Of course, I've shown the source located in kernel tree, not a decompiled version ...
 
I've also said something wrong : I've a local patch not included in Armbian tree :

You can use that patch if you are doing you own build ...
... or you can tweak your decompile DT to make sure that USB nodes are matching that, or use my own DTB attached, of course after backing up yours first ...
 
sun8i-h3-orangepi-lite.dtb

BTW, recompiling /boot/boot.scr is only needed after changes to /boot/boot.cmd. Changes to /boot/armbianEnv.txt doesn't requires recompiling.

UUID in /boot/armbianEnv.txt ? Yes ! on the line "rootdev=" which is passed as kernel argument.

From what I understood, Mainline has different folder hierarchy.
Check those :
/sys/power/axp_pmu/ac
/sys/power/axp_pmu/battery
/sys/power/axp_pmu/vbus
 

Starting to do Bare Metal programming isn't a easy task ...
You will need to learn a tons of things, you need to start here : http://linux-sunxi.org/A20
Then here : http://linux-sunxi.org/EGON and http://linux-sunxi.org/BROM
Good luck !

Some people faced similar behavior several months ago, but they figured that either doing "lssub -vvv" and/or plugging another USB devices first would workaround the issue, USB doing some kind of waking up.

Effectively, you seems confused about GPIO pin name.
It should be simple as "param_w1_pin=PD14" for example.

You've forgot to define "param_spidev_spi_bus" which is mandatory ...

There is no "special" boot configuration since U-Boot rely on the 3 symbolic links which point to proper Image/uInitrd/dts .
It is possible, but then you have to manually install every things and create the symbolic links as well as creating uInitrd using "mkimage".
It is much more easier to use Armbian DEBs ...

After hours of investigation, and after having figured out that SPI for H6 wasn't working since 5.7.x, I've found why : missing SPI pins in DT ...
