   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.

 305   Updates the firmware image of the device.
 306
 307   This function updates the hardware with the new firmware image.
 308   This function returns EFI_UNSUPPORTED if the firmware image is not updatable.
 309   If the firmware image is updatable, the function should perform the following minimal validations
 310   before proceeding to do the firmware image update.
 311   - Validate the image authentication if image has attribute
 312     IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED.  The function returns
 313     EFI_SECURITY_VIOLATION if the validation fails.
 314   - Validate the image is a supported image for this device.  The function returns EFI_ABORTED if
 315     the image is unsupported.  The function can optionally provide more detailed information on
 316     why the image is not a supported image.
 317   - Validate the data from VendorCode if not null.  Image validation must be performed before
 318     VendorCode data validation.  VendorCode data is ignored or considered invalid if image
 319     validation failed.  The function returns EFI_ABORTED if the data is invalid.
 320
 321   VendorCode enables vendor to implement vendor-specific firmware image update policy.  Null if
 322   the caller did not specify the policy or use the default policy.  As an example, vendor can implement
 323   a policy to allow an option to force a firmware image update when the abort reason is due to the new
 324   firmware image version is older than the current firmware image version or bad image checksum.
 325   Sensitive operations such as those wiping the entire firmware image and render the device to be
 326   non-functional should be encoded in the image itself rather than passed with the VendorCode.
 327   AbortReason enables vendor to have the option to provide a more detailed description of the abort
 328   reason to the caller.
