Yes, I know, but I thought it was okay since sunxi has never been in an
usable state, and it seemed odd to me to begin to maintain an history
for a platform that has never actually been booted by a user.

On the other end, if someone speaks up, I'd be happy to keep the old
compatible around as well.

Ah, yes, my bad.
