This patchset enhance pci_root driver to update MMCFG information when

The second patch is based on Taku Izumi work with some enhancements to
correctly handle PCI host bridges without _CBA method.
I'm sorry I won't have time to really review these for a couple weeks.
It always seemed wrong to me that we parse MCFG and set things up
before we even look at PNP0A03/PNP0A08 devices. It would make more
sense to me to have something in acpi_pci_root_add() to set up
MMCONFIG using _CBA if available, and falling back to parsing MCFG if
it's not.
I think your idea could make the code (design) much cleaner.
Do you have any other reason why you think "It always seemed
wrong..."?
