15 * Following descriptor provides BL image/ep information that gets used
16 * by BL2 to load the images and also subset of this information is
17 * passed to next BL image. The image loading sequence is managed by
18 * populating the images in required loading order. The image execution
19 * sequence is managed by populating the `next_handoff_image_id` with
20 * the next executable image id.
