When CONFIG_SECURE_BOOT is enabled, the signed images like kernel and dtb can be authenticated using iMX6 CAAM. The added command hab_auth_img can be used for HAB authentication of images. The command takes the image DDR location, IVT (Image Vector Table) offset inside image as parameters. Detailed info about signing images can be found in Freescale AppNote AN4581.
