[U-Boot] [BUG] bootloop with 2019-07 on Bananapi-r2

[Frank Wunderlich]

just FYI

problematic part of the Patch "watchdog: Implement generic watchdog_reset() version" seems to be this:

--- a/drivers/watchdog/Kconfig
+++ b/drivers/watchdog/Kconfig
@@ -51,6 +51,7 @@ config ULP_WATCHDOG

        help
          Enable driver model for watchdog timer. At the moment the API
          is very simple and only supports four operations:


which enables WATCHDOG if WDT is enabled (WATCHDOG was not enabled for my board with 2019-04).

I guess there is any mistake in the watchdog-driver (drivers/watchdog/mtk_wdt.c) which causes the board reset itself, but this was not happen before because CONFIG_WATCHDOG was disabled.
i removed this part in my repo (as temporary fix), compiles without errors and does not do a board reset :)
