6 +config BOARD_ATNGW100_I2C_GPIO
7 + bool "Use GPIO for i2c instead of built-in TWI module"
8 + help
9 + The driver for the built-in TWI module has been plagued by
10 + various problems, while the i2c-gpio driver is based on the
11 + trusty old i2c-algo-bit bitbanging engine, making it work
12 + on pretty much any setup.
13 +
14 + Choose 'Y' here if you're having i2c-related problems and
15 + want to rule out the i2c bus driver.

13537 + * Many 32-bit Atmel SOCs include one or more TC blocks, each of which holds

13540 + * may be shared by the whole TC block.
13541 + *
13542 + * These TC blocks may have up to nine external pins: TCLK0..2 signals for
13543 + * clocks or clock gates, and per-timer TIOA and TIOB signals used for PWM
13544 + * or triggering. Those pins need to be set up for use with the TC block,
13545 + * else they will be used as GPIOs or for a different controller.
13546 + *

13896 - * The auto-resize feature is useful for device production purposes. For
13897 - * example, different NAND flash chips may have different amount of initial bad
13898 - * eraseblocks, depending of particular chip instance. Manufacturers of NAND
13899 - * chips usually guarantee that the amount of initial bad eraseblocks does not
13900 - * exceed certain percent, e.g. 2%. When one creates an UBI image which will be
13901 - * flashed to the end devices in production, he does not know the exact amount
13902 - * of good physical eraseblocks the NAND chip on the device will have, but this
13903 - * number is required to calculate the volume sized and put them to the volume
13904 - * table of the UBI image. In this case, one of the volumes (e.g., the one
13905 - * which will store the root file system) is marked as "auto-resizable", and
13906 - * UBI will adjust its size on the first boot if needed.
13907 - *
13908 - * Note, first UBI reserves some amount of physical eraseblocks for bad
13909 - * eraseblock handling, and then re-sizes the volume, not vice-versa. This
13910 - * means that the pool of reserved physical eraseblocks will always be present.

14000 - *
14001 - * The @sqnum is the value of the global sequence counter at the time when this
14002 - * VID header was created. The global sequence counter is incremented each time
14003 - * UBI writes a new VID header to the flash, i.e. when it maps a logical
14004 - * eraseblock to a new physical eraseblock. The global sequence counter is an
14005 - * unsigned 64-bit integer and we assume it never overflows. The @sqnum
14006 - * (sequence number) is used to distinguish between older and newer versions of
14007 - * logical eraseblocks.
14008 - *
14009 - * There are 2 situations when there may be more then one physical eraseblock
14010 - * corresponding to the same logical eraseblock, i.e., having the same @vol_id
14011 - * and @lnum values in the volume identifier header. Suppose we have a logical
14012 - * eraseblock L and it is mapped to the physical eraseblock P.
14013 - *
14014 - * 1. Because UBI may erase physical eraseblocks asynchronously, the following
14015 - * situation is possible: L is asynchronously erased, so P is scheduled for
14016 - * erasure, then L is written to,i.e. mapped to another physical eraseblock P1,
14017 - * so P1 is written to, then an unclean reboot happens. Result - there are 2
14018 - * physical eraseblocks P and P1 corresponding to the same logical eraseblock
14019 - * L. But P1 has greater sequence number, so UBI picks P1 when it attaches the
14020 - * flash.
14021 - *
14022 - * 2. From time to time UBI moves logical eraseblocks to other physical
14023 - * eraseblocks for wear-leveling reasons. If, for example, UBI moves L from P
14024 - * to P1, and an unclean reboot happens before P is physically erased, there
14025 - * are two physical eraseblocks P and P1 corresponding to L and UBI has to
14026 - * select one of them when the flash is attached. The @sqnum field says which
14027 - * PEB is the original (obviously P will have lower @sqnum) and the copy. But
14028 - * it is not enough to select the physical eraseblock with the higher sequence
14029 - * number, because the unclean reboot could have happen in the middle of the
14030 - * copying process, so the data in P is corrupted. It is also not enough to
14031 - * just select the physical eraseblock with lower sequence number, because the
14032 - * data there may be old (consider a case if more data was added to P1 after
14033 - * the copying). Moreover, the unclean reboot may happen when the erasure of P
14034 - * was just started, so it result in unstable P, which is "mostly" OK, but
14035 - * still has unstable bits.
14036 - *
14037 - * UBI uses the @copy_flag field to indicate that this logical eraseblock is a
14038 - * copy. UBI also calculates data CRC when the data is moved and stores it at
14039 - * the @data_crc field of the copy (P1). So when UBI needs to pick one physical
14040 - * eraseblock of two (P or P1), the @copy_flag of the newer one (P1) is
14041 - * examined. If it is cleared, the situation* is simple and the newer one is
14042 - * picked. If it is set, the data CRC of the copy (P1) is examined. If the CRC
14043 - * checksum is correct, this physical eraseblock is selected (P1). Otherwise
14044 - * the older one (P) is selected.
14045 - *
14046 - * Note, there is an obsolete @leb_ver field which was used instead of @sqnum
14047 - * in the past. But it is not used anymore and we keep it in order to be able
14048 - * to deal with old UBI images. It will be removed at some point.
14049 - *
14050 - * There are 2 sorts of volumes in UBI: user volumes and internal volumes.
14051 - * Internal volumes are not seen from outside and are used for various internal
14052 - * UBI purposes. In this implementation there is only one internal volume - the
14053 - * layout volume. Internal volumes are the main mechanism of UBI extensions.
14054 - * For example, in future one may introduce a journal internal volume. Internal
14055 - * volumes have their own reserved range of IDs.
14056 - *
14057 - * The @compat field is only used for internal volumes and contains the "degree
14058 - * of their compatibility". It is always zero for user volumes. This field
14059 - * provides a mechanism to introduce UBI extensions and to be still compatible
14060 - * with older UBI binaries. For example, if someone introduced a journal in
14061 - * future, he would probably use %UBI_COMPAT_DELETE compatibility for the
14062 - * journal volume. And in this case, older UBI binaries, which know nothing
14063 - * about the journal volume, would just delete this volume and work perfectly
14064 - * fine. This is similar to what Ext2fs does when it is fed by an Ext3fs image
14065 - * - it just ignores the Ext3fs journal.
14066 - *
14067 - * The @data_crc field contains the CRC checksum of the contents of the logical
14068 - * eraseblock if this is a static volume. In case of dynamic volumes, it does
14069 - * not contain the CRC checksum as a rule. The only exception is when the
14070 - * data of the physical eraseblock was moved by the wear-leveling unit, then
14071 - * the wear-leveling unit calculates the data CRC and stores it in the
14072 - * @data_crc field. And of course, the @copy_flag is %in this case.
14073 - *
14074 - * The @data_size field is used only for static volumes because UBI has to know
14075 - * how many bytes of data are stored in this eraseblock. For dynamic volumes,
14076 - * this field usually contains zero. The only exception is when the data of the
14077 - * physical eraseblock was moved to another physical eraseblock for
14078 - * wear-leveling reasons. In this case, UBI calculates CRC checksum of the
14079 - * contents and uses both @data_crc and @data_size fields. In this case, the
14080 - * @data_size field contains data size.
14081 - *
14082 - * The @used_ebs field is used only for static volumes and indicates how many
14083 - * eraseblocks the data of the volume takes. For dynamic volumes this field is
14084 - * not used and always contains zero.
14085 - *
14086 - * The @data_pad is calculated when volumes are created using the alignment
14087 - * parameter. So, effectively, the @data_pad field reduces the size of logical
14088 - * eraseblocks of this volume. This is very handy when one uses block-oriented
14089 - * software (say, cramfs) on top of the UBI volume.
