-config WATCHDOG
-	bool "Watchdog Timer Support"
-	---help---
-	  If you say Y here (and to one of the following options) and create a
-	  character special file /dev/watchdog with major number 10 and minor
-	  number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
-	  subsequently opening the file and then failing to write to it for
-	  longer than 1 minute will result in rebooting the machine. This
-	  could be useful for a networked machine that needs to come back
-	  online as fast as possible after a lock-up. There's both a watchdog
-	  implementation entirely in software (which can sometimes fail to
-	  reboot the machine) and a driver for hardware watchdog boards, which
-	  are more robust and can also keep track of the temperature inside
-	  your computer. For details, read <file:Documentation/watchdog.txt>
-	  in the kernel source.
-
-	  The watchdog is usually used together with the watchdog daemon
-	  which is available from
-	  <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
-	  also monitor NFS connections and can reboot the machine when the process
-	  table is full.
-
-	  If unsure, say N.
-
-config WATCHDOG_NOWAYOUT
-	bool "Disable watchdog shutdown on close"
-	depends on WATCHDOG
-	help
-	  The default watchdog behaviour (which you get if you say N here) is
-	  to stop the timer if the process managing it closes the file
-	  /dev/watchdog. It's always remotely possible that this process might
-	  get killed. If you say Y here, the watchdog cannot be stopped once
-	  it has been started.
-
-config SOFT_WATCHDOG
-	tristate "Software watchdog"
-	depends on WATCHDOG
-	help
-	  A software monitoring watchdog. This will fail to reboot your system
-	  from some situations that the hardware watchdog will recover
-	  from. Equally it's a lot cheaper to install.
-
-	  This driver is also available as a module ( = code which can be
-	  inserted in and removed from the running kernel whenever you want).
-	  If you want to compile it as a module, say M here and read
-	  <file:Documentation/modules.txt>. The module will be called

-	tristate "WDT Watchdog timer"
-	depends on WATCHDOG
-	---help---
-	  If you have a WDT500P or WDT501P watchdog board, say Y here,
-	  otherwise N. It is not possible to probe for this board, which means
-	  that you have to inform the kernel about the IO port and IRQ using

-config I810_TCO

-	---help---
-	  Hardware driver for the TCO timer built into the Intel i810 and i815
-	  chipset family.  The TCO (Total Cost of Ownership) timer is a
-	  watchdog timer that will reboot the machine after its second
-	  expiration. The expiration time can be configured by commandline
-	  argument "i810_margin=<n>" where <n> is the counter initial value.
-	  It is decremented every 0.6 secs, the default is 50 which gives a
-	  timeout of 30 seconds and one minute until reset.
-
-	  On some motherboards the driver may fail to reset the chipset's
-	  NO_REBOOT flag which prevents the watchdog from rebooting the
-	  machine. If this is the case you will get a kernel message like
-	  "i810tco init: failed to reset NO_REBOOT flag".
-
-	  If you want to compile this as a module, say M and read

-	help
-	  This driver can be used with the watchdog timer found on some
-	  single board computers, namely the 6010 PII based computer.
-	  It may well work with other cards.  It reads port 0x443 to enable
-	  and re-set the watchdog timer, and reads port 0x45 to disable
-	  the watchdog.  If you have a card that behave in similar ways,
-	  you can probably make this driver work with your card as well.
-
-	  You can compile this driver directly into the kernel, or use

+	  and re-set the watchdog timer, and reads port 0x45 to disable
+	  the watchdog.  If you have a card that behave in similar ways,
+	  you can probably make this driver work with your card as well.

+	  it as a module.  The module will be called sbc60xxwdt.o.

+config W83877F_WDT

+	depends on WATCHDOG
+	---help---
+	  This is the driver for the hardware watchdog on the W83877F chipset
+	  as used in EMACS PC-104 motherboards (and likely others).  This
+	  watchdog simply watches your kernel to make sure it doesn't freeze,
+	  and if it does, it reboots your computer after a certain amount of
+	  time.
+
+	  This driver is also available as a module ( = code which can be
+	  inserted in and removed from the running kernel whenever you want).
+	  The module is called mixcomwd.o.  If you want to compile it as a
+	  module, say M here and read <file:Documentation/modules.txt>.  Most
+	  people will say N.
+
+config MACHZ_WDT
+	tristate "ZF MachZ Watchdog"
+	depends on WATCHDOG
+	---help---
+	  If you are using a ZF Micro MachZ processor, say Y here, otherwise
+	  N.  This is the driver for the watchdog timer builtin on that
+	  processor using ZF-Logic interface.  This watchdog simply watches
+	  your kernel to make sure it doesn't freeze, and if it does, it
+	  reboots your computer after a certain amount of time.
+
+	  This driver is also available as a module ( = code which can be
+	  inserted in and removed from the running kernel whenever you want).
