I am just guessing on the usage too, but I assume it is for memory 
alignment for other types of nvmem devices that only read words (2, 4 or 
8 bytes) at a time. I don't see anything in the at24 code that says we 
can't read any arbitrary starting I2C register, so I don't think we 
should have any problems.

Microchip 24FC128

No and no.
