+	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 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.

-	  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.

-	  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"
