In order to get LCD console, we need to enable half word swap feature of FIMD and use 16 BPP. LCD console and proprietary Logo cannot be used simultaneously. We use "logo_on" field inside vidinfo_t structure to decide whether user wants Logo or Console. Define CONFIG_CMD_BMP and make logo_on = 1 to get Logo on screen. Use logo_on = 0 to get output console on LCD.
