[U-Boot-Users] 440GP and the MII mode

Hello all,

I understand that the ebony board is set to RMII mode (for the ethernet PHY
device) and U-boot also configures the ZMII0_FER to the RMII mode.  I
have a custom 440-GP based board, which should operate in the MII
mode. Is it enough if I configure the ZMII0_FER register to the MII
mode (in the file: cpu/ppc4xx/4xx_enet.c)?

 Are there other places in the U-boot code that might need change?
I'm currently reading through the source code to figure this out, but
I wanted to get a heads-up from others.

Thanks,
G.Sibi
