Changes since U-Boot 1.1.4:
======================================================================
+* Update for NC650 board:
+ - Support rev1 and rev2 hardware
+ - adapt to new NAND layer
+ - add CP850 configuration based on NC650
+
* MPC5200: enable snooping of DMA transactions on XLB even if no PCI
is configured; othrwise DMA accesses aren't cache coherent which
causes for example USB to fail.
