From 0f7d2148201932c6a02b310543b1e50503a0ab2d Mon Sep 17 00:00:00 2001 From: Philippe Mathieu-Daudé Date: Fri, 12 Jun 2020 10:54:43 +0200 Subject: hw/tpm: Make 'tpm_util.h' publicly accessible as "sysemu/tpm_util.h" We are going to split the TPM backends from the TPM emulated hardware in the next commit. Make the TPM util helpers accessible by moving local "tpm_util.h" to global "sysemu/tpm_util.h".
