You have to adjust the partitioning of the devices btween secure world
(Genode) and non-secure world (Linux). This is primarily done via the
CSU (Central Security Unit) of this Freescale SoC. You can find the
relevant configuration hardcoded within:


just reset mostly all devices except the UART to belong to the
non-secure world, and set the DMA channel of the GPU (line 222) to be
unsecure. Remove the relevant patches of the Linux guest OS from this
branch (I think the last 4 commits):

and then re-build the Linux kernel and Genode scenario.
