  2. EDKII Platform Has Device Tree GUID
  3. A NULL protocol instance with this GUID in the DXE protocol database, and/or
  4. a NULL PPI with this GUID in the PPI database, implies that the platform
  5. provides the operating system with a Device Tree-based hardware description.
  6. Note that this is not necessarily exclusive with different kinds of hardware
  7. description (for example, an ACPI-based one). A platform driver and/or PEIM
  8. is supposed to produce a single instance of the protocol and/or PPI (with
  9. NULL contents), if appropriate.
