When using the SPM Dispatcher, the SPMC sits as a BL32 component (BL32_IMAGE_ID). The SPMC manifest is passed as the TOS fw config component (TOS_FW_CONFIG_ID). It defines platform specific attributes (memory range and physical CPU layout) as well as the attributes for each secure partition (mostly load address). This manifest is passed to the SPMC on boot up. An SP package contains the SP dtb in the SPCI defined partition manifest format. As the SPMC manifest was enriched it needs an increase of tos_fw-config max-size in fvp_fw_config dts.

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.
