IORT revision E.b (ARM DEN 0049E.b) contains a few additions like,
    -Added an identifier field in the node descriptors to aid table
     cross-referencing.
    -Introduced the Reserved Memory Range(RMR) node. This is used
     to describe memory ranges that are used by endpoints and require
     a unity mapping in SMMU.
    -Introduced a flag in the RC node to express support for PRI.
    -Added a flag in the RC node to declare support for PASID forward
     information.
