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.
