| * 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. | |
