2021-01-11cpu/intel/haswell: Add delay for TPM before Flex Ratio rebootAngel Pons
Commit 542307b815 (broadwell: Add small delay before Flex Ratio reboot) introduced a workaround for Broadwell. Implement it on Haswell as well. Since this is only necessary when a TPM is present on a system, only do the delay (which is not that small, to be honest) on TPM-enabled builds.

2020-12-02cbfs: Simplify load/map API names, remove type argumentsJulius Werner
This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file() to cbfs_map() and cbfs_load() respectively. This is supposed to be the start of a new, better organized CBFS API where the most common operations have the most simple and straight-forward names. Less commonly used variants of these operations (e.g. cbfs_ro_load() or cbfs_region_load()) can be introduced later. It seems unnecessary to keep carrying around "boot" in the names of most CBFS APIs if the vast majority of accesses go to the boot CBFS (instead, more unusual operations should have longer names that describe how they diverge from the common ones). cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly reap mappings when desired. A few new cbfs_unmap() calls are added to generic code where it makes sense, but it seems unnecessary to introduce this everywhere in platform or architecture specific code where the boot medium is known to be memory-mapped anyway. In fact, even for non-memory-mapped platforms, sometimes leaking a mapping to the CBFS cache is a much cleaner solution than jumping through hoops to provide some other storage for some long-lived file object, and it shouldn't be outright forbidden when it makes sense. Additionally, remove the type arguments from these function signatures. The goal is to eventually remove type arguments for lookup from the whole CBFS API. Filenames already uniquely identify CBFS files. The type field is just informational, and there should be APIs to allow callers to check it when desired, but it's not clear what we gain from forcing this as a parameter into every single CBFS access when the vast majority of the time it provides no additional value and is just clutter.

2020-11-09cpu/x86/smm: Add a common save state handlingArthur Heymans
Currently coreboot has limited use for the SMM save state. Typically the only thing needed is to get or set a few registers and to know which CPU triggered the SMI (typically via an IO write). Abstracting away different SMM save states would allow to put some SMM functionality like the SMMSTORE entry in common places. To save place platforms can select different SMM save sate ops that should be implemented. For instance AMD platforms don't need Intel SMM save state handling. Some platforms can encounter CPUs with different save states, which the code then handles at runtime by comparing the SMM save state revision which is located at the same offset for all SMM save state types.

2020-10-20cpu/x86/mtrr: add support for address space higher than 16TiBJonathan Zhang
On DeltaLake server, there are following entry in MTRR address space: 0x0000201000000000 - 0x0000201000400000 size 0x00400000 type 0 In this case, the base address (with 4k granularity) cannot be held in uint32_t. This results incorrect MTRR register setup. As the consequence UEFI forum FWTS reports following critical error: Memory range 0x100000000 to 0x183fffffff (System RAM) has incorrect attribute Uncached. Change appropriate variables' data type from uint32_t to uint64_t. Add fls64() to find least significant bit set in a 64-bit word. Add fms64() to find most significant bit set in a 64-bit word.

2020-10-16include/cpu/x86: introduce new helper for (un)setting MSRsMichael Niewöhner
msr_set_bit can only set single bits in MSRs and causes mixing of bit positions and bitmasks in the MSR header files. Thus, replace the helper by versions which can unset and set whole MSR bitmasks, just like the "and-or"-helper, but in the way commit 64a6b6c was done (inversion done in the helper). This helps keeping the MSR macros unified in bitmask style. In sum, the three helpers msr_set, msr_unset and msr_unset_and_set get added. The few uses of msr_set_bit have been replaced by the new version, while the used macros have been converted accordingly.

This wasn't noticed with QEMU as the DRAM is up and address 32 is valid. On real hardware when CAR is running this instruction causes a crash.

2020-09-12cpu/intel/model_1067x: enable PECIMichael Büchler
This is required for Super I/Os to be able to read the CPU temperature through PECI. On 45nm Core 2 CPUs (Wolfdale, Yorkfield) it is not enabled by default. This is probably related to erratum AW67 "Enabling PECI via the PECI_CTL MSR incorrectly writes CPUID_FEATURE_MASK1 MSR". The suggested workaround is "Do not initialize PECI before processor update is loaded". Since coreboot performs microcode updates before running this code it should not cause any trouble. It was tested on a Core 2 Duo E8400, stepping E0. PECI is already enabled by default on older (65nm) CPUs. Tested: Pentium Dual-Core E2160.
