      security/intel/txt: Add Intel TXT support · 5f9f7767
      Philipp Deppenwiese authored
      Add TXT ramstage driver:
       * Show startup errors
       * Check for TXT reset
       * Check for Secrets-in-memory
       * Add assembly for GETSEC instruction
       * Check platform state if GETSEC instruction is supported
       * Configure TXT memory regions
       * Lock TXT
       * Protect TSEG using DMA protected regions
       * Place SINIT ACM
       * Print information about ACMs
      Extend the `security_clear_dram_request()` function:
       * Clear all DRAM if secrets are in memory
      Add a config so that the code gets build-tested. Since BIOS and SINIT
      ACM binaries are not available, use the STM binary as a placeholder.
      Tested on OCP Wedge100s and Facebook Watson
       * Able to enter a Measured Launch Environment using SINIT ACM and TBOOT
       * Secrets in Memory bit is set on ungraceful shutdown
       * Memory is cleared after ungraceful shutdown

      mainboard/ocp: Add support for OCP platform TiogaPass · 75985f1d
      Jonathan Zhang authored
      OCP platform Tiogapass is a 2-socket server platform, which
      is based on a chipset including Intel Skylake-SP processors
      and a Lewisburg PCH. Skylake-SP is a processor in Intel Xeon
      Scalable Processor family.
      Following ACPI tables are added:
      This patchset is tested on a Tiogapass board. It booted with
      Linux kernel 4.16.0; lscpu command shows all 72 cpus (2 sockets,
      18 cores, 2 thread per core); ssh command shows
      networking is up from Mellanox ConnectX-4 PCIe NIC card.
      Towards successful gerrit buildbot build, note that:
      * microcode is in coreboot intel-microcode submodule repo.
      * IFD binary is included in this patch.
      * Dummy ME binary is used, as it may take long time for Intel
      ME binary to be available in public domain.
      * Fake FSP binary is used, as at this moment the SKX-SP
      FSP binary is not going to be available in public domain.
      Known issues (Not intend to address in this initial support for
      Xeon-SP processors):
      * c6 state is not supported.
      * dsdt table is not fully populated, such as processor/socket
      devices, some PCIe devices.
      * SMM handlers are not added.
      Following are some command execution with CentOS booted from
      local SATA disk:

      security/intel/stm: Add STM support · ae438be5
      Eugene Myers authored
      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.
      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.
      For more information see:
           SMI Transfer Monitor (STM) User Guide, Intel Corp.,
           August 2015, Rev 1.0, can be found at firmware.intel.com
      Addtions to include/cpu/x86 for STM support.
      STM Set up - The STM needs to be loaded into the MSEG during BIOS
      initialization and the SMM Monitor Control MSR be set to indicate
      that an STM is in the system.
      SMI module loader modifications needed to set up the
      SMM descriptors used by the STM during its initialization
