I just mean that "4bit" and "oobfirst" are independent things, so I'd
rather not have something that combines the two as part of the
configuration of the general NAND interface in the absence of a
requirement to enumerate all possibilities.  OTOH, the structure of
driver's private config can be whatever makes the most sense for that
driver, but should be named in a way that it's obviously driver-specific.
