  16   The function is used to do the authentication for FMP capsule based upon
  17   EFI_FIRMWARE_IMAGE_AUTHENTICATION.
  18
  19   The FMP capsule image should start with EFI_FIRMWARE_IMAGE_AUTHENTICATION,
  20   followed by the payload.
  21
  22   If the return status is RETURN_SUCCESS, the caller may continue the rest
  23   FMP update process.
  24   If the return status is NOT RETURN_SUCCESS, the caller should stop the FMP
  25   update process and convert the return status to LastAttemptStatus
  26   to indicate that FMP update fails.
  27   The LastAttemptStatus can be got from ESRT table or via
  28   EFI_FIRMWARE_MANAGEMENT_PROTOCOL.GetImageInfo().
  29
  30   Caution: This function may receive untrusted input.

  32   @param[in]  Image                   Points to an FMP authentication image, started from EFI_FIRMWARE_IMAGE_AUTHENTICATION.
  33   @param[in]  ImageSize               Size of the authentication image in bytes.
  34   @param[in]  PublicKeyData           The public key data used to validate the signature.
  35   @param[in]  PublicKeyDataLength     The length of the public key data.

  38                                     The LastAttemptStatus should be LAST_ATTEMPT_STATUS_SUCCESS.
  39   @retval RETURN_SECURITY_VIOLATION Authentication fail.
  40                                     The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_AUTH_ERROR.
  41   @retval RETURN_INVALID_PARAMETER  The image is in an invalid format.
  42                                     The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_INVALID_FORMAT.

  44                                     The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_INVALID_FORMAT.

  46                                     The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_INVALID_FORMAT.

  48                                     The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_INSUFFICIENT_RESOURCES.
