This is not going to happen, sorry. "eeprom" is a legacy driver and we
certainly don't want to enhance it in any way. The "at24" driver is
much easier to extend as it was designed that way from the ground up.
You can add a SFP EEPROM type to it (whatever it is) and have the
driver automatically set the access to read-only and the caching
strategy for each part of the EEPROM.

I'm curious, why do you insist on using the eeprom driver?
