In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
This driver adds watchdog support for the integrated watchdog in the
SuperH processors. If you have one of these processors and wish
to have watchdog support enabled, say Y, otherwise say N.

As a side note, saying Y here will automatically boost HZ to 1000
so that the timer has a chance to clear the overflow counter. On
slower systems (such as the SH-2 and SH-3) this will likely yield
some performance issues. As such, the WDT should be avoided here
unless it is absolutely necessary.

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