| 6 | Example FIT image description file demonstrating the usage |
| 7 | of SEC Firmware and multiple loadable images loaded by U-Boot. |
| 8 | For booting PPA (SEC Firmware), "firmware" is searched and loaded. |
| 9 | |
| 10 | Multiple binaries will be loaded as "loadables" (if present) at their |
| 11 | respective load offsets from firmware image address. |
