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

	214	This function updates the hardware with the new firmware image.\r
	215	This function returns EFI_UNSUPPORTED if the firmware image is not updatable.\r
