Yeah, but LKML has some of the patches there in review, for example:
* http://lkml.iu.edu/hypermail/linux/kernel/2001.1/01899.html (already accepted)
* https://patchwork.kernel.org/patch/11325531/ (pending changes)
[...]
* https://www.spinics.net/lists/kernel/msg3367972.html (pending changes)
So all in all I think the Pinebook Pro will eventually work with the vanilla
kernel.

It might make sense to find out why this is necessary.
https://lists.denx.de/pipermail/u-boot/2014-January/171682.html describes that
it
should be possible to set up u-boot environment variables (in uEnv.txt) to make
it find the correct FDT file anyway. If none is set up, it automatically
generates
the file name to use using $soc and $board. But that's for PXE booting
(booting empty machine via network)--not sure where the normal case is in
U-Boot,
if any. U-Boot sometimes has some weird blind spots like that.
Also, https://lists.denx.de/pipermail/u-boot/2016-May/254703.html kinda
sounds like they dont support subdirs. Wanna try adding "/rockchip" to the
end of FDTDIR in extlinux.conf ?
Also, what's the value of CONFIG_[DEFAULT_]DEVICE_TREE in your u-boot
configuration?

I'm all for wip-pinebook-pro @ savannah, especially before losing a now-working
version by hacking further on it. Been there done that :)
If you want we can collaborate in the next days on finding the cause of
the weird FDT problem.

Sure!
As a general remark, make-u-boot-package was not public because
I didn't want to commit to its interface yet.
I think we don't need to export it even now. (We can if we have to)
