This patch adds an option to the ARM common platforms to load BL31 in the TZC secured DRAM instead of the default secure SRAM. To enable this feature, set `ARM_BL31_IN_DRAM` to 1 in build options. If TSP is present, then setting this option also sets the TSP location to DRAM and ignores the `ARM_TSP_RAM_LOCATION` build flag. To use this feature, BL2 platform code must map in the DRAM used by BL31. The macro ARM_MAP_BL31_SEC_DRAM is provided for this purpose. Currently, only the FVP BL2 platform code maps in this DRAM.
