Upstream TF-A has basic support for RK3568 for a while, but only with the last release finally gained also cpufreq support.
The only known missing piece is enabling the ARM crypto extensions, but otherwise upstream TF-A is fully usable now. So steal and adapt Quentin's wording from tiger-rk3588 on how to use either upstream or vendor TF-A.
