If the path we are trying to print doesn't exist see if it matches an aliases. We don't do anything fancy at this point, but just strip the leading '/' if it exists and see if we have an exact match to an alias.
In the future we could try and prefix matching so the alias could be used as a shorter path reference.

Cool and useful too. Out of curiousity, does "real" Open Firmware do this sort of thing with aliases?
One reservation I have (which may disappear if the answer to the previous question is "yes"), it automatically and silently dereferences the /aliases/X node when asked to display /X or X (but only if /X doesn't exist in the dtb). This is not an obvious behavior since X isn't real.
Should we have a different display syntax to force the dereference of an alias X? Assuming "*" is a good choice, this would change the behavior fdt print *ethernet0 to dereference /aliases/ethernet0 and print out /soc8360@e0000000/.../enet0 (or whatever).
Thanks, gvb
