Sorry I'm unable to look at the patches at this time. Will do. The other
thing is Linus apparently hasn't pulled the previous portion. It has to
wait for another week+, too.

There is no rush. Also, after following the discussion about all the
"arch/arm/mach" noise and churning, I think it might be better to
combine these there boards into one file. They are quite similar to
each other. Maybe I will resubmit before too long...
Thanks in advance for your review,
Richard
