7config TCG_TPM
8	tristate "TPM Hardware Support"
9	depends on EXPERIMENTAL
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	  Note: For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI
21	  and CONFIG_PNPACPI.

23config TCG_TIS
24	tristate "TPM Interface Specification 1.2 Interface"
25	depends on TCG_TPM && PNPACPI
26	---help---
27	  If you have a TPM security chip that is compliant with the
28	  TCG TIS 1.2 TPM specification say Yes and it will be accessible
29	  from within Linux.  To compile this driver as a module, choose
30	  M here; the module will be called tpm_tis.

32config TCG_NSC
33	tristate "National Semiconductor TPM Interface"
34	depends on TCG_TPM && PNPACPI
35	---help---
36	  If you have a TPM security chip from National Semicondutor
37	  say Yes and it will be accessible from within Linux.  To
38	  compile this driver as a module, choose M here; the module
39	  will be called tpm_nsc.

41config TCG_ATMEL
42	tristate "Atmel TPM Interface"
43	depends on TCG_TPM
44	---help---
45	  If you have a TPM security chip from Atmel say Yes and it
46	  will be accessible from within Linux.  To compile this driver
47	  as a module, choose M here; the module will be called tpm_atmel.
48
49config TCG_INFINEON
50	tristate "Infineon Technologies TPM Interface"
51	depends on TCG_TPM && PNPACPI
52	---help---
53	  If you have a TPM security chip from Infineon Technologies
54	  (either SLD 9630 TT 1.1 or SLB 9635 TT 1.2) say Yes and it
55	  will be accessible from within Linux.
56	  To compile this driver as a module, choose M here; the module
57	  will be called tpm_infineon.
58	  Further information on this driver and the supported hardware
59	  can be found at http://www.prosec.rub.de/tpm
