 OK, I'll add that info to the commit message when applying. Or if you could
resubmit with an updated commit message, that would be great.

 Improving the readme.txt to directly explain how to update U-Boot would indeed
be great. It's best to keep both the "upstream" reference (which will not be
Buildroot-specific), and a short step-by-step explanation of how to do it with
the Buildroot output.

 Note that an update of the readme.txt should of course be a separate patch from
the U-Boot + kernel bump.

 Arnout
