* @brief 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. |
