Introduce a CM_ARCH_COMMON_COOLING_DEVICE_INFO object to describe
cooling devices provided by the platform. The generator creates one
SMBIOS Type 27 record for each cooling device object and populates the
device type/status, cooling unit group, OEM-defined data, nominal speed,
and optional description string.
The temperature probe handle is set to 0xFFFF for now because SMBIOS
Type 28 Temperature Probe generation is not currently available. Reject
non-null temperature probe tokens until Type 28 handle resolution can be
added.
Add the CM object parser entry and wire the generator into the
DynamicTablesPkg build.

The Generic ACPI for Arm Components 1.2 Platform Design Document [1],
section 2.6.1.2 "ASL reference code for the DMC620 PMU" provides
information to describe the Arm Corelink DMC620 Dynamic Memory
Controller's Performance Monitoring Unit (PMU) block using an ASL
definition block table.
Add support for a table generator for the DMC620 PMU block. The table
generator uses the Configuration Manager protocol to obtain the
following information.
- Number of sockets on the platform
- DMC620 devices per socket
After obtaining the socket based topology, information is obtained on
individual DMC620 devices. This includes
- PMU register base address and length
- Information on the associated PMU interrupt
The table generator uses the Dynamic AML CodeGen API's for generating
the table from the information obtained through the Configuration
Manager protocol.

The SRAT/HMAT/SLIT tables describe the relations between
ProximityDomain IDs. These proximity domains might represent
memory domains, CPUs, IO, etc.
ProximityDomain IDs are mere IDs. They don't represent anything
and could be generated by the DynamicTablesPkg framework. These
IDs are currently hard-coded by the ConfigurationManager developer.
In order to:
- avoid the developer to keep track of the used ProximityDomain IDs
- have a better internal representation of the relation between
CPUs sharing the same ProximityDomain ID
allow the developer to use Tokens pointing to ProximityDomain
structures.
