See [[Linux_user_guide]] setup LInux OS generally;
The rockchip linux SDK source tree is located in multi Git repository hosted by Github. The SDK uses repo to sync down source code. Beside the generic community Linux support, we have chip optimized Linux SDK and it's also opensource and can get source from github.
