The number of vCPUs requested for a boot-time Arm domain is not bounded solely by Xen's generic domain limits. For GICv3 domains using the host memory layout, Xen can only create vCPUs whose virtual redistributor frame is covered by redistributor MMIO regions exposed for that layout. This can affect the hardware domain and direct-mapped domains. Document the GICv3-specific limit in the `cpus` property description in the Arm device-tree booting guide. Also add a generic domain-limit caveat to the `dom0_max_vcpus` command-line documentation. Signed-off-by: Mykola Kvach <mykola_kvach@epam.com> Reviewed-by: Michal Orzel <michal.orzel@amd.com>
