u-boot compilation fails for smdk5250 when we deselect CONFIG_LCD from the main config file.
Following error was observed: drivers/video/libvideo.o: In function `exynos_lcd_init': /home/ajay/u-boot-samsung/drivers/video/exynos_fb.c:68: undefined reference to `lcd_set_flush_dcache'
This is because exynos video drivers have dependency on CONFIG_LCD.
