Hello Grischa,

Thanks for your report!
I have marked the mainboard as supported and will commit that later
together with other small changes.

the chips are not found "at the same address", but report the same ID
when queried. atmel did no give them distinct IDs so we can not
distinguish them on our own, hence your help was required*, sorry.

* i have not looked at the respective datesheets. it is possible that
  the other definition would work equally.
