From 14f88c43fcb7cee954648daeaba08b8e881ec01b Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Mon, 29 Nov 2010 21:17:37 +0100 Subject: video: move fsl_diu_fb driver to drivers/video Since the driver is used not only on Freescale boards, we move it to a common place for video drivers as suggested by Wolfgang. The patch also cleans up the top level Makefile.
