* (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.
