So looking at the code... It's an ONFI emulator.

fuword/fuiword/suword/suiword (etc) are all ancient, and I would
have expected, largely deprecated these days - but what's wrong
with copyin/copyout ?Those could be optimised for particular
data sizes if there was some real need for that.

Oh… any thoughts on “have intrsafe or not”?

can you add alignment documentation? eg, if only to say that it
must support aligned or unaligned accesses for the relevant
datatypes. not sure what we need currently, ie, if unaligned is
needed because that happens today, or we can define it as wrong
The existing fetch(9) / store(9) APIs have some problems. Specifically:
==> Their return semantics mean that fuword() cannot disambiguate between an
error condition (-1) and a legitimate fetch of -1 from user space.
==> “word” is poorly defined. For all practical purposes, it means “long”,
Do we have docs for the object nandemulator is supposed to be
emulating? Some questions have arisen about how complete it is and
nobody I've talked to seems to really have answers.
