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