2015-03-19arm: Add a GICv2m deviceMatt Evans
This patch adds a new PIO-accessible GICv2m shim. This shim has a PIO slave port on one side, and SPI 'wires' on the other. It accepts MSIs from the system and triggers SPIs on the GIC. It is configurable with a number of frames, each of which has a number of SPIs and a base SPI offset. A Linux driver for GICv2m is available upstream.
