      x86, intel_txt: Intel TXT boot support · 31625340
      Joseph Cihula authored
      This patch adds kernel configuration and boot support for Intel Trusted
      Execution Technology (Intel TXT).
      
      Intel's technology for safer computing, Intel Trusted Execution
      Technology (Intel TXT), defines platform-level enhancements that
      provide the building blocks for creating trusted platforms.
      
      Intel TXT was formerly known by the code name LaGrande Technology (LT).
      
      Intel TXT in Brief:
      o  Provides dynamic root of trust for measurement (DRTM)
      o  Data protection in case of improper shutdown
      o  Measurement and verification of launched environment
      
      Intel TXT is part of the vPro(TM) brand and is also available some
      non-vPro systems.  It is currently available on desktop systems based on
      the Q35, X38, Q45, and Q43 Express chipsets (e.g. Dell Optiplex 755, HP
      dc7800, etc.) and mobile systems based on the GM45, PM45, and GS45
      Express chipsets.
      
      For more information, see http://www.intel.com/technology/security/
      
      .
      This site also has a link to the Intel TXT MLE Developers Manual, which
      has been updated for the new released platforms.
      
      A much more complete description of how these patches support TXT, how to
      configure a system for it, etc. is in the Documentation/intel_txt.txt file
      in this patch.
      
      This patch provides the TXT support routines for complete functionality,
      documentation for TXT support and for the changes to the boot_params structure,
      and boot detection of a TXT launch.  Attempts to shutdown (reboot, Sx) the system
      will result in platform resets; subsequent patches will support these shutdown modes
      properly.
