Did this to illustrate my understanding of the firmware generations: Valo and Kone were 1st generation Arvo was externaly developed and lies in the middle All others until now are considered 2nd generation Signed-off-by: Stefan Achatz <erazor_de@users.sourceforge.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
