That all looks correct - the cache size (16kb) is different from the cacheable
range (which should normally cover the entire off-chip memory space as you have it).

You might try disabling the caches, see if that makes a difference.  You can do
this either by removing them in the MHS file and rebuilding the HW, copy the new
auto-config across, and so on.  Or, you can just manually edit the
auto-config.in file inside the kernel, run "make oldconfig clean dep all" and
rebuilt it that way.
