I also needed another serial port. I have made register_serial and 
unregister_serial static in au1x00-serial.c so they will shadow the 
external functions with the same name and will not be exported and 
changed the name from ttyS to ttySA to avoid conflicts with serial.c.
After that it worked for me.

static struct console sercons = {
        .name           = "ttySA",
        .write          = serial_console_write,
        .device         = serial_console_device,
        .setup          = serial_console_setup,
        .flags          = CON_PRINTBUFFER,
        .index          = -1,
};
