From a quick look at the code, you need to enable CONFIG_WDT_AT91 and the watchdog won't be disabled anymore by the SPL.

See: https://elixir.bootlin.com/u-boot/latest/source/arch/arm/mach-at91/spl_atmel... and https://elixir.bootlin.com/u-boot/latest/source/arch/arm/mach-at91/spl.c#L16

Good catch, thanks! Indeed setting CONFIG_WDT_AT91=y did the trick.

I didn't consider enabling the watchdog driver to avoid disabling the watchdog timer! Thanks again, Michael.
