[flashrom] [PATCH] SPI flash chip emulator

[David Hendricks]

The patch seems very useful for testing and is benign at worst. I'd like to
see it in the tree since it greatly reduced the turnaround time for testing
partial writes and deserves some more usage. We can make it pretty later on
-- I'm already very happy to see a big mess of #defines gone from the
original patchset.

fwiw:

Minor nitpick: These should probably slice/dice the #defines from
flashchips.h.
