* Patch by Sean Chang, 9 Aug 2004:

- Added I2C support for ML300.
  - Added support for ML300 to read out its environment information
    stored on the EEPROM.
  - Added support to use board specific parameters as part of
    U-Boot's environment information.
  - Updated MLD files to support configuration for new features
    above.

* Patches by Travis Sawyer, 5 Aug 2004:
  - Remove incorrect bridge settings for eth group 6
  - Add call to setup bridge in ppc_440x_eth_initialize
  - Fix ppc_440x_eth_init to reset the phy only if its the
    first time through, otherwise, just check the phy for the
    autonegotiated speed/duplex.  This allows the use of netconsole
  - only print the speed/duplex the first time the phy is reset.
