After remove "arm,cortex-a15-gic", I get the following error during
kernel booting:
-----
kvm [1]: Using HYP init bounce page @396d9000
kvm [1]: error: no compatible GIC node found
kvm [1]: error initializing Hyp mode: -19
-----
Check code "virt/kvm/arm/vgic.c", gicv2 only "cortex-a15-gic" and
gicv3 support kvm now,
so I think we should keep it, how about your idea?
Thanks,
Bintian
