For MIPS PCI, use the resources-list style to set up root resources rather than filling in pci_bus->resource[] array directly. This will hide some ugly implementation details.
In addition, change the pci_create_bus() interface to pass in available resources to get them settled down early. This is to avoid possible resource conflicts while doing pci_scan_slot() in pci_scan_child_bus(). Note that pcibios_fixup_bus() can get rid of such conflicts, but it's done AFTER scanning slots.
Deng-Cheng Zhu (3): MIPS: PCI: Use pci_bus_remove_resources()/pci_bus_add_resource() to set up root resources PCI: Pass available resources into pci_create_bus() MIPS: PCI: Pass controller's resources to pci_create_bus() in pcibios_scanbus()
