[POWERPC] Open Firmware serial port driver
This can be used for serial ports that are connected to an OF platform bus but are not autodetected by the lecacy serial support. It will automatically take over devices that come from the legacy serial detection, which usually is only one device. In some cases, rtas may be set up to use the serial port in the firmware, which allows easier debugging before probing the serial ports. In this case, the "used-by-rtas" property must be set by the firmware. This patch also adds code to the legacy serial driver to check for this.

CPU you can make it the console by answering Y to this option.
