This serie adds a stage pre-load before launching an image. This stage is used to read a header before the image and this header contains the signature of the full image. So u-boot may check the full image before using any data of the image.
Changelog: v3: - move image-pre-load.c to /boot - update mkimage to add public key in u-boot device tree - add script gen_pre_load_header.sh v2: - move the code to image-pre-load - add support of stage pre-load for spl - add support of stage pre-load on spl_ram
