    With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type,
    which is required to represent block numbers for storage devices that
    exceed 2TiB (the block size usually is 512B), e.g. recent hard drives

    We now use lbaint_t for partition offset to reflect the lbaint_t change,
    and access partitions beyond or crossing the 2.1TiB limit.
    This required changes to signature of ext4fs_devread(), and type of all
    variables relatives to block sector.

    ext2/ext4 fs uses logical block represented by a 32 bit value. Logical
    block is a multiple of device block sector. To avoid overflow problem
    when calling ext4fs_devread(), we need to cast the sector parameter.

  • 10a37fd7a   disk: get_device_and_partition() "auto" partition and cleanup ... Browse Code »
    46

    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.

    [swarren: Rob implemented scanning for bootable partitions. I fixed a
    couple of issues there, switched the syntax to ":auto", added the
    error-checking rework, and ":0" syntax for the whole device]

    All the raw block load commands duplicate the same code. Starting with
    the ide version as it has progress updates convert ide, usb, and scsi boot
    commands to all use a common version.
