NULL for root PCI busses. For busses behind a bridge, it points to a persistent copy of the bridge's pcitag_t. This can be very useful for machine-dependent PCI bus enumeration code. * Implement a machine-dependent pci_enumerate_bus() for sparc64 which uses OFW device nodes to enumerate the bus. When a PCI bus that is behind a bridge is attached, pci_attach_hook() allocates a new PCI chipset tag for the new bus and sets it's "curnode" to the OFW node of the bridge. This is used as a starting point when enumerating that bus. Root busses get the OFW node of the host bridge (psycho). * Garbage-collect "ofpci" and "ofppb" from the sparc64 port. |
