Chris Jones 942c9bd357 ShellPkg: Update Acpiview GTDT parser to ACPI 6.4
Bugzilla: 3565 (https://bugzilla.tianocore.org/show_bug.cgi?id=3565)

Update the Acpiview GTDT parser to use Acpi64.h and as such rename all
occurences of "SBSA Generic Watchdog" to "Arm Generic Watchdog".

Tomas Pilar e18ac66d84 ShellPkg/AcpiView: Refactor configuration
A new file and header (AcpiViewConfig.[ch]) is created
that houses the user configuration. This declutters the
core code and improves modularity of the design.

The module level symbols for verbosity, table selection, and
highlighting are refactored into the new file.

Krzysztof Koch 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.

Krzysztof Koch 1d12f0e671 ShellPkg: acpiview: GTDT: Prevent buffer overruns
Modify the GTDT table parsing logic to prevent reading past the ACPI
buffer lengths provided and to make it consistent with other table
parsers. This includes converting the do-while loop in ParseAcpiGtdt()
into a while loop.

Remove a check which ensures that the entire Platform GT Block
Structure buffer has been parsed. The ACPI specification does not ban
from defining buffers which are larger than the size indicated by the
count and sizes of substructures which constitute it.

Change the data type of the Length parameter to the DumpGTBlock()
function to reflect the width of the respective ACPI structure's
field.

Krzysztof Koch 2a219e196d ShellPkg: acpiview: GTDT: Remove redundant forward declarations
Remove redundant forward function declarations by repositioning
blocks of code. This way the code structure is consistent across
ACPI table parsers and the code becomes more concise.

Replace multple use of literal values for GT Block Timer Frame
count/number validation with a macro definition.

Ruiyu Ni ee4dc24f57 ShellPkg: Add acpiview tool to dump ACPI tables
This program is provided to allow examination of ACPI table contents
from the UEFI Shell.  This can help with investigations, especially at
that stage where the tables are not enabling an OS to boot.
The program is not exhaustive, and only encapsulates detailed knowledge
of a limited number of table types.

Default behaviour is to display the content of all tables installed.
'Known' table types will be parsed and displayed with descriptions and
field values.  Where appropriate a degree of consistency checking is
done and errors may be reported in the output.
Other table types will be displayed as an array of Hexadecimal bytes.

To facilitate debugging, the -s and -d options can be used to generate a
binary file image of a table that can be copied elsewhere for
investigation using tools such as those provided by acpica.org.  This is
especially relevant for AML type tables like DSDT and SSDT.

The inspiration for this is the existing smbiosview Debug1 Shell
command.

Many tables are not explicitly handled, in part because no examples are
available for our testing.

The program is designed to be extended to new tables with minimal
effort, and contributions are invited.
