In order to move ppc-specific code out of setup_dest_addr(), provide an arch-specific variant arch_setup_dest_addr(), that can be used by architecture code to fix up the initial reloc address. It is called at the end of setup_dest_addr() initcall and the default implementation is a nop stub. Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Ovidiu Panait <ovpanait@gmail.com>
