This patch adds support for Firmware update in BL2U for ARM platforms such that TZC initialization is performed on all ARM platforms and (optionally) transfer of SCP_BL2U image on ARM CSS platforms. BL2U specific functions are added to handle early_platform and plat_arch setup. The MMU is configured to map in the BL2U code/data area and other required memory.
