ShellPkg: Acpiview: IORT parser update for IORT 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 parser to:
- parse the Identifier field.
- parse Reserved Memory Range node.
- parse Memory Range Descriptors.
- add validations to check that the physical range base
and size of the Memory Range Descriptor is 64KB aligned.
- add validation to check that the IORT Table Revision is
not 4 as IORT Rev E.c is deprecated.
- add validation to check that the IORT RMR node revision
is not 2 as it breaks backward compatibility and was
deprecated as part of IORT Rev E.c.
- skip parsing of IORT Rev E, Rev E.a, Rev E.b, Rev E.c as
some fields were deprecated in these revisions.
