.
+
+One way to do that is to create an 8-byte file containing all zero bytes using
+the following command:
+
+.. code:: shell
+
+    dd if=/dev/zero of=mailbox.dat bs=1 count=8
+
+and pre-load it into the FVP memory at the mailbox address (i.e. ``0x04000000``)
+using the following model parameters:
+
+::
+
+    --data cluster0.cpu0=mailbox.dat@0x04000000   [Base FVPs]
+    --data=mailbox.dat@0x04000000                 [Foundation FVP]
+
+To provide the model with the EL3 payload image, the following methods may be
+used:
+
+#. If the EL3 payload is able to execute in place, it may be programmed into
+   flash memory. On Base Cortex and AEM FVPs, the following model parameter
+   loads it at the base address of the NOR FLASH1 (the NOR FLASH0 is already
+   used for the FIP):
+
+   ::
+
+       -C bp.flashloader1.fname="<path-to>/<el3-payload>"
+
+   On Foundation FVP, there is no flash loader component and the EL3 payload
+   may be programmed anywhere in flash using method 3 below.
+
+#. When using the ``SPIN_ON_BL1_EXIT=1`` loading method, the following DS-5
+   command may be used to load the EL3 payload ELF image over JTAG:
+
+   ::
+
+       load <path-to>/el3-payload.elf
+
+#. The EL3 payload may be pre-loaded in volatile memory using the following
+   model parameters:
+
+   ::
+
+       --data cluster0.cpu0="<path-to>/el3-payload>"@address   [Base FVPs]
+       --data="<path-to>/<el3-payload>"@address                [Foundation FVP]
+
+   The address provided to the FVP must match the ``EL3_PAYLOAD_BASE`` address
+   used when building TF-A.
+
+Booting a preloaded kernel image (Base FVP)
+-------------------------------------------
+
+The following example uses a simplified boot flow by directly jumping from the
+TF-A to the Linux kernel, which will use a ramdisk as filesystem. This can be
+useful if both the kernel and the device tree blob (DTB) are already present in
+memory (like in FVP).
+
+For example, if the kernel is loaded at ``0x80080000`` and the DTB is loaded at
+address ``0x82000000``, the firmware can be built like this:
+
+.. code:: shell
+
+    CROSS_COMPILE=aarch64-linux-gnu-  \
+    make PLAT=fvp DEBUG=1             \
+    RESET_TO_BL31=1                   \
+    ARM_LINUX_KERNEL_AS_BL33=1        \
+    PRELOADED_BL33_BASE=0x80080000    \
+    ARM_PRELOADED_DTB_BASE=0x82000000 \
+    all fip
+
+Now, it is needed to modify the DTB so that the kernel knows the address of the
+ramdisk. The following script generates a patched DTB from the provided one,
+assuming that the ramdisk is loaded at address ``0x84000000``. Note that this
+script assumes that the user is using a ramdisk image prepared for U-Boot, like
+the ones provided by Linaro. If using a ramdisk without this header,the ``0x40``
+offset in ``INITRD_START`` has to be removed.
+
+.. code:: bash
+
+    #!/bin/bash
+
+    # Path to the input DTB
+    KERNEL_DTB=<path-to>/<fdt>
+    # Path to the output DTB
+    PATCHED_KERNEL_DTB=<path-to>/<patched-fdt>
+    # Base address of the ramdisk
+    INITRD_BASE=0x84000000
+    # Path to the ramdisk
+    INITRD=<path-to>/<ramdisk.img>
+
+    # Skip uboot header (64 bytes)
+    INITRD_START=$(printf "0x%x" $((${INITRD_BASE} + 0x40)) )
+    INITRD_SIZE=$(stat -Lc %s ${INITRD})
+    INITRD_END=$(printf "0x%x" $((${INITRD_BASE} + ${INITRD_SIZE})) )
+
+    CHOSEN_NODE=$(echo                                        \
+    "/ {                                                      \
+            chosen {                                          \
+                    linux,initrd-start = <${INITRD_START}>;   \
+                    linux,initrd-end = <${INITRD_END}>;       \
+            };                                                \
+    };")
+
+    echo $(dtc -O dts -I dtb ${KERNEL_DTB}) ${CHOSEN_NODE} |  \
+            dtc -O dtb -o ${PATCHED_KERNEL_DTB} -
+
+And the FVP binary can be run with the following command:
+
+.. code:: shell
+
+    <path-to>/FVP_Base_AEMv8A-AEMv8A                            \
+    -C pctl.startup=0.0.0.0                                     \
+    -C bp.secure_memory=1                                       \
+    -C cluster0.NUM_CORES=4                                     \
+    -C cluster1.NUM_CORES=4                                     \
+    -C cache_state_modelled=1                                   \
+    -C cluster0.cpu0.RVBAR=0x04020000                           \

+    -C cluster0.cpu2.RVBAR=0x04020000                           \
+    -C cluster0.cpu3.RVBAR=0x04020000                           \
+    -C cluster1.cpu0.RVBAR=0x04020000                           \
+    -C cluster1.cpu1.RVBAR=0x04020000                           \
+    -C cluster1.cpu2.RVBAR=0x04020000                           \
+    -C cluster1.cpu3.RVBAR=0x04020000                           \

+    --data cluster0.cpu0="<path-to>/<ramdisk.img>"@0x84000000
+
+Obtaining the Flattened Device Trees
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Depending on the FVP configuration and Linux configuration used, different
+FDT files are required. FDT source files for the Foundation and Base FVPs can
+be found in the TF-A source directory under ``fdts/``. The Foundation FVP has
+a subset of the Base FVP components. For example, the Foundation FVP lacks
+CLCD and MMC support, and has only one CPU cluster.
+
+.. note::
+   It is not recommended to use the FDTs built along the kernel because not
+   all FDTs are available from there.
+
+The dynamic configuration capability is enabled in the firmware for FVPs.
+This means that the firmware can authenticate and load the FDT if present in
+FIP. A default FDT is packaged into FIP during the build based on
+the build configuration. This can be overridden by using the ``FVP_HW_CONFIG``
+or ``FVP_HW_CONFIG_DTS`` build options (refer to
+:ref:`build_options_arm_fvp_platform` for details on the options).
+

+-  BL1 is loaded at the start of the Trusted ROM.
+-  The Firmware Image Package is loaded at the start of NOR FLASH0.
+-  The firmware loads the FDT packaged in FIP to the DRAM. The FDT load address
+   is specified via the ``hw_config_addr`` property in `TB_FW_CONFIG for FVP`_.
+-  The default use-case for the Foundation FVP is to use the ``--gicv3`` option
+   and enable the GICv3 device in the model. Note that without this option,
+   the Foundation FVP defaults to legacy (Versatile Express) memory map which
+   is not supported by TF-A.
+-  In order for TF-A to run correctly on the Foundation FVP, the architecture
+   versions must match. The Foundation FVP defaults to the highest v8.x
+   version it supports but the default build for TF-A is for v8.0. To avoid
+   issues either start the Foundation FVP to use v8.0 architecture using the
+   ``--arm-v8.0`` option, or build TF-A with an appropriate value for
+   ``ARM_ARCH_MINOR``.

+
+Notes:
+
+-  If Position Independent Executable (PIE) support is enabled for BL31
+   in this config, it can be loaded at any valid address for execution.
+
+-  Since a FIP is not loaded when using BL31 as reset entrypoint, the
+   ``--data="<path-to><bl31|bl32|bl33-binary>"@<base-address-of-binary>``
+   parameter is needed to load the individual bootloader images in memory.
+   BL32 image is only needed if BL31 has been built to expect a Secure-EL1
+   Payload. For the same reason, the FDT needs to be compiled from the DT source
+   and loaded via the ``--data cluster0.cpu0="<path-to>/<fdt>"@0x82000000``
+   parameter.
+
+-  The ``FVP_Base_RevC-2xAEMv8A`` has shifted affinities and requires a
+   specific DTS for all the CPUs to be loaded.
+
+-  The ``-C cluster<X>.cpu<Y>.RVBAR=@<base-address-of-bl31>`` parameter, where
+   X and Y are the cluster and CPU numbers respectively, is used to set the
+   reset vector for each core.
+
+-  Changing the default value of ``ARM_TSP_RAM_LOCATION`` will also require
+   changing the value of
+   ``--data="<path-to><bl32-binary>"@<base-address-of-bl32>`` to the new value of
+   ``BL32_BASE``.

+Arm Juno Development Platform
+=============================
+
+Platform-specific build options
+-------------------------------
+
+-  ``JUNO_TZMP1`` : Boolean option to configure Juno to be used for TrustZone
+   Media Protection (TZ-MP1). Default value of this flag is 0.
+
+Running software on Juno
+------------------------
+
+This version of TF-A has been tested on variants r0, r1 and r2 of Juno.
+
+To execute the software stack on Juno, the version of the Juno board recovery
+image indicated in the `Linaro Release Notes`_ must be installed. If you have an
+earlier version installed or are unsure which version is installed, please
+re-install the recovery image by following the
+`Instructions for using Linaro's deliverables on Juno`_.
+
+Preparing TF-A images
+---------------------
+
+After building TF-A, the files ``bl1.bin`` and ``fip.bin`` need copying to the
+``SOFTWARE/`` directory of the Juno SD card.
+
+Creating a Firmware Image Package (FIP)
+---------------------------------------
+
+This section provides Juno and FVP specific instructions to build Trusted
+Firmware, obtain the additional required firmware, and pack it all together in
+a single FIP binary. It assumes that a Linaro release has been installed.
+
+.. note::
+   Pre-built binaries for AArch32 are available from Linaro Release 16.12
+   onwards. Before that release, pre-built binaries are only available for
+   AArch64.
+
+.. warning::
+   Follow the full instructions for one platform before switching to a
+   different one. Mixing instructions for different platforms may result in
+   corrupted binaries.
+
+.. warning::
+   The uboot image downloaded by the Linaro workspace script does not always
+   match the uboot image packaged as BL33 in the corresponding fip file. It is
+   recommended to use the version that is packaged in the fip file using the
+   instructions below.
+
+.. note::
+   For the FVP, the kernel FDT is packaged in FIP during build and loaded
+   by the firmware at runtime.
+
+#. Clean the working directory
+
+   .. code:: shell
+
+       make realclean
+
+#. Obtain SCP_BL2 (Juno) and BL33 (all platforms)
+
+   Use the fiptool to extract the SCP_BL2 and BL33 images from the FIP
+   package included in the Linaro release:
+
+   .. code:: shell
+
+       # Build the fiptool
+       make [DEBUG=1] [V=1] fiptool
+
+       # Unpack firmware images from Linaro FIP
+       ./tools/fiptool/fiptool unpack <path-to-linaro-release>/[SOFTWARE]/fip.bin
+
+   The unpack operation will result in a set of binary images extracted to the
+   current working directory. The SCP_BL2 image corresponds to
+   ``scp-fw.bin`` and BL33 corresponds to ``nt-fw.bin``.
+
+   .. note::
+      The fiptool will complain if the images to be unpacked already
+      exist in the current directory. If that is the case, either delete those
+      files or use the ``--force`` option to overwrite.
+
+   .. note::
+      For AArch32, the instructions below assume that nt-fw.bin is a
+      normal world boot loader that supports AArch32.
+
+#. Build TF-A images and create a new FIP for FVP
+
+   .. code:: shell
+
+       # AArch64
+       make PLAT=fvp BL33=nt-fw.bin all fip
+
+       # AArch32
+       make PLAT=fvp ARCH=aarch32 AARCH32_SP=sp_min BL33=nt-fw.bin all fip
+
+#. Build TF-A images and create a new FIP for Juno
+
+   For AArch64:
+
+   Building for AArch64 on Juno simply requires the addition of ``SCP_BL2``
+   as a build parameter.
+
+   .. code:: shell
+
+       make PLAT=juno BL33=nt-fw.bin SCP_BL2=scp-fw.bin all fip
+
+   For AArch32:
+
+   Hardware restrictions on Juno prevent cold reset into AArch32 execution mode,
+   therefore BL1 and BL2 must be compiled for AArch64, and BL32 is compiled
+   separately for AArch32.
+
+   -  Before building BL32, the environment variable ``CROSS_COMPILE`` must point
+      to the AArch32 Linaro cross compiler.
+
+      .. code:: shell
+
+          export CROSS_COMPILE=<path-to-aarch32-gcc>/bin/arm-linux-gnueabihf-
+
+   -  Build BL32 in AArch32.
+
+      .. code:: shell
+
+          make ARCH=aarch32 PLAT=juno AARCH32_SP=sp_min \
+          RESET_TO_SP_MIN=1 JUNO_AARCH32_EL3_RUNTIME=1 bl32
+
+   -  Save ``bl32.bin`` to a temporary location and clean the build products.
+
+      ::
+
+          cp <path-to-build>/bl32.bin <path-to-temporary>
+          make realclean
+
+   -  Before building BL1 and BL2, the environment variable ``CROSS_COMPILE``
+      must point to the AArch64 Linaro cross compiler.
+
+      .. code:: shell
+
+          export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-linux-gnu-
+
+   -  The following parameters should be used to build BL1 and BL2 in AArch64
+      and point to the BL32 file.
+
+      .. code:: shell
+
+          make ARCH=aarch64 PLAT=juno JUNO_AARCH32_EL3_RUNTIME=1 \
+          BL33=nt-fw.bin SCP_BL2=scp-fw.bin \
+          BL32=<path-to-temporary>/bl32.bin all fip
+
+The resulting BL1 and FIP images may be found in:
+
+::
+
+    # Juno
+    ./build/juno/release/bl1.bin
+    ./build/juno/release/fip.bin
+
+    # FVP
+    ./build/fvp/release/bl1.bin
+    ./build/fvp/release/fip.bin
+
+
+Booting Firmware Update images
+------------------------------
+
+The new images must be programmed in flash memory by adding
+an entry in the ``SITE1/HBI0262x/images.txt`` configuration file
+on the Juno SD card (where ``x`` depends on the revision of the Juno board).
+Refer to the `Juno Getting Started Guide`_, section 2.3 "Flash memory
+programming" for more information. User should ensure these do not
+overlap with any other entries in the file.
+
+::
+
+        NOR10UPDATE: AUTO                       ;Image Update:NONE/AUTO/FORCE
+        NOR10ADDRESS: 0x00400000                ;Image Flash Address [ns_bl2u_base_address]
+        NOR10FILE: \SOFTWARE\fwu_fip.bin        ;Image File Name
+        NOR10LOAD: 00000000                     ;Image Load Address
+        NOR10ENTRY: 00000000                    ;Image Entry Point
+
+        NOR11UPDATE: AUTO                       ;Image Update:NONE/AUTO/FORCE
+        NOR11ADDRESS: 0x03EB8000                ;Image Flash Address [ns_bl1u_base_address]
+        NOR11FILE: \SOFTWARE\ns_bl1u.bin        ;Image File Name
+        NOR11LOAD: 00000000                     ;Image Load Address
+
+The address ns_bl1u_base_address is the value of NS_BL1U_BASE - 0x8000000.
+In the same way, the address ns_bl2u_base_address is the value of
+NS_BL2U_BASE - 0x8000000.
+
+.. _plat_juno_booting_el3_payload:
+
+Booting an EL3 payload
+----------------------
+
+If the EL3 payload is able to execute in place, it may be programmed in flash
+memory by adding an entry in the ``SITE1/HBI0262x/images.txt`` configuration file
+on the Juno SD card (where ``x`` depends on the revision of the Juno board).
+Refer to the `Juno Getting Started Guide`_, section 2.3 "Flash memory
+programming" for more information.
+
+Alternatively, the same DS-5 command mentioned in the FVP section above can
+be used to load the EL3 payload's ELF file over JTAG on Juno.
+
+For more information on EL3 payloads in general, see
+:ref:`alt_boot_flows_el3_payload`.
+
+Booting a preloaded kernel image
+--------------------------------
+
+The Trusted Firmware must be compiled in a similar way as for FVP explained
+above. The process to load binaries to memory is the one explained in
+`plat_juno_booting_el3_payload`_.
+
+Testing System Suspend
+----------------------
+
+The SYSTEM SUSPEND is a PSCI API which can be used to implement system suspend
+to RAM. For more details refer to section 5.16 of `PSCI`_. To test system suspend
+on Juno, at the linux shell prompt, issue the following command:
+
+.. code:: shell
+
+    echo +10 > /sys/class/rtc/rtc0/wakealarm
+    echo -n mem > /sys/power/state
+
+The Juno board should suspend to RAM and then wakeup after 10 seconds due to
+wakeup interrupt from RTC.
+
+Additional Resources
+--------------------
+
+Please visit the `Arm Platforms Portal`_ to get support and obtain any other Juno
+software information. Please also refer to the `Juno Getting Started Guide`_ to
+get more detailed information about the Juno Arm development platform and how to
+configure it.
