to look at the new patch set (#2).

mainboard/lenovo/x60: Add TPM 1.2 mainboard support

This was adapted from the following commit:
  3d02b9c mainboard/lenovo/{t430s,t420s,t520,t530,x220}: Add TPM 1.2 mainboard support

Without that patch, coreboot doesn't touch the TPM, and,
in GNU/Linux, the TPM is not detected automatically.
It could still be used by running:
  modprobe tpm_tis itpm=1 force=1
which initializes it. From dmesg:
  tpm_tis tpm_tis: 1.2 TPM (device-id 0x3202, rev-id 5)
  tpm tpm0: A TPM error (38) occurred attempting to determine the timeouts
  tpm tpm0: Issuing TPM_STARTUP
  tpm tpm0: [Hardware Error]: Adjusting reported timeouts: A 10000->10000us B 10000->10000us C 0->750000us D 0->750000us

With this patch, the TPM is found detected automatically,
and we have the folliwing in dmesg:
  tpm_tis 00:07: 1.2 TPM (device-id 0x3202, rev-id 5)
  tpm tpm0: A TPM error (38) occurred attempting to determine the timeouts
  tpm tpm0: Issuing TPM_STARTUP
  tpm tpm0: [Hardware Error]: Adjusting reported timeouts: A 10000->10000us B 10000->10000us C 0->750000us D 0->750000us
