after some time I have found the issue. You are right, at a deeper look
I was able to see that I have made a misspelled naming of my patches.
The patches all missing the 'linux-' prefix. :)
After I have corrected this the correct address was shown while the
kernel build.

And after all the kernel is excellent booting on the STB.
