The current pci_scan_root_bus() interface is made up of two main code paths: - pci_create_root_bus() - pci_scan_child_bus() pci_create_root_bus() is a wrapper function that allows to create a struct pci_host_bridge structure, initialize it with the passed parameters and register it with the kernel. As the struct pci_host_bridge require additional struct members, pci_create_root_bus() parameters list has grown in time, making it unwieldy to add further parameters to it in case the struct pci_host_bridge gains more members fields to augment its functionality. Since PCI core code provides functions to allocate struct pci_host_bridge, instead of forcing the pci_create_root_bus() interface to add new parameters to cater for new struct pci_host_bridge functionality, it is more suitable to add an interface in PCI core code to scan a PCI bus straight from a struct pci_host_bridge created and customized by each specific PCI host controller driver. Add a pci_scan_root_bus_bridge() function to allow PCI host controller drivers to create and initialize struct pci_host_bridge and scan the resulting bus.
