2023-09-12arch/x86: Reduce max phys address size for Intel TME capable SoCsJeremy Compostella
On Intel SoCs, if TME is supported, TME key ID bits are reserved and should be subtracted from the maximum physical addresses available. BUG=288978352 TEST=Verified that DMAR ACPI table `Host Address Width` field on rex went from 45 to 41.

2021-06-22soc/intel/car: Add support for bootguard CARArthur Heymans
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. TESTED on prodrive/hermes with bootguard enabled.

2021-06-21soc/intel/common: Add InSMM.STS supportAngel Pons
Tested on HP 280 G2, SMMSTORE v1 and v2 still work. Other tests: - If one does not set BIOS_CONTROL bit WPD, SMMSTORE breaks. - If one does not write the magic MSR `or 1`, SMMSTORE breaks.

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.

2021-05-28cpu/x86/entry16.S: Make Intel CBnT TOCTOU safeArthur Heymans
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.

2020-10-31cpu/intel/common: correct MSR for the Nominal Performance in CPPCMichael Niewöhner
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.

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.
