Use automatic base address assignment.

The address range is determined by the width of the address signal of the slave port of the component. The base address is up to you to determine. You can autoassign it or manually give it one. I assume you are writing Nios II application code around this so be sure to include the driver in order to talk to it. The driver uses a file called "system.h" in your BSP project to find out where the LCD lives in your address map. So at the end of the day it doesn't matter where you place the base address of the LCD if you use the software support files correctly they'll match up the address correctly for you. I recommend taking a look at the "board_diag" software example to learn more since it uses the character LCD too.
