| | 2 | UEFI Firmware Management Protocol definition\r |
| | 3 | Firmware Management Protocol provides an abstraction for device to provide firmware\r |
| | 4 | management support. The base requirements for managing device firmware images include\r |
| | 5 | identifying firmware image revision level and programming the image into the device.\r |
| | 6 | \r |
| | 7 | GetImageInfo() is the only required function. GetImage(), SetImage(),\r |
| | 8 | CheckImage(), GetPackageInfo(), and SetPackageInfo() shall return\r |
| | 9 | EFI_UNSUPPORTED if not supported by the driver.\r |
