Among those ones, uart2 has dedicated pin slot which is used to console log. uart[0-1] appear at the 40-pins connector and uart3 has no pinout, but just has test points (TP47 for TX and TP48 for RX, respectively) nearby uart2, but we don't enable uart3 in the patch. The missing pinctrl is also being supplemented for those newly added devices.
