[U-Boot-Users] Are there any instructions how to compile U-boot for ixp425 target?

So what changes exactly were necessary? This might help others.

You have to match at least the PHY addresses to your board. And regarding the 
microcode version: The last version I tested successfully with, was version 
2.0. So you might want to download this one and give it a try.

Yes, that's correct. You have to configure the MAC addresses (ethaddr, 
eth1addr) and reset the board for the changes to take effect.

Please only use such hardcoded MAC addresses for test purposes!

Are you PHY addresses setup correctly? Something like this:

/*
 * Ethernet
 */
#define CONFIG_IXP4XX_NPE       1       /* include IXP4xx NPE support   */
#define CONFIG_NET_MULTI        1
#define CONFIG_PHY_ADDR         16      /* NPE0 PHY address             */
#define CONFIG_HAS_ETH1
#define CONFIG_PHY1_ADDR        18      /* NPE1 PHY address             */
#define CONFIG_MII              1       /* MII PHY management           */
#define CFG_RX_ETH_BUFFER       16      /* Number of ethernet rx buffers & 
descriptors */
