[PATCH] cpm_uart: Fix 2nd serial port on MPC8560 ADS

From: Kumar Gala
Date: Fri Aug 12 2005 - 11:32:35 EST


The 2nd serial port on the MPC8560 ADS was not being configured correctly
and thus could not be used as a console. Updated the defconfig for the
board to configure the proper SCC channel for the 2nd serial port.
