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:

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

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