+	select CRYPTO_HASH_INFO
+	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.
