/*
 * 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.
