+Subject: [PATCH] common: oftree: add fixup handler for 'virtio,mmio' devices
+
+Qemu adds 'virtio,mmio' nodes to the device tree. Before passing it to the
+bootloader or the Linux kernel. This fixup handler copies these nodes to
+the new device tree.
+
+v2:
+- move from general to platform specific init
