From f61427709909bb9fa534f985eb451b3b905f7a31 Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Wed, 27 Sep 2017 18:33:33 +0200 Subject: soc/intel/common: Allow overriding CBFS filename of VBT When reusing the same image across multiple devices, they sometimes need different VBTs, so provide a hook for mainboard code to specify which file is required.
