If you already have a known-good delay function with microsecond
precision, you could use that instead of waiting for flashrom to
calibrate its own delay loop.
I'd suggest a setting which makes flashrom skip all parallel flash
chips, to remove any need for calibration.
(To be more precise, the deciding factor is whether the chip is on
the local bus, or if there are some bus master(s) in between, but
that's generally equivalent to parallel vs. all others.)
