2021-01-08cpu/intel/model_206ax: Always return a package from _CSTAngel Pons
The _CST method is supposed to return a package. If a mainboard used zero for all ACPI C-states, the generated _CST would return nothing, which is invalid. Instead, return a package with no C-state entries. This change is a no-op, since all mainboards have at least one valid ACPI C-state. This is what `acpigen_write_CST_package()` does, too.

2021-01-07arch/x86: Move prologue to .init sectionKyösti Mälkki
For arch/x86 the realmode part has to be located within the same 64 KiB as the reset vector. Some older intel platforms also require 4 KiB alignment for _start16bit. To enforce the above, and to separate required parts of .text without matching *(.text.*) rules in linker scripts, tag the pre-C environment assembly code with section .init directive. Description of .init section for ELF: This section holds executable instructions that contribute to the process initialization code. When a program starts to run, the system arranges to execute the code in this section before calling the main program entry point (called main for C programs).

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.

2020-10-17cpu/intel,soc/intel: drop Kconfig for hyperthreadingMichael Niewöhner
Drop the Kconfig for hyperthreading to be always able to check at runtime if hyperthreading is supported. Having a Kconfig for this doesn't have any benefit.

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.

2020-10-02drivers/spi: Add BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES configShelley Chen
Added new config BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES to accomodate older x86 platforms that don't allow writing to SPI flash when early stages are running XIP from flash. If BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES is not selected, BOOT_DEVICE_SPI_FLASH_RW_NOMMAP_EARLY will get auto-selected if BOOT_DEVICE_SPI_FLASH_RW_NOMMAP=y. This allows for current platforms that write to flash in the earlier stages, assuming that they have that capability. BUG=b:150502246 BRANCH=None TEST=diff the coreboot.rom files resulting from running ./util/abuild/abuild -p none -t GOOGLE_NAMI -x -a --timeless with and without this change to make sure that there was no difference. Also did this for GOOGLE_CANDY board, which is baytrail based (and has BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES enabled).

2020-09-28cpu/intel/206ax/acpi.c: Fix get_cores_per_packageEvgeny Zinoviev
Current implementation uses CPUID 0Bh function that returns the number of logical cores of requested level. The problem with this approach is that this value doesn't change when HyperThreading is disabled (it's in the Intel docs), so it breaks generate_cpu_entries(). - Use MSR 0x35 instead, which returns the correct number of logical processors with and without HT. - Rename the function to get_logical_cores_per_package, which is more accurate. Tested on ThinkPad X220 with and without HT. Related to CB:29669.

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. See commit edac28ce65e48d6b2a0a2421d046a4fe4b2bf589 for the same change on cpu/intel/model_6fx.
