Many boards do not use all selected framebuffer depth configurations, for such boards there is some unused code in video and console uclass routines. Make depth specific code optional to avoid dead code and slightly reduce binary size. Also make ANSI code optional for the same reason. When i.e. using only VIDEO_BPP16 the code size shrinks (below values when using gcc-7.3.0): $ ./tools/buildman/buildman -b video-wip -sS wandboard ... 01: Merge git://git.denx.de/u-boot-sh 02: video: add guards around 16bpp/32bbp code 03: video: make BPP and ANSI configs optional arm: (for 1/1 boards) all -776.0 bss -8.0 text -768.0 Signed-off-by: Anatolij Gustschin <agust@denx.de> Tested-by: Eugen Hristev <eugen.hristev@microchip.com> Tested-by: Patrice Chotard <patrice.chotard@st.com> Tested-by: Steffen Dirkwinkel <s.dirkwinkel@beckhoff.com>
