[flashrom] [PATCH] SPI read/write progress bar hack

[Carl-Daniel Hailfinger]

SPI read/write progress bar hack. Prints a dot for every page read/written.

Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006 at gmx.net>

Daniel, this patch (together with the protocol violation 3x speedup
patch) should print roughly 4 dots per second for read/erase on your
system. I suggest you only try with read to check if read time is
affected by this. If read time is unaffected, erase time will be
unaffected as well. I expect one dot every 9 seconds for write, but I
also suggest you wait with another write attempt until I get around to
posting the AAI patch for you.
