From dce9be4dda079d420e811533487bf19c97da1216 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 26 Mar 2025 15:29:07 -0600 Subject: [PATCH] tpm: Export the function to set up the TPM log In some cases, we may wish to set up the TPM log under full control of a driver in U-Boot. Export the required function to make this possible. This avoids calling the weak function tcg2_platform_get_log() when the caller already knows where the log is.
