The superio needs 0x87 sent twice to 0x3f0 to enable extended function (power-on strapping). Although this is already done in superio.c, it's not being done when w83977tf_early_serial.c is executed. As such, no console_init() without it. Signed-off-by: Roger Zauner <roger@eskimo.com> Acked-by: Uwe Hermann <uwe@hermann-uwe.de>
