Some field names in the IORT table parser were longer than the
OUTPUT_FIELD_COLUMN_WIDTH plus indentation, resulting in loss of
the output print alignment. Therefore, abbreviate the field names.

The IORT table generator is setting up a reference to ID array for
nodes even when the ID Mapping count is zero. This is not an issue as an
OS would only access the ID Reference if the ID mapping count is not zero.
However, it would be good to set the reference to ID array to zero when
the ID Mapping count is zero rather than populating it with an incorrect
value.

The IORT generator is populating the reference field for Context and
PMU interrupts even if their count is zero.
Update the IORT generator to set the references only if the interrupt
count is not 0. Also add checks to ensure a valid reference token has
been provided.

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 header file to reflect these changes,
and also rename the EFI_ACPI_IO_REMAPPING_TABLE_REVISION macro to
EFI_ACPI_IO_REMAPPING_TABLE_REVISION_00.
Also update the IORT generator in DynamicTablesPkg to fix the
compilation errors so that Git Bisect can work.

Notes:
v6:
- Add definition for IORT Rev 4 and RMR Node Rev 2. [PIERRE]
- Added definition for IORT Rev 4 and RMR Node 2 so that [SAMI]
appropriate checks can be performed for deprecated
table/node revisions.
v5:
- Change IORT revision macro name to make it similar to [THOMAS]
macro names for other ACPI tables.
- Updated IORT revision macros from [SAMI]
EFI_ACPI_IO_REMAPPING_TABLE_REVx to
EFI_ACPI_IO_REMAPPING_TABLE_REVISION_0x
Ref: https://edk2.groups.io/g/devel/message/91119
- Keep EFI_ACPI_IO_REMAPPING_TABLE_REVISION and set to [LIMING]
EFI_ACPI_IO_REMAPPING_TABLE_REVISION_05.
Ref: https://edk2.groups.io/g/devel/message/91137
- Added EFI_ACPI_IO_REMAPPING_TABLE_REVISION and set it [SAMI]
to the latest IORT revision.
- Updated IORT generator in DynamicTablesPkg and included [SAMI]
in this patch so that Git bisect does not break.
v4:
- Updated patch series to IORT specification revision E.d. [SAMI]
- Add flag to indicate if the root complex supports PASID. [SAMI]
- Add flags to define access privilege and attributes for [SAMI]
the memory ranges.
v3:
- Submit patch series to update platform code to use the [LIMING]
EFI_ACPI_IO_REMAPPING_TABLE_REV0 macro.
Ref: https://edk2.groups.io/g/devel/topic/83618423#76799
- Removed definition of EFI_ACPI_IO_REMAPPING_TABLE_REVISION [SAMI]
as EFI_ACPI_IO_REMAPPING_TABLE_REV0 has been provided for
representing Rev 0. Also, a corresponding patch series
for updating the platforms in edk2-platforms repository
shall be submitted to the edk2 mailing list.
- Include r-b received from v2 series. [SAMI]
Ref: https://edk2.groups.io/g/devel/topic/83600724#76660
v2:
- Set EFI_ACPI_IO_REMAPPING_TABLE_REVISION to Rev 0 as [SAMI]
setting to Rev 3 will break existing platforms. The
problem is that existing code would not be populating
the Identifier field in the nodes. This can lead to
non-unique values in the Identifier field.

> Ref: https://edk2.groups.io/g/devel/message/91137
> - Added EFI_ACPI_IO_REMAPPING_TABLE_REVISION and set it [SAMI]
> to the latest IORT revision.
> - Updated IORT generator in DynamicTablesPkg and included [SAMI]
> in this patch so that Git bisect does not break.
>
> v4:
> - Updated patch series to IORT specification revision E.d. [SAMI]
> - Add flag to indicate if the root complex supports PASID. [SAMI]
> - Add flags to define access privilege and attributes for [SAMI]
> the memory ranges.
> v3:
> - Submit patch series to update platform code to use the [LIMING]
> EFI_ACPI_IO_REMAPPING_TABLE_REV0 macro.
> Ref: https://edk2.groups.io/g/devel/topic/83618423#76799
> - Removed definition of EFI_ACPI_IO_REMAPPING_TABLE_REVISION
> [SAMI]
> as EFI_ACPI_IO_REMAPPING_TABLE_REV0 has been provided for
> representing Rev 0. Also, a corresponding patch series
> for updating the platforms in edk2-platforms repository

> - Include r-b received from v2 series. [SAMI]
> Ref: https://edk2.groups.io/g/devel/topic/83600724#76660
>
> v2:
> - Set EFI_ACPI_IO_REMAPPING_TABLE_REVISION to Rev 0 as [SAMI]
> setting to Rev 3 will break existing platforms. The
> problem is that existing code would not be populating
> the Identifier field in the nodes. This can lead to
> non-unique values in the Identifier field.

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.
Signed-off-by: Sami Mujawar <sami.mujawar@arm.com>
---
Notes:
v6:
- Make output format for Flags filed consistent. [PIERRE]
- Define macro for IORT Rev E.c and RMR Node revision 2 [PIERRE]
and use these to check for deprecated table/node
revisions.
- Identifier field size changed between IORT revision E [PIERRE]
and E.a. so extra checks should be needed.
- Added check to skip parsing if IORT Rev E, E.<a,b,c> [SAMI]
as various fields were deprecated between revisions.
v5:
- No code change since v4. Included r-b received for [SAMI]
v5 series.
v4:
- Add validation to check that the IORT Table Revision is [SAMI]
not 4 as IORT Rev E.c is deprecated.
- Add validation to check that the IORT RMR node revision [SAMI]
is not 2 as it breaks backward compatibility and was
deprecated as part of IORT Rev E.c.
v3:
- No code change since v1. Included r-b received for [SAMI]
v2 series.
Ref: https://edk2.groups.io/g/devel/topic/83600720#7665
v2:
- No code change since v1. Re-sending with v2 series. [SAMI]

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 Arm namespace objects to:
- add Identifier field to IORT nodes.
- introduce enums to represent RMR nodes and Memory Range
descriptors.
- add definition of node type 6 - Reserved Memory Range node.
- add definition for Memory Range Descriptors.
- add PASID capabilities and flags field to Root Complex node.

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>.

Notes:
v6:
- Add check to not generate IORT Rev E, E.<a,b,c>. [PIERRE]
- Added checks to not generate IORT table Rev E, E.<a,b,c>. [SAMI]
v5:
- Change IORT revision macro name to make it similar to [THOMAS]
macro names for other ACPI tables.
- Updated IORT revision macros from [SAMI]
EFI_ACPI_IO_REMAPPING_TABLE_REVx to
EFI_ACPI_IO_REMAPPING_TABLE_REVISION_0x
Ref: https://edk2.groups.io/g/devel/message/91119
- Minor updates initialise RcNode.PasidCapabilities in [SAMI]
case of EFI_ACPI_IO_REMAPPING_TABLE_REVISION_00 so that
backward compatibility is maintained.
v4:
- Update IORT generator to support spec revision E.d [SAMI]
- Populate the PASID capabilities and Flags field of the [SAMI]
Root complex node.
v3:
- Move error handling for IdMappingToken. [PIERRE]
- Moved error handling for IdMappingToken in a separate [SAMI]
patch in v3 series.
Ref: https://edk2.groups.io/g/devel/topic/83600726#76661
v2:
- The macro EFI_ACPI_IO_REMAPPING_TABLE_REVISION was set to [SAMI]
Rev 0 as setting to Rev 3 will break existing platforms.
Therefore, set the max supported IORT generator revision
to 3.
