From 315bb30cd764a3f57cc6ce36a481e7361ac3a0c0 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Thu, 24 Oct 2013 14:55:42 -0500 Subject: baytrail: get rid of global microcode_ptr A global microcode_ptr was added when doing the MP development work. However, this is unnecessary as the pattrs structure already contains the pointer. Use that instead. BUG=chrome-os-partner:22862 BRANCH=None TEST=Built and booted. Microcode still being loaded correctly.
