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

 307   Updates the firmware image of the device.

 309   This function updates the hardware with the new firmware image.
 310   This function returns EFI_UNSUPPORTED if the firmware image is not updatable.
 311   If the firmware image is updatable, the function should perform the following minimal validations
 312   before proceeding to do the firmware image update.
 313   - Validate the image authentication if image has attribute
 314     IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED.  The function returns
 315     EFI_SECURITY_VIOLATION if the validation fails.
 316   - Validate the image is a supported image for this device.  The function returns EFI_ABORTED if
 317     the image is unsupported.  The function can optionally provide more detailed information on
 318     why the image is not a supported image.
 319   - Validate the data from VendorCode if not null.  Image validation must be performed before
 320     VendorCode data validation.  VendorCode data is ignored or considered invalid if image
 321     validation failed.  The function returns EFI_ABORTED if the data is invalid.
 322
 323   VendorCode enables vendor to implement vendor-specific firmware image update policy.  Null if
 324   the caller did not specify the policy or use the default policy.  As an example, vendor can implement
 325   a policy to allow an option to force a firmware image update when the abort reason is due to the new
 326   firmware image version is older than the current firmware image version or bad image checksum.
 327   Sensitive operations such as those wiping the entire firmware image and render the device to be
 328   non-functional should be encoded in the image itself rather than passed with the VendorCode.
 329   AbortReason enables vendor to have the option to provide a more detailed description of the abort
 330   reason to the caller.

 401                                        The format is vendor specific and new version must have a greater value
