No, u-boot should fill in the same stuff.  It may require the empty
fields to be there, though (it definitely requires it if you're using
the old, non-libfdt code -- if you are, you should also remove the 
/chosen node, or else you'll get two of them).

In the bootwrapper case, it's the code in cuboot-pq2.c and devtree.c. 
In the no-bootwrapper case, it's u-boot.
