[U-Boot] [PATCH 06/26 v2][NEXT] relocation: fixup cmdtable

Heiko Schocher
2010-09-17T11:10:33Z

fixup_cmdtable() did all work for fixing up the cmdtable,
if CONFIG_RELOC_FIXUP_WORKS is not defined.

CONFIG_RELOC_FIXUP_WORKS is missing for i386! I talked
with Graeme Russ, and he will fix this soon.

Portions of this work were supported by funding from
the CE Linux Forum.
