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 usage of the first one. But I guess that would be bad practice when concurrent access to the EEPROM happens.
What would be a good way to achieve this? Do you think it's possible at all?

If you use MTD devices, you can have /dev/mtd/0 as the whole EEPROM, /dev/mtd/1 as the first partition, /dev/mtd/2 as the second partition and so on.
Take a look at it: Memory Technology Devices They are eg. used in the D-Box2, where the complete system sits on an 8M flash chip; there are different partitions (booloader, / (ro-fs), /var (rw-fs) and so on.
