Leon, thank you!
You practically made everything clear now!
Please, just a few more questions below, before I put my hands
on the keyboard :)
You are welcome. I am glad that I was able to help.
PS I read all the sunxi docs but now all the pieces fall into one.

1. U-boot version for Tizen?
Is there a special version of U-boot for Tizen which is located
somewhere in
the Tizen source tree?
Or will the Sunxi's U-boot version will be enough to boot Tizen?
It is recommended to use the linux-sunxi fork of Das U-Boot:
https://github.com/linux-sunxi/u-boot-sunxi [1]
There is a version of U-Boot for Tizen but so far it is targeting
Odroid and the Tizen developer devices trats (RD-210) and trats2
(PR-PQ) only. Information about U-Boot for Tizen has been revealed
during LinuxCon Europe:
http://sched.co/1xmhyG4 [2]
In another talk during the same event Hans de Goede revealed the
status of U-Boot for Sunxi devices. As far as I remember he
announced that the mainline U-Boot is (or will be soon) compatible
with A10 & A20. More details regarding his presentation are
available at:
http://sched.co/1xmrE9N [3]
2. Tizen kernel source?
As far as I understood (and I actuallty installed it myself) the
freshest
version of the Sunxi's kernel for A20 is 3.4. There are no
kernels above 3.4
that will work with all the Cubieboard 2's hardware features.
Is this also true for Tizen? Or there is some newer kernel
version somewhere
in the Tizen's source tree?
Tizen:Common and IVI require kernel 3.14 LTSI but at the moment the
latest stable version of the kernel for Sunxi devices is 3.4. There
are ongoing initiatives among the linux-sunxi community to support
mainline kernel on A20 but a lot of things are still not working
properly.
1. Where exactly this 3.14 LTSi kernel located in the Tizen source
tree?
Or is it just a mainline kernel with specific Tizen defconfig?
Yes, it is the mainline kernel.
2. Which exactly features do not work in Tizen on the 3.14 LTSi
kernel?
As far as I know Tizen:Common and the profiles based on it such as IVI
are supposed to be fully complaint with 3.14 LTSi kernel so everything
should be working :)
The major issues that you will face with Tizen:Common (or IVI) &
linux-sunxi 3.4 on A20 devices are the support of smack options as well
as the Mali DDK for Wayland.
Best regards,
Leon
