* Temporarily disabled John Kerl's extended MII command code because

  "miivals.h" is missing

* Patches by Mark Jonas, 13 Apr 2004:
  - Remove CS0 chip select timing setting from cpu/mpc5xxx/start.S
  - Add sync instructions to IceCube SDRAM init code
  - Move SDRAM chip constants into seperate include files
  - Unify DDR and SDR initialization code
  - Unify all IceCube (Lite5xxx) target names
