The planes can do more than what was previously exposed. Add support for them.

Hmm, yes, that's weird. But I guess this would be part of porting it to the A20.
Also there are some more formats missing from the list, could you add them as well?
Which one do you refer to?
RGB556 and RGB655.
These formats are not supported by Linux yet though.
I see. Sorry for the noise.
