Hi Ed,
The string pointers in uimage_{arch,os,type,comp}[] are not being relocated and still point to flash. If flash is erased (all f's), this causes bootm to trap on a bad pointer.
This is for powerpc (mpc8572ds). How are they suppose to be relocated?

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
