From 54cd1dee8f9537c2e3d5bfe2029bf31b2b1cf2f3 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Tue, 8 May 2012 03:40:49 +0000 Subject: mx53loco: Add CONFIG_REVISION_TAG FSL 2.6.35 kernel assumes that the bootloader passes the CONFIG_REVISION_TAG information. The kernel uses this data to distinguish between Dialog versus mc34708 based boards, and also to distinguish between revA and revB of the mc34708 based boards.
