To answer my question, yes.

Isn't there a way for the specific u-boot to be already applied? Maybe
defining a new machine which would be different just by setting the
correct dtb name and applying the sunxi u-boot?

Alternatively, it can be done on the SD card (example from Linux):

sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/mmcblk0 bs=1k seek=8 conv=sync

Nevermind, found the info about allwinner systems (somewhat outdated
because now aarch64 is supposed to work):


also found precompiled u-boot-pine64 package at

But after putting everything together the boot process hangs after
