This patch adds a check for the default FIT config to iminfo. Once applied any signing of the config will show a pass fail similar to rsa+/rsa-.
Output looks like this:
Hash(es) for Image 0 (kernel@1): sha1+ Hash(es) for Image 1 (fdt@imx7s-warp.dtb): sha1+ Hash(es) for Image 2 (ramdisk@1): sha1+ Hash(es) for Image 3 (bootscr): sha1+ Hash for default configuration: sha1,rsa2048:mbl-fit-rot-key+
