Loading Trusted-Firmware's BL31 at 16KB into DRAM was originally a hack to allow sharing more code with the other SoCs (which use this offset in SRAM). However there is no longer a reason for that, as the problematic macros have been properly separated there. The latest (and hopefully final) TF-A code drop now changes the load address to the beginning of DRAM, which is also more easily protected by the Trustzone memory controller (code to be done). Adjust the load address of BL31 now, to avoid any issues with incompatible versions later on (the TF-A patches are about to be merged).
