This seems like it ought to be under drivers/ somewhere, either
drivers/usb/Kconfig or drivers/input/Kconfig perhaps.

Is this the only platform with video+usb which you have? What about e.g.
cubie*, bananapi etc?

Ah, here are the settings I asked about earlier. Are these in the wrong
patch or did something change in this patch which makes them needed only

I'm not sure but I wonder if the cpp string pasting thing I suggested
earlier would reduce the amount of #else and duplication around here?

I suggest to #define CONSOLE_ENV_SETTINGS as the other two, and add STD
to their names.
