|  | *        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. |
