TPM 2.0 potentially supported
==============================
The onboard TPM is an SLB 9660, which supports TPM 1.2 but it is known to be
compatible with TPM 2.0 via firmware upgrade. Although not yet tested, we have
some notes about that here:
[../../tasks/#hp-820-g2-tpm](../../tasks/#hp-820-g2-tpm)
Not yet used meaningfully by Libreboot itself, but the TPM can be used to
implement things like measured boot.
