  layer with the flash_hw_if structure. This structure has
  function pointers and other fields.
The attachment can be done by calling
    flash_attach_mi() with this structure and the
    device's device_t as an argument. Return value is the
    flash layer device. The flash_interface structure is
    shown below.
struct flash_interface {
	int (*erase) (device_t, struct flash_erase_instruction *);
	int (*read) (device_t, off_t, size_t, size_t *, uint8_t *);
	int (*write) (device_t, off_t, size_t, size_t *, const uint8_t *);
	int (*block_markbad)(device_t, uint64_t);
	int (*block_isbad)(device_t, uint64_t);
	int (*sync) (device_t);
	int (*submit)(device_t, struct buf *);
