=====================================================
Feature Description
A driver should be implemented which support the GICv3 interrupt controller, for it's added benefits to
supported hardware, and lifting restrictions on core counts being very low. It is also important to note
that a GICv3 implementation may not be backwards compatible with the GICv2, requiring the creation
of this driver for hardware support.

Feature Benefits
List the reasons why this feature would be beneficial

• GICv3 is more common in newer hardware platforms, ie, i.MX8, RK33xx.
• GICv3 lifts restrictions from 8 CPUs to 512 CPUs
• GICv3 acts as system coprocessor, not as MMIO peripheral

Use case examples
List examples where this feature could be useful for end users.

• Allows for initial support for a real hardware port to RK33xx series SoC
• Allows for initial support for a real hardware port to i.MX8 series SoC
• Version under QEMU simulation can be changed to use GICv3 for testing
