This commit add to u-boot the support to decrypt fit image encrypted with aes. The FIT image contains the key name and the IV name. Then u-boot look for the key and IV in his device tree and decrypt images before moving to the next stage. Signed-off-by: Philippe Reynes <philippe.reynes@softathome.com>
