Below are debug outputs of my new RAM init code. As you can see it isn't quite working. Can this output help in finding out why?
I had to remove a bunch of debugging messages as romcc is finally running out of registers.
The code is again attached for reference.
Stick used is a 128MB PC133 DIMM in slot 0.
Thanks Keith

No. You'll have to run a diff between the old (working?) and the new code and do a binary search over the changes to find out what's causing the trouble.
