[U-Boot-Users] mx21ads patch

[Livio Tenze]

Hi all!!
I am trying to use the mx21ads patch for the u-boot-1.1.3 but I have 
some problems in configuring the ethernet adapter cs8900: when I 
properly set the related definitions
/*
 *  CS8900 Ethernet drivers
 */
#define CONFIG_DRIVER_CS8900    1    /* we don't have a CS8900 on-board */
#define CS8900_BASE        0x15000300
#define CS8900_BUS16        1    /* the Linux driver does accesses as 
shorts */

an error occurs at the compile-time (unreferenced cs8900_get_enetaddr or 
something similar).
How can I correctly set the ethernet adapter?
May you help me?

Thanks in advance!
Livio
