the following patch was just integrated into master: commit 74b13a56166649967a3e9ab0e4ea5c68b518c6b2 Author: Timothy Pearson email@example.com Date: Sat Oct 31 15:00:23 2015 -0500
mainboard/asus/kfsn4-dre_k8: Fix broken dual CPU package support
The existing KFSN4-DRE support hung during ramstage while initializing AP #3 if a second CPU package was installed. After analyzing the Sun Ultra 40 M2 support code it became apparent that the K8 code cannot function correctly if sequential RAM training is disabled, and that there were a few other missing calls. This patch adds the missing calls, adjust the CAR space to an appropriate level, and explicitly defines the link numbers and connections in devicetree.cb
TEST: Booted ASUS KFSN4-DRE with 2x Opteron 8222 installed.
