Subject: video: add guards around 16bpp/32bbp code
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ca5655d8006cfbaa4ff8ff450e4a5931e57fe050;p=u-boot.git

video: add guards around 16bpp/32bbp code

Many boards use only single depth configuration, for such boards
there is some unused code in video and console uclass routines.
Add guards to avoid dead code.
