These architectures don't need relocation fixups, so reduce their codesize a bit by defining CONFIG_RELOC_FIXUP_WORKS. Also remove the reloc_off field from their global data structures as it is no longer needed. Note that the location of the standalone application jump table pointer in the global data structure is affected by this change, breaking execution of standalone applications compiled for previous versions of U-Boot. We will therefore increment XF_VERSION in the next commit, which also touches this area. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Wolfgang Denk <wd@denx.de>
