Argh, just saw that I misread defconfig for DT here, sorry. But the
argument still stands: the SoPine module itself has only a bit of
functionality and is not usable on its own, so any board configuration
must be considered as being together with some kind of base board.
For instance the eMMC, HDMI socket and Ethernet PHY is not on the SoPine
module.

Cheers,
Andre.
