watchdog: mpc8xx_wdt: Allow selection of watchdog mode through environment

2020-04-24T14:09:59Z

The mpc8xx watchdog can work either in 'reset mode' or 'NMI mode'. The selection can be done at startup only. It is desirable to select the mode without rebuilding U-boot. It is also desirable to disable the watchdog without rebuilding. At watchdog startup, check environment variable 'watchdog_mode'. If it is 'off', the watchdog is not started. If it is 'nmi', the watchdog is started in NMI mode. Otherwise, it is started in reset mode which is the default mode. Signed-off-by: Charles Frey Signed-off-by: Christophe Leroy

watchdog: honour hw_margin_ms DT property

2020-04-15T06:54:00Z

Some watchdog devices, e.g. external gpio-triggered ones, must be reset more often than once per second, which means that the current rate-limiting logic in watchdog_reset() fails to keep the board alive. gpio-wdt.txt in the linux source tree defines a "hw_margin_ms" property used to specifiy the maximum time allowed between resetting the device. Allow any watchdog device to specify such a property, and then use a reset period of one quarter of that. We keep the current default of resetting once every 1000ms.

watchdog: move initr_watchdog() to wdt-uclass.c

2020-04-15T06:53:55Z

This function is a bit large for an inline function, and for U-Boot proper, it is called via a function pointer anyway (in board_r.c), so cannot be inlined. It will shortly set a global variable to be used by the watchdog_reset() function in wdt-uclass.c, so this also allows making that variable local to wdt-uclass.c. The WATCHDOG_TIMEOUT_SECS define is not used elsewhere. Signed-off-by: Rasmus Villemoes Reviewed-by: Stefan Roese
