Current versions "require" the chosen node.  u-boot will provide it,  
though, so you don't need to add it unless your u-boot doesn't  
provide it (This would mean you'd need to boot with a boot wrapper.   
Or get a newer u-boot ;) ).  In order to avoid the error being fatal,  
pass "-f" to the dtc.  I believe it's on the communal "TODO" list for  
the dtc.  But, given the choice between modifying the code, and  
adding "-f" to the command line, most people have chosen the two- 
character option.
