[PATCH RFC] misc/at24: distinguish between eeprom and fram chips
From: Lars Poeschel

I wanted to use a fm24c04 i2c fram chip with linux. I grepped the source
and found nothing. I later found that my chip can be handled by at24
eeprom driver. It creates a sysfs file called eeprom to read from and
write to the chip. Userspace has no chance to distinguish if it is
writing an eeprom or a fram chip.
I present this patch for 3 reasons:
1. For other people grepping finding a little more reference.
2. For userspace being able to distinguish eeprom and fram.
3. Raising the bytes per write for fram chips.
What do you kernel developers think ?
