15 Superblock locations may differ for MTD and block devices. On MTD the
16 first non-bad block contains a superblock in the first 4096 Bytes and
17 the last non-bad block contains a superblock in the last 4096 Bytes.
18 On block devices, the first 4096 Bytes of the device contain the first
19 superblock and the last aligned 4096 Byte-block contains the second
