Maybe wait for linux-yocto-dev to hit > v6.19*? We used to do this for some Radxa board in the past I believe. I would prefer to add this board once support is available via any of the Yocto Project kernels. We've added boards to meta-rockchip many times in the past when support was available through linux-yocto-dev. Ideally upstream U-Boot would support it as well.
