From 0f5b87cf95992ffddb9bc9bd08ee4d6af046bd92 Mon Sep 17 00:00:00 2001 From: David Milosevic Date: Thu, 20 Oct 2022 16:47:48 +0200 Subject: mb/prodrive/atlas: add unique DIMM locators in smbios type17 This patch adds unique device-locators, bank-locators and asset-tags to the smbios type17 tables by making use of a DIMMs controller-ID. This way we avoid name clashes when, for example, two DIMMs share the same channel-ID and DIMM-ID but have a distinct controller-ID.
