Bugzilla: 3458 - Add support IORT Rev E.b specification updates
(https://bugzilla.tianocore.org/show_bug.cgi?id=3458)
The IO Remapping Table (IORT) specification has been updated to
rev E.b. The following updates are introduced including the errata
to rev E and E.a:
- increments the IORT table revision to 3.
- 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.
Changes since v2 series:
- Dropped [PATCH v2 1/8] MdePkg: Fix IORT header file include
guard as suggested at
https://edk2.groups.io/g/devel/message/76656
- Removed definition of EFI_ACPI_IO_REMAPPING_TABLE_REVISION as
EFI_ACPI_IO_REMAPPING_TABLE_REV0 has been provided for
representing Rev 0.
- Moved error handling code for IdMappingToken from patch v2 6/8
and v2 8/8 into a separate patch.
- Moved Identifier field before Flags field in CM_ARM_RMR_NODE.
- Added description for CM_ARM_MEMORY_RANGE_DESCRIPTOR field.
The v2 patch series includes all changes from v1 patch series
except the following 2 patches have been modified to set the
EFI_ACPI_IO_REMAPPING_TABLE_REVISION macro to Rev 0 as setting
to Rev 3 will break existing platforms, the problem being that
the Identifier field in the IORT nodes would not be unique.
- MdePkg: IORT header update for IORT Rev E.b spec
- DynamicTablesPkg: IORT generator updates for Rev E.b spec
The v1 patch series:
- Updates the IORT header file to match the Rev E.b specification.
- Add support to parse IORT Rev E.b tables
- Add support to generate IORT Rev E.b compliant ACPI tables
using Dynamic Tables Framework.
