+ tristate "IOP Watchdog"
+ depends on WATCHDOG && PLAT_IOP
+ select WATCHDOG_NOWAYOUT if (ARCH_IOP32X || ARCH_IOP33X)
+ help
+ Say Y here if to include support for the watchdog timer
+ in the Intel IOP3XX & IOP13XX I/O Processors. This driver can
+ be built as a module by choosing M. The module will
+ be called iop_wdt.
+
+ Note: The IOP13XX watchdog does an Internal Bus Reset which will
+ affect both cores and the peripherals of the IOP. The ATU-X
+ and/or ATUe configuration registers will remain intact, but if
+ operating as an Root Complex and/or Central Resource, the PCI-X
+ and/or PCIe busses will also be reset. THIS IS A VERY BIG HAMMER.
