From 10ea93c3341dcae75b29e7dd049a948260d0f190 Mon Sep 17 00:00:00 2001 From: Lijian Zhao Date: Thu, 11 Apr 2019 00:45:10 -0700 Subject: [PATCH] smbios: Add type 17 device/bank locator override Current SMBIOS type 17 device and bank locator string is like "Channel-x-Dimm-x" and "Bank-x", x is deciminal number. Give silicon or mainboard vendor a chance to replace with something matches with silkscreen.
