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

My board uses external uart for console so most (if not all) changes are
because of that. I can try to get the differences to latest version from
git, but I'm not expert in git.

Yes, the PHY addresses are set correctly. At least I think they should
be since I checked them from the schematics. I also checked from the
older version and it seems that the PHY addresses are the same.

Of course, but why doesn't those go to environment variables plus the
lines you deleted? In version 1.1.2 default environment contains those
values, but not in the current one. Maybe something has changed in
environment setup?

Yes,

/*
 * Ethernet
 */
#define CONFIG_IXP4XX_NPE	1	/* include IXP4xx NPE support */
#define CONFIG_NET_MULTI	1
#define CONFIG_PHY_ADDR	0	/* NPE0 PHY address	        */
#define CONFIG_HAS_ETH1
#define CONFIG_PHY1_ADDR	1	/* NPE1 PHY address
*/
#define CONFIG_MII		1	/* MII PHY management
*/
#define CFG_RX_ETH_BUFFER	16	/* Number of ethernet rx buffers
& descriptors */

First PHY chip has all address pins grounded and second PHY has A0 up
and all the other to ground so that way I figure out the addresses.
Checked from old code too and it seems that addresses are 0 and 1.

I'll download the older version of Microcode and try with it, but if
that doesn't help then I'm (again) kind of stuck.
