config SC520_WDT
tristate "AMD Elan SC520 processor Watchdog"
depends on WATCHDOG
+ help
+ This is the driver for the hardware watchdog built in to the
+ AMD "Elan" SC520 microcomputer commonly used in embedded systems.
+ 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.
+
+ You can compile this driver directly into the kernel, or use
+ it as a module. The module will be called sc520_wdt.o.
config ALIM7101_WDT
tristate "ALi M7101 PMU Computer Watchdog"
depends on WATCHDOG
+ help
+ This is the driver for the hardware watchdog on the ALi M7101 PMU
+ as used in the x86 Cobalt servers.
+
+ 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 alim7101_wdt.o. If you want to compile it as a
+ module, say M here and read Documentation/modules.txt. Most
+ people will say N.

depends on WATCHDOG
+ help
+ This is a driver for National Semiconductor PC87307/PC97307 hardware
