[Qemu-devel] [PULL v1 1/1] hw/tpm: Only build tpm_ppi.o if any of TPM_TI

From: Stefan Berger
Subject: [Qemu-devel] [PULL v1 1/1] hw/tpm: Only build tpm_ppi.o if any of TPM_TIS/TPM_CRB is built
Date: Mon, 8 Jul 2019 12:36:10 -0400

From: Philippe Mathieu-Daudé <address@hidden>

The TPM Physical Presence Interface routines are only used
by the CRB/TIS interfaces. Do not compile this file if any
of them is built.
