The M24M01-D* eeproms are in effect 2 eeproms under 2 I2C addresses:
1. a standard 1Mbit eeprom (driver model 24c1024 is working)
2. a 256 Byte "ID page" that is a write lockable page.
As the ID page demands 2 byte addresses, the 24c02 driver model
can not be used.
I was thinking about not to pollute the name space of chip names
with a made up name that is not the name of a real chip.
I would propose to name it "24cb02", thus making clear
that we have a kind of 24c02 but with 2 byte address.
(The "b" ist meant to say this)
