Thread-topic: [XEN PATCH 0/4] arm: Add GICv3 support to the New VGIC

Hi All. This patch aims to add GICv3 support to the New VGIC. It adds support for the GICv3 distributor, redistributor, sysreg and ITS interfaces. This will allow Xen to emulate level-triggered interrupts with GICVb3 and will make the NEW_VGIC more complete and usable. The bulk of the code is taken from the Linux Kernel v6.0 and adapted to the existing Xen codebase. For the NEW_VGIC config the !GIC_V3 dependency is removed. For the HAS_ITS config the deprecated flag is removed and NEW_VGIC dependency is added. Original non-ported changes are: - Moving the GICv3 distributor base to fix the new_vgic's intid calculation. - Moving the get/put irq to a wider scope to properly integrate the ITS.
