Freescale MPIC h/w may not support all interrupt sources reported by hardware or "last-interrupt-source" or platform. On these platforms a misconfigured device tree that assigns one of the reserved interrupts leaves a non-functioning system without warning. First Patch just moves the last-irq calculation logic to a function, Second patch reworks same logic, While I feel that device-tree should get precedence over platform provided last-irq, but in this series I have not changed this logic. Third and fourth patch add non-contiguous interrupt sources support Fifth patch enables this for P2020RDB-PC for now.
