Speaking with y flashrom hat on, I'd like to point out that you can use
the FT2232H Mini Module (~$30) to perform in-system-programming (well,
as long as the machine is powered of) of SPI flash chips right now and
of LPC/FWH chips in the near future. Parallel flash chips need some
small additional circuitry because the FT2232H doesn't have enough pins
for output and can only deliver 3.3V, but that's it.
