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.
