[U-Boot-Users] "Partitioning" EEPROM

Hi list ;-),

I have an 24c64 EEPROM wired via i2c on an embedded device. I want to "partition" the EEPROM so that I have one node /dev/EEPROM/0 for system and environment stuff, and another entry /dev/EEPROM/1 for custom data for the application. I thought to write a driver for the second device and limit the bounds of the first one. But I guess that would be bad practice when concurrent access to the EEPROM happens. The other thing I think of is to have the EEPROM as MTD device(s). Would this be viable (I mean if it doesn't involve too much code changes)?

What would be a good way to achieve this?
