3 * pbm.h: PCI bus module pseudo driver software state
4 * Adopted from sparc64 by V. Roganov and G. Raiko

7 * pbm.h: U2P PCI bus module pseudo driver software state.

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.
