This patch adds support for setting configuration of DRAM banks for FVP model in RMM-EL3 Boot Manifest structure. Structure 'rmm_manifest' is extended with 'plat_dram' structure which contains information about platform's DRAM layout: - number of DRAM banks; - pointer to 'dram_bank[]' array; - check sum: two's complement 64-bit value of the sum of data in 'plat_dram' and 'dram_bank[] array. Each 'dram_bank' structure holds information about DRAM bank base address and its size. This values must be aligned to 4KB page size. The patch increases Boot Manifest minor version to 2 and removes 'typedef rmm_manifest_t' as per "3.4.15.1. Avoid anonymous typedefs of structs/enums in headers" of https://trustedfirmware-a.readthedocs.io/en/latest/process/coding-style.html Signed-off-by: AlexeiFedorov <Alexei.Fedorov@arm.com> Change-Id: I5176caa5780e27d1e0daeb5dea3e40cf6ad5fd12
