2020-07-09include/cpu/amd/msr: move SMM_LOCK bit right after HWCR_MSR definitionFelix Held
The SMM_LOCK bit isn't in SMM_MASK_MSR, but in HWCR_MSR, so move it there. The soc/amd/* code itself uses the bit definition when accessing HWCR_MSR, so SMM_LOCK was just below the wrong MSR definition. Also remove SMM_LOCK from comment about masking bits in SMM_MASK_MSR, since that bit isn't in that MSR. TEST=Checked the code and the corresponding BKDG/PPR.

According to the comments of https://review.coreboot.org/c/coreboot/+/41719 , which is about Microcode patch for amd/picasso. Change the code with the same way. The changes include: 1. combine the microcode_xxx.c and update_microcode.c into one source. 2. Redefine the microcode updating function to eliminate the parameter. Get the revision ID in the black box. Reduce the depth of function calls. 3. Get the revision ID by bitwise calculation instead of lookup table. 4. Reduce the confusing type casts. 5. Squash some lines. We do not change the way it used to be. The code assume only one microcode is integrated in CBFS. If needed in future, 41719 is the example of integrating multiple binaries. And, 41719 depends on the definition in this patch.

2020-03-17src (minus soc and mainboard): Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2020-03-15treewide: Replace uses of "Nehalem"Angel Pons
The code in coreboot is actually for the Arrandale processors, which are a MCM (Multi-Chip Module) with two different dies: - Hillel: 32nm Westmere dual-core CPU - Ironlake: 45nm northbridge with integrated graphics This has nothing to do with the older, single-die Nehalem processors. Therefore, replace the references to Nehalem with the correct names.

2020-03-07cpu/x86/smm: Add smm_size to relocatable smmstubArthur Heymans
To mitigate against sinkhole in software which is required on pre-sandybridge hardware, the smm entry point needs to check if the LAPIC base is between smbase and smbase + smmsize. The size needs to be available early so add them to the relocatable module parameters. When the smmstub is used to relocate SMM the default SMM size 0x10000 is provided. On the permanent handler the size provided by get_smm_info() is used.

2020-02-21security/intel/stm: Check for processor STM supportEugene Myers
Check to ensure that dual monitor mode is supported on the current processor. Dual monitor mode is normally supported on any Intel x86 processor that has VTx support. The STM is a hypervisor that executes in SMM dual monitor mode. This check should fail only in the rare case were dual monitor mode is disabled. If the check fails, then the STM will not be initialized by coreboot. Signed-off-by: Eugene D.

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.
