Well it is not the problem, I know that my kernel args are missing,
I'm just missing informations about how i can pass them to the kernel.
With u-boot the following command would get passed for the SD card:
setenv bootargs console=ttyO2,115200n8 vram=16M root=/dev/mmcblk0p2 rw
rootfstype=ext3 rootwait

Another question, is it possible to set these variables without
altering the Barebox files (like at run time or between configuring
and compiling).
