| 29 | * The PMC-Sierra CIC interrupts are all centrally managed by the |
| 30 | * CIC sub-system. |
| 31 | * We attempt to keep the interrupt numbers as consistent as possible |
| 32 | * across all of the MSP devices, but some differences will creep in ... |
| 33 | * The interrupts which are directly forwarded to the MIPS core interrupts |
| 34 | * are assigned interrupts in the range 0-7, interrupts cascaded through |
| 35 | * the CIC are assigned interrupts 8-39. The cascade occurs on C_IRQ4 |
| 36 | * (MSP_INT_CIC). Currently we don't really distinguish between VPE1 |
| 37 | * and VPE0 (or thread contexts for that matter). Will have to fix. |
| 38 | * The PER interrupts are assigned interrupts in the range 40-71. |
