From ad0d73b324dbc9e5b987fbda08ceb523fbeb0a9f Mon Sep 17 00:00:00 2001 From: Toshi Kani Date: Wed, 9 May 2018 16:20:30 -0600 Subject: [PATCH] EDAC, ghes: Add DDR4 and NVDIMM memory types The ghes_edac driver obtains memory type from SMBIOS type 17, but it does not recognize DDR4 and NVDIMM types. Add support of DDR4 and NVDIMM types. NVDIMM type is denoted by memory type DDR3/4 and non-volatile.
