4 bool "Enable U-Boot watchdog reset"
6 This option enables U-Boot watchdog support where U-Boot is using
7 watchdog_reset function to service watchdog device in U-Boot. Enable
8 this option if you want to service enabled watchdog by U-Boot. Disable
9 this option if you want U-Boot to start watchdog but never service it.
14 config WATCHDOG_RESET_DISABLE
15 bool "Disable reset watchdog"
