From 97b3ecb575a92fa34c1765229dbc06f2b662f139 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 9 Apr 2008 04:20:57 -0500 Subject: [PATCH] 85xx: Fix detection of MP cpu spin up We were looking at the wrong memory offset to determine of a secondary cpu had been spun up or not. Also added a warning message if the all the secondary cpus we expect don't spin up.
