In fact, that was not needed (and now causing southbridge ACPI missing) since 166c637075 (PCI: add pci_create_root_bus() that accepts resource list) and 7c090e5bfa (mips/PCI: convert to pci_scan_root_bus() for correct root bus resources) had already done the correct fix. This patch actually reverts the change made by c5de50dada. And with this fix, log says: pci 0000:00:0a.3: quirk: [io 0x1000-0x103f] claimed by PIIX4 ACPI pci 0000:00:0a.3: quirk: [io 0x1100-0x110f] claimed by PIIX4 SMB These things may not be used but as part of platform resources are better off to be included.
