* The PMC-Sierra CIC interrupts are all centrally managed by the

* 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.
