I've just become involved in a project which is using U-boot as the bootloader. This is a smallish embedded system. I'm trying to find the right way to handle the use of U-boot. What sort of acknowledgements, source code availability, etc. are expected here.
U-Boot is Free Software under GPL, so you just have to make sure to follow the GPL license requiements. No further acknowledgementes etc. are needed. Of course it is always a clever idea to push your changes upstream so your port gets maintained and you have a much easier patch in case you ever want to update U-Boot to a more current version.
U-boot isn't ever visible to the user; the system boots up and launches the application. There is a small LCD screen; and really nowhere to display much. Minor changes have been made to the U-boot source; to customize it for the hardware and the software download of new firmware.
Well, please read the GPL. At least you must include with your product a statement that you are using GPL software and a written offer (valid for at least 3 years) to provide the complete source code.
