Sona Mathew d3bed15851 feat(fvp): enable errata management interface
Errata ABI feature specific build flag, flag to enable
CPUs in the cpu list, flags to test non-arm interconnect based
errata flags when enabled from a platform level.
Added to the FVP platform makefile to test the errata abi feature
implementation.

The flags to enable CPUs in the cpu list will be removed once
synchronized with the errata framework.

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.
