What's the recommended way to work with i2c_eeprom_partitions?

I have them probed but curious how I should work with them.
 i2c           1  [ + ]   i2c_mux_bus_drv       |   |       |--
i2c at ff030000->i2c-mux at 74->i2c at 0
 i2c_eeprom    0  [ + ]   i2c_eeprom            |   |       |   `-- eeprom at 54
 i2c_eeprom    1  [   ]   i2c_eeprom_partition  |   |       |
|-- board-sn at 0
 i2c_eeprom    2  [   ]   i2c_eeprom_partition  |   |       |
|-- eth-mac at 20
 i2c_eeprom    3  [   ]   i2c_eeprom_partition  |   |       |
|-- board-name at d0
 i2c_eeprom    4  [   ]   i2c_eeprom_partition  |   |       |
`-- board-revision at e0

Is there any u-boot command for reading values from these partitions?
Or are you just referencing them by
fdt_path_offset/uclass_get_device_by_of_offset?

Thanks,
Michal
