It would have been nice if subject had a 'v2' now.

Patch description missing here now. And if you re-add, it would be
good to mention that you switch from ONENAND to NAND, too.

Often it can be irritating for users if default changes silently. But
EVM people have to discuss about this, I can't say what the preferred
NAND support is.
