May I ask why you changed the existing configuration?
"include/configs/sbc8260.h" sets the IMMR at 0xF0000000 which works
fine with Linux. Your setting cannot work.

Yes, as many people tend to ignore FAQ's.

Similar or identical?
See
http://lists.linuxppc.org/listarcs/linuxppc-embedded/200005/msg00157.html
for an explanation why your IMMR mapping is broken and cannot work
with Linux.
And read the docs like the DULG at
http://www.denx.de/twiki/bin/view/DULG/Manual or the EMbedded PPC
HOWTO at http://www.denx.de/twiki/bin/view/PPCEmbedded/Introduction
