FVP: Allow BL3-2 to sit in the secure region of DRAM
This patch allows the secure payload (BL3-2) to be loaded in the DRAM region secured by the TrustZone controller (top 16 MB of DRAM1). The location of BL3-2 can be selected at build time by setting the build flag FVP_TSP_RAM_LOCATION to one of the following options: - 'tsram' : Trusted SRAM (this is the default option) - 'tdram' : Trusted DRAM - 'dram' : Secure region in DRAM1 (top 16MB configured by the TrustZone controller) The number of MMU tables in BL3-2 depends on its location in memory: 3 in case it is loaded in DRAM, 2 otherwise. Documentation updated accordingly. Fixes ARM-software/tf-issues#212 Change-Id: I371eef3a4159f06a0c9e3c6c1f4c905b2f93803a
