Hi Marcin,
> That's great. Was there any special trick? What was the issue?
No special trick. I just used an older U-Boot, a patched one by Marvell. It's well possible that the only real difference is in the env. This is hard to tell since i still don't know, what ubldr looks for. I could check that later. For now at least I have a starting point.

Oh no. Does that mean I have to implement a driver? That's well above my skill level.
It seems drivers/hwmon/pwm-fan.c is used, not gpio-fan. But also mvebu-gpio is very different compared to fbsd/mv/gpio.c. The Armada-385 must have Hardware-PWM on some GPIOs. Could you help to get this working?
