I feel a bit nostalgic about ts7250, as it was my very first "embedded" Linux board, so i think it needs a proper retirement. So let me finish the full conversion on the top of 5.20+ and then we can think if it's suitable for plan "a". It won't take long, as i have a bootable BSP on branch [2]. > > Arnd _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
