Previously, the rpiboot tool duplicated some scripts from the rpi-eeprom repo (e.g. rpi-eeprom-config) for modifying the EEPROM images offline and for secure-boot.

Since these scripts are still under development it's best to avoid duplicating them so we've removed them from the `usbboot` repo and included them by using `rpi-eeprom` as a git submodule.

This doesn't change the behaviour of the tool but if you are building this from source then the git clone command changes
