Space.  But you already knew that. ;-)

Use the latest version of "dtc" with the -S <space> parameter and you 
will also want to add reserve map entries with the -R <n> parameter or 
bootm will fail when it tries to add the initrd memory region to the 
reserved map.

This following makefile works well for me (WARNING: it is whitespace 
damaged because I cut & pasted it - replace the spaces with tabs or make 
will barf).
