does the spi flash patch you posted satisfy your first part here ?
after all, the back end shouldn't matter so long as "sf" is able to
read data out of a file into memory.
otherwise, i'll try and update the spi flash patch i posted sooner
rather than later.

as for sd/mmc, i think you might be on your own there.  i only have a
passing familiarity with the spec and would have to do quite a bit of
reading/learning first.  which i'm not terribly interested in doing at
this time i'm sorry to say.  the patents/licensing the sd peeps have
in place make that storage medium decidedly less interesting to me,
although i might suck it up (much further down the line) considering
it seems to (sadly) be the foreseeable future of storage in embedded.
