    [POWERPC] Open Firmware serial port driver · 8d38a5b2
    Arnd Bergmann 提交于
    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.
