> 1) u-boot
> This is how I built u-boot:
> git clone git://git.denx.de/u-boot.git
> cd u-boot
> git checkout v2017.05
> # apply patch so it can be built on FreeBSD (tested on FreeBSD 11.1-BETA1)

> gmake ARCH=arm CROSS_COMPILE=arm-none-eabi- orangepi_zero_defconfig
> gmake -j4 ARCH=arm CROSS_COMPILE=arm-none-eabi-
> dd if=u-boot-sunxi-with-spl.bin conv=notrunc,sync of=/dev/mmcsd0 bs=1024
> seek=8

> In the u-boot prompt:
>   fatload mmc 0 0x42000000 ubldr.bin
>   setenv fdtfile sun8i-h3-orangepi-one.dtb
>   go 0x4200000
> ubldr will work as expected, but kernel will hang at the start.

> 2) newer DTS/DTB
> If I use sun8i-h3-orangepi-one.dtb from FreeBSD source tree then the board
> will boot fine, but I don't have network.
> I can also boot normally if the dtb file is rebuilt manually:
>   cd /usr/src/sys/gnu/dts/arm
>   cpp -P -x assembler-with-cpp -I /usr/src/sys/gnu/dts/include -include
> sun8i-h3-orangepi-plus.dts /dev/null | dtc -O dtb -o ./sun8i-h3-rebuilt.dtb
>   ls -lh sun8i-h3-rebuilt.dtb
>   -rw-r--r--  1 root  wheel    15K Jun 24 13:02 sun8i-h3-rebuilt.dtb
> But, if dtb files from Armbian (Linux 4.11) are used, kernel will hang:
>   Using DTB from loaded file
> 'boot/dtb-4.11.3-sun8i/sun8i-h2-plus-orangepi-zero.dtb'.
>   Kernel entry at 0x42200100...
>   Kernel args: -v
> The same file boots Linux without problems.
> 
> I don't know why newer dtb files won't work because there is no output on
> serial console.
> Any ideas how to make it work?
