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"
