With the teres-1 [1] laptop we have a first arm64 device we could use as end-users. Much work to run mainline kernel + u-boot was done already. But power consumption of the laptop is not optimal (~2 hours of battery life time).

The idea is to support cpufreq for the A64 SoC upstream, which would enable the teres-1, pine64 and pinebook to run more power efficient. up to now it seems nobody is working on the driver [2].
