  • 203f9b48a   GPT: provide commands to selectively rename partitions ... Browse Code »

    This patch provides support in u-boot for renaming GPT
    partitions. The renaming is accomplished via new 'gpt swap'
    and 'gpt rename' commands.

    The 'swap' mode returns an error if no matching partition names
    are found, or if the number of partitions with one name does not equal
    the number with the second name. The 'rename' variant always
    succeeds as long as a partition with the provided number exists.

    Rewriting the partition table has the side-effect that all partitions
    end up with "msftdata" flag set. The reason is that partition type
    PARTITION_BASIC_DATA_GUID is hard-coded in the gpt_fill_pte()
    function. This does not appear to cause any harm.

  • 73d6d18b7   GPT: add accessor function for disk GUID ... Browse Code »
    24

    In order to read the GPT, modify the partition name strings, and then
    write out a new GPT, the disk GUID is needed. While there is an
    existing accessor for the partition UUIDs, there is none yet for the
    disk GUID.

    Changes since v6: none.

  • 0a2423862   GPT: fix error in partitions string doc ... Browse Code »

    The existing partitions-list parsing in cmd/gpt.c passes a value
    from gpt_default() to set_gpt_info() that README.gpt suggests
    should begin with 'partitions='. Partition-list strings should
    in fact begin with 'uuid_disk', as otherwise the call from
    set_gpt_info() to extract_val() to find 'uuid_disk' will fail.
    Change README.gpt accordingly.

    Changes since v6: none.

  • cfdaf4caa   part:efi: add bootable parameter in gpt command ... Browse Code »

    The optional parameter bootable is added in gpt command to set the
    partition attribute flag "Legacy BIOS bootable"

    This flag is used in extlinux and so in with distro to select
    the boot partition where is located the configuration file
    (please check out doc/README.distro for details).

    With this parameter, U-Boot can be used to create the boot partition
    needed for device using distro.

    example of use:

    setenv partitions "name=u-boot,size=60MiB;name=boot,size=60Mib,bootable;\
    name=rootfs,size=0"

    > gpt write mmc 0 $partitions

    > part list mmc 0

    Partition Map for MMC device 0 -- Partition Type: EFI

    Part Start LBA End LBA Name
    Attributes
    Type GUID
    Partition GUID
    1 0x00000022 0x0001e021 "u-boot"
    attrs: 0x0000000000000000
    type: ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
    guid: cceb0b18-39cb-d547-9db7-03b405fa77d4
    2 0x0001e022 0x0003c021 "boot"
    attrs: 0x0000000000000004
    type: ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
    guid: d4981a2b-0478-544e-9607-7fd3c651068d
    3 0x0003c022 0x003a9fde "rootfs"
    attrs: 0x0000000000000000
    type: ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
    guid: 6d6c9a36-e919-264d-a9ee-bd00379686c7

    > part list mmc 0 -bootable devplist

    > printenv devplist

    devplist=2

    Then the distro scripts will search extlinux in partition 2
    and not in the first partition.

  • b38c108a9   part:efi: add GUID for linux file system data ... Browse Code »

    Previously, Linux used the same GUID for the data partitions as Windows
    (Basic data partition: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7).
    This created problems when dual-booting Linux and Windows in UEFI-GPT
    Setup, so a new GUID (Linux filesystem data:
    0FC63DAF-8483-4772-8E79-3D69D8477DE4) was defined jointly by GPT fdisk
    and GNU Parted developers.
