cpu/intel/msr.h: Add license header This is most likely an oversight. Given that the coreboot project as a whole is licensed as GPLv2, add a GPL-2.0-only SPDX license identifier.

soc/intel/skl,cpu/intel: copy AES-NI locking to common cpu code Copy the AES-NI locking function to common cpu code to be able to reuse it. This change only copies the code and adds the MSR header file. Any further rework and later deduplication on the platforms code is done in the follow-up changes.

{cpu,soc}/intel: deduplicate cpu code Move a whole bunch of copy-pasta code from soc/intel/{bdw,skl,cnl,icl, tgl,ehl,jsl,adl} and cpu/intel/{hsw,model_*} to cpu/intel/common.

cpu/intel/common: rework code previously moved to common cpu code 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.

cpu/intel/common: correct MSR for the Nominal Performance in CPPC The "Nominal Performance" is not the same as the "Guaranteed Performance", but is defined as the performance a processor can deliver continously under ideal environmental conditions. According to edk2, this is the "Maximum Non-Turbo Ratio", which needs to be read from MSR_PLATFORM_INFO instead of IA32_HWP_CAPABILITIES. Correct the entry in the CPPC package.

soc/intel/car: Add support for bootguard CAR Bootguard sets up CAR/NEM on its own so the only thing needed is to find free MTRRs for our own CAR region and clear that area to fill in cache lines.

cpu/x86/entry16.S: Make Intel CBnT TOCTOU safe Intel CBnT (and Boot Guard) makes the chain of trust TOCTOU safe by setting up NEM (non eviction mode) in the ACM. The CBnT IBB (Initial BootBlock) therefore should not disable caching. Sidenote: the MSR macros are taken from the slimbootloader project. TESTED: ocp/Deltalake boot with and without CBnT and also a broken CBnT setup.
