The recent Banana Pi BPI-F2S board features a new Arm SoC SP7021 by Sunplus, which is not yet supported in mainline Linux.
Prior to Hackweek I had prepared UART and interrupt controller drivers and Device Tree for Sunplus SP7021's Arm Cortex-A7 cores: GitHub branch f2s-next
Multiple YAML schema files need to be added before I can submit this upstream.
Another thing to investigate will be how to boot Linux on the companion ARM9 core.
