ITCM is 128K followed by 128K of DTCM. Therefore, in total, barebox PBL may not exceed 0x3f000. Now that we have a common macro for defining boards, let's add a MAX_PBL_MEMORY_SIZE_$(entrypoint) into it, so check that we don't exceed this size at runtime. Boards that trip over this, should consider using get_builtin_firmware_ext to offload binaries into barebox proper.
