This patch adds an option to skip the video initialization on for all video drivers. This is needed for the CPCI750 which can be built as CPCI host and adapter/target board. And the adapter board can't access the video cards located on the CompactPCI bus.
Signed-off-by: Stefan Roese sr@denx.de Cc: Anatolij Gustschin agust@denx.de --- This patch replaces the previous one [video: ct6900: Add an option to skip video initialization]. The test is now moved out of the ct6900 file into the generic video init routine drv_video_init() as suggested by Anatolij.
Thanks, Stefan
