[coreboot-gerrit] Change in ...coreboot[master]: cpu/intel/common: decouple IA32_FEATURE_CONTROL lock from set_vmx()

[Matt DeVillier (Code Review)]

Hello Patrick Rudolph, build bot (Jenkins), Nico Huber, David Guckian,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).

cpu/intel/common: decouple IA32_FEATURE_CONTROL lock from set_vmx()

Newer CPUs/SoCs need to configure other features via the
IA32_FEATURE_CONTROL msr, such as SGX, which cannot be done if the
msr is already locked. Create separate functions for setting the
vmx flag and lock bit, and rename existing function to indiate that
the lock bit will be set in addition to vmx flag (per Kconfig).

This will allow Skylake/Kabylake (and others?) to use the common
VMX code without breaking SGX, while ensuring no change in functionality
to existing platforms which current set both together.

Test: build/boot each affected platform, ensure no change in functionality
