+
+ARM Trusted Firmware - version 1.3
+==================================
+
+New features
+------------
+
+* Added support for running Trusted Firmware in AArch32 execution state.
+
+ The PSCI library has been refactored to allow integration with **EL3 Runtime
+ Software**. This is software that is executing at the highest secure
+ privilege which is EL3 in AArch64 or Secure SVC/Monitor mode in AArch32. See
+ [PSCI Integration Guide].
+
+ Included is a minimal AArch32 Secure Payload, **SP-MIN**, that illustrates
+ the usage and integration of the PSCI library with EL3 Runtime Software
+ running in AArch32 state.
+
+ Booting to the BL1/BL2 images as well as booting straight to the Secure
+ Payload is supported.
+
+* Improvements to the initialization framework for the PSCI service and ARM
+ Standard Services in general.
+
+ The PSCI service is now initialized as part of ARM Standard Service
+ initialization. This consolidates the initializations of any ARM Standard
+ Service that may be added in the future.
+
+ A new function `get_arm_std_svc_args()` is introduced to get arguments
+ corresponding to each standard service and must be implemented by the EL3
+ Runtime Software.
+
+ For PSCI, a new versioned structure `psci_lib_args_t` is introduced to
+ initialize the PSCI Library. **Note** this is a compatibility break due to
+ the change in the prototype of `psci_setup()`.
+
+* To support AArch32 builds of BL1 and BL2, implemented a new, alternative
+ firmware image loading mechanism that adds flexibility.
+
+ The current mechanism has a hard-coded set of images and execution order
+ (BL31, BL32, etc). The new mechanism is data-driven by a list of image
+ descriptors provided by the platform code.
+
+ ARM platforms have been updated to support the new loading mechanism.
+
+ The new mechanism is enabled by a build flag (`LOAD_IMAGE_V2`) which is
+ currently off by default for the AArch64 build.
+
+ **Note** `TRUSTED_BOARD_BOOT` is currently not supported when
+ `LOAD_IMAGE_V2` is enabled.
+
+* Updated requirements for making contributions to ARM TF.
+
+ Commits now must have a 'Signed-off-by:' field to certify that the
+ contribution has been made under the terms of the
+ [Developer Certificate of Origin].
+
+ A signed CLA is no longer required.
+
+ The [Contribution Guide] has been updated to reflect this change.
+
+* Introduced Performance Measurement Framework (PMF) which provides support
+ for capturing, storing, dumping and retrieving time-stamps to measure the
+ execution time of critical paths in the firmware. This relies on defining
+ fixed sample points at key places in the code.
+
+* To support the QEMU platform port, imported libfdt v1.4.1 from
+ https://git.kernel.org/cgit/utils/dtc/dtc.git
+
+* Updated PSCI support:
+
+ * Added support for PSCI NODE_HW_STATE API for ARM platforms.
+
+ * New optional platform hook, `pwr_domain_pwr_down_wfi()`, in
+ `plat_psci_ops` to enable platforms to perform platform-specific actions
+ needed to enter powerdown, including the 'wfi' invocation.
+
+ * PSCI STAT residency and count functions have been added on ARM platforms
+ by using PMF.
+
+* Enhancements to the translation table library:
+
+ * Limited memory mapping support for region overlaps to only allow regions
+ to overlap that are identity mapped or have the same virtual to physical
+ address offset, and overlap completely but must not cover the same area.
+
+ This limitation will enable future enhancements without having to
+ support complex edge cases that may not be necessary.
+
+ * The initial translation lookup level is now inferred from the virtual
+ address space size. Previously, it was hard-coded.
+
+ * Added support for mapping Normal, Inner Non-cacheable, Outer
+ Non-cacheable memory in the translation table library.
+
+ This can be useful to map a non-cacheable memory region, such as a DMA
+ buffer.
+
+ * Introduced the MT_EXECUTE/MT_EXECUTE_NEVER memory mapping attributes to
+ specify the access permissions for instruction execution of a memory
+ region.
+
+* Enabled support to isolate code and read-only data on separate memory pages,
+ allowing independent access control to be applied to each.
+
+* Enabled SCR_EL3.SIF (Secure Instruction Fetch) bit in BL1 and BL31 common
+ architectural setup code, preventing fetching instructions from non-secure
+ memory when in secure state.
+
+* Enhancements to FIP support:
+
+ * Replaced `fip_create` with `fiptool` which provides a more consistent
+ and intuitive interface as well as additional support to remove an image
+ from a FIP file.
+
+ * Enabled printing the SHA256 digest with info command, allowing quick
+ verification of an image within a FIP without having to extract the
+ image and running sha256sum on it.
+
+ * Added support for unpacking the contents of an existing FIP file into
+ the working directory.
+
+ * Aligned command line options for specifying images to use same naming
+ convention as specified by TBBR and already used in cert_create tool.
+
+* Refactored the TZC-400 driver to also support memory controllers that
+ integrate TZC functionality, for example ARM CoreLink DMC-500. Also added
+ DMC-500 specific support.
+
+* Implemented generic delay timer based on the system generic counter and
+ migrated all platforms to use it.
+
+* Enhanced support for ARM platforms:
+
+ * Updated image loading support to make SCP images (SCP_BL2 and SCP_BL2U)
+ optional.
+
+ * Enhanced topology description support to allow multi-cluster topology
+ definitions.
+
+ * Added interconnect abstraction layer to help platform ports select the
+ right interconnect driver, CCI or CCN, for the platform.
+
+ * Added support to allow loading BL31 in the TZC-secured DRAM instead of
+ the default secure SRAM.
+
+ * Added support to use a System Security Control (SSC) Registers Unit
+ enabling ARM TF to be compiled to support multiple ARM platforms and
+ then select one at runtime.
+
+ * Restricted mapping of Trusted ROM in BL1 to what is actually needed by
+ BL1 rather than entire Trusted ROM region.
+
+ * Flash is now mapped as execute-never by default. This increases security
+ by restricting the executable region to what is strictly needed.
+
+* Applied following erratum workarounds for Cortex-A57: 833471, 826977,
+ 829520, 828024 and 826974.
+
+* Added support for Mediatek MT6795 platform.
+
+* Added support for QEMU virtualization ARMv8-A target.
+
+* Added support for Rockchip RK3368 and RK3399 platforms.
+
+* Added support for Xilinx Zynq UltraScale+ MPSoC platform.
+
+* Added support for ARM Cortex-A73 MPCore Processor.
+
+* Added support for ARM Cortex-A72 processor.
+
+* Added support for ARM Cortex-A35 processor.
+
+* Added support for ARM Cortex-A32 MPCore Processor.
+
+* Enabled preloaded BL33 alternative boot flow, in which BL2 does not load
+ BL33 from non-volatile storage and BL31 hands execution over to a preloaded
+ BL33. The User Guide has been updated with an example of how to use this
+ option with a bootwrapped kernel.
+
+* Added support to build ARM TF on a Windows-based host machine.
+
+* Updated Trusted Board Boot prototype implementation:
+
+ * Enabled the ability for a production ROM with TBBR enabled to boot test
+ software before a real ROTPK is deployed (e.g. manufacturing mode).
+ Added support to use ROTPK in certificate without verifying against the
+ platform value when `ROTPK_NOT_DEPLOYED` bit is set.
+
+ * Added support for non-volatile counter authentication to the
+ Authentication Module to protect against roll-back.
+
+* Updated GICv3 support:
+
+ * Enabled processor power-down and automatic power-on using GICv3.
+
+ * Enabled G1S or G0 interrupts to be configured independently.
+
+ * Changed FVP default interrupt driver to be the GICv3-only driver.
+ **Note** the default build of Trusted Firmware will not be able to boot
+ Linux kernel with GICv2 FDT blob.
+
+ * Enabled wake-up from CPU_SUSPEND to stand-by by temporarily re-routing
+ interrupts and then restoring after resume.
+
+Issues resolved since last release
+----------------------------------
+
+Known issues
+------------
+
+* The version of the AEMv8 Base FVP used in this release resets the model
+ instead of terminating its execution in response to a shutdown request using
+ the PSCI `SYSTEM_OFF` API. This issue will be fixed in a future version of
+ the model.
+
+* Building TF with compiler optimisations disabled (`-O0`) fails.
+
+
+* ARM TF cannot be built with mbed TLS version v2.3.0 due to build warnings
+ that the ARM TF build system interprets as errors.
+
+* TBBR is not currently supported when running Trusted Firmware in AArch32
+ state.

+AArch32 EL3 Runtime Software.
+
+Future changes to the entrypoint interface will be done in a backwards
+compatible way, and this enables these firmware components to be independently
+enhanced/updated to develop and exploit new functionality.
+
+#### Required CPU state when entering during cold boot
+
+This function must only be called by the primary CPU.
+
+On entry to this function the calling primary CPU must be executing in AArch32
+EL3, little-endian data access, and all interrupt sources masked:
+
+ PSTATE.AIF = 0x7
+ SCTLR.EE = 0
+
+R0 and R1 are used to pass information from the Trusted Boot Firmware to the
+platform code in AArch32 EL3 Runtime Software:
+
+ R0 : Reserved for common Trusted Firmware information
+ R1 : Platform specific information
+
+##### Use of the R0 and R1 parameters
+
+The parameters are platform specific and the convention is that `R0` conveys
+information regarding the BL3x images from the Trusted Boot firmware and `R1`
+can be used for other platform specific purpose. This convention allows
+platforms which use ARM Trusted Firmware's BL1 and BL2 images to transfer
+additional platform specific information from Secure Boot without conflicting
+with future evolution of the Trusted Firmware using `R0` to pass a `bl_params`
+structure.
+
+The AArch32 EL3 Runtime Software is responsible for entry into BL33. This
+information can be obtained in a platform defined manner, e.g. compiled into
+the AArch32 EL3 Runtime Software, or provided in a platform defined memory
+location by the Trusted Boot firmware, or passed from the Trusted Boot Firmware
+via the Cold boot Initialization parameters. This data may need to be cleaned
+out of the CPU caches if it is provided by an earlier boot stage and then
+accessed by AArch32 EL3 Runtime Software before the caches are enabled.
+
+When using AArch32 EL3 Runtime Software, the ARM development platforms pass a
+`bl_params` structure in `R0` from BL2 to be interpreted by AArch32 EL3 Runtime
+Software platform code.
+
+##### MMU, Data caches & Coherency
+
+AArch32 EL3 Runtime Software must not depend on the enabled state of the MMU,
+data caches or interconnect coherency in its entrypoint. They must be explicitly
+enabled if required.
+
+##### Data structures used in cold boot interface
+
+The AArch32 EL3 Runtime Software cold boot interface uses `bl_params` instead
+of `bl31_params`. The `bl_params` structure is based on the convention
+described in AArch64 BL31 cold boot interface section.
+
+#### Required CPU state for warm boot initialization
+
+When requesting a CPU power-on, or suspending a running CPU, AArch32 EL3
+Runtime Software must ensure execution of a warm boot initialization entrypoint.
+If ARM Trusted Firmware BL1 is used and the PROGRAMMABLE_RESET_ADDRESS build
+flag is false, then AArch32 EL3 Runtime Software must ensure that BL1 branches
+to the warm boot entrypoint by arranging for the BL1 platform function,
+plat_get_my_entrypoint(), to return a non-zero value.
+
+In this case, the warm boot entrypoint must be in AArch32 EL3, little-endian
+data access and all interrupt sources masked:
+
+ PSTATE.AIF = 0x7
+ SCTLR.EE = 0
+
+The warm boot entrypoint may be implemented by using the ARM Trusted Firmware
+`psci_warmboot_entrypoint()` function. In that case, the platform must fulfil
+the pre-requisites mentioned in the [PSCI Library integration guide]

+13. Performance Measurement Framework
+--------------------------------------
+
+The Performance Measurement Framework (PMF) facilitates collection of
+timestamps by registered services and provides interfaces to retrieve
+them from within the ARM Trusted Firmware. A platform can choose to
+expose appropriate SMCs to retrieve these collected timestamps.
+
+By default, the global physical counter is used for the timestamp
+value and is read via `CNTPCT_EL0`. The framework allows to retrieve
+timestamps captured by other CPUs.
+
+### Timestamp identifier format
+
+A PMF timestamp is uniquely identified across the system via the
+timestamp ID or `tid`. The `tid` is composed as follows:
+
+ Bits 0-7: The local timestamp identifier.
+ Bits 8-9: Reserved.
+ Bits 10-15: The service identifier.
+ Bits 16-31: Reserved.
+
+1. The service identifier. Each PMF service is identified by a
+ service name and a service identifier. Both the service name and
+ identifier are unique within the system as a whole.
+
+2. The local timestamp identifier. This identifier is unique within a given
+ service.
+
+### Registering a PMF service
+
+To register a PMF service, the `PMF_REGISTER_SERVICE()` macro from `pmf.h`
+is used. The arguments required are the service name, the service ID,
+the total number of local timestamps to be captured and a set of flags.
+
+The `flags` field can be specified as a bitwise-OR of the following values:
+
+ PMF_STORE_ENABLE: The timestamp is stored in memory for later retrieval.
+ PMF_DUMP_ENABLE: The timestamp is dumped on the serial console.
+
+The `PMF_REGISTER_SERVICE()` reserves memory to store captured
+timestamps in a PMF specific linker section at build time.
+Additionally, it defines necessary functions to capture and
+retrieve a particular timestamp for the given service at runtime.
-13. Code Structure
+The macro `PMF_REGISTER_SERVICE()` only enables capturing PMF
+timestamps from within ARM Trusted Firmware. In order to retrieve
+timestamps from outside of ARM Trusted Firmware, the
+`PMF_REGISTER_SERVICE_SMC()` macro must be used instead. This macro
+accepts the same set of arguments as the `PMF_REGISTER_SERVICE()`
+macro but additionally supports retrieving timestamps using SMCs.
+
+### Capturing a timestamp
+
+PMF timestamps are stored in a per-service timestamp region. On a
+system with multiple CPUs, each timestamp is captured and stored
+in a per-CPU cache line aligned memory region.
+
+Having registered the service, the `PMF_CAPTURE_TIMESTAMP()` macro can be
+used to capture a timestamp at the location where it is used. The macro
+takes the service name, a local timestamp identifier and a flag as arguments.
+
+The `flags` field argument can be zero, or `PMF_CACHE_MAINT` which
+instructs PMF to do cache maintenance following the capture. Cache
+maintenance is required if any of the service's timestamps are captured
+with data cache disabled.
+
+To capture a timestamp in assembly code, the caller should use
+`pmf_calc_timestamp_addr` macro (defined in `pmf_asm_macros.S`) to
+calculate the address of where the timestamp would be stored. The
+caller should then read `CNTPCT_EL0` register to obtain the timestamp
+and store it at the determined address for later retrieval.
+
+### Retrieving a timestamp
+
+From within ARM Trusted Firmware, timestamps for individual CPUs can
+be retrieved using either `PMF_GET_TIMESTAMP_BY_MPIDR()` or
+`PMF_GET_TIMESTAMP_BY_INDEX()` macros. These macros accept the CPU's MPIDR
+value, or its ordinal position, respectively.
+
+From outside ARM Trusted Firmware, timestamps for individual CPUs can be
+retrieved by calling into `pmf_smc_handler()`.
+
+ Interface : pmf_smc_handler()
+ Argument : unsigned int smc_fid, u_register_t x1,
+ u_register_t x2, u_register_t x3,
+ u_register_t x4, void *cookie,
+ void *handle, u_register_t flags
+ Return : uintptr_t
+
+ smc_fid: Holds the SMC identifier which is either `PMF_SMC_GET_TIMESTAMP_32`
+ when the caller of the SMC is running in AArch32 mode
+ or `PMF_SMC_GET_TIMESTAMP_64` when the caller is running in AArch64 mode.
+ x1: Timestamp identifier.
+ x2: The `mpidr` of the CPU for which the timestamp has to be retrieved.
+ This can be the `mpidr` of a different core to the one initiating
+ the SMC. In that case, service specific cache maintenance may be
+ required to ensure the updated copy of the timestamp is returned.
+ x3: A flags value that is either 0 or `PMF_CACHE_MAINT`. If
+ `PMF_CACHE_MAINT` is passed, then the PMF code will perform a
+ cache invalidate before reading the timestamp. This ensures
+ an updated copy is returned.
+
+The remaining arguments, `x4`, `cookie`, `handle` and `flags` are unused
+in this implementation.
+
+### PMF code structure
+
+1. `pmf_main.c` consists of core functions that implement service registration,
+ initialization, storing, dumping and retrieving timestamps.
+
+2. `pmf_smc.c` contains the SMC handling for registered PMF services.
+
+3. `pmf.h` contains the public interface to Performance Measurement Framework.

+ assembly code.
