IOP Watchdog

modulename: iop_wdt.ko

configname: CONFIG_IOP_WATCHDOG

Linux Kernel Configuration
└─>Device Drivers
└─>Watchdog Timer Support
└─>IOP Watchdog
In linux kernel since version 2.6.24 (release Date: 2008-01-24)  
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.
