How can this work ? Memory is parsed from early_init_devtree() which is
called before the platform probe() routines which is the one that sets
FW_FEATURE_PS3_LV1... 

It's really annoying that they didn't get their device-tree right in the
first place. They should put the RMO in there and nothing else I
suppose.
