CONFIG_IEEE1394
  IEEE 1394 describes a high performance serial bus, which is also
  known as FireWire(tm) or i.Link(tm) and is used for connecting all
  sorts of devices (most notably digital video cameras) to your
  computer.

  If you have FireWire hardware and want to use it, say Y here.  This
  is the core support only, you will also need to select a driver for
  your IEEE 1394 adapter.

  If you want to compile this as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>.  The module
  will be called ieee1394.o.

CONFIG_IEEE1394_PCILYNX
  Say Y here if you have an IEEE-1394 controller with the Texas
  Instruments PCILynx chip.  Note: this driver is written for revision
  2 of this chip and may not work with revision 0.

  If you want to compile this as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>.  The module
  will be called pcilynx.o.

CONFIG_IEEE1394_PCILYNX_LOCALRAM
  This option makes the PCILynx driver use local RAM available on some
  PCILynx setups for Packet Control Lists. Local RAM is random access
  memory which resides on the PCILynx board as opposed to on your
  computer's motherboard. Local RAM may speed up command processing
  because no PCI transfers are necessary during use of the Packet
  Control Lists.

  Note that there are no known PCILynx systems providing local RAM
  except for the evaluation boards by Texas Instruments and that the
  PCILynx does not reliably report missing RAM. This means that it is
  dangerous to say Y here if you are not absolutely sure that your
  board provides 64KB of local RAM.

  If unsure, say N.

CONFIG_IEEE1394_PCILYNX_PORTS
  This option enables driver code to access the RAM, ROM and AUX ports
  of the PCILynx through character devices in /dev.  If you don't know
  what this is about then you won't need it.

  If unsure, say N.

CONFIG_IEEE1394_OHCI1394
  Enable this driver if you have an IEEE 1394 controller based on the
  OHCI-1394 specification. The current driver is only tested with OHCI
  chipsets made by Texas Instruments and NEC. Most third-party vendors
  use one of these chipsets.  It should work with any OHCI-1394
  compliant card, however.

  If you want to compile this as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>.  The module
  will be called ohci1394.o.

CONFIG_IEEE1394_VIDEO1394
  This option enables video device usage for OHCI-1394 cards.  Enable
  this option only if you have an IEEE 1394 video device connected to
  an OHCI-1394 card.

CONFIG_IEEE1394_DV1394
  This driver allows you to transmit and receive DV (digital video)
  streams on an OHCI-1394 card using a simple frame-oriented
  interface.

  The user-space API for dv1394 is documented in dv1394.h.

  If you want to compile this as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>.  The module
  will be called dv1394.o.

CONFIG_IEEE1394_SBP2
  This option enables you to use SBP-2 devices connected to your IEEE
  1394 bus.  SBP-2 devices include harddrives and DVD devices.

CONFIG_IEEE1394_RAWIO
  Say Y here if you want support for the raw device. This is generally
  a good idea, so you should say Y here. The raw device enables
  direct communication of user programs with the IEEE 1394 bus and
  thus with the attached peripherals.

  If you want to compile this as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>.  The module
  will be called raw1394.o.

CONFIG_IEEE1394_ETH1394
  Extremely Experimental! This driver is a Linux specific way to use your
  IEEE1394 Host as an Ethernet type device. This is _NOT_ IP1394.

CONFIG_IEEE1394_AMDTP
  This option enables the Audio & Music Data Transmission Protocol
  (IEC61883-6) driver, which implements audio transmission over
  IEEE1394.

  The userspace interface is documented in amdtp.h.

  If you want to compile this as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>.  The module
  will be called amdtp.o.

CONFIG_IEEE1394_CMP
  This option enables the Connection Management Procedures
  (IEC61883-1) driver, which implements input and output plugs.

  If you want to compile this as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>.  The module
  will be called amdtp.o.

CONFIG_IEEE1394_VERBOSEDEBUG
  If you say Y here, you will get very verbose debugging logs from the
  subsystem which includes a dump of the header of every sent and
  received packet.  This can amount to a high amount of data collected
  in a very short time which is usually also saved to disk by the
  system logging daemons.

  Say Y if you really want or need the debugging output, everyone else
  says N.
