i think we should split command line parsing from state.  the former
is clearly desirable $now.

right.  i was speaking in general.

yes & no.  i wrote up a tiny test quite that does `./u-boot ... >&
test.out`, and then compares test.out to a test.in file to make sure
things worked.  it could be made to use expect instead.

however, Marek (or maybe Jean) pointed out DUTS to me, so i stopped
working on that and switched to trying to learn that framework so we
could use what already existed rather than writing something from
scratch which i imagine Wolfgang (rightly so) would barf all over.

this is a bit ambiguous ... you want to test booting from SPI flash
and from a card in a MMC slot ?  or you want to test booting from a
card in a MMC slot connected via SPI ?
