DynamicTablesPkg: IORT generator updates for Rev E.d spec
Bugzilla: 3458 - Add support IORT Rev E.d specification updates
(https://bugzilla.tianocore.org/show_bug.cgi?id=3458)
The IO Remapping Table, Platform Design Document, Revision E.d,
Feb 2022 (https://developer.arm.com/documentation/den0049/)
introduces the following updates, collectively including the
updates and errata fixes to Rev E, Rev E.a, Rev E.b, Rev E.c:
- increments the IORT table revision to 5.
- updates the node definition to add an 'Identifier' field.
- adds definition of node type 6 - Reserved Memory Range node.
- adds definition for Memory Range Descriptors.
- adds flag to indicate PRI support for root complexes.
- adds flag to indicate if the root complex supports forwarding
of PASID information on translated transactions to the SMMU.
- adds flag to indicate if the root complex supports PASID.
- adds flags to define access privilege and attributes for the
memory ranges.
Therefore, update the IORT generator to:
- increment IORT table revision count to 5.
- populate Identifier filed if revision is greater than 4.
- add support to populate Reserved Memory Range nodes and
the Memory range descriptors.
- add validation to check that the Identifier field is
unique.
- Populate the PASID capabilities and Flags field of the
Root complex node.
- Added checks to not generate IORT Rev E, Rev E.<a,b,c>.
