[Xen-devel] [PATCH v9 1/8] xen/arm: gic-v3: Increase the size of GICR in address space for guest

[Chen Baozi <cbz@xxxxxxxxxx>]

From: Chen Baozi <baozich@xxxxxxxxx>

Currently it only supports up to 8 vCPUs. Increase the region to hold
up to 128 vCPUs, which is the maximum number that GIC-500 supports.
