  10           If you have a TPM security chip in your system, which
  11           implements the Trusted Computing Group's specification,
  12           say Yes and it will be accessible from within Linux.  For
  13           more information see <http://www.trustedcomputinggroup.org>.
  14           An implementation of the Trusted Software Stack (TSS), the
  15           userspace enablement piece of the specification, can be
  16           obtained at: <http://sourceforge.net/projects/trousers>.  To
  17           compile this driver as a module, choose M here; the module
  18           will be called tpm. If unsure, say N.
  19           Notes:
  20           1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI
  21           and CONFIG_PNPACPI.
  22           2) Without ACPI enabled, the BIOS event log won't be accessible,
  23           which is required to validate the PCR 0-7 values.
