Dear Becky Bruce,

We need a TLB entry to call get_ram_size(); the common code doesn't create one until *after* fixed_sdram() has determined the size. So we set up tlbs for the max possible size and tear them down once we're done with get_ram_size(); the common 85xx code will then set up a final set of tlb entries for the *actual* detected size of ddr.
This prevents us from having TLB entries that are larger than DDR sitting around for very long, which is not a recommended scenario.
