Patch by Martin Krause, 8 Jun 2006 This patch supports two serial consoles on boards with a MPC5xxx CPU. The console can be switched at runtime by setting stdin, stdout and stderr to the desired serial interface (serial0 or serial1). The PSCs to be used as console port are definded by CONFIG_PSC_CONSOLE and CONFIG_PSC_CONSOLE2. See README.serial_multi for details.
