Patch too large to post, see git branch for details.

ack'd. These look good. I'm just finishing up the recipe renames for linux-yocto and will start feature merging into the kernel repo shortly. I'd expect to have this in by end of day.

These are merged, and pushed. I put this in a
common location so all BSPs have the changes.

I'm doing some final build testing now, but I'll have a SRCREV update for this later today.

Cheers,

Bruce
