9e865f9579 ShellPkg/AcpiView: Update print-formatter prototype
As of now, the print-formatter implemented by the FNPTR_PRINT_FORMATTER
function pointer takes two parameters, the format string and the pointer
to the field. For cases where the print-formatter has to have access to
the length of the field, there is no clean way to currently do it. In
order to resolve this, update the print-formatter's prototype to take
the length of the field as a third parameter. This change should improve
the overall robustness and flexibility of AcpiView.

function pointer takes two parameters, the pointer to the field and a

validation logic. This change should improve the overall robustness and

Bugzilla: 3995 (https://bugzilla.tianocore.org/show_bug.cgi?id=3995)

ACPI 6.4 spec states that if the revision field in the DSDT header is less
than 2, then all integers are restricted in width to 32 bits, including in
SSDTs.

Arm Base boot requirements state that platforms must conform to ACPI 6.3
or later, and that legacy tables are not supported.

Adds a check for this field and raise warning if revision is less

cd67efa1b2 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.

b85048261a ShellPkg: acpiview: Prevent infinite loop if structure length is 0
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2534

Extend validation of ACPI structure lengths which are read from the
ACPI table being parsed. Additionally check if the structure 'Length'
field value is positive. If not, stop parsing the faulting table.

Some ACPI tables define internal structures of variable size. The
'Length' field inside the substructure is used to update a pointer used
for table traversal. If the byte-length of the structure is equal to 0,
acpiview can enter an infinite loop. This condition can occur if, for
example, the zero-allocated ACPI table buffer is not fully populated.
This is typically a bug on the ACPI table writer side.

In short, this method helps acpiview recover gracefully from a
zero-valued ACPI structure length.

eb9db72ca8 ShellPkg: acpiview: SLIT: Validate System Locality count
1. Check if the 'Number of System Localities' provided can be
represented in the SLIT table. The table 'Length' field is a 32-bit
value while the 'Number of System Localities' field is 64-bit long.

2. Check if the SLIT matrix fits in the table buffer. If N is the SLIT
locality count, then the matrix used to represent the localities is
N*N bytes long. The ACPI table length must be big enough to fit the
matrix.

3. Remove (now) redundant 64x64 bit multiplication.
