From 8fa624784e3d78e67cf7b4e0e72cb2208c399f0f Mon Sep 17 00:00:00 2001 From: Timothy Pearson Date: Mon, 9 Jan 2017 14:19:37 -0600 Subject: [PATCH] amd/mct/ddr3: Correctly program maximum read latency The existing code inadvertently calculated the maximum read latency for nonexistent channel 2 instead of for channels 0 and 1 as intended. Fix the calls to the maximum read latency training function.
