My earlier patches changed the way this was done and broke this. I've created a new function, clear_ddr_tlbs(), so that there is now a setup_ddr_tlbs() and a matching clear_ddr_tlbs() that boards can use if they need to temporarily set up a TLB entry for this purpose. The tqm85xx ddr init code now uses this and the board is able to boot. There is also a cleanup patch to the TQM header file to make it easier to read - I added code that is dependent on this so it's included in this series.
