ARM: shmobile: Update romImage to relocate appended DTB
Instead of relying of MACH_TYPE for board identification, update the romImage code to relocate an appended DTB to the beginning of RAM. This implementation is independent of ARM_APPENDED_DTB, this because it is necessary to copy the DTB to memory so the kernel can access it. Without this patch Mackerel does not boot via the Mask ROM over USB (r_usb_boot) - this since non-DT boot was broken ages ago in commit: 0ce53cdc ARM: mach-shmobile: Use DT_MACHINE for mackerel Signed-off-by:Magnus Damm <damm@opensource.se> Signed-off-by:
