Detailed Description

Implementiation of a GIC-400 List Register-based VGIC interface.

The VGIC is, in this implementation, completely separate from the GIC itself. Only a VIRQ line to the CPU and a PPI line to the GIC (for a HV maintenance IRQ) is required.

The mode in which the List Registers may flag (via LR.HW) that a hardware EOI is to be performed is NOT supported. (This requires tighter integration with the GIC.)
