rather than finding our parent pcib and using its PCI_READ_CONFIG method. - Fix the defines for the 32-bit I/O decode registers, and properly process the 16-bit versions. Now we will correctly check that I/O resources behind the bridge are going to be decoded. - Bring the quirk for the Orion PCI:PCI bridge in here (since it seems to want to set the secondary/supplementary bus numbers). - Use PCI_SLOTMAX rather than a magic number.
