This is the whole problem, you can't do this..........

All you did was call ioremap() too early in the kernel initialization
and got 1:1 mapping.  The only valid mapping is the first one for
the IMMR space, the other ioremaps have to be done at a later time,
or preferably by the drivers themselves.  There are lots of discussions
about this in mailing list archives and FAQs.....

Thanks.
