I'd prefer uint8_t *addr.  Both are the same, but the term "char"
mnemonically refers to a character you can display, while "uint8_t"
rather means a small integer type.  Also, since C99 now standardizes
integer types of certain bit width, we can give a good example for
what is preferable over all those home-brewn "u8" etc. data types.

Or, just use "void *".  In particular for eeprom_read_block(), this
would allow passing the address of a structure without any typecast.

Maybe uint8_t * for the single-byte operations, and void * for the
block operation(s)?
