4 * (Bogus) example FIT image description file demonstrating the usage
5 * of multiple images loaded by the SPL.
6 * Several binaries will be loaded at their respective load addresses.
7 *
8 * For booting U-Boot, "firmware" is searched first. If not found, "loadables"
9 * is used to identify images to be loaded into memory. If falcon boot is
10 * enabled, "kernel" is searched first. If not found, it falls back to the
11 * same flow as booting U-Boot. Changing image type will result skipping
12 * specific image.
13 *
14 * Finally the one image specifying an entry point will be entered by the SPL.
