Could we also add M50FW080 to probe for also?

Some variations have either M50FW040 or M50FW080.

Hm. Since those are flash chips, I think we may want to think about GPIO
reads in flashrom instead. OTOH, GPIO read/write is not a classic
flashrom task at all.

Thoughts?

Carl-Daniel,
The only reason we need to probe these is because the IDE cable_detect 
pin is connected to a FWH GPI pin. This way we can Boot ATA100 instead 
of slow ATA33. Not sure if it is needed in flashrom, but it may make 
interesting util?

By the time flashrom could be running it's a bit late to find out
whether the connected IDE device can do UDMA :-)

So we need to find out while coreboot device init is still running. In
fact the current place might even be too late already (should be
mainboard enable, not init).

Of course you might decide to add support to dumping those GPIOs to
flashrom, but I don't really mind either way.
