config DEVKMEM
	bool "/dev/kmem virtual device support"
	default y
	help
	  Say Y here if you want to support the /dev/kmem device. The
	  /dev/kmem device is rarely used, but can be used for certain
	  kind of kernel debugging operations.
	  When in doubt, say "N".

config BFIN_JTAG_COMM
	tristate "Blackfin JTAG Communication"
	depends on BLACKFIN
	help
	  Add support for emulating a TTY device over the Blackfin JTAG.

	  To compile this driver as a module, choose M here: the
	  module will be called bfin_jtag_comm.

config BFIN_JTAG_COMM_CONSOLE
	bool "Console on Blackfin JTAG"
	depends on BFIN_JTAG_COMM=y

config SERIAL_NONSTANDARD
	bool "Non-standard serial port support"
	depends on HAS_IOMEM
	---help---
	  Say Y here if you have any non-standard serial boards -- boards
	  which aren't supported using the standard "dumb" serial driver.
	  This includes intelligent serial boards such as Cyclades,
	  Digiboards, etc. These are usually used for systems that need many
	  serial ports because they serve many terminals or dial-in
	  connections.

	  Note that the answer to this question won't directly affect the
	  kernel: saying N will just cause the configurator to skip all
	  the questions about non-standard serial boards.

	  Most people can say N here.

config COMPUTONE
	tristate "Computone IntelliPort Plus serial support"
	depends on SERIAL_NONSTANDARD && (ISA || EISA || PCI)
	---help---
	  This driver supports the entire family of Intelliport II/Plus
	  controllers with the exception of the MicroChannel controllers and
	  products previous to the Intelliport II. These are multiport cards,
	  which give you many serial ports. You would need something like this
	  to connect more than two modems to your Linux box, for instance in
	  order to become a dial-in server. If you have a card like that, say
	  Y here and read <file:Documentation/serial/computone.txt>.

	  To compile this driver as module, choose M here: the
	  module will be called ip2.

config ROCKETPORT
	tristate "Comtrol RocketPort support"
	depends on SERIAL_NONSTANDARD && (ISA || EISA || PCI)
	help
	  This driver supports Comtrol RocketPort and RocketModem PCI boards.   
          These boards provide 2, 4, 8, 16, or 32 high-speed serial ports or
          modems.  For information about the RocketPort/RocketModem  boards
          and this driver read <file:Documentation/serial/rocket.txt>.

	  To compile this driver as a module, choose M here: the
	  module will be called rocket.

	  If you want to compile this driver into the kernel, say Y here.  If
          you don't have a Comtrol RocketPort/RocketModem card installed, say N.

config CYCLADES
	tristate "Cyclades async mux support"
	depends on SERIAL_NONSTANDARD && (PCI || ISA)
	select FW_LOADER
	---help---
	  This driver supports Cyclades Z and Y multiserial boards.
	  You would need something like this to connect more than two modems to
	  your Linux box, for instance in order to become a dial-in server.

	  For information about the Cyclades-Z card, read
	  <file:Documentation/serial/README.cycladesZ>.

	  To compile this driver as a module, choose M here: the
	  module will be called cyclades.

	  If you haven't heard about it, it's safe to say N.

config CYZ_INTR
	bool "Cyclades-Z interrupt mode operation (EXPERIMENTAL)"
	depends on EXPERIMENTAL && CYCLADES
	help
	  The Cyclades-Z family of multiport cards allows 2 (two) driver op
	  modes: polling and interrupt. In polling mode, the driver will check
	  the status of the Cyclades-Z ports every certain amount of time
	  (which is called polling cycle and is configurable). In interrupt
	  mode, it will use an interrupt line (IRQ) in order to check the
	  status of the Cyclades-Z ports. The default op mode is polling. If
	  unsure, say N.

config DIGIEPCA
	tristate "Digiboard Intelligent Async Support"
	depends on SERIAL_NONSTANDARD && (ISA || EISA || PCI)
	---help---
	  This is a driver for Digi International's Xx, Xeve, and Xem series
	  of cards which provide multiple serial ports. You would need
	  something like this to connect more than two modems to your Linux
	  box, for instance in order to become a dial-in server. This driver
	  supports the original PC (ISA) boards as well as PCI, and EISA. If
	  you have a card like this, say Y here and read the file
	  <file:Documentation/serial/digiepca.txt>.

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