The CM_STD_OBJ_ACPI_TABLE_INFO.AcpiTableRevision can be used to specify
the major revision number of the ACPI table that the generator must use.
Although most ACPI tables only have a major revision number, the FADT
table additionally has a minor revision number.
The FADT generator currently defaults to setting the latest supported
ACPI revision for the FADT table i.e. ACPI 6.4. This means that the minor
revision for the FADT table is always set to 4 and there is no provision
for a user to specify the minor revision to be selected.
Therefore, update CM_STD_OBJ_ACPI_TABLE_INFO to introduce a new field
MinorRevision which can be used to specify the minor revision for an
ACPI table. Also update the FADT generator to validate the supported
FADT revisions ans use the specified minor revision for the FADT table
if supported. If an unsupported minor revision is specified the FADT
generator defaults to the latest supported minor revision.
Since the CM_STD_OBJ_ACPI_TABLE_INFO.MinorRevision field is added to
the end of the structure, it should not break existing platform code.

In ACPI 6.4, s6.2.13, _PRT objects describing PCI legacy interrupts
can be defined following 2 models.
In the first model, _PRT entries reference link devices. Link devices
then describe interrupts. This allows to dynamically modify
interrupts through _SRS and _PRS objects and to choose exactly the
interrupt type (level/edge triggered, active high/low).
In the second model, interrupt numbder are described in the _PRT entry.
The interrupt type is then assumed by the OS.
The Arm BSA, sE.6 "Legacy interrupts" states that PCI legacy
interrupts must be converted to SPIs, and programmed level-sensitive,
active high. Thus any OS must configure interrupts as such and there
is no need to specify the interrupt type.
Plus it is not possible to dynamically configure PCI interrupts.
Thus remove the link device generation and use the second model
for _PRT.

Hardware information parser is an optional module defined

repository.
FdtHwInfoParser library is an instance of a HwInfoParser

FdtHwInfoParser library is aimed at providing a solution
for generating ACPI tables for Guest Partitions launched
by virtual machine managers (VMMs). One such use case is
Kvmtool where the Device Tree for the Guest is passed on
to the firmware by Kvmtool. The Configuration Manager for
Kvmtool firmware shall invoke the FdtHwInfoParser to parse
the Device Tree to populate the hardware information in
the Platform Info Repository. The Kvmtool Configuration
Manager can the process this information to generate the
required ACPI tables for the Guest VM.
This approach also scales well if the number of CPUs or
if the hardware configuration of the Guest partition is
varied.
FdtHwInfoParser thereby introduces 'Dynamic Tables for
Virtual Machines'.
