[coreboot] Re: Does Coreboot support the following options to enable/disable?

[Lance Zhao]

That's Denverton? If the selection is not part of fspupd file
https://github.com/IntelFsp/FSP/tree/master/DenvertonNSFspBinPkg/Include,
then probably they only have default setting. We can't enable/disable those
option through FSP didn't mean those feature is not available.
