From 754f8cb68978efd31ddea73fa731e4e511bdd873 Mon Sep 17 00:00:00 2001 From: Manjunath Hadli Date: Mon, 10 Oct 2011 21:06:38 +0000 Subject: [PATCH] da850evm: pass board revision info to kernel there are two boards based on da850 SOC - OMAP-L138 and AM18x. In order to differentiate between these two boards, revision id is passed to kernel via second byte of ATAG_REVISION.
