Yocto for ROCK 2A

Are there plans for yocto support for the ROCK 2A board? I do not see conf files for the board or for the RK3528 in the github.

I would like to build my own custom image, which would allow me to load packages for my application and remove unused ones. Is there work being done for this that I’ve not found?
