Removing all of them also removes CONFIG_HPET_EMULATE_RTC which makes me
a bit nervous. The reason is:
config HPET_EMULATE_RTC
	def_bool y
	depends on HPET_TIMER && (RTC=y || RTC=m || RTC_DRV_CMOS=m || RTC_DRV_CMOS=y)
so I have to have RTC and RTC_DRV_CMOS turned on.

Is turning of CONFIG_HPET_EMULATE_RTC a good idea? Then I will not have
a rtc at all, right?

Best wishes

Norbert
