Subject: [1/1] omap3: Add macros for comparing si revision
Date: Fri, 08 Jan 2010 15:26:15 -0000
From: Sanjeev Premi <premi@ti.com>
X-Patchwork-Id: 71802
Message-Id: <1262964375-21873-1-git-send-email-premi@ti.com>
To: linux-omap@vger.kernel.org
Cc: Sanjeev Premi <premi@ti.com>
This patch adds verbose macros for comparing silicon
revision bits. Current mechanism of comparing complete
'omap_revision' does not work/ represent the multiple
processors, and their revisions.
