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