From 4f9bf7e2fb7035725c2899db0d00d77007d9113c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Mon, 9 Sep 2013 09:23:19 +0300 Subject: AMD hudson yangtze: Fix corruption of a global ramstage variable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A late for loop may reference over the current array allocation and corrupt an unrelated global variable. As a quick fix bumb the size of the array allocation uniformly to 6. We missed these boards for commit 9c7d73ca because the arrays had been renamed.
