config WATCHDOG
bool "Enable U-Boot watchdog reset"
depends on !HW_WATCHDOG
help
This option enables U-Boot watchdog support where U-Boot is using
watchdog_reset function to service watchdog device in U-Boot. Enable
this option if you want to service enabled watchdog by U-Boot. Disable
this option if you want U-Boot to start watchdog but never service it.
config WATCHDOG_AUTOSTART

depends on WDT
default n if ARCH_SUNXI
default y
help
Automatically start watchdog timer and start servicing it during
init phase. Enabled by default. Disable this option if you want
to compile U-Boot with CONFIG_WDT support but do not want to
activate watchdog, like when CONFIG_WDT option is disabled. You
would be able to start watchdog manually by 'wdt' command. Useful
when you want to have support for 'wdt' command but do not want
to have watchdog enabled by default.
