Thanks, before that I apply this, are you sure that v1 and v2 are similar
enough that we only need one config for them ? I'm asking because even if
they are similar enough from a u-boot pov, they still need a separate
defconfig if they need a separate dts.

It seems that v2 just swaps one usb port for a usb-wifi module, which
does not require dts changes. So this seems ok, and we can also add a
configs/Linksprite_pcDuino_v2_defconfig later I guess.

Also talking about the dts, I notice that the dts for the pcDuino_v3
has support for the gpio buttons found there, but the plain pcDuino
dts does not even though the v1 / v2 clearly have the gpio buttons too,
can you add support for those to the dts ? And the same question for
any leds which they may have (hard to see on pictures). This is also
a good check to see if they are really 100% compatible :)

Regards,

Hans
