My feeling is to leave the code alone until we have the dma  
mapping api setup to handle MURAM.  If we can't do alloc/map/free  
with the same mechanism I dont see the value in just doing 'map'.   
It just makes the code more confusing w/o any big gain.

So you don't want to see a patch where we store the physical  
address in our own data structures when the memory is mapped (or  
allocated if it's regular RAM)?

It doesn't seem like it's that big of a change.  I'd rather the code  
clearly do different things for MURAM vs system memory for ALL accesses.
