Some arches use different names, e.g., pci_sys_data, pci_hba_data, pci_channel, etc. When I added support in the PCI core for host bridge address translation, e.g., ACPI _TRA, I named the core structure pci_host_bridge. Some of the stuff in pci_controller and similar arch-dependent structures could probably be moved into pci_host_bridge, given appropriate PCI core interfaces to supply the information (or maybe pcibios_*() functions the core could use to retrieve it). But I doubt we could completely remove the arch-dependent structures.
