From a1dfe9c7c9b780865f7a847d3a12fe9214005a58 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Thu, 7 Oct 2010 17:39:03 +1000 Subject: [PATCH] fbdev/xilinxfb: Microblaze driver support DCR bus is natively used for PowerPC. Microblaze has no infrastructure for compile DCR that's why is necessary to exclude it. Signed-off-by: Michal Simek Acked-by: Grant Likely CC: Andrei Konovalov CC: "David S.
