 * pbm.h: PCI bus module pseudo driver software state
 *        Adopted from sparc64 by V. Roganov and G. Raiko
 * Original header:
 * pbm.h: U2P PCI bus module pseudo driver software state.
 * Copyright (C) 1997 David S. Miller (davem@caip.rutgers.edu)
 * 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.
