EEPROM driver device initialization priority. This initialization
priority is used unless the driver implementation has its own
initialization priority.

Size of the buffer used for EEPROM read/write commands in
the EEPROM shell.

This is an emulator for the Atmel AT24 series of I2C-attached EEPROMs.
At present it only supports 8-bit addressing. The size of the EEPROM
is given by the 'size' property. See the binding for further details.
