The eeprom.txt file in the bindings directory actually describes the bindings for at24. There's a patch[1] from Wolfram waiting for Rob's ack that renames it to at24.txt. I hope that clears any confusion. @Sven: please split the patch into two: one for bindings and one for code. As for the name: I would change it to at24,no-read-rollover and remove the fragment saying it's only supported in at24 - as I said: this file only concerns at24 and will be renamed. > > Aren't there really other chips which need this?
