From 1a0226f4f2859fc06743e6958243d6a9d3f9ca8d Mon Sep 17 00:00:00 2001 From: Kyungmin Park Date: Thu, 6 Mar 2008 09:35:50 +0900 Subject: [PATCH] ARM: OMAP: Add IDCODE revision to system_rev In previous kernel there's IDCODE revision. But recently it was removed. I hope it want to add this one to distinguish board revision. Are there another way to combine Silicon revision with IDCODE one? Any comments are welcome.
