DynamicTablesPkg: Definition for HwInfoParser interface
Hardware information parser is an optional module defined
by the Dynamic Tables Framework. It can either parse an
XML, a Device Tree or a Json file containing the platform
hardware information to populate the platform information
repository.
The Configuration Manager can then utilise this information
to generate ACPI tables for the platform.
Therefore, define an interface for the HwInfoParser library
class.

DynamicTablesPkg: FdtHwInfoParser: Add Boot Arch parser
The Fixed ACPI Description Table (FADT) is a mandatory table
required for booting a standards-based operating system. The
FADT table has an 'ARM Boot Architecture Flags' field that is
used by an OS at boot time to determine the code path during
boot. This field is used to specify if the platform complies
with the PSCI specification. It is also used to describe the
conduit (SMC/HVC) to be used for PSCI.
The PSCI compliance information for a platform is described
in the platform Device Tree, the bindings for which can be
found at:

DynamicTablesPkg: FdtHwInfoParser: Add Serial port parser
The Microsoft Debug Port Table 2 (DBG2), the Serial Port Console
Redirector (SPCR) table are mandatory tables required for booting
a standards-based operating system. The DBG2 table is used by the
OS debugger while the SPCR table is used to configure the serial
terminal. Additionally, the serial ports available on a platform
for generic use also need to be described in DSDT/SSDT for an OS
to be able to use the serial ports.
The Arm Base System Architecture 1.0 specification a lists of
supported serial port hardware for Arm Platforms. This list
includes the following serial port UARTs:
- SBSA/Generic UART
- a fully 16550 compatible UART.
Along, with these the PL011 UART is the most commonly used serial
port hardware on Arm platforms.
The serial port hardware information is described in the platform
Device Tree, the bindings for which can be found at:
- linux/Documentation/devicetree/bindings/serial/serial.yaml
- linux/Documentation/devicetree/bindings/serial/8250.txt
- linux/Documentation/devicetree/bindings/serial/arm_sbsa_uart.txt
- linux/Documentation/devicetree/bindings/serial/pl011.yaml
The FdtHwInfoParser implements a Serial Port Parser that parses
the platform Device Tree to create CM_ARM_SERIAL_PORT_INFO objects
with the following IDs:
- EArmObjSerialConsolePortInfo (for use by SPCR)
- EArmObjSerialDebugPortInfo (for use by DBG2)
- EArmObjSerialPortInfo (for use as generic Serial Ports)
The Serial Port for use by SPCR is selected by parsing the Device
Tree for the '/chosen' node with the 'stdout-path' property. The
next Serial Port is selected for use as the Debug Serial Port and
the remaining serial ports are used as generic serial ports.
The CM_ARM_SERIAL_PORT_INFO objects are encapsulated in Configuration
Manager descriptor objects with the respective IDs and are added to
the platform information repository.
The platform Configuration Manager can then utilise this information
when generating the DBG2, SPCR and the SSDT serial port tables.

DynamicTablesPkg: Add FdtHwInfoParser library
Hardware information parser is an optional module defined
by the Dynamic Tables Framework. It can either parse an
XML, a Device Tree or a Json file containing the platform
hardware information to populate the platform information
repository.
FdtHwInfoParser library is an instance of a HwInfoParser
that parses a Device Tree and populates the Configuration
Manager Platform information repository.
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'.
