This commit enables trusted-firmware-a with Trusted Board Boot support for the Diphda 64-bit platform. Diphda uses a FIP image located in the flash. The FIP contains the following components: - BL2 - BL31 - BL32 - BL32 SPMC manifest - BL33 - The TBB certificates The board boot relies on CoT (chain of trust). The trusted-firmware-a BL2 is extracted from the FIP and verified by the Secure Enclave processor. BL2 verification relies on the signature area at the beginning of the BL2 image. This area is needed by the SecureEnclave bootloader. Then, the application processor is released from reset and starts by executing BL2. BL2 performs the actions described in the trusted-firmware-a TBB design document.
