Perhaps a comment here mentioning NAND as well?

So this is identical to the original 7040-db board? Perhaps its
better (or even necessary) to add a new "NAND" specific
compatible string here?

The indentation looks "fishy" above.

This empty line should probably be added before the "cpm_nand"
node.
