The address is obviously a ram source/destination address. I vote for an offset in bytes and a count in bytes. If the offset is not an appropriate sector boundary, it is an error. The count can be a partial sector without problems. Having the offset and count in different units is confusing IMHO, so bytes for both. Also, Mike, I assume you will also add a module similar to env_eeprom.c to support environment in spiflash?
