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.

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.
