Wolfgang,

It applies nicely to your currently published U-Boot-tree (after the refresh you did earlier today). So perhaps you could try again.

It was my fault it didn't apply earlier (the patch required that one of my other patches had been applied), I'm still learning my way around git/stgit and how things are merged.

Thanks, Magnus Lilja
