Ok, I get it now.  I'm supposed to call get_ram_size() on each DIMM I
locate.  That's going to be complicated because we don't have any TLBs set
up when we do that.

And what if we have a 4GB DIMM?  Because virtual addresses are still
32-bits, we would need to change get_ram_size() to modify a temporary TLB
while it's reading/writing memory.  So we'd need to have an e300 version of
get_ram_size(), an e500 version, an e600 version, and so on.

So I have a question: are you still going to require me to use
get_ram_size() in my P1022DS board patch?
