Can't "up" my eth0

[Denny]

Hi,
 
   I am now succefully to bring up my kernel on my PPC440GP custom board, but I failed to up my eth0, the eth0 is link down after the kernel is booting up.
   
   There is no effect, after the command ifconfig eth0 up.
   
   Can anyone tell me what may be the root case, and what reason may cause the eth0 unstable, thanks a lot.
 
    below is my log:
PPC 4xx OCP EMAC driver, version 3.53
mal0: initialized, 4 TX channels, 2 RX channels
zmii0: bridge in RMII mode
eth0: emac0, MAC 00:01:02:54:12:47
eth0: found Generic MII PHY (0x01)
emac1: can't find PHY!
