Here's a repost of my Xilinx ML300 and ML403 patches with a few
cleanups, a bit of patch reordering, and rebased to 2.6.15.

Changes:
 - Remove xparameters.h as a dependancy to most of the kernel tree
 - Rework Virtex-II Pro support to be generic for Virtex-4 also
 - Move serial drivers from the OCP bus to the platform bus
 - Modify ML300 to use platform bus
 - Add support for ML403
 - Add ML300 & ML403 defconfigs

I've tested on an ML403
Can someone test on an ML300?  (I no longer have one)

Cheers,
g.
