Re-applying Grant's change that was backed out here:
http://article.gmane.org/gmane.comp.boot-loaders.u-boot/33297 solved the
same issue (with other commands) for me when using gcc 4.2.2 for an
8572-based board. eg:
- #define CONFIG_RELOC_FIXUP_WORKS in your board header
- remove *(.fixup) from your board's linker script
- add -mrelocatable to your compile flags
Best,
Peter
