[U-Boot] [PATCH/RFC v2] unify version_string

Andreas Bießmann andreas.devel at googlemail.com
Fri Jun 24 14:34:17 CEST 2011


This patch deletes the arch specific definitions of version_string in
favour of a single one in cmd_version module (which is always compiled
in).

This is an RFC as discussed in
http://article.gmane.org/gmane.comp.boot-loaders.u-boot/101695

Dear Peter Pan,

I think it would be best to base your changes to remove
timestamp on this patch (or some modified version of it)

regards

Andreas Bießmann

changes since v1:
 - remove (some) places of 'extern ... version_string' definition in favour of
   include version.h
 - use format-patch && send-email since some complained about base64 formated
   mail content
