Before adding any new SPM-related components we should first do some cleanup around the existing SPM-MM implementation. The aim is to make sure that any SPM-MM components have names that clearly indicate that they are MM-related. Otherwise, when adding new SPM code, it could quickly become confusing as it would be unclear to which component the code belongs. The secure_partition.h header is a clear example of this, as the name is generic so it could easily apply to any SPM-related code, when it is in fact SPM-MM specific. This patch renames the file and the two structures defined within it, and then modifies any references in files that use the header.

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.
