My panic seems related to memory regions in device tree.  I am appended
my DTB to the kernel zImage.
How does the memory assigned by XEN for the guest domain get inserted
into the device tree?
Does Hypervisor or the toolchain manipulate the appended DTB and modify
the hypervisor node's reg and irq properties? What about the memory node?

Thanks,
Eric
