We are currently celebrating 15 years of i.MX support in mainline Linux: https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git/commit/?id=9c496bde802b19db40325bbde356be62e66dc125 For this I took some time to update the i.MX1 based Synertronix scb9328 board support. With the switch to device tree support the board is able to boot up a recent barebox and a current mainline Linux, see here: https://asciinema.org/a/VPg3yPZBZfhhqMVN61fAX38Cm The board only has 16MiB of SDRAM which is very tight nowadays. For successful boot I have some additional hack in my tree which arranges the Kernel and device tree in memory in a way that the device tree won't get overwritten during decompression of the Kernel. Also I wasn't able to start my systemd based rootfs, probably due to memory constraints. With init=/bin/sh it works though, but hey, it's a more than 15 years old hardware ;) Have Fun!
