My board boots via U-Boot and AFAIK that bootloader does not support device tree overlays, so I'm probably forced to generate a single, static
.dtb will all relevant overlays (and settings??) already applied to it. In principle that would be okay for me, but how to do that?
Is there some command line tool that takes
.dtbo files resp.
.dtsi files and combines them into a single
dtc doesn't seem to do that job.
The ultimate goal is to get I²C working on a Raspberry B+ that boots via U-Boot.
