I beg to differ. Since we want to keep as much code as possible shared
for every flasher (SPI master), working around design bugs is more
efficient than changing flashrom to conform to every weird piece of
hardware out there.

Right now, drivers can override many SPI generic operations as needed.
If the abstraction is now powerful enough, I'm all for improving it.
Adding support for external programmers will certainly entail new
challenges.
