The current dataflash implementation really needs to be cleaned up.

It's not exactly correct that I don't care. The situation is that  we
have no such hardware in our lab. That means I cannot even test it.

The "vision" is to add  some  proper  device  interface  (similar  to
and/or  unified  with  NAND, for example). But AFAIK no such work has
been started yet.

Best regards,
