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