From 5ca95c48f1bd006d1aafe2f8bf1a859262d6d7b1 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Fri, 3 Aug 2007 10:16:29 +0900 Subject: [PATCH] sh: fix cf support on r2d boards This patch makes sure cf support is enabled on R2D-PLUS but disabled on R2D-1. Without this fix R2D-1 boards hang on bootup.
