+	tristate "TPM Hardware Support"
+	depends on HAS_IOMEM
+	select SECURITYFS
+	select CRYPTO
+	select CRYPTO_HASH_INFO
+	---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.
+	  Notes:
+	  1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI
+	  and CONFIG_PNPACPI.
+	  2) Without ACPI enabled, the BIOS event log won't be accessible,
+	  which is required to validate the PCR 0-7 values.

+config HW_RANDOM_TPM
+	bool "TPM HW Random Number Generator support"
+	depends on TCG_TPM && HW_RANDOM && !(TCG_TPM=y && HW_RANDOM=m)
+	default y
+	---help---
+	  This setting exposes the TPM's Random Number Generator as a hwrng
+	  device. This allows the kernel to collect randomness from the TPM at
+	  boot, and provides the TPM randomines in /dev/hwrng.
+
+	  If unsure, say Y.
+
+config TCG_TIS_CORE
+	tristate
+	---help---
+	TCG TIS TPM core driver. It implements the TPM TCG TIS logic and hooks
+	into the TPM kernel APIs. Physical layers will register against it.

+	  TCG TIS 1.2 TPM specification (TPM1.2) or the TCG PTP FIFO
+	  specification (TPM2.0) 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.

+	---help---
+	  If you have a TPM security chip which is connected to a regular,
+	  non-tcg SPI master (i.e. most embedded platforms) that is compliant with the
+	  TCG TIS 1.3 TPM specification (TPM1.2) or the TCG PTP FIFO
+	  specification (TPM2.0) 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_spi.
+
+config TCG_TIS_I2C_ATMEL
+	tristate "TPM Interface Specification 1.2 Interface (I2C - Atmel)"
+	depends on I2C
+	---help---
+	  If you have an Atmel I2C TPM security chip 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_i2c_atmel.
+
+config TCG_TIS_I2C_INFINEON
+	tristate "TPM Interface Specification 1.2 Interface (I2C - Infineon)"
+	depends on I2C
+	---help---
+	  If you have a TPM security chip that is compliant with the
+	  TCG TIS 1.2 TPM specification and Infineon's I2C Protocol Stack
+	  Specification 0.20 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_i2c_infineon.
+
+config TCG_TIS_I2C_NUVOTON
+	tristate "TPM Interface Specification 1.2 Interface (I2C - Nuvoton)"
+	depends on I2C
+	---help---
+	  If you have a TPM security chip with an I2C interface from
+	  Nuvoton Technology Corp. 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_i2c_nuvoton.
+
+config TCG_NSC
+	tristate "National Semiconductor TPM Interface"
+	depends on X86
+	---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.
+

+	  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.trust.rub.de/projects/linux-device-driver-infineon-tpm/
