* 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.
