This commit add the support of encrypting image with aes in mkimage. To enable the ciphering, a node cipher with a reference to a key and IV (Initialization Vector) must be added to the its file. Then mkimage add the encrypted image to the FIT and add the key and IV to the u-boot device tree. Signed-off-by: Philippe Reynes <philippe.reynes@softathome.com>
