The PowerPC Book-E watchdog driver (booke_wdt.c) defines a default timeout
value in the code based on whether it's a Freescale Book-E part of not.
Instead of having hard-coded values in the driver, make it a Kconfig
option.

As newer chips gets faster, the current default values become less
appropriate, since the timeout sometimes occurs before the kernel finishes
booting.  Making the value a Kconfig option allows BSPs to configure a new
value without requiring the wdt_period command-line parameter to be set.

Register the __init and __exit functions in the PowerPC Book-E Watchdog
driver as module entry/exit functions, and modify the Kconfig entry.

Add a .release method for the PowerPC Book-E Watchdog driver, so that the
watchdog is disabled when the driver is closed.

Loosely based on original code from Jiang Yutang <b14898@freescale.com>.

This driver supports both iLO2 and iLO3, but our user-visible strings
currently only reference iLO2. Let's just call it "iLO2+" to avoid having
to update strings for each iLO generation. This driver doesn't support
iLO ASICs prior to iLO2, but that is sufficiently explained in Kconfig.

The OCTEON is a MIPS64 based SOC family with an on chip watchdog unit.

The driver is split into two source files one for the C code and one
for assembly.  Assembly is needed to handle the NMI and then print the
machine state before the reboot is triggered.

It uses the ssb subsytem to access embeded watchdog device.

Because the watchdog timeout is very short (about 2s), a soft timer is used
to increase the watchdog period.

be submitted on next linux-mips merge. Without this patch it can't
