For Arm platforms SPs are loaded by parsing tb_fw_config.dts and adding them to SP structure sequentially, which in-turn is appended to loadable image list. With recently introduced dualroot CoT for SPs where they are owned either by SiP or by Platform. SiP owned SPs index starts at SP_PKG1_ID and Plat owned SPs index starts at SP_PKG5_ID. As the start index of SP depends on the owner, there should be a mechanism to parse owner of a SP and put it at the correct index in SP structure. This patch adds support for parsing a new optional field "owner" and based on it put SP details(UUID & Load-address) at the correct index in SP structure.

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.
