From 25a9b76597fafbbf688dd4473cb910568deb2b0c Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Tue, 25 Jul 2017 19:26:23 +0200 Subject: parisc: Add function to return DIMM slot of physical address Add a firmware wrapper function, which asks PDC firmware for the DIMM slot of a physical address. This is needed to show users which DIMM module needs replacement in case a broken DIMM was encountered.
