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):

Please check your kernel config and/or bootloader.
It looks like something were wrong with devicetree or other machine
identifier stuff...
Where is the issue???
