This is an import of the fw-2 tag of tkey-libs. We import the entire tkey-libs repo minus dot files into the tillitis-key1 repo to make it very simple not to make mistakes regarding which firmware tag depends on which tkey-libs tag, especially considering locking down with NVCM. Please see README for information about developing with another tkey-libs or how to import future tkey-libs. Since tkey-libs is now a part of the repo we also add tkey-libs to the clean_fw target.
