2020-02-05security/intel/stm: Add STM supportEugene Myers
This update is a combination of all four of the patches so that the commit can be done without breaking parts of coreboot. This possible breakage is because of the cross-dependencies between the original separate patches would cause failure because of data structure changes. security/intel/stm This directory contains the functions that check and move the STM to the MSEG, create its page tables, and create the BIOS resource list. The STM page tables is a six page region located in the MSEG and are pointed to by the CR3 Offset field in the MSEG header. The initial page tables will identity map all memory between 0-4G. The STM starts in IA32e mode, which requires page tables to exist at startup. The BIOS resource list defines the resources that the SMI Handler is allowed to access. This includes the SMM memory area where the SMI handler resides and other resources such as I/O devices. The STM uses the BIOS resource list to restrict the SMI handler's accesses. The BIOS resource list is currently located in the same area as the SMI handler. This location is shown in the comment section before smm_load_module in smm_module_loader.c Note: The files within security/intel/stm come directly from their Tianocore counterparts. Unnecessary code has been removed and the remaining code has been converted to meet coreboot coding requirements.

2020-02-04cpu/x86: Make MP init timeout configurableJonathan Zhang
The current MP init timeout is hardcoded as 1s. To support platform with many cpus, the timeout needs to be adjusted. The number of cpus is calculated as: number of sockets * number of cores per socket * number of threads per core How long the timeout should be set to, is heuristic. It needs to be set long enough to ensure reboot stability, but not unreasonable so that real failures can be detected soon enough, especially for smaller systems. This patch sets timeout to be minimum as 1 second, while each cpu adds 0.1 second.

2019-11-26soc/intel/{apl,cnl,dnv,skl}: Skip ucode loading by FSP-TSubrata Banik
It is a requirement for Firmware to have Firmware Interface Table (FIT), which contains pointers to each microcode update. The microcode update is loaded for all logical processors before reset vector. FSPT_UPD.MicrocodeRegionBase and FSPT_UPD.MicrocodeRegionLength are input parameters to TempRamInit API. If these values are 0, FSP will not attempt to update microcode. Since Gen-4 all IA-SoC has FIT loading ucode even before cpu reset in place hence skipping FSP-T loading ucode after CPU reset options.

2019-11-03arch/arm: Pass cbmem_top to ramstage via calling argumentArthur Heymans
This solution is very generic and can in principle be implemented on all arch/soc. Instead trying to figure out which files can be removed from stages and which cbmem_top implementations need with preprocessor, rename all cbmem_top implementation to cbmem_top_romstage. Mechanisms set in place to pass on information from rom- to ram-stage will be placed in a followup commit.

2019-11-03cpu/x86/tsc: Flip and rename TSC_CONSTANT_RATE to UNKNOWN_TSC_RATEKyösti Mälkki
The x86 timers are a bit of a mess. Cases where different stages use different counters and timestamps use different counters from udelays. The original intention was to only flip TSC_CONSTANT_RATE Kconfig to NOT_CONSTANT_TSC_RATE. The name would be incorrect though, those counters do run with a constant rate but we just lack tsc_freq_mhz() implementation for three platforms. Note that for boards with UNKNOWN_TSC_RATE=y, each stage will have a slow run of calibrate_tsc_with_pit(). This is easy enough to fix with followup implementation of tsc_freq_mhz() for the platforms. Implementations with LAPIC_MONOTONIC_TIMER typically will not have tsc_freq_mhz() implemented and default to UNKNOWN_TSC_RATE. However, as they don't use TSC for udelay() the slow calibrate_tsc_with_pit() is avoided. Because x86/tsc_delay.tsc was using two different guards and nb/via/vx900 claimed UDELAY_TSC, but pulled UDELAY_IO implementation, we also switch that romstage to use UDELAY_TSC.

2019-11-02cpu/x86: Add a prog_run hook to set up caching of XIP stagesArthur Heymans
Some platforms lack a non-eviction mode and therefore caching the whole ROM to speed up XIP stages can be dangerous as it could result in eviction if too much of the ROM is being accessed. The solution is to only cache a region, about the size of the stage that the bootblock is about to load: verstage and/or romstage. TODO: now a limit of 256KiB is set for the total amount of cache that can be used. This should fit most use cases for the time being.

2019-10-28nb/intel/gm45: Add C_ENVIRONMENT_BOOTBLOCK supportArthur Heymans
The i82801ix_early_init is now called both in the bootblock and romstage. The rationale behind setting this up twice is to ensure bootblock-romstage compatibility in the future if for instance VBOOT is used. This moves the console init to the bootblock. The romstage now runs uncached. Adding a prog_run hooks to set up an MTRR to cache the romstage will be done in a followup patch. The default size of 64KiB is not modified for the bootblock as trying to fit both EHCI and SPI flash debugging needs a more space and 64KiB is the next power of 2 size that fits it.
