Therefore they are not able to periodically kick watchdog so Espressobin enter into boot loop. This change enable CONFIG_WDT, CONFIG_WDT_ARMADA_37XX and CONFIG_CMD_WDT options which add support for U-Boot 'wdt' command. And unset new CONFIG_WATCHDOG_AUTOSTART option which cause that watchdog is not automatically started by U-Boot during init phase, like when CONFIG_WDT option is not set at all. So with this change, U-Boot on Espressobin would have working 'wdt' command which can be used from boot scripts (e.g. for enabling watchdog prior new Linux booting kernel). But default behavior of watchdog status stays unchanged, U-Boot does not start watchdog on Espressobin during its init phase.
