ACPICA: IORT: Update for revision D
IORT revision D contains a few additions and fixes to currently-supported tables: - SMMUv3 proximity domain field is enlarged to 4 bytes for consistency with SRAT - Root complex nodes gain an address size limit field equivalent to that of named components - Named component nodes gain a way to describe PASID (substream_ID) support, encoded in their flags Additionally, we fix a couple of outstanding points in passing: - Add the stall support flag for named components defined in revision C - Fix SMMUv3 HTTU override mask, which should always have been 2 bits Signed-off-by: Robin Murphy <robin.murphy@arm.com> Signed-off-by: Erik Schmauss <erik.schmauss@intel.com> Signed-off-by: Rafael J.
