9	select SECURITYFS
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.

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

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.

51	depends on PNP
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.
