Subject: [PATCH 3/8] ARM64: dts: marvell: armada37xx: Enable memory-mapped GIC
|
||
|
|
CPU interface
|
||
|
|
|
||
|
|
The Cortex-A53s that power the Armada-37xx SoCs are equipped with
|
||
|
|
a GIC CPU interface that gets enabled when coupled with a GICv3
|
||
|
|
interrupt controller, such as the GIC-500 on the this SoC.
|
||
|
|
|
||
|
|
Advertise the MMIO ranges provided by the CPUs, which enables
|
||
|
|
(among other things) GICv2 guests to run under a hypervisor such
|
||
|
|
as KVM.
|
||
