On my Banana Pro SATA works fine with the help of some userpatches. Take a look at the end of the thread http://forum.armbian.com/index.php/topic/836-bananapro-wifi-armbian-5-kernel-tracebacks/. I have attached my userpatches there.
Banana Pro uses a different DTS file, which is not as well maintained as those for the Banana Pi. Therefore, I have made a patch for sun7i-a20-bananapro.dts which this updated and solves some problems with the power supply.
