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