| 4 | * Adopted from sparc64 by V. Roganov and G. Raiko |

| 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. |
