I am trying to get linux 2.4 running on an EST SBC8260. It seems others have this board working correctly, so I must be doing something wrong. It works up to executing the rfi in turn_on_mmu, but it doesn't seem to reach start_here. I have modified linux to use the correct bd_info structure in ppcboot.h and the immr_base value. Below is some information from ppcboot.
