Subject[RFC 0/5] powerpc/mpic: Add non-contiguous interrupt sources
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.

Bharat Bhushan (5):
powerpc/mpic: move last irq logic to function
powerpc/mpic: Rework last source irq calculation logic
powerpc/mpic: Add support for non-contiguous irq ranges
powerpc/mpic: Boot print supported interrupt ranges
powerpc/fsl: Add supported-irq-ranges for P2020
