PS1, Line 10: MSR_VR_MISC_CONFIG2
> Yeah I see it defined in the EDS, but FSP does not program it, and neither does coreboot.

Yes, for that, the commit msg need to be updated to reflect the same "The `MSR_VR_MISC_CONFIG2` was copy-pasted from Haswell/Broadwell code, but newer processors never used MSR 0x636, hence dropping with this code change".

"newer processors don't have this MSR." => I read this as EDS doesn't have this MSR defined.
