The motivation is to support the upcoming vbootrom. The vbootrom replaces the existing BOOTMCU (RISC-V 32 SPL) flow, which currently reads the "image-bmc" from FMC_CS0 and loads the following components into DRAM: - Trusted Firmware-A - OP-TEE OS - u-boot-nodtb.bin - u-boot.dtb After loading, BOOTMCU releases the CA35 reset so that CA35 can start executing Trusted Firmware-A. The vbootrom follows the same sequence: CA35 fetches "image-bmc" from FMC0 flash at the SPI boot ROM base address (0x100000000), parses the FIT image, loads each component into its designated DRAM location, and then jumps to Trusted Firmware-A.
