Lite5200 and PCI1520

Hello Andrew,

This would certainly help explain some of the pain in getting it to
work.  :-/

I'm using the 2.4.25 kernel from Denx also.  The version I have is a
couple months old (trying to keep from changing too many things at once!
:-)  ),but I have also tried the top-of-CVS version to no avail.  My
ELDK version is old, as explained earlier, but I'm taking steps to
change that.

It sounds like we're working towards the same end!  I would like to
assist in some way if possible.  I am willing to believe that remapping
the PCI bus is a possible approach, although I'd like to hear the
opinion of others as well.  Where in UBOOT did you change the PCI bus
mappings?
