That code is not capable of testing more than 2GB of RAM.  It assumes
that memory has already been initialized, but on PowerPC parts, we
only ever map 2GB of DDR.  We need a memory test that covers all of
DDR, but that requries PowerPC-specific code to create sliding TLB
windows during the memory test.
