Sorry, forgot this topic: Attached the DTB (didn't find the DTS form
around), which just gained the memory reservation we need for hypervisor
and inmates. Our U-boot is actually from the SDK (which also contains
all needed CONFIGs, like virtualization support). I also attached the
config of the currently working kernel.
