-- * present on the device, it automatically appends all of them to the volume
-- * (the physical eraseblocks reserved for bad eraseblocks handling and other
-- * reserved physical eraseblocks are not taken). So, if there is a volume with
-- * the %UBI_VTBL_AUTORESIZE_FLG flag set, the amount of available logical
-- * eraseblocks will be zero after UBI is loaded, because all of them will be
-- * reserved for this volume. Note, the %UBI_VTBL_AUTORESIZE_FLG bit is cleared
-- * after the volume had been initialized.
-- *
-- * The auto-resize feature is useful for device production purposes. For
-- * example, different NAND flash chips may have different amount of initial bad
-- * eraseblocks, depending of particular chip instance. Manufacturers of NAND
-- * chips usually guarantee that the amount of initial bad eraseblocks does not
-- * exceed certain percent, e.g. 2%. When one creates an UBI image which will be
-- * flashed to the end devices in production, he does not know the exact amount
-- * of good physical eraseblocks the NAND chip on the device will have, but this
-- * number is required to calculate the volume sized and put them to the volume
-- * table of the UBI image. In this case, one of the volumes (e.g., the one
-- * which will store the root file system) is marked as "auto-resizable", and
-- * UBI will adjust its size on the first boot if needed.
-- *
-- * Note, first UBI reserves some amount of physical eraseblocks for bad
-- * eraseblock handling, and then re-sizes the volume, not vice-versa. This

-- * struct ubi_vid_hdr - on-flash UBI volume identifier header.
-- * @magic: volume identifier header magic number (%UBI_VID_HDR_MAGIC)
-- * @version: UBI implementation version which is supposed to accept this UBI
-- * image (%UBI_VERSION)
-- * @vol_type: volume type (%UBI_VID_DYNAMIC or %UBI_VID_STATIC)
-- * @copy_flag: if this logical eraseblock was copied from another physical
-- * eraseblock (for wear-leveling reasons)
-- * @compat: compatibility of this volume (%0, %UBI_COMPAT_DELETE,
-- * %UBI_COMPAT_IGNORE, %UBI_COMPAT_PRESERVE, or %UBI_COMPAT_REJECT)
-- * @vol_id: ID of this volume
-- * @lnum: logical eraseblock number
-- * @leb_ver: version of this logical eraseblock (IMPORTANT: obsolete, to be
-- * removed, kept only for not breaking older UBI users)
-- * @data_size: how many bytes of data this logical eraseblock contains
-- * @used_ebs: total number of used logical eraseblocks in this volume
-- * @data_pad: how many bytes at the end of this physical eraseblock are not
-- * used
-- * @data_crc: CRC checksum of the data stored in this logical eraseblock
-- * @padding1: reserved for future, zeroes
-- * @sqnum: sequence number
-- * @padding2: reserved for future, zeroes
-- * @hdr_crc: volume identifier header CRC checksum
-- *
-- * The @sqnum is the value of the global sequence counter at the time when this
-- * VID header was created. The global sequence counter is incremented each time
-- * UBI writes a new VID header to the flash, i.e. when it maps a logical
-- * eraseblock to a new physical eraseblock. The global sequence counter is an
-- * unsigned 64-bit integer and we assume it never overflows. The @sqnum
-- * (sequence number) is used to distinguish between older and newer versions of
-- * logical eraseblocks.
-- *
-- * There are 2 situations when there may be more then one physical eraseblock
-- * corresponding to the same logical eraseblock, i.e., having the same @vol_id
-- * and @lnum values in the volume identifier header. Suppose we have a logical
-- * eraseblock L and it is mapped to the physical eraseblock P.
-- *
-- * 1. Because UBI may erase physical eraseblocks asynchronously, the following
-- * situation is possible: L is asynchronously erased, so P is scheduled for
-- * erasure, then L is written to,i.e. mapped to another physical eraseblock P1,
-- * so P1 is written to, then an unclean reboot happens. Result - there are 2
-- * physical eraseblocks P and P1 corresponding to the same logical eraseblock
-- * L. But P1 has greater sequence number, so UBI picks P1 when it attaches the
-- * flash.
-- *
-- * 2. From time to time UBI moves logical eraseblocks to other physical
-- * eraseblocks for wear-leveling reasons. If, for example, UBI moves L from P
-- * to P1, and an unclean reboot happens before P is physically erased, there
-- * are two physical eraseblocks P and P1 corresponding to L and UBI has to
-- * select one of them when the flash is attached. The @sqnum field says which
-- * PEB is the original (obviously P will have lower @sqnum) and the copy. But
-- * it is not enough to select the physical eraseblock with the higher sequence
-- * number, because the unclean reboot could have happen in the middle of the
-- * copying process, so the data in P is corrupted. It is also not enough to
-- * just select the physical eraseblock with lower sequence number, because the
-- * data there may be old (consider a case if more data was added to P1 after
-- * the copying). Moreover, the unclean reboot may happen when the erasure of P
-- * was just started, so it result in unstable P, which is "mostly" OK, but
-- * still has unstable bits.
-- *
-- * UBI uses the @copy_flag field to indicate that this logical eraseblock is a
-- * copy. UBI also calculates data CRC when the data is moved and stores it at
-- * the @data_crc field of the copy (P1). So when UBI needs to pick one physical
-- * eraseblock of two (P or P1), the @copy_flag of the newer one (P1) is
-- * examined. If it is cleared, the situation* is simple and the newer one is
-- * picked. If it is set, the data CRC of the copy (P1) is examined. If the CRC
-- * checksum is correct, this physical eraseblock is selected (P1). Otherwise
-- * the older one (P) is selected.
-- *
-- * Note, there is an obsolete @leb_ver field which was used instead of @sqnum
-- * in the past. But it is not used anymore and we keep it in order to be able
-- * to deal with old UBI images. It will be removed at some point.
-- *
-- * There are 2 sorts of volumes in UBI: user volumes and internal volumes.
-- * Internal volumes are not seen from outside and are used for various internal
-- * UBI purposes. In this implementation there is only one internal volume - the
-- * layout volume. Internal volumes are the main mechanism of UBI extensions.
-- * For example, in future one may introduce a journal internal volume. Internal
-- * volumes have their own reserved range of IDs.
-- *
-- * The @compat field is only used for internal volumes and contains the "degree
-- * of their compatibility". It is always zero for user volumes. This field
-- * provides a mechanism to introduce UBI extensions and to be still compatible
-- * with older UBI binaries. For example, if someone introduced a journal in
-- * future, he would probably use %UBI_COMPAT_DELETE compatibility for the
-- * journal volume. And in this case, older UBI binaries, which know nothing
-- * about the journal volume, would just delete this volume and work perfectly
-- * fine. This is similar to what Ext2fs does when it is fed by an Ext3fs image
-- * - it just ignores the Ext3fs journal.
-- *
-- * The @data_crc field contains the CRC checksum of the contents of the logical
-- * eraseblock if this is a static volume. In case of dynamic volumes, it does
-- * not contain the CRC checksum as a rule. The only exception is when the
-- * data of the physical eraseblock was moved by the wear-leveling unit, then
-- * the wear-leveling unit calculates the data CRC and stores it in the
-- * @data_crc field. And of course, the @copy_flag is %in this case.
-- *
-- * The @data_size field is used only for static volumes because UBI has to know
-- * how many bytes of data are stored in this eraseblock. For dynamic volumes,
-- * this field usually contains zero. The only exception is when the data of the
-- * physical eraseblock was moved to another physical eraseblock for
-- * wear-leveling reasons. In this case, UBI calculates CRC checksum of the
-- * contents and uses both @data_crc and @data_size fields. In this case, the
-- * @data_size field contains data size.
-- *
-- * The @used_ebs field is used only for static volumes and indicates how many
-- * eraseblocks the data of the volume takes. For dynamic volumes this field is
-- * not used and always contains zero.
-- *
-- * The @data_pad is calculated when volumes are created using the alignment
-- * parameter. So, effectively, the @data_pad field reduces the size of logical
-- * eraseblocks of this volume. This is very handy when one uses block-oriented
-- * software (say, cramfs) on top of the UBI volume.

-- *
-- * The volume table records are stored in the volume table, which is stored in

-- * The @upd_marker flag is used to implement volume update. It is set to %1

-- *
-- * The @alignment field is specified when the volume is created and cannot be
-- * later changed. It may be useful, for example, when a block-oriented file
-- * system works on top of UBI. The @data_pad field is calculated using the
-- * logical eraseblock size and @alignment. The alignment must be multiple to the
-- * minimal flash I/O unit. If @alignment is 1, all the available space of
-- * the physical eraseblocks is used.
-- *
-- * Empty records contain all zeroes and the CRC checksum of those zeroes.
