Disabling watchdog isn't possible in hardware, thus users should either only enable it before boot or have the poller take care of feeding it.

2018-11-16	475eac0 Browse files » ARM: i.MX: When SRSR shows wdog then lookup reset source in wdog ... On i.MX6 when the watchdog has resetted the system then the SRSR register correctly shows that the watchdog has resetted the system. This is not the desired result though, a "reset" in barebox or "reboot" in Linux should result in "RST" as reset source. So instead of making the SRSR register value overwrite the reset source read from the watchdog registers, interpret the SRSR value corresponding to watchdog reset as "lookup details in the watchdog registers".

2018-06-26	edb4379 Browse files » watchdog: rave-sp-wdt: Explicitly access EEPROM for bootsource ... RAVE SP firmware versions found on RDU2 provide decicated bootsource manipulation commands, which, under the hood, are just thin wrappers around write/read to a particular location in EEPROM. Unfortunately, RAVE SP firmware found on RDU1, does not provide any dedicated bootsource commands and its users are expected to access EEPROM directly. In order to avoid having separate code paths for handling those two cases, convert the code to access EEPROM directly via NVMEM API.

This has been fixed in the Linux driver which honours a fsl,ext-reset-output device tree property to select between both ways. Do the same in the barebox driver.
