| * The PMC-Sierra CIC interrupts are all centrally managed by the |
| * CIC sub-system. |
| * We attempt to keep the interrupt numbers as consistent as possible |
| * across all of the MSP devices, but some differences will creep in ... |
| * The interrupts which are directly forwarded to the MIPS core interrupts |
| * are assigned interrupts in the range 0-7, interrupts cascaded through |
| * the CIC are assigned interrupts 8-39. The cascade occurs on C_IRQ4 |
| * (MSP_INT_CIC). Currently we don't really distinguish between VPE1 |
| * and VPE0 (or thread contexts for that matter). Will have to fix. |
| * The PER interrupts are assigned interrupts in the range 40-71. |
