# Note about this file moving madness:
# avr-ioe is using Kconfig for configuration and it is not prepared too well for
# nested projects (at least I don't know way). This unfortunately means that to
# have configuration in parent project, We have to move it every time we are
# generating it. Also upper projects can't use Kconfig for its self configuration.
