  • 336d4615f   dm: core: Create a new header file for 'compat' features ... Browse Code »
    1

    At present dm/device.h includes the linux-compatible features. This
    requires including linux/compat.h which in turn includes a lot of headers.
    One of these is malloc.h which we thus end up including in every file in
    U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
    which needs to use the system malloc() in some files.

    Move the compatibility features into a separate header file.

    1

    At present devres.h is included in all files that include dm.h but few
    make use of it. Also this pulls in linux/compat which adds several more
    headers. Drop the automatic inclusion and require files to include devres
    themselves. This provides a good indication of which files use devres.

  • e6661cf76   ubi: Add "skipcheck" command to set/clear this bit in the UBI volume hdr ... Browse Code »

    U-Boot now supports the "skip_check" flag to optionally skip the CRC
    check at open time. Currently its only possible to set this bit upon
    UBI volume creation. But it might be very useful to also set this bit
    on already installed systems (e.g. field upgrade) to make also use of
    the boot-time decrease on those systems.

    This patch now adds a new "ubi" command "ubi skipcheck" to set or clear
    this bit in the UBI volume header:

    => ubi skipcheck rootfs0 on
    Setting skip_check on volume rootfs0

    BTW: This saves approx. 10 seconds Linux bootup time on a MT7688 based
    target with 128MiB of SPI NAND.

  • 386f20cad   ubi: provide a way to skip CRC checks ... Browse Code »

    Some users of static UBI volumes implement their own integrity check,
    thus making the volume CRC check done at open time useless. For
    instance, this is the case when one use the ubiblock + dm-verity +
    squashfs combination, where dm-verity already checks integrity of the
    block device but this time at the block granularity instead of verifying
    the whole volume.

    Skipping this test drastically improves the boot-time.

    Adapted to U-Boot by Stefan Roese.

  • 86dfa556d   cmd: ubi: Remove useless call to mtdparts_init() ... Browse Code »
    14

    Commit c58fb2cdb3e4 ("cmd: ubi: clean the partition handling")
    introduced a call to mtd_probe_devices() in the ubi_attach() path
    and this function takes care of parsing mtdparts/mtdids and
    creating/registering the associated mtd partitions.

    The mtdparts_init() call in the ubi_detach() path is not only
    unnecessary but can sometimes print error messages even when things
    work properly (that's the case with SPI NAND devices that have not
    been probed with 'mtd list'), which is misleading.

    Remove this call to mtdparts_init() and drop the dependency on
    CMD_MTDPARTS.

    cmd_ubifs_umount() function would be called directly instead of involving
    whole command machinery in generic firmware loader, so checking on
    ubifs_initialized status need to be done in cmd_ubifs_umount() without
    breaking original functionality design.

    These definitions are simply not used and are misleading because similar
    definitions exist in jffs2/load_kernel.h and are used widely to define
    MTD device types (which is, by the way, totally redundant with what the
    MTD core does). Remove these definitions.

  • 4a94e53b2   cmd: ubi: Add additional message upon UBI attach error ... Browse Code »

    When trying to attach an UBI MTD partition via "ubi part", it may happen
    that the MTD partition defined in U-Boot (via mtdparts) is not big
    enough than the one, where the UBI device has been created on. This
    may lead to errors, which are not really descriptive to debug and
    solve this issue, like:

    ubi0 error: vtbl_check: too large reserved_pebs 1982, good PEBs 1020
    ubi0 error: vtbl_check: volume table check failed: record 0, error 9

    or:

    ubi0 error: init_volumes: not enough PEBs, required 1738, available 1020
    ubi0 error: ubi_wl_init: no enough physical eraseblocks (-718, need 1)
    ubi0 error: ubi_attach_mtd_dev: failed to attach mtd1, error -12

    Lets add an additional message upon attach failure, to aid the U-Boot
    user to solve this problem.

  • 68c7025d9   cmd: ubi: print load size after establishing volume size ... Browse Code »
    14

    When using static volumes, the file size stored in the volume is
    determined at runtime. Currently the ubi command prints the file
    size specified on the console, which leads to a rather confusing
    series of messages:
    # ubi read ${fdt_addr_r} testvol
    Read 0 bytes from volume testvol to 82000000
    No size specified -> Using max size (179924992)

    Make sure to print the actual size read in any case:
    # ubi read ${fdt_addr_r} testvol
    No size specified -> Using max size (179924992)
    Read 179924992 bytes from volume testvol to 82000000

  • 985fa93e6   cmd: set filesize variable in ubi read ... Browse Code »

    After a successful read of a UBI volume, the variable filesize is set
    to the number of read bytes. To boot linux with a raw initramfs/initrd,
    you must specify the exact size of the initramfs/initrd image in boot
    command. If the initramfs/inird is read from UBI volume, $filesize is
    required to access the number of read bytes.

    Example:
    ubi read ${loadaddr} kernelvol
    ubi read ${fdtaddr} dtbvol
    ubi read ${initrd_addr} initrdvol
    bootz ${loadaddr} ${initrd_addr}:${filesize} ${fdt_addr}
