looking for YP-supported Rockchip RK3588-based eval board

  (caveat: i have *no* experience with rockchip processors so i am
entirely at the mercy of people who want to make recommendations.)

  a friend wants me to advise on a good choice for a RK3588-based
evaluation board, and has already purchased a banana pi bpi-w3:

  that looks like a decent and fairly powerful baord, but i notice
that the banana pi is not a supported MACHINE in meta-rockchip:

  https://git.yoctoproject.org/meta-rockchip/tree/conf/machine

so can anyone suggest something equivalent in terms of pure horsepower
that would be equivalent and has solid YP support? i am totally open
to good advice.
