NAME

     tpm -- Trusted Platform Module

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device tpm

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   tpm_load="YES"

     In /boot/device.hints:
     hint.tpm.0.at="isa"
     hint.tpm.0.maddr="0xfed40000"
     hint.tpm.0.msize="0x5000"
     hint.tpm.1.at="isa"
     hint.tpm.1.maddr="0xfed40000"
     hint.tpm.1.msize="0x1000"

DESCRIPTION

     The tpm driver provides support for various trusted platform modules (TPM) that can store cryptographic keys.

     Supported modules:

	   o   Atmel 97SC3203
	   o   Broadcom BCM0102
	   o   Infineon IFX SLD 9630 TT 1.1 and IFX SLB 9635 TT 1.2
	   o   Intel INTC0102
	   o   Sinosun SNS SSX35
	   o   STM ST19WP18
	   o   Winbond WEC WPCT200

     The driver can be configured to use an IRQ by providing a free ISA interrupt vector in /boot/device.hints.
