Subject: [PATCH 05/11] intel_scu_ipc: Use the new cpu identification function
Date: Mon, 26 Jul 2010 10:03:58 +0100 [thread overview]
Message-ID: <20100726090337.12329.6969.stgit@localhost.localdomain> (raw)
In-Reply-To: <20100726090031.12329.53555.stgit@localhost.localdomain>
This provides an architecture level board identify function to replace the
cpuid direct usage
