This series of patches makes Xen pass a (somewhat) valid device tree to dom0. The device tree for dom0 is the same as the one supplied to Xen except the memory and chosen nodes are adjusted appropriately. We don''t yet make use of the device tree to map MMIO regions or setup interrupts for the guest and we still include the UART used for Xen''s console. Note that loading Linux
