(Forgot to reply all on the previous message, thanks for replying :)
Okay, so that seems to be mentioned on the docs and configs: 

https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/plat/allwinner.rst
https://linux-sunxi.org/Xunlong_Orange_Pi_3#Tips.2C_Tricks.2C_Caveats

I tried it using Yocto, and it generated this (redacted) make:

make -j 12 LD=aarch64-poky-linux-ld CC=aarch64-poky-linux-gcc V=1 E=0 PLAT=sun50i_h6 SUNXI_SETUP_REGULATORS=0 bl31

But still:

=> dhcp
sun8i_emac_eth_start: Timeout
