[U-Boot] [PATCH v2 0/2]: Watchdog support from the command line

Hi!

These two patches add a generic watchdog CLI command and a driver for the watchdog on Marvell Kirkwood that uses it.

The command usage is

watchdog - Watchdog commands

Usage: watchdog <timeout> - start the watchdog with `timeout' seconds timeout

ChangeLog: v2: Adapt according to comments from Prafulla and Wolfgang * Passing zero as timeout is invalid (Prafulla) * Add return value from watchdog_enable(), negative means failure (Prafulla, Wolfgang) * Remove watchdog_disable() (Wolfgang) * Use weak default function for watchdog_enable() (Wolfgang) * Provide friendly and helpful printouts when invalid parameters are passed to the CLI command
