Hi,

I managed to boot FreeBSD on the Rockchip RK3399 SoC (Pine64 ROCKPro64=20
board):

https://gist.github.com/myfreeweb/5f5b9e56f9a0fd1d63a46c34886f5ad1

As with the ROCK64, boot is over the network. To boot, dd ayufan's=20
ubuntu image onto an sdcard and Ctrl-C the linux boot on the kernel=20
selection screen. U-Boot on SPI flash is not available yet.

Unfortunately, performance is very disappointing =97 I think the big=20
cluster's default frequency is very low.
(Everything runs faster if cpuset to the LITTLE cores.)

Looks like we'll need a driver for the "rockchip,rk808" PMIC to make=20
cpufreq_dt work=85
Also my attempt at the clock driver is very incomplete ;)
