Buildroot for Radxa zero 3 w

HI,
Has anyone managed to compile Buildroot on Zero 3W, I have config files, patches etc. or something else to get started.
I have something running on buildroot raspi zero w, and I would like to use radxa zero 3W, but if buildroot isn’t supported, I won’t be able to port the software from the raspberry project.

Thanks for anyone with any useful info
