| 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 | |
