[PATCH] CPCI405 update (2nd version)

Hello

Please forget the patch from yesterday! I just found a small calculation
bug. Here is the corrected version:

The attached patch fixes a baudrate problem with the 400MHz version of the
PPC405GPr on the CPCI405 board.

- Added cpci405_early_serial_map (cloned from evb405ep) to generate
BASE_BAUD dynamically from the UDIV settings (configured by U-Boot).

Please apply this patch to linuxppc_2_4_devel.

Best regards,
Stefan.
