From 540af0960217a1d25600d6ef5f0048f4a9b391fd Mon Sep 17 00:00:00 2001 From: Marco Chen Date: Thu, 26 Mar 2020 22:23:17 +0800 Subject: soc/intel/tigerlake: Allow mainboard to override DRAM part number In order to support mainboards that do not store DRAM part number in the traditional way i.e. within the CBFS SPD for soldered memory, this change provides a runtime callback to allow mainboards to provide DRAM part number from a custom location e.g. external EEPROM on volteer / dedede. For other boards it should be a NOP since the weak implementation of mainboard_get_dram_part_num does nothing.
