Sigh, didn't notice this was the external list, so I'll elaborate.  We  
never want to create a non-IPROT entry, as we don't have a TLB miss  
handler that will replace entries that have been invalidated.  This  
will be especially important if we ever run U-Boot inside a virtual  
machine.  And yes, this means that the current TLB0 usage should go  
away as well.
