  	---help---
  	  If you have a TPM security chip in your system, which
  	  implements the Trusted Computing Group's specification,
  	  say Yes and it will be accessible from within Linux.  For
  	  more information see <http://www.trustedcomputinggroup.org>. 
  	  An implementation of the Trusted Software Stack (TSS), the 
  	  userspace enablement piece of the specification, can be 
  	  obtained at: <http://sourceforge.net/projects/trousers>.  To 
  	  compile this driver as a module, choose M here; the module 
  	  will be called tpm. If unsure, say N.

  	  Notes:
  	  1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI

  	  and CONFIG_PNPACPI.

  	  2) Without ACPI enabled, the BIOS event log won't be accessible,
  	  which is required to validate the PCR 0-7 values.
