To build and execute OP-TEE follow the instructions at
`OP-TEE build.git`_
+There are two different modes for loading the OP-TEE OS. The default mode will
+load it as the BL32 payload during boot, and is the recommended technique for
+platforms to use. There is also another technique that will load OP-TEE OS after
+boot via an SMC call by enabling the option for OPTEE_ALLOW_SMC_LOAD that was
+specifically added for ChromeOS. Loading OP-TEE via an SMC call may be insecure
+depending upon the platform configuration. If using that option, be sure to
+understand the risks involved with allowing the Trusted OS to be loaded this
+way. ChromeOS uses a boot flow where it verifies the signature of the firmware
+before executing it, and then only if the signature is valid will the 'secrets'
+used by the TEE become accessible. The firmware then verifies the signature of
+the kernel using depthcharge, and the kernel verifies the rootfs using
+dm-verity. The SMC call to load OP-TEE is then invoked immediately after the
+kernel finishes loading and before any attack vectors can be opened up by
+mounting writable filesystems or opening network/device connections. this
+ensures the platform is 'closed' and running signed code through the point where
+OP-TEE is loaded.

+Introduction
+------------
+
+Power state coordination
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+A power domain topology is a logical hierarchy of power domains in a system that
+arises from the physical dependencies between power domains.
+
+Local power states describe power states for an individual node, and composite
+power states describe the combined power states for an individual node and its
+parent node(s).
+
+Entry into low-power states for a topology node above the core level requires
+coordinating its children nodes. For example, in a system with a power domain
+that encompasses a shared cache, and a separate power domain for each core that
+uses the shared cache, the core power domains must be powered down before the
+shared cache power domain can be powered down.
+
+PSCI supports two modes of power state coordination: platform-coordinated and
+OS-initiated.
+
+Platform-coordinated
+~~~~~~~~~~~~~~~~~~~~
+
+Platform-coordinated mode is the default mode of power state coordination, and
+is currently the only supported mode in TF-A.
+
+In platform-coordinated mode, the platform is responsible for coordinating power
+states, and chooses the deepest power state for a topology node that can be
+tolerated by its children.
+
+OS-initiated
+~~~~~~~~~~~~
+
+OS-initiated mode is optional.
+
+In OS-initiated mode, the calling OS is responsible for coordinating power
+states, and may request for a topology node to enter a low-power state when
+its last child enters the low-power state.
+
+Motivation
+----------
+
+There are two reasons why OS-initiated mode might be a more suitable option than
+platform-coordinated mode for a platform.
+
+Scalability
+^^^^^^^^^^^
+
+In platform-coordinated mode, each core independently selects their own local
+power states, and doesn't account for composite power states that are shared
+between cores.
+
+In OS-initiated mode, the OS has knowledge of the next wakeup event for each
+core, and can have more precise control over the entry, exit, and wakeup
+latencies when deciding if a composite power state (e.g. for a cluster) is
+appropriate. This is especially important for multi-cluster SMP systems and
+heterogeneous systems like big.LITTLE, where different processor types can have
+different power efficiencies.
+
+Simplicity
+^^^^^^^^^^
+
+In platform-coordinated mode, the OS doesn't have visibility when the last core
+at a power level enters a low-power state. If the OS wants to perform last man
+activity (e.g. powering off a shared resource when it is no longer needed), it
+would have to communicate with an API side channel to know when it can do so.
+This could result in a design smell where the platform is using
+platform-coordinated mode when it should be using OS-initiated mode instead.
+
+In OS-initiated mode, the OS can perform last man activity if it selects a
+composite power state when the last core enters a low-power state. This
+eliminates the need for a side channel, and uses the well documented API between
+the OS and the platform.
+
+Current vendor implementations and workarounds
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+* STMicroelectronics
+
+ * For their ARM32 platforms, they're using OS-initiated mode implemented in
+ OP-TEE.
+ * For their future ARM64 platforms, they are interested in using OS-initiated
+ mode in TF-A.
+
+* Qualcomm
+
+ * For their mobile platforms, they're using OS-initiated mode implemented in
+ their own custom secure monitor firmware.
+ * For their Chrome OS platforms, they're using platform-coordinated mode in
+ TF-A with custom driver logic to perform last man activity.
+
+* Google
+
+ * They're using platform-coordinated mode in TF-A with custom driver logic to
+ perform last man activity.
+
+Both Qualcomm and Google would like to be able to use OS-initiated mode in TF-A
+in order to simplify custom driver logic.

+
+PSCI_SET_SUSPEND_MODE
+^^^^^^^^^^^^^^^^^^^^^
+
+PSCI_SET_SUSPEND_MODE is for switching between the two different modes of power
+state coordination.
+
+.. c:macro:: PSCI_SET_SUSPEND_MODE
+
+ :param func_id: 0x8400_000F.
+ :param mode: 0 indicates platform-coordinated mode, 1 indicates OS-initiated

+ :retval SUCCESS: if the request is successful.
+ :retval NOT_SUPPORTED: if OS-initiated mode is not supported.
+ :retval INVALID_PARAMETERS: if the requested mode is not a valid value (0 or
+ 1).
+ :retval DENIED: if the cores are not in the correct state.
+
+Switching from platform-coordinated to OS-initiated is only allowed if the
+following conditions are met:
+
+* All cores are in one of the following states:
+
+ * Running.
+ * Off, through a call to CPU_OFF or not yet booted.
+ * Suspended, through a call to CPU_DEFAULT_SUSPEND.
+
+* None of the cores has called CPU_SUSPEND since the last change of mode or
+ boot.
+
+Switching from OS-initiated to platform-coordinated is only allowed if all cores
+other than the calling core are off, either through a call to CPU_OFF or not yet
+booted.
+
+If these conditions are not met, the PSCI implementation must return DENIED.
+
+See sections 5.1.19 and 5.20 of the PSCI spec (DEN0022D.b) for more details.
+
+CPU_SUSPEND
+^^^^^^^^^^^
+
+CPU_SUSPEND is for moving a topology node into a low-power state.
+
+.. c:macro:: CPU_SUSPEND
+
+ :param func_id: 0xC400_0001.
+ :param power_state: the requested low-power state to enter.
+ :param entry_point_address: the address at which the core must resume
+ execution following wakeup from a powerdown state.
+ :param context_id: this field specifies a pointer to the saved context that
+ must be restored on a core following wakeup from a powerdown state.
+ :retval SUCCESS: if the request is successful.
+ :retval INVALID_PARAMETERS: in OS-initiated mode, this error is returned when
+ a low-power state is requested for a topology node above the core level,
+ and at least one of the node's children is in a local low-power state
+ that is incompatible with the request.
+ :retval INVALID_ADDRESS: if the entry_point_address argument is invalid.
+ :retval DENIED: only in OS-initiated mode; this error is returned when a
+ low-power state is requested for a topology node above the core level,
+ and at least one of the node's children is running, i.e. not in a
+ low-power state.
+
+In platform-coordinated mode, the PSCI implementation coordinates requests from
+all cores to determine the deepest power state to enter.
+
+In OS-initiated mode, the calling OS is making an explicit request for a
+specific power state, as opposed to expressing a vote. The PSCI implementation
+must comply with the request, unless the request is not consistent with the
+implementation's view of the system's state, in which case, the implementation
+must return INVALID_PARAMETERS or DENIED.
+
+See sections 5.1.2 and 5.4 of the PSCI spec (DEN0022D.b) for more details.
+
+Power state formats
+~~~~~~~~~~~~~~~~~~~
+
+Original format
+
+* Power Level, bits[25:24]
+
+ * The requested level in the power domain topology to enter a low-power
+ state.
+
+* State Type, bit[16]
+
+ * A value of 0 indicates a standby or retention state.
+ * A value of 1 indicates a powerdown state.
+
+* State ID, bits[15:0]
+
+ * Field to specify the requested composite power state.
+ * The state ID encodings must uniquely describe every possible composite
+ power state.
+ * In OS-initiated mode, the state ID encoding must allow expressing the
+ power level at which the calling core is the last to enter a powerdown
+ state.
+
+Extended format
+
+* State Type, bit[30]
+* State ID, bits[27:0]
+
+Races in OS-initiated mode
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In OS-initiated mode, there are race windows where the OS's view and
+implementation's view of the system's state differ. It is possible for the OS to
+make requests that are invalid given the implementation's view of the system's
+state. For example, the OS might request a powerdown state for a node from one
+core, while at the same time, the implementation observes that another core in
+that node is powering up.
+
+To address potential race conditions in power state requests:
+
+* The calling OS must specify in each CPU_SUSPEND request the deepest power
+ level for which it sees the calling core as the last running core (last man).
+ This is required even if the OS doesn't want the node at that power level to
+ enter a low-power state.
+* The implementation must validate that the requested power states in the
+ CPU_SUSPEND request are consistent with the system's state, and that the
+ calling core is the last core running at the requested power level, or deny
+ the request otherwise.
+
+See sections 4.2.3.2, 6.2, and 6.3 of the PSCI spec (DEN0022D.b) for more
+details.
+
+Caveats
+-------
+
+CPU_OFF
+^^^^^^^
+
+CPU_OFF is always platform-coordinated, regardless of whether the power state
+coordination mode for suspend is platform-coordinated or OS-initiated. If all
+cores in a topology node call CPU_OFF, the last core will power down the node.
+
+In OS-initiated mode, if a subset of the cores in a topology node has called
+CPU_OFF, the last running core may call CPU_SUSPEND to request a powerdown state
+at or above that node's power level.
+
+See section 5.5.2 of the PSCI spec (DEN0022D.b) for more details.
+
+Implementation
+--------------
+
+Current implementation of platform-coordinated mode
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Platform-coordinated is currently the only supported power state coordination
+mode in TF-A.
+
+The functions of interest in the ``psci_cpu_suspend`` call stack are as follows:
+
+* ``psci_validate_power_state``
+
+ * This function calls a platform specific ``validate_power_state`` handler,
+ which takes the ``power_state`` parameter, and updates the ``state_info``
+ object with the requested states for each power level.
+
+* ``psci_find_target_suspend_lvl``
+
+ * This function takes the ``state_info`` object containing the requested power
+ states for each power level, and returns the deepest power level that was
+ requested to enter a low power state, i.e. the target power level.
+
+* ``psci_do_state_coordination``
+
+ * This function takes the target power level and the ``state_info`` object
+ containing the requested power states for each power level, and updates the
+ ``state_info`` object with the coordinated target power state for each
+ level.
+
+* ``pwr_domain_suspend``
+
+ * This is a platform specific handler that takes the ``state_info`` object
+ containing the target power states for each power level, and transitions
+ each power level to the specified power state.
+
+Proposed implementation of OS-initiated mode
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To add support for OS-initiated mode, the following changes are proposed:
+
+* Add a boolean build option ``PSCI_OS_INIT_MODE`` for a platform to enable
+ optional support for PSCI OS-initiated mode. This build option defaults to 0.
+
+.. note::
+
+ If ``PSCI_OS_INIT_MODE=0``, the following changes will not be compiled into
+ the build.
+
+* Update ``psci_features`` to return 1 in bit[0] to indicate support for
+ OS-initiated mode for CPU_SUSPEND.
+* Define a ``suspend_mode`` enum: ``PLAT_COORD`` and ``OS_INIT``.
+* Define a ``psci_suspend_mode`` global variable with a default value of
+ ``PLAT_COORD``.
+* Implement a new function handler ``psci_set_suspend_mode`` for
+ PSCI_SET_SUSPEND_MODE.
+* Since ``psci_validate_power_state`` calls a platform specific
+ ``validate_power_state`` handler, the platform implementation should populate
+ the ``state_info`` object based on the state ID from the given ``power_state``
+ parameter.
+* ``psci_find_target_suspend_lvl`` remains unchanged.
+* Implement a new function ``psci_validate_state_coordination`` that ensures the
+ request satisfies the following conditions, and denies any requests
+ that don't:
+
+ * The requested power states for each power level are consistent with the
+ system's state
+ * The calling core is the last core running at the requested power level
+
+ This function differs from ``psci_do_state_coordination`` in that:
+
+ * The ``psci_req_local_pwr_states`` map is not modified if the request were to
+ be denied
+ * The ``state_info`` argument is never modified since it contains the power
+ states requested by the calling OS
+
+* Update ``psci_cpu_suspend_start`` to do the following:
+
+ * If ``PSCI_SUSPEND_MODE`` is ``PLAT_COORD``, call
+ ``psci_do_state_coordination``.
+ * If ``PSCI_SUSPEND_MODE`` is ``OS_INIT``, call
+ ``psci_validate_state_coordination``. If validation fails, propagate the
+ error up the call stack.
+
+* Update the return type of the platform specific ``pwr_domain_suspend``
+ handler from ``void`` to ``int``, to allow the platform to optionally perform
+ validations based on hardware states.

+Runtime Security Subsystem (RSS)
+================================
+
+This document focuses on the relationship between the Runtime Security Subsystem
+(RSS) and the application processor (AP). According to the ARM reference design
+the RSS is an independent core next to the AP and the SCP on the same die. It
+provides fundamental security guarantees and runtime services for the rest of
+the system (e.g.: trusted boot, measured boot, platform attestation,
+key management, and key derivation).
+
+At power up RSS boots first from its private ROM code. It validates and loads
+its own images and the initial images of SCP and AP. When AP and SCP are
+released from reset and their initial code is loaded then they continue their
+own boot process, which is the same as on non-RSS systems. Please refer to the
+``RSS documentation`` [1]_ for more details about the RSS boot flow.
+
+The last stage of the RSS firmware is a persistent, runtime component. Much
+like AP_BL31, this is a passive entity which has no periodical task to do and
+just waits for external requests from other subsystems. RSS and other
+subsystems can communicate with each other over message exchange. RSS waits
+in idle for the incoming request, handles them, and sends a response then goes
+back to idle.
+
+RSS communication layer
+-----------------------
+
+The communication between RSS and other subsystems are primarily relying on the
+Message Handling Unit (MHU) module. The number of MHU interfaces between RSS
+and other cores is IMPDEF. Besides MHU other modules also could take part in
+the communication. RSS is capable of mapping the AP memory to its address space.
+Thereby either RSS core itself or a DMA engine if it is present, can move the
+data between memory belonging to RSS or AP. In this way, a bigger amount of data
+can be transferred in a short time.
+
+The MHU comes in pairs. There is a sender and receiver side. They are connected
+to each other. An MHU interface consists of two pairs of MHUs, one sender and
+one receiver on both sides. Bidirectional communication is possible over an
+interface. One pair provides message sending from AP to RSS and the other pair
+from RSS to AP. The sender and receiver are connected via channels. There is an
+IMPDEF number of channels (e.g: 4-16) between a sender and a receiver module.
+
+The RSS communication layer provides two ways for message exchange:
+
+- ``Embedded messaging``: The full message, including header and payload, are
+ exchanged over the MHU channels. A channel is capable of delivering a single
+ word. The sender writes the data to the channel register on its side and the
+ receiver can read the data from the channel on the other side. One dedicated
+ channel is used for signalling. It does not deliver any payload it is just
+ meant for signalling that the sender loaded the data to the channel registers
+ so the receiver can read them. The receiver uses the same channel to signal
+ that data was read. Signalling happens via IRQ. If the message is longer than
+ the data fit to the channel registers then the message is sent over in
+ multiple rounds. Both, sender and receiver allocate a local buffer for the
+ messages. Data is copied from/to these buffers to/from the channel registers.
+- ``Pointer-access messaging``: The message header and the payload are
+ separated and they are conveyed in different ways. The header is sent
+ over the channels, similar to the embedded messaging but the payload is
+ copied over by RSS core (or by DMA) between the sender and the receiver. This
+ could be useful in the case of long messages because transaction time is less
+ compared to the embedded messaging mode. Small payloads are copied by the RSS
+ core because setting up DMA would require more CPU cycles. The payload is
+ either copied into an internal buffer or directly read-written by RSS. Actual
+ behavior depends on RSS setup, whether the partition supports memory-mapped
+ ``iovec``. Therefore, the sender must handle both cases and prevent access to
+ the memory, where payload data lives, while the RSS handles the request.
+
+The RSS communication layer supports both ways of messaging in parallel. It is
+decided at runtime based on the message size which way to transfer the message.

+
+Message structure
+^^^^^^^^^^^^^^^^^
+A description of the message format can be found in the ``RSS communication
+design`` [2]_ document.
+
+Source files
+^^^^^^^^^^^^
+- RSS comms: ``drivers/arm/rss``
+- MHU driver: ``drivers/arm/mhu``
+
+
+API for communication over MHU
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+The API is defined in these header files:
+
+- ``include/drivers/arm/rss_comms.h``
+- ``include/drivers/arm/mhu.h``
+
+RSS provided runtime services
+-----------------------------
+
+RSS provides the following runtime services:
+
+- ``Measured boot``: Securely store the firmware measurements which were
+ computed during the boot process and the associated metadata (image
+ description, measurement algorithm, etc.). More info on measured boot service
+ in RSS can be found in the ``measured_boot_integration_guide`` [3]_ .
+- ``Delegated attestation``: Query the platform attestation token and derive a
+ delegated attestation key. More info on the delegated attestation service
+ in RSS can be found in the ``delegated_attestation_integration_guide`` [4]_ .
+- ``OTP assets management``: RSS provides access for AP to assets in OTP.
+ These are keys for image signature verification and non-volatile counters
+ for anti-rollback protection. Only RSS has direct access to the OTP. Public
+ keys used by AP during the trusted boot process can be requested from RSS.
+ Furthermore, AP can request RSS to increase a non-volatile counter. Please
+ refer to the ``RSS key management`` [5]_ document for more details.
+
+Runtime service API
+^^^^^^^^^^^^^^^^^^^
+The RSS provided runtime services implement a PSA aligned API. The parameter
+encoding follows the PSA client protocol described in the
+``Firmware Framework for M`` [6]_ document in chapter 4.4. The implementation is
+restricted to the static handle use case therefore only the ``psa_call`` API is
+implemented.

+RSS based Measured Boot
+-----------------------
+
+Measured Boot is the process of cryptographically measuring (computing the hash
+value of a binary) the code and critical data used at boot time. The
+measurement must be stored in a tamper-resistant way, so the security state
+of the device can be attested later to an external party. RSS provides a runtime
+service which is meant to store measurements and associated metadata alongside.
+
+Data is stored in internal SRAM which is only accessible by the secure runtime
+firmware of RSS. Data is stored in so-called measurement slots. A platform has
+IMPDEF number of measurement slots. The measurement storage follows extend
+semantics. This means that measurements are not stored directly (as it was
+taken) instead they contribute to the current value of the measurement slot.
+The extension implements this logic, where ``||`` stands for concatenation:
+
+.. code-block:: bash
+
+ new_value_of_measurement_slot = Hash(old_value_of_measurement_slot || measurement)
+
+Supported hash algorithms: sha-256, sha-512
+
+Measured Boot API
+^^^^^^^^^^^^^^^^^
+
+Defined here:
+
+- ``include/lib/psa/measured_boot.h``
+
+.. code-block:: c
+
+ psa_status_t
+ rss_measured_boot_extend_measurement(uint8_t index,
+ const uint8_t *signer_id,
+ size_t signer_id_size,
+ const uint8_t *version,
+ size_t version_size,
+ uint32_t measurement_algo,
+ const uint8_t *sw_type,
+ size_t sw_type_size,
+ const uint8_t *measurement_value,
+ size_t measurement_value_size,
+ bool lock_measurement);
+
+Measured Boot Metadata
+^^^^^^^^^^^^^^^^^^^^^^
+
+The following metadata can be stored alongside the measurement:
+
+- ``Signer-id``: Mandatory. The hash of the firmware image signing public key.
+- ``Measurement algorithm``: Optional. The hash algorithm which was used to
+ compute the measurement (e.g.: sha-256, etc.).
+- ``Version info``: Optional. The firmware version info (e.g.: 2.7).
+- ``SW type``: Optional. Short text description (e.g.: BL1, BL2, BL31, etc.)
+
+.. Note::
+ Signer-id and version info is not implemented in TF-A yet.
+
+The caller must specify in which measurement slot to extend a certain
+measurement and metadata. A measurement slot can be extended by multiple
+measurements. The default value is IMPDEF. All measurement slot is cleared at
+reset, there is no other way to clear them. In the reference implementation,
+the measurement slots are initialized to 0. At the first call to extend the
+measurement in a slot, the extend operation uses the default value of the
+measurement slot. All upcoming extend operation on the same slot contributes
+to the previous value of that measurement slot.
+
+The following rules are kept when a slot is extended multiple times:
+
+- ``Signer-id`` must be the same as the previous call(s), otherwise a
+ PSA_ERROR_NOT_PERMITTED error code is returned.
+
+- ``Measurement algorithm``: must be the same as the previous call(s),
+ otherwise, a PSA_ERROR_NOT_PERMITTED error code is returned.
+
+In case of error no further action is taken (slot is not locked). If there is
+a valid data in a sub-sequent call then measurement slot will be extended. The
+rest of the metadata is handled as follows when a measurement slot is extended
+multiple times:
+
+- ``SW type``: Cleared.
+- ``Version info``: Cleared.
+
+.. Note::
+
+ Extending multiple measurements in the same slot leads to some metadata
+ information loss. Since RSS is not constrained on special HW resources to
+ store the measurements and metadata, therefore it is worth considering to
+ store all of them one by one in distinct slots. However, they are one-by-one
+ included in the platform attestation token. So, the number of distinct
+ firmware image measurements has an impact on the size of the attestation
+ token.
+
+The allocation of the measurement slot among RSS, Root and Realm worlds is
+platform dependent. The platform must provide an allocation of the measurement
+slot at build time. An example can be found in
+``tf-a/plat/arm/board/tc/tc_bl1_measured_boot.c``
+Furthermore, the memory, which holds the metadata is also statically allocated
+in RSS memory. Some of the fields have a static value (measurement algorithm),
+and some of the values have a dynamic value (measurement value) which is updated
+by the bootloaders when the firmware image is loaded and measured. The metadata
+structure is defined in
+``include/drivers/measured_boot/rss/rss_measured_boot.h``.
+
+.. code-block:: c
+
+ struct rss_mboot_metadata {
+ unsigned int id;
+ uint8_t slot;
+ uint8_t signer_id[SIGNER_ID_MAX_SIZE];
+ size_t signer_id_size;
+ uint8_t version[VERSION_MAX_SIZE];
+ size_t version_size;
+ uint8_t sw_type[SW_TYPE_MAX_SIZE];
+ size_t sw_type_size;
+ bool lock_measurement;
+ };
+
+Build time config options
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- ``MEASURED_BOOT``: Enable measured boot. It depends on the platform
+ implementation whether RSS or TPM (or both) backend based measured boot is
+ enabled.
+- ``MBOOT_RSS_HASH_ALG``: Determine the hash algorithm to measure the images.
+ The default value is sha-256.

+Delegated Attestation
+---------------------
+
+Delegated Attestation Service was mainly developed to support the attestation
+flow on the ``ARM Confidential Compute Architecture`` (ARM CCA) [7]_.
+The detailed description of the delegated attestation service can be found in
+the ``Delegated Attestation Service Integration Guide`` [4]_ document.
+
+In the CCA use case, the Realm Management Monitor (RMM) relies on the delegated
+attestation service of the RSS to get a realm attestation key and the CCA
+platform token. BL31 does not use the service for its own purpose, only calls
+it on behalf of RMM. The access to MHU interface and thereby to RSS is
+restricted to BL31 only. Therefore, RMM does not have direct access, all calls
+need to go through BL31. The RMM dispatcher module of the BL31 is responsible
+for delivering the calls between the two parties.
+
+.. Note::
+ Currently the connection between the RMM dispatcher and the PSA/RSS layer
+ is not yet implemented. RMM dispatcher just returns hard coded data.

+Booting via flash based firmware
+--------------------------------
-Boot firmwares are loaded via secure FLASH0 device so ``bl1.bin`` and
-``fip.bin`` should be concatenated to create a ``flash.bin`` that is flashed
-onto secure FLASH0.
+An alternate approach to deploy a full system stack on QEMU is to load the
+firmware via a secure flash device. This involves concatenating ``bl1.bin`` and
+``fip.bin`` to create a boot ROM that is flashed onto secure FLASH0 with the
+``-bios`` option.
-- ``bl32.bin`` -> BL32 (``tee-header_v2.bin``)
-- ``bl32_extra1.bin`` -> BL32 Extra1 (``tee-pager_v2.bin``)
-- ``bl32_extra2.bin`` -> BL32 Extra2 (``tee-pageable_v2.bin``)
-- ``bl33.bin`` -> BL33 (``QEMU_EFI.fd``)
+For example, to test the following firmware stack:
+
+
+- BL32 - ``bl32.bin`` -> ``tee-header_v2.bin``
+- BL32 Extra1 - ``bl32_extra1.bin`` -> ``tee-pager_v2.bin``

+"reset". In addition to this, it places the information about the kernel
+provided with option ``-kernel``, and the RamDisk provided with ``-initrd``,
+into the firmware configuration ``fw_cfg``. In this setup, EDK II is responsible
+for extracting and launching these from ``fw_cfg``.
+
+.. note::
+ QEMU may be launched with or without ACPI (``-acpi``/``-no-acpi``). In
+ either case, ensure that the kernel build options are aligned with the

+ZynqMP Debug behavior
+---------------------
+
+With DEBUG=1, TF-A for ZynqMP uses DDR memory range instead of OCM memory range
+due to size constraints.
+For DEBUG=1 configuration for ZynqMP the BL31_BASE is set to the DDR location
+of 0x1000 and BL31_LIMIT is set to DDR location of 0x7FFFF. By default the
+above memory range will NOT be reserved in device tree.
+
+To reserve the above memory range in device tree, the device tree base address
+must be provided during build as,
+
+make CROSS_COMPILE=aarch64-none-elf- PLAT=zynqmp RESET_TO_BL31=1 DEBUG=1 \
+ XILINX_OF_BOARD_DTB_ADDR=<DTB address> bl31
+
+The default DTB base address for ZynqMP platform is 0x100000. This default value
+is not set in the code and to use this default address, user still needs to
+provide it through the build command as above.
+
+If the user wants to move the bl31 to a different DDR location, user can provide
+the DDR address location using the build time parameters ZYNQMP_ATF_MEM_BASE and
+ZYNQMP_ATF_MEM_SIZE.
+
+The DDR address must be reserved in the DTB by the user, either by manually
+adding the reserved memory node, in the device tree, with the required address
+range OR let TF-A modify the device tree on the run.
+
+To let TF-A access and modify the device tree, the DTB address must be provided
+to the build command as follows,
+
+make CROSS_COMPILE=aarch64-none-elf- PLAT=zynqmp RESET_TO_BL31=1 DEBUG=1 \
+ ZYNQMP_ATF_MEM_BASE=<DDR address> ZYNQMP_ATF_MEM_SIZE=<size> \
+ XILINX_OF_BOARD_DTB_ADDR=<DTB address> bl31
+
+DDR Address Range Usage
+-----------------------
+
+When FSBL runs on RPU and TF-A is to be placed in DDR address range,
+then the user needs to make sure that the DDR address is beyond 256KB.
+In the RPU view, the first 256 KB is TCM memory.
+
+For this use case, with the minimum base address in DDR for TF-A,
+the build command example is;
+
+make CROSS_COMPILE=aarch64-none-elf- PLAT=zynqmp RESET_TO_BL31=1 DEBUG=1 \

- Low-level code where specific system-level instructions must be used, such
as cache maintenance operations.
+Do not use weak functions
+-------------------------
+
+.. note::
+
+ The following guideline applies more strongly to common, platform-independent
+ code. For plaform code (under ``plat/`` directory), it is up to each platform
+ maintainer to decide whether this should be striclty enforced or not.
+
+The use of weak functions is highly discouraged in the TF-A codebase. Newly
+introduced platform interfaces should be strongly defined, wherever possible. In
+the rare cases where this is not possible or where weak functions appear as the
+best tool to solve the problem at hand, this should be discussed with the
+project's maintainers and justified in the code.
+
+For the purpose of providing a default implementation of a platform interface,
+an alternative to weak functions is to provide a strongly-defined implementation
+under the ``plat/common/`` directory. Then platforms have two options to pull
+in this implementation:
+
+ - They can include the source file through the platform's makefile. Note that
+ this method is suitable only if the platform wants *all* default
+ implementations defined in this file, else either the file should be
+ refactored or the next approach should be used.
+
+ - They access the platform interface through a **constant** function pointer.
+
+In both cases, what matters is that platforms include the default implementation
+as a conscious decision.
+
+.. rubric:: Rationale
+
+Weak functions may sound useful to simplify the initial porting effort to a
+new platform, such that one can quickly get the firmware to build and link,
+without implementing all platform interfaces from the beginning. For this
+reason, the TF-A project used to make heavy use of weak functions and there
+are still many outstanding usages of them across the code base today. We
+intend to convert them to strongly-defined functions over time.
+
+However, weak functions also have major drawbacks, which we consider
+outweighing their benefits. They can make it hard to identify which
+implementation gets built into the firmware, especially when using multiple
+levels of "weakness". This has resulted in bugs in the past.
+
+Weak functions are also forbidden by MISRA coding guidelines, which TF-A aims to
+comply with.

+| Threat | | **Attacker wants to execute an arbitrary or |

+| | BL32 payload. If a compromise occurs before the |
