[PATCH] ppc64: add a watchdog driver for rtas
Add a watchdog using the RTAS OS surveillance service. This is
provided as a simpler alternative to rtasd. The added value
is that it works with standard watchdog client programs and
can therefore also do user space monitoring.
On BPA, rtasd is not really useful because the hardware does
not have much to report with event-scan.
The driver should also work on other platforms that support
the OS surveillance rtas calls.
