6	tristate "TPM Hardware Support"
7	depends on HAS_IOMEM
8	depends on EXPERIMENTAL
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	  Note: For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI
20	  and CONFIG_PNPACPI.

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

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

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.

49config TCG_INFINEON
50	tristate "Infineon Technologies TPM Interface"
51	depends on 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
