AFAIK C906 is not open-source.
The open-source variant of C906 is called OpenC906, and we don't know the eventual difference between C906 and OpenC906.
Even if the C906 and OpenC906 were the same there would be no way to verify that the cores implemented in the hardware you receive are the same as those described anyway.
