[PATCH v4 0/3] tpm: Fix default choices for CRB and SPAPR dev models
From: Stefan Berger <stefanb@linux.ibm.com> This series of patches adds an additional check for the SPAPR device model that prevents the choice of a TPM 1.2 backend and chooses a TPM 2 as default. Also CRB now chooses a TPM 2 as default since TPM 1.2 wouldn't work with it, either.

From: Stefan Berger <stefanb@linux.ibm.com> The firmware (SLOF) on QEMU for ppc64 does not support TPM 1.2, so prevent the choice of TPM 1.2 when the SPAPR device model is chosen and use a default of '2.0' (TPM 2) for the backend.
