TNX to tkaiser for in depth explanation of the Raspberry PI of the proprietary bootloader. Personally i own a Raspberry 1, a Raspberry 3 an Orange PI PC and a Tinkerboard and my question is now, can i contribute somehow eg. to the open firmware project (maybe a question for hojnikb) and how the policies of your project are? You only work with uboot and there is no option for a debian like "non-free" section for raspberry pi eg with such a script. https://github.com/braindef/debian_base_on_raspberry3 (i took from someone else and modified it for debian stretch)?
