2021-10-21acpigen,soc/amd,cpu/intel: rework static DWORD for CPPC tableMichael Niewöhner
Some elements in the ACPI CPPC table allow static DWORDs. Instead of using a fake register resource, use a tagged union with the two types "register" and "DWORD" and respective macros for CPPC table entries. Test: dumped SSDT before and after do not differ.

Rework the code moved to common code in CB:46274. This involves simplification by using appropriate helpers for MSR and CPUID, using macros instead of plain values for MSRs and cpu features and adding documentation to the header.

2018-12-20cpu/intel/common: decouple IA32_FEATURE_CONTROL lock from set_vmx()Matt DeVillier
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 indicate 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 Change-Id: Iee772fe87306b4729ca012cef8640d3858e2cb06 Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-on: https://review.coreboot.org/c/30229 Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: David Guckian Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
