Arm Generic Interrupt Controller

The Arm Generic Interrupt Controller (GIC) architecture has two forms in general use with the A-profle that are also applicable to the R-profile:

GICv2 is a memory mapped solution supporting up to eight processors.
GICv3 offers support for much higher interrupt counts and larger numbers of processors. This version includes support for the System registers in Armv8-A and Armv8-R designs.
GICv4 adds supports the direct injection of virtual interrupts.

The M-profile has its own NVIC interrupt controller as an integral part of the M-profile architecture.
