From: Stefan Berger <stefanb(a)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.

New subject: [PATCH v4 2/3] qemu: Set SPAPR TPM default to 2.0 and prevent 1.2 choice
From: Stefan Berger <stefanb(a)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.
