Just basic support, so we get a shell on mini-uart and SD working. Needs more work for USB and Ethernet, but I'll leave that to others now that the initial hurdle is overcome. I tested this series on Raspberry Pi 3b (both 32-bit and newly added 64-bit support) and Raspberry Pi 4b (both 32/64-bit). @Oleksij, could you give this a test on Raspberry Pi 2 as well? barebox-dt-2nd.img is the image to use for all configurations. barebox didn't start up (or at least serial was silent) with Daily built Debian raspi_4_bullseye.img. Worked fine though with firmware in 2022-04-04-raspios-bullseye-arm64-lite.img. If in doubt, use firmware described in barebox documentation.
