The serial driver subsystem does not need any extra data, so it can use `struct fdt_driver` directly. The generic fdt_serial_init() first attempts to match the chosen stdout device, and upon failure matches the first available serial device in the DT. It is a fatal error if no such device is found. This matches the behavior of fdt_driver_init_one(). Signed-off-by: Samuel Holland <samuel.holland@sifive.com> Reviewed-by: Anup Patel <anup@brainfault.org>
