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

31	  If you have a TPM security chip that is compliant with the
32	  TCG TIS 1.2 TPM specification say Yes and it will be accessible
33	  from within Linux.  To compile this driver as a module, choose
34	  M here; the module will be called tpm_tis.

39	  If you have a TPM security chip from National Semiconductor
40	  say Yes and it will be accessible from within Linux.  To
41	  compile this driver as a module, choose M here; the module
42	  will be called tpm_nsc.

47	  If you have a TPM security chip from Atmel say Yes and it
48	  will be accessible from within Linux.  To compile this driver
49	  as a module, choose M here; the module will be called tpm_atmel.

54	---help---
55	  If you have a TPM security chip from Infineon Technologies
56	  (either SLD 9630 TT 1.1 or SLB 9635 TT 1.2) say Yes and it
57	  will be accessible from within Linux.
58	  To compile this driver as a module, choose M here; the module
59	  will be called tpm_infineon.
