Hi Julien/Zoli,
Hi Shameer,

I had a run of this staging on our D01 board.
Thank you for testing.
Xen fails to boot with below error:
(XEN) domain 0: vGIC requested is not supported
(XEN) CPU0: Unexpected Trap: Data Abort
After going through the code, it looks to me that hip04 gicv2_info is missing
the vgic_versions initialisation. Made the following changes and xen booted and
started dom0.

Please correct me, if this is not the correct way to init the vgic_versions.
This is correct. Although, I'm planning to rework the way that the GIC
tells the supported vGIC in the next version of this GICv2 on GICv3 series.
