Subject: relocation: fixup cmdtable
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=620f1f6a64095ed558e68d37f1965d015cd49b02;p=u-boot.git

relocation: fixup cmdtable

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.
