Subject: * Patch by Rahul Shanbhag, 28 Jan 2004:   Fix flash
 protection/locking handling for OMAP1610 innovator board.

* Patch by Rolf Peukert, 28 Jan 2004:
  fix flash write problems on CSB226 board (write with 32 bit bus width)

* Patches by Mark Jonas, 16 Jan 2004:
  - fix rounding error when calculating baudrates for MPC5200 PSCs
  - make sure CFG_RAMBOOT and CFG_LOWBOOT are not enabled at the same
    time which is not supported
