For flash devices either NOR type or NAND type. You can only turn
each bits for 1 state to 0 by a "write" command. If you want to
turn a bit from 0 to 1, you have to erase the device. Each device
has its onw minimal erase size i.e. if you want to erase onely 1 byte
in a erase region, you have to erase the whole erase region.
The nftl_format is used somewht like "low-level" format for old
