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