wdt: sunxi: Move restart code to the watchdog driver

2014-08-05T20:43:37+00:00

Most of the watchdog code is duplicated between the machine restart code and
the watchdog driver. Add the restart hook to the watchdog driver, to be able to
remove it from the machine code eventually.

watchdog: imx2_wdt: adds big endianness support.

2014-08-05T20:43:11+00:00

This watchdog driver will be working on IMX2+, Vybrid, LS1, LS2+
platforms, and will be in different endianness mode in those SoCs:

    SoCs       WDT endian mode
------------------------------------
    IMX2+           LE

MIPS: OCTEON: watchdog: don't jump to bootloader without entry address

2014-08-01T22:06:42+00:00

If CONFIG_HOTPLUG_CPU is set, the driver thinks bootloader entry
address is configured and we should jump there. However, this is
not necessarily true if the kernel is booted on a system
with older/incompatible bootloader.

Add dynamic checks for the bootloader entry address.

The help text for DIAG288_WATCHDOG in drivers/watchdog/Kconfig
still mentioned the misleading old module name vmwatchdog.
This patch changes that to the correct new name diag288_wdt.
