From: Michael Ring <[email protected]> The BananaPro uses uart4 for the default rx/tx pins on the 40 pins connector, so enable uart4.
Uart2 is also available at the bananapro io-pins, but like on the bananapi the primary function of the pins is to act as gpios, see: http://forum.lemaker.org/forum.php?mod=viewthread&tid=10852 Disable the uart2 node by default, but leave it in place so that people can easily enable it.
