A property in a DTS file can use that to say
the property should have a value, but it will
be filled in by the bootwrapper instead (memory
address/size, or network MAC address, for
instance).  Presumably the kernel parser would
complain when it sees the this-is-still-undefined
marker.

The original proposal specified the length of
the property value IIRC, but that isn't necessary
anymore.
