Hello list,
here I am (again!) ;-)

Now I have downloaded the linux 4.5-rc6 (because I would like to use 
etnaviv gpu driver), configured as imx_v6_v7_defconfig, added the 
DEBUG_LL stuff for uart3 and added in the Makefile for dts my dts (more 
or less like Barebox one [in attachment] ), but here is what I get 
(compiling the kernel with DEBUG_LL for uart3):

It looks like something were wrong with devicetree or other machine 
identifier stuff...


Where is the issue???
