- * 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.

- *
- * 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.
