[U-Boot] [PATCH 13/19] omap3: remove duplicate interrupts code

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what's unchanged) and that the previous patch is obsolete with the 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"
