Is there anything that this commit fixes, or is it just "nicer"?
If I see this correctly, then this commit would break with older
kernels, or more precisely anything that doesn't support the
"fixed-layout" compatible string, right?
For sunxi we try to keep the DTs compatible both ways, so that the
latest DT (as imported in U-Boot, for instance), can run with both
older stable and the newest kernels.

Cheers,
Andre
