Note, you already need 2 eeproms, one on the CPU card and one on the carrier
board.  I believe they are supposed to be on different I2C busses?

However, any time you're going to put user-data in a location, why not use
mass-storage?  Why put encryption keys into EEPROM?  Either they should be
bound to the device (use a ROM seperate from EOMA68 device-tree) or they
should be mobile (store on HDD/SSD)
