* 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
