We had found one at a previous job, IIRC it was originally from
OpenBSD.  This looks very familiar:

http://www.openbsd.org/cgi-bin/cvsweb/src/sys/arch/mvme68k/dev/flash.c

but seems to be incomplete (compared to what we had).  I didn't do the
import, so I couldn't say if there's a newer version somewhere or if
we had made local changes.  I could also be confusing it with features
in the eCos driver.
