From 121ef60666e59656a74044c7f21f52b3bb849b1d Mon Sep 17 00:00:00 2001 From: Timothy Pearson Date: Sat, 8 Aug 2015 02:40:58 -0500 Subject: northbridge/amd/amdfam10: Fix invalid NUMA table The existing code generated an invalid NUMA table that was rejected by Linux, leading to poor resource allocation. This was due to system MMIO resources being inserted into the table when the table should only contain DRAM resources. Do not include system MMIO resources (i.e. resources with an index less than 0x10) in the NUMA table.
