The Platform information repository in the Configuration Manager may be dynamically populated, for e.g. by a Hardware Information Parser like FdtHwInfoParser. In such cases it is useful to trace the CM objects that were populated by the parser. Therefore, introduce helper functions that can parse and trace the Configuration Manager Objects.
