We already have:

| commit f59f5e86256f82daf4af3bf1922805592b780613
| Author: Sascha Hauer <s.hauer at pengutronix.de>
| Date:   Sat Oct 6 19:51:47 2012 +0200
| 
|     of: find and register memory during probe
|     
|     This automatically registers the memory nodes in the devicetree.

I suspect there is something missing since this commit checks for the
'device_type' property, but does not actually test if it matches
'memory'. So there might be some work necessary, but this code already
handles 64bit cells correctly, at least it tries to ;)
