Detailed Description

OBIO driver.

OBIO is a short for on-board I/O. On UltraSPARC IIi and systems with U2P, there is a piece of the root PCI bus controller address space, which contains interrupt mapping and clear registers for all on-board devices. Although UltraSPARC IIi and U2P are different in general, these registers can be found at the same addresses.
