It seems to me that this patch is a re-post of
http://lists.denx.de/pipermail/u-boot/2009-March/049736.html
?
If this is the case, it would be helpful if you could mark re-send patches with 'v2' or something similar, explain what changed (or what's unchanged) and that the previous patch is obsolete with the re-post.
Dirk
Btw.: A description in the body of a patch (and not subject only) going into git would be nice, too. E.g.
"Remove interrupt code which is already in xxx and therefore not needed here"
