   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.
