From 94e0c6ca37b0c26338ba2a69b11da777965839be Mon Sep 17 00:00:00 2001 From: Paul Menzel Date: Mon, 27 Feb 2017 01:01:55 +0100 Subject: [PATCH] UPSTREAM: cpu/intel/model_6{e,f}x: Unify init files The init files for the Core Duo and Core 2 Duo are very similar. Reduce the differences, by using the same order for the include statements, the same blank lines, and the same comments.
