+Reasons for removal:
+- The board is a custom design at the RWTH Aachen, so only two persons have
+  access to the hardware
+- It was unmaintained for several month now
+- Various refactoring PRs affected the ATmega CPU family have not been tested,
+  it is unclear if the board is actually usable with RIOT
