pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".
This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.
Tested on alpha and i386; welcome to 1.5Q
- cac_pci_l0 has been moved to cac.c, since it's useful for EISA boards.
- Model-specific linkage now is responsible for DMA synchronization.
- If we don't recognise the board, print the subsystem ID.
- Add support for RAID LC2 and Smart Array 431.
- Start firmware background tasks on controllers that need it.
