* 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
