menuconfig TCG_TPM
	tristate "TPM Hardware Support"
	depends on HAS_IOMEM
	depends on EXPERIMENTAL
	select SECURITYFS
	---help---
	  If you have a TPM security chip in your system, which
	  implements the Trusted Computing Group's specification,
	  say Yes and it will be accessible from within Linux.  For
	  more information see <http://www.trustedcomputinggroup.org>. 
	  An implementation of the Trusted Software Stack (TSS), the 
	  userspace enablement piece of the specification, can be 
	  obtained at: <http://sourceforge.net/projects/trousers>.  To 
	  compile this driver as a module, choose M here; the module 
	  will be called tpm. If unsure, say N.
	  Note: For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI
	  and CONFIG_PNPACPI.

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

config TCG_NSC
	tristate "National Semiconductor TPM Interface"
	---help---
	  If you have a TPM security chip from National Semiconductor 
	  say Yes and it will be accessible from within Linux.  To 
	  compile this driver as a module, choose M here; the module 
	  will be called tpm_nsc.

config TCG_ATMEL
	tristate "Atmel TPM Interface"
	---help---
	  If you have a TPM security chip from Atmel say Yes and it 
	  will be accessible from within Linux.  To compile this driver 
	  as a module, choose M here; the module will be called tpm_atmel.

config TCG_INFINEON
	tristate "Infineon Technologies TPM Interface"
	depends on PNP
	---help---
	  If you have a TPM security chip from Infineon Technologies
	  (either SLD 9630 TT 1.1 or SLB 9635 TT 1.2) say Yes and it
	  will be accessible from within Linux.
	  To compile this driver as a module, choose M here; the module
	  will be called tpm_infineon.
	  Further information on this driver and the supported hardware
	  can be found at http://www.prosec.rub.de/tpm
