Add i2c eeprom #106

Closed jordens closed 2 years ago

To identify Pounder and distinguish it from other mezzanines, we should add an eeprom (Driver already has it) on the I2C bus. Nominated for v1.2 if it's not too late.

We could use the different i2c gpio extender as an indicator. But that's obviously a shortsighted idea as nothing prevents other mezzanines from using those as well.

we can use another switch as a revision indicator (4 bits) and board type indicator (another 4 bits)

On the other side, it would be good to do it as on the Driver mezzanine
