From 522487a05d2beef4f355dc7c47af08108496b244 Mon Sep 17 00:00:00 2001 From: Jacob Pan <jacob.jun.pan@intel.com> Date: Thu, 11 Jun 2009 20:34:47 -0700 Subject: [PATCH] x86/boot: adding hw subarch ID for Moorestown
x86 bootprotocol 2.07 has introduced hardware_subarch ID in the boot parameters provided by FW. We use it to identify Moorestown platforms.
The subarchitecture ID will help select a set of platform features and x86_quirks.
