| * The PMC-Sierra SLP interrupts are arranged in a 3 level cascaded |
| * hierarchical system. The first level are the direct MIPS interrupts |
| * and are assigned the interrupt range 0-7. The second level is the SLM |
| * interrupt controller and is assigned the range 8-39. The third level |
| * comprises the Peripherial block, the PCI block, the PCI MSI block and |
| * the SLP. The PCI interrupts and the SLP errors are handled by the |
| * relevant subsystems so the core interrupt code needs only concern |
| * itself with the Peripheral block. These are assigned interrupts in |
| * the range 40-71. |
