- * 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
