Description

> Surprisingly, on Librem 14 (and others IIRC), the clock resets to 2070, not 1970. Maybe if I enable the RTC century bit in CMOS it'll reset to 1970 instead.

Research direction

Start by reviewing how coreboot configures the CMOS RTC century bit for the Librem 14, then compare that behavior across the supported boards. Verify whether the bit is set consistently and confirm whether the clock initializes to the expected century; record any boards that differ.
