I lost the original mail where Ludovic said:

"I tested it quickly on a sama5d2 xplained board: I used an i2c-gpio
master and the eeprom driver. It works pretty well. I tried to increase
the size of the eeprom by adding:
+ { "slave-24c64", 65536 / 8 },"

That won't work. The comment at the beginning of the file says:

 * ... It is prepared to simulate bigger EEPROMs with an internal 16 bit
 * pointer, yet implementation is deferred until the need actually arises.

So,  no EEPROMs > 256 byte for now.

BTW maybe I asked already and forgot: is this IP core capable of being
master and slave on the same bus?
