The imgpdc_wdt driver can be built on all architectures with CONFIG_COMPILE_TEST, but fails if no other watchdog driver is enabled:
drivers/watchdog/built-in.o: In function `pdc_wdt_remove': imgpdc_wdt.c:(.text+0x74): undefined reference to `watchdog_unregister_device' This adds the normal 'select WATCHDOG_CORE' that is needed to ensure the driver always builds cleanly.
