  • 83d290c56   SPDX: Convert all of our single license tags to Linux Kernel style ... Browse Code »
    56

    When U-Boot started using SPDX tags we were among the early adopters and
    there weren't a lot of other examples to borrow from. So we picked the
    area of the file that usually had a full license text and replaced it
    with an appropriate SPDX-License-Identifier: entry. Since then, the
    Linux Kernel has adopted SPDX tags and they place it as the very first
    line in a file (except where shebangs are used, then it's second line)
    and with slightly different comment styles than us.

    In part due to community overlap, in part due to better tag visibility
    and in part for other minor reasons, switch over to that style.

    This commit changes all instances where we have a single declared
    license in the tag as both the before and after are identical in tag
    contents. There's also a few places where I found we did not have a tag
    and have introduced one.

    mtd: nand: Rename nand.h into rawnand.h

    We are planning to share more code between different NAND based
    devices (SPI NAND, OneNAND and raw NANDs), but before doing that
    we need to move the existing include/linux/mtd/nand.h file into
    include/linux/mtd/rawnand.h so we can later create a nand.h header
    containing all common structure and function prototypes.

    58

    nand_info[] is now an array of pointers, with the actual mtd_info
    instance embedded in struct nand_chip.

    This is in preparation for syncing the NAND code with Linux 4.6,
    which makes the same change to struct nand_chip. It's in a separate
    commit due to the large amount of changes required to accommodate the
    change to nand_info[].

  • 004a1fdb4   nand: yaffs: Remove the "nand write.yaffs" command ... Browse Code »

    This command is only enabled by one board, complicates the NAND code,
    and doesn't appear to have been functioning properly for several
    years. If there are no bad blocks in the NAND region being written
    nand_write_skip_bad() will take the shortcut of calling nand_write()
    which bypasses the special yaffs handling. This causes invalid YAFFS
    data to be written. See
    http://lists.denx.de/pipermail/u-boot/2011-September/102830.html for
    an example and a potential workaround.

    U-Boot still retains the ability to mount and access YAFFS partitions
    via CONFIG_YAFFS2.

  • a67cc37e6   dfu, nand: before write a buffer to nand, erase the nand sectors ... Browse Code »

    before writing the received buffer to nand, erase the nand
    sectors. If not doing this, nand write fails. See for
    more info here:

    http://lists.denx.de/pipermail/u-boot/2013-June/156361.html

    Using the nand erase option "spread", maybe overwrite
    blocks on, for example another mtd partition, if the
    erasing range contains bad blocks.
    So a limit option is added to nand_erase_opts()

  • dfe64e2c8   mtd: resync with Linux-3.7.1 ... Browse Code »
    32

    This patch is essentially an update of u-boot MTD subsystem to
    the state of Linux-3.7.1 with exclusion of some bits:

    - the update is concentrated on NAND, no onenand or CFI/NOR/SPI
    flashes interfaces are updated EXCEPT for API changes.

    - new large NAND chips support is there, though some updates
    have got in Linux-3.8.-rc1, (which will follow on top of this patch).

    To produce this update I used tag v3.7.1 of linux-stable repository.

    The update was made using application of relevant patches,
    with changes relevant to U-Boot-only stuff sticked together
    to keep bisectability. Then all changes were grouped together
    to this patch.

  • c39d6a0ea   nand: Extend nand_(read|write)_skip_bad with *actual and limit parameters ... Browse Code »

    We make these two functions take a size_t pointer to how much space
    was used on NAND to read or write the buffer (when reads/writes happen)
    so that bad blocks can be accounted for. We also make them take an
    loff_t limit on how much data can be read or written. This means that
    we can now catch the case of when writing to a partition would exceed
    the partition size due to bad blocks. To do this we also need to make
    check_skip_len count not just complete blocks used but partial ones as
    well. All callers of nand_(read|write)_skip_bad are adjusted to call
    these with the most sensible limits available.

    The changes were started by Pantelis and finished by Tom.

    The implementation is via a new drop_ffs() function which is

    Convert the only flag currently passed to the nand_write_
    skip_bad() function to a bitfield of only one allocated
    member. This should avoid an explosion of int's at the
    end of the parameter list or the ambiguous calls like

    nand_write_skip_bad(info, offset, len, buf, 0, 1, 1);
    nand_write_skip_bad(info, offset, len, buf, 0, 1, 0);

    Instead there will be:

    nand_write_skip_bad(info, offset, len, buf, WITH_YAFFS_OOB |
    WITH_OTHER);

  • 304863225   nand erase: .spread, .part, .chip subcommands ... Browse Code »

    A while back, in http://lists.denx.de/pipermail/u-boot/2009-June/054428.html,
    Michele De Candia posted a patch to not count bad blocks toward the
    requested size to be erased. This is desireable when you're passing in
    something like $filesize, but not when you're trying to erase a partition.

    Thus, a .spread subcommand (named for consistency with
    http://lists.denx.de/pipermail/u-boot/2010-August/075163.html) is introduced
    to make explicit the user's desire to erase for a given amount of data,
    rather than to erase a specific region of the chip.

    While passing $filesize to "nand erase" is useful, accidentally passing
    something like $fliesize currently produces quite unpleasant results, as the
    variable evaluates to nothing and U-Boot assumes that you want to erase
    the entire rest of the chip/partition. To improve the safety of the
    erase command, require the user to make explicit their intentions by
    using a .part or .chip subcommand. This is an incompatible user interface
    change, but keeping compatibility would eliminate the safety gain, and IMHO
    it's worth it.

    While touching nand_erase_opts(), make it accept 64-bit offsets and sizes,
    fix the percentage display when erase length is rounded up, eliminate
    an inconsistent warning about rounding up the erase length which only
    happened when the length was less than one block (rounding up for $filesize
    is normal operation), and add a diagnostic if there's an attempt to erase
    beginning at a non-block boundary.

  • c9f7351b5   NAND: environment offset in OOB (CONFIG_ENV_OFFSET_OOB) ... Browse Code »

    This is a re-submission of the patch by Harald Welte
    with minor modifications for rebase and changes
    as suggested by Scott Wood [1] [2].

    This patch enables the environment partition to have a run-time dynamic
    location (offset) in the NAND flash. The reason for this is simply that
    all NAND flashes have factory-default bad blocks, and a fixed compile
    time offset would mean that sometimes the environment partition would
    live inside factory bad blocks. Since the number of factory default
    blocks can be quite high (easily 1.3MBytes in current standard
    components), it is not economic to keep that many spare blocks inside
    the environment partition.

    With this patch and CONFIG_ENV_OFFSET_OOB enabled, the location of the
    environment partition is stored in the out-of-band (OOB) data of the
    first block in flash. Since the first block is where most systems boot
    from, the vendors guarantee that the first block is not a factory
    default block.

    This patch introduces the 'nand env.oob' command, which can be called
    from the u-boot command line. 'nand env.oob get' reads the address of
    the environment partition from the OOB data, 'nand env.oob set
    {offset,partition-name}' allows the setting of the marker by specifying
    a numeric offset or a partition name.

    Legacy NAND had been scheduled for removal. Any boards that use this
    were already not building in the previous release due to an #error.

    The disk on chip code in common/cmd_doc.c relies on legacy NAND,
    and it has also been removed. There is newer disk on chip code
    in drivers/mtd/nand; someone with access to hardware and sufficient
    time and motivation can try to get that working, but for now disk
