    RSA provides a public key encryption facility which is ideal for image
    signing and verification.
    
    Images are signed using a private key by mkimage. Then at run-time, the
    images are verified using a private key.
    
    This implementation uses openssl for the host part (mkimage). To avoid
    bringing large libraries into the U-Boot binary, the RSA public key
    is encoded using a simple numeric representation in the device tree.
