Signed CMC rmware image

The CMC rmware includes a signature. The CMC rmware performs a signature verication step to ensure the authenticity of the

uploaded rmware. The rmware update process is successful only if CMC authenticates the rmware image to be a valid image from the

service provider and has not been altered. The rmware update process is stopped if CMC cannot verify the signature of the uploaded

rmware image. A warning event is then logged and an appropriate error message is displayed. The rmware update includes upgrade and

downgrade.
