Ah yes, for flashing chips! Great idea!

Mh. I would prefer to probe and do something sane by default.

Of course -w is always required to actually write.

For disambiguating if there are several PCI devices that could be
used to flash I think as you say -p is a good idea.

I guess the ISA bridge is one of them too.

flashrom should list the PCI devices it sees that can be used to
flash.
