The Linux kernel configuration item CONFIG_SH_WDT has multiple definitions:
drivers/watchdog/KconfigThe configuration item CONFIG_SH_WDT:
CONFIG_SUPERH && ( CONFIG_CPU_SH3 || CONFIG_CPU_SH4 || CONFIG_COMPILE_TEST )shwdt, shwdt, shwdtThis 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.

arch/sh/KconfigThe configuration item CONFIG_SH_WDT:
CONFIG_WATCHDOGshwdt, shwdt, shwdtThis driver adds watchdog support for the integrated watchdog in the SuperH 3 and 4 processors. If you have one of these processors, say Y, otherwise say N.
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 shwdt. If you want to compile it as a module, say M here and read Documentation/modules.txt.
