+## EEPROM (I2C slave simulated EEPROM)
+The FS GPON-ONU-34-20BI does not have a physical EEPROM, the Falcon SOC emulates an EEPROM by exposing it on the I2C interface as required by the SFF-8472 specification.
+
+On the I2C interface there will be two memories of 256 bytes each at the addresses `1010000X (A0h)` and `1010001X (A2h)`, however in reality the memory available from the emulated EEPROM will be 640 bytes each but only the first 256 bytes will be exposed in the I2C interface.
+
+The FS GPON-ONU-34-20BI stores the content of the emulated EEPROM in U-Boot env variables to restore it after a reboot:
+
+- `EEPROM0 (A0h)` stored in U-Boot env variable `sfp_a0_low_128`
+- `EEPROM1 (A2h)` stored in U-Boot env variable `sfp_a2_info`
