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

* Adopted from sparc64 by V. Roganov and G. Raiko

*
|
|
* 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.
