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.
watchdog: Allow to use CONFIG_WDT without starting watchdog In some cases it is useful to compile support for U-Boot command 'wdt' without starting HW watchdog in early U-Boot phase. For example when the user want to start the watchdog only on demand by some boot script. This change adds a new compile option WATCHDOG_AUTOSTART to control whether U-Boot should automatically start the watchdog during init phase or not. This option is enabled by default as it was the default behavior prior introducing this new change. When compiling U-Boot users can decide to turn this option off.

watchdog: Implement generic watchdog_reset() version This patch tries to implement a generic watchdog_reset() function that can be used by all boards that want to service the watchdog device in U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG. Without this approach, new boards or platforms needed to implement a board specific version of this functionality, mostly copy'ing the same code over and over again into their board or platforms code base. With this new generic function, the scattered other functions are now removed to be replaced by the generic one. The new version also enables the configuration of the watchdog timeout via the DT "timeout-sec" property (if enabled via CONFIG_OF_CONTROL). This patch also adds a new flag to the GD flags, to flag that the watchdog is ready to use and adds the pointer to the watchdog device to the GD. This enables us to remove the global "watchdog_dev" variable, which was prone to cause problems because of its potentially very early use in watchdog_reset(), even before the BSS is cleared.

watchdog: add gpio watchdog driver A rather common kind of external watchdog circuit is one that is kept alive by toggling a gpio. Add a driver for handling such a watchdog. The corresponding linux driver apparently has support for some watchdog circuits which can be disabled by tri-stating the gpio, but I have never actually encountered such a chip in the wild; the whole point of adding an external watchdog is usually that it is not in any way under software control. For forward-compatibility, and to make DT describe the hardware, the current driver only supports devices that have the always-running property. I went a little back and forth on whether I should fail ->probe or only ->start, and ended up deciding ->start was the right place. The compatible string is probably a little odd as it has nothing to do with linux per se - however, I chose that to make .dts snippets reusable between device trees used with U-Boot and linux, and this is the (only) compatible string that linux' corresponding driver and DT binding accepts. I have asked whether one should/could add "wdt-gpio" to that binding, but the answer was no: https://lore.kernel.org/lkml/CAL_JsqKEGaFpiFV_oAtE+S_bnHkg4qry+bhx2EDs=NSbVf_giA@mail.gmail.com/ If someone feels strongly about this, I can certainly remove the "linux," part from the string - it probably wouldn't the only place where one can't reuse a DT snippet as-is between linux and U-Boot.

watchdog: mpc8xx: Revert the 8xx watchdog back to CONFIG_HW_WATCHDOG Commit f3729ba6e7b2 ("watchdog: mpc8xx_wdt: Watchdog driver and macros cleanup") switched the watchdog to CONFIG_WATCHDOG. But this is not compatible with the 8xx because it starts the watchdog HW timer at reset and must be serviced from the very beginning including while U-boot is executed in the firmware before relocation in RAM. Select CONFIG_HW_WATCHDOG and make hw_watchdog_reset() visible. Meanwhile, finalise the cleanup of arch/powerpc/cpu/mpc8xx/Kconfig by removing the lines put in comment in that commit, and also remove again the selection of CONFIG_MPC8xx_WATCHDOG which was removed by that commit and brought back by mistake by commit b3134ffbd944 ("watchdog: Kconfig: Sort entry alphabetically") Note that there was an 'imply WATCHDOG' in the original commit but it disappeared in the Kconfig alphabetical sorting, so no need to remove it here.
