Currently our boards are completely described in .conf files which are
not in ethernut's repository.
We should be able to select a "None" board so that can still be done
externally from Nut/OS code and in the application code.

Then we do need the configurator to disable driver compilation and have some:

#ifdef <DRIVER>_ENABLED
NutDeviceRegister(&dev, &platform_data);
#endif

Otherwise we will pull in unused code and consume flash space.

I can give some help, we can coordinate in irc if you want.
