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. NOTE: There was another patch in this series that changed some include logic in the TQM85xx.h header file. I have dropped that patch as it was screwed up and not needed.
