dt: Add -machine dumpdtb option to dump the current dtb
Now that we are dynamically creating the dtb, it's really useful to be able to dump the created blob for debugging. This patch implements a -machine dumpdtb=<file> option for e500 that dumps the dtb exactly in the form the guest would get it to disk. It can then be analyzed by dtc to get information about the guest configuration. Signed-off-by: Alexander Graf <agraf@suse.de>
