   *
   * To put things into perspective, consider sparc64 with a few PCI controllers.
   * Each type would have an own structure, with instances related one to one.
   * We have only pcic on sparc, but we want to be compatible with sparc64 pbm.h.
   * All three represent different abstractions.
   *   pci_bus  - Linux PCI subsystem view of a PCI bus (including bridged buses)
   *   pbm      - Arch-specific view of a PCI bus (sparc or sparc64)
   *   pcic     - Chip-specific information for PCIC.
