Reported the status (applies, missing) of AT speculative workaround which is applicable for below CPUs. +---------+--------------+ | Errata | CPU | +=========+==============+ | 1165522 | Cortex-A76 | +---------+--------------+ | 1319367 | Cortex-A72 | +---------+--------------+ | 1319537 | Cortex-A57 | +---------+--------------+ | 1530923 | Cortex-A55 | +---------+--------------+ | 1530924 | Cortex-A53 | +---------+--------------+ Also, changes are done to enable common macro 'ERRATA_SPECULATIVE_AT' if AT speculative errata workaround is enabled for any of the above CPUs using 'ERRATA_*' CPU specific build macro.

Trusted Firmware-A
Trusted Firmware-A (TF-A) is a reference implementation of secure world software for Arm A-Profile architectures (Armv8-A and Armv7-A), including an Exception Level 3 (EL3) Secure Monitor. It provides a suitable starting point for productization of secure world boot and runtime firmware, in either the AArch32 or AArch64 execution states.
TF-A implements Arm interface standards, including:
- Power State Coordination Interface (PSCI)
- Trusted Board Boot Requirements CLIENT (TBBR-CLIENT)
- SMC Calling Convention
- System Control and Management Interface (SCMI)
- Software Delegated Exception Interface (SDEI)
The code is designed to be portable and reusable across hardware platforms and software models that are based on the Armv8-A and Armv7-A architectures.
In collaboration with interested parties, we will continue to enhance TF-A with reference implementations of Arm standards to benefit developers working with Armv7-A and Armv8-A TrustZone technology.
Users are encouraged to do their own security validation, including penetration testing, on any secure world code derived from TF-A.
