No. ROM resources really are special. They are always MMIO, and the low
bit is used to specify whether they are "enabled" or not.
Yes, it's ugly as hell. Total special case.
Anyway, the resource value of 0x00000001 shouldn't fool the if-statement
at all, because when we fill in the resource "start" values, we correctly
mask off the status bits, and save those into the resource "flags". So
the PCI resource start should be 0, and that if-statement shouldn't have
triggered.
