Enable the SPMC to handle calls to FFA_PARTITION_INFO_GET. This allows the normal world to discover which partitions are running in the secure world including logical partitions in EL3. This implementation supports both the v1.0 and v1.1 implementations of the Partition Info Get Descriptor. The SPMC populates the appropriate descriptor in the partitions RX buffer, if requested, according to the version of FF-A that the caller is using. Additionally rename the common/uuid UUID_H include guard due to a conflict with another header file.

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.
