I understand your concern, but It look very hard to maintain the new
drivers with non-dm model.

My suggestions are better to add this on existing mtd(cfi or
something) I guess ie "not possible"  or move this driver to your soc
or board code for time being till mtd uclass addition or write a fresh
mtd dm driver.

thanks!
