config SERIAL_8250

        tristate "8250/16550 and compatible serial support"

        select SERIAL_CORE

        ---help---

          This selects whether you want to include the driver for the standard

          serial ports.  The standard answer is Y.  People who might say N

          here are those that are setting up dedicated Ethernet WWW/FTP

          servers, or users that have one of the various bus mice instead of a

          serial mouse and don't intend to use their machine's standard serial

          port for anything.  (Note that the Cyclades and Stallion multi

          serial port drivers do not need this driver built in for them to

          work.)

          To compile this driver as a module, choose M here: the

          module will be called 8250.

          [WARNING: Do not compile this driver as a module if you are using

          non-standard serial ports, since the configuration information will

          be lost when the driver is unloaded.  This limitation may be lifted

          in the future.]

          BTW1: If you have a mouseman serial mouse which is not recognized by

          the X window system, try running gpm first.

          BTW2: If you intend to use a software modem (also called Winmodem)

          under Linux, forget it.  These modems are crippled and require

          proprietary drivers which are only available under Windows.

          Most people will say Y or M here, so that they can use serial mice,

          modems and similar devices connecting to the standard serial ports.

config DE2_70_CONSOLE

        select SERIAL_CORE_CONSOLE

        help

config SERIAL_8250_CONSOLE

        bool "Console on 8250/16550 and compatible serial port"

        depends on SERIAL_8250=y

        select SERIAL_CORE_CONSOLE

        ---help---

          If you say Y here, it will be possible to use a serial port as the

          system console (the system console is the device which receives all

          kernel messages and warnings and which allows logins in single user

          mode). This could be useful if some terminal or printer is connected

          to that serial port.

          Even if you say Y here, the currently visible virtual console

          (/dev/tty0) will still be used as the system console by default, but

          you can alter that using a kernel command line option such as

          "console=ttyS1". (Try "man bootparam" or see the documentation of

          your boot loader (grub or lilo or loadlin) about how to pass options

          to the kernel at boot time.)

          If you don't have a VGA card installed and you say Y here, the

          kernel will automatically use the first serial line, /dev/ttyS0, as

          system console.

          You can set that using a kernel command line option such as

          "console=uart8250,io,0x3f8,9600n8"

          "console=uart8250,mmio,0xff5e0000,115200n8".

          and it will switch to normal serial console when the corresponding

          port is ready.

          "earlycon=uart8250,io,0x3f8,9600n8"

          "earlycon=uart8250,mmio,0xff5e0000,115200n8".

          it will not only setup early console.

          If unsure, say N.

          Note that the answer to this question won't directly affect the
