9	---help---
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.

30	---help---
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.

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

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

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