There was no other source for the topology files for a very long time. 
This has been quite recently changed with the introduction of avsdk [1] 
and avs-topology-xml [2] repos. These hold 2 major branches each:

1) main - for the avs-driver which has already replaced the 
skylake-driver in client department and shall soon do the same in the 
remaining areas
2) for-skylake-driver - for the skylake-driver, help downstream in 
dealing with bugs and ease the transition to the avs-driver

Updated AudioDSP firmware binaries should be shared soon, completing 
last few remaining steps. Not every library can be shared though. And 
can't comment on usage of 3rd party loadable modules outside of 
supported set of configurations.
