I think it would be trivial to modify this code to look for a 
Scott-style muram node.  Heck, it could be modified to look for both, 
and so we'll maintain compatibility.

I was thinking of just removing the muram code from qe_lib, and having 
it use the code in cpm_common.c.

BTW, searching the entire device tree for a node with the name 
"data-only", regardless of context, seems a bit insane to me.
