From e6649cc62949f1ed473bf1131fa425cfe72d3f64 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 24 Sep 2010 11:53:52 -0300 Subject: i7300_edac: Properly initialize per-csrow memory size Due to the current edac-core limits, we cannot represent a per-channel memory size, for FB-DIMM drivers. So, we need to sum-up all values for each slot, in order to properly represent the total amount of memory found by the i7300 driver.
