If there are people who have the boards, I'd be inclined to make the
mainline kernel usable for them. Doing some renames or adding
compatibles down the road, if the SoC is actually rebranded, is not a big
deal. I'll leave it up to you guys as to what to do - it's only -rc4
today, so there's no impending doom.

Cheers,
