No, this is not possible.
You can use the LCD, but as output channel only. There is no way to take input from a LCD display.
any one please tell me what changes I have to do in the u-boot to provide the console on LCD.Also please tell me if there is any interface for LCD already present in the u-boot
Yes, there are several graphics controllers that are well supported in U-Boot, even with advanced features like splash screen support.
Also note that U-Boot supports a netconsole interface so you could communicate over UDP with your target board.
