[U-Boot-Users] MPC83xx Ethernet bug
Just tried to move my 83xx based board to latest u-boot and noticed an old problem. u-boot tries to bring up the ethernet at startup, not the first time it is used:

Looked into uec_phy.c driver to find the source of: read wrong value : mii_id 3,mii_reg 3, base e0102320 I don't have PHYs in my system and I wonder if there is a way to avoid this message?
Also, there is a udelay(100000) in that function, uec_read_phy_reg(), that slows it down alot. Is that really needed?

I don't know why the calls to init_phy() and phy_change() are in uec_initialize() instead of uec_init(). Moving them should at least prevent this stuff at boot-up.
