From 79274e01a3722a559f46c3ae284e7057b54cbecb Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Mon, 19 Jun 2023 11:32:19 +0000 Subject: driver/intel/fsp2_0: Add support to store MRC cache using MRC version MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch uses the "generic" variable name as "version" while storing the MRC cache data instead referring to the FSP-M version or MRC version. Hence, updated all the instances of `fsp_version/fspm_version` with `version`. Also introduces the new option to the MRC cache version that allows SoC users to store the MRC cache version based on the supported EDK2 version. Intel FSP built with EDK2 version 202302 onwards has support to retrieve the MRC version by directly parsing the binary. Additionally, added the helper function `fsp_mrc_version()` and corresponding header file to read the MRC version from the FSP binary. BUG=b:261689642 TEST=Able to build and boot google/rex and google/omnigul.
