The Neoverse reference design platforms will migrate to use different set of secure and non-secure UART ports. This implies that the board specific macros defined in the common Arm platform code will no longer be usable for Neoverse reference design platforms. In preparation for migrating to a different set of UART ports, add a Neoverse reference design platform specific copy of the board definitions. The value of these definitions will be changed in subsequent patches. Signed-off-by: Rohit Mathew <rohit.mathew@arm.com> Change-Id: I39170848ecd81a7c1bbd3689bd905e45f9435f5c |

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.
