2013-06-26image: Add RSA support for image signingSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-26image: Support signing of imagesSimon Glass
Add support for signing images using a new signature node. The process is handled by fdt_add_verification_data() which now takes parameters to provide the keys and related information. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-06-26image: Add signing infrastructureSimon Glass
Add a structure to describe an algorithm which can sign and (later) verify images. Signed-off-by: Simon Glass <sjg@chromium.org>
