Booting the firmware requires some information regarding offsets within the firmware binary. These are passed through the device tree, but since the values vary depending on the firmware version, and the firmware itself is not available to the OS, the flasher is expected to provide a device tree overlay with values corresponding to the firmware it is flashing. The overlay then replaces the placeholder values here.
