Good plan. For my part, I've been factoring out more common parts
of the yocto kernel recipes, but we shouldn't be holding on those
at all. Once approved and in tree, I can actually test the factoring
on these before sending it for review, since there's nothing wrong with
having the duplication briefly.

That being said, I'm only ack'ing the series for now (and particularly
the kernel parts), since I won't be back to the office full time until
Tuesday next week to take a better look at these.

Cheers,

Bruce
