What U-Boot version do you use?
U-Boot 1.1.4-geb3fa991 (Feb 21 2013 - 10:11:04) (output of version command)
Very old, ;-).
This video_set_lut() function is only needed if you use 8 bits per pixel frame buffer.
So can I comment it out, (or) just make a dummy call and dummy return from it. It wont affect my character(text) rendering on the display, correct ?
yes, just provide a dummy video_set_lut(). If you do not use the GDF__8BIT_INDEX framebuffer format, the rendering will work.
My last question, the board_video_init() function just initializes the board in display/video mode. For example if I have a GPIO to switch b/w command and video modes and a GPIO to switch on the LCD, etc., I'll have to do all such functions in it.
But if all of those are already done, I can just return a dummy from the function ?
Yes. If board specific video initialisation is done elsewhere the board_video_init() can be a dummy function. Some video drivers expect board_video_init() to return frame buffer base address but i.e. in omap3 driver it returns 0 for successful video init or an error code in case the board specific video init fails, thus preventing further initialisation in the cfb_console driver.
