  • f4d8de48f   sandbox: block driver using host file/device as backing store ... Browse Code »

    Provide a way to use any host file or device as a block device in U-Boot.
    This can be used to provide filesystem access within U-Boot to an ext2
    image file on the host, for example.

    The support is plumbed into the filesystem and partition interfaces.

    We don't want to print a message in the driver every time we find a missing
    device. Pass the information back to the caller where a message can be printed
    if desired.

  • 50ffc3b64   fs/ext4: fix log2blksz un-initialized error, by cacaulating its value from blksz ... Browse Code »

    The problem here is that uboot can't mount ext4 filesystem with
    commit "50ce4c07df1" applied. We use hard-coded "SECTOR_SIZE"(512)
    before this commit, now we introduce (block_dev_desc_t *)->log2blksz
    to replace this macro. And after we calling do_ls()->fs_set_blk_dev(),
    the variable log2blksz is not initialized, which it's not correct.

    And this patch try to solve the problem by caculating the value of
    log2blksz from variable blksz.

  • 33699df12   part: check each variable for capability calculation ... Browse Code »

    In order to calculate the capability, we use the below expression to check:
    ((dev_desc->lba * dev_desc->blksz)>0L)
    If the capability is greater than 4GB (e.g. 8GB = 8 * 1024 * 104 * 1024),
    the result will overflow, the low 32bit may be zero.

    Therefore, change to check each variable to fix this potential issue.

  • 0c9c8fb5e   disk: Make the disk partition code work with no specific partition types ... Browse Code »

    Currently, if the disk partition code is compiled with all of the parition
    types compiled out, it hits an #error which stops the build. This change
    adjusts that file so that those functions will fall through to their defaults
    in those cases instead of breaking the build. These functions are needed
    because other code calls them, and that code is needed because other config
    options are overly broad and bring in support we don't need along with
    support we do.

    Also reduce repetition of the 6-term #ifdef throughout the file.

  • 6ab6a650a   disk: initialize name/part fields when returning a whole disk ... Browse Code »

    When get_device_and_partition() finds a disk without a partition table,
    under some conditions, it "returns" a disk_partition_t that describes
    the entire raw disk. Make sure to initialize all fields in the partition
    descriptor in that case.

    The value chosen for name is just some arbitrary descriptive string.

    The value chosen for info matches the check at the end of
    get_device_and_partition(). However, it's probably not that important;
    it's not obvious that the value is really used.

  • 71bba424a   disk: get_device_and_partition() return value fixes ... Browse Code »

    When no valid partitions are found, guarantee that we return -1. This
    most likely already happens, since the most recent get_partition_info()
    will have returned an error. However, it's best to be explicit.

    Remove an unnecessary assignment of ret=0 in the success case; this value
    is over-written with the processed partition ID later.

    Rework get_device_and_partition() to:
    a) Implement a new partition ID of "auto", which requests that U-Boot
    search for the first "bootable" partition, and fall back to the first
    valid partition if none is found. This way, users don't need to
    specify an explicit partition in their commands.
    b) Make use of get_device().
    c) Add parameter to indicate whether returning a whole device is
    acceptable, or whether a partition is mandatory.
    d) Make error-checking of the user's device-/partition-specification
    more complete. In particular, if strtoul() doesn't convert all
    characters, it's an error rather than just ignored.

    The resultant device/partition returned by the function will be as
    follows, based on whether the disk has a partition table (ptable) or not,
    and whether the calling command allows the whole device to be returned
    or not.

    (D and P are integers, P >= 1)

    D
    D:
    No ptable:
    !allow_whole_dev: error
    allow_whole_dev: device D
    ptable:
    device D partition 1
    D:0
    !allow_whole_dev: error
    allow_whole_dev: device D
    D:P
    No ptable: error
    ptable: device D partition P
    D:auto
    No ptable:
    !allow_whole_dev: error
    allow_whole_dev: device D
    ptable:
    first partition in device D with bootable flag set.
    If none, first valid paratition in device D.

    Note: In order to review this patch, it's probably easiest to simply
    look at the file contents post-application, rather than reading the
    patch itself.

  • 2023e6086   disk: introduce get_device() ... Browse Code »

    This patch introduces function get_device(). This looks up a
    block_dev_desc_t from an interface name (e.g. mmc) and device number
    (e.g. 0). This function is essentially the non-partition-specific
    prefix of get_device_and_partition().

    All block device related commands (scsiboot, fatload, ext2ls, etc.) have
    simliar duplicated device and partition parsing and selection code. This
    adds a common function to replace various implementations.

    The new function has an enhancement over current versions. If no device
    or partition is specified on the command line, the bootdevice env variable
    will be used (scsiboot does this).

  • 2f5016462   disk: make get_partition_info() always available to disk.c ... Browse Code »

    Now that get_device_and_partition() always calls get_partition_info()
    when disk.c is compiled, we must always compile the function, rather
    than ifdef it away.

    The implementation must be conditional based on CONFIG_CMD_* etc., since
    that's what e.g. part_dos.c uses to ifdef out get_partition_info_dos();
    CONFIG_DOS_PARTITION can be enabled even without those commands being
    enabled.

    Technically, this change is required before Rob's "disk/part: introduce
    get_device_and_partition" patch. However, at least when the compiler
    optimizer is turned on, it isn't required before then in practice,
    since get_device_and_partition() calls get_dev(), which is stubbed out
    in disk.c under exactly the same conditions that get_partition_info()
    is not compiled, and hence the compiler never generates code for the
    call to the missing function. However, in my later patch "disk:
    get_device_and_partition() "auto" partition and cleanup", the optimizer
    doesn't succeed at this, and may attempt to reference the undefined
    function.

  • 7e71dc688   disk/part.c: Fix device enumeration through API ... Browse Code »

    The patch below fixes device enumeration through the U-Boot API.

    Device enumeration crashes when the system in question doesn't
    have any RAM mapped to address zero (I discovered this on a
    BeagleBone board), since the enumeration calls get_dev with a
    NULL ifname sometimes which then gets passed down to strncmp().

    This fix simply ensures that get_dev returns NULL when invoked
    with a NULL ifname.

  • af75a45d2   IDE: bail out of dev_print() for unknown device types ... Browse Code »

    Commit 574b319512 introduced a subtle bug by mixing a list of tests
    for "dev_desc->type" and "dev_desc->if_type" into one switch(), which
    then mostly did not work because "dev_desc->type" cannot take any
    "IF_*" type values. A later fix in commit 8ec6e332ea changed the
    switch() into testing "dev_desc->if_type", but at this point the
    initial test for unknown device types was completely lost, which
    resulted in output like that for IDE ports without device attached:

    Device 1: Model: Firm: Ser#:
    Type: # 1F #
    Capacity: not available

    This patch re-introduces the missing test for unknown device types.

    some different operation (ATA, IO, XIP) modes.

    IO mode is custom mode for the host that doesn't have IDE interface.
    (Many mobile targeted SoC doesn't have IDE bus)

    This driver support mflash IO mode.

    Followings are brief descriptions about IO mode.

    1. IO mode based on ATA protocol and uses some custom command. (read
    confirm, write confirm)
    2. IO mode uses SRAM bus interface.

    This brings in support for the %p modifier which allows us to easily print

    It also converts the rarely used 'q' length modifier to the common 'L'

    While this new code is a bit larger (~1k .text), most of it should be made
    up by converting the existing ip/mac address code to use format modifiers.
