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.
