From: Achin Gupta <achin.gu...@arm.com> The SPMC will pass the manifest to the StMM SP which contains the boot information required for SP initialisation. This patch defines the data structures defined in Section 5.4 of the FF-A v1.1 BETA0 spec to enable this support. The manifest is identified by the TF-A UUID_TOS_FW_CONFIG.
