From: Anatolij Gustschin Date: Mon, 29 Nov 2010 20:17:37 +0000 (+0100) Subject: video: move fsl_diu_fb driver to drivers/video X-Git-Tag: v2010.12-rc3~29^2~1 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=14f88c43fcb7cee954648daeaba08b8e881ec01b;p=u-boot 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.
