| * @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. |
