2 | UEFI Firmware Management Protocol definition\r | |
6e746540 HW |
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 | |
252b9c7a | 5 | identifying firmware image revision level and programming the image into the device.\r |
6 | \r | |
6e746540 HW |
7 | GetImageInfo() is the only required function. GetImage(), SetImage(),\r |
8 | CheckImage(), GetPackageInfo(), and SetPackageInfo() shall return\r | |
252b9c7a | 9 | EFI_UNSUPPORTED if not supported by the driver.\r |

348 | IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED. The function returns\r | |
252b9c7a | 349 | EFI_SECURITY_VIOLATION if the validation fails.\r |
6e746540 HW |
350 | - Validate the image is a supported image for this device. The function returns EFI_ABORTED if\r |
351 | the image is unsupported. The function can optionally provide more detailed information on\r | |
252b9c7a | 352 | why the image is not a supported image.\r |
6e746540 HW |
353 | - Validate the data from VendorCode if not null. Image validation must be performed before\r |
354 | VendorCode data validation. VendorCode data is ignored or considered invalid if image\r | |
355 | validation failed. The function returns EFI_ABORTED if the data is invalid.\r | |
356 | \r | |
357 | VendorCode enables vendor to implement vendor-specific firmware image update policy. Null if\r | |
358 | the caller did not specify the policy or use the default policy. As an example, vendor can implement\r | |
359 | a policy to allow an option to force a firmware image update when the abort reason is due to the new\r | |
360 | firmware image version is older than the current firmware image version or bad image checksum.\r | |
252b9c7a | 361 | Sensitive operations such as those wiping the entire firmware image and render the device to be\r |
362 | non-functional should be encoded in the image itself rather than passed with the VendorCode.\r | |

364 | reason to the caller.\r | |
