This is not a fix so please drop that word from Subject.

I'd also expect you to mention that the RTC would be heavily crippled on
this machine as the efi variables cannot be updated.

Is there even a UEFI setup setting for this so that users that have
blown away Windows can ever set the time (which may become totally off
due to drift)?

I'm still not convinced that this is something we want, especially since
you could have a fully functional RTC by providing an SDAM offset
instead like we do on the sc8280xp CRD.
