Thanks for re-submitting. I do have some more change requests - sorry
for being a bit strict here.

First, please change the subject to not reply on a message but also
mention the patch version in the subject (v2). And also please add
the patch history below the commit text. See here for more details
on submitting patch versions:

http://www.denx.de/wiki/view/U-Boot/Patches#Sending_updated_patch_versions

And also please change your "From:" line, so that it does not mention
"Property404" any more.

BTW: "git send-email" is very helpful for sending patches.

Thanks,
Stefan
