  • 0bd36ee73   MLK-12425-2 video: epdc: introduce epdc support ... Browse Code »

    Support EPDC.
    E-Ink feature is supported by i.MX6DL/SL/SLL/ULL and i.MX7D.

    This driver supports user defined logo file, if there is no logo file, it will
    draw a black border around a white screen.

    If need to enable EPDC, a waveform file is required to let all
    work.

    Since we need LCD_MONOCHROME mode for EPDC, we introduce LCD_MONOCHROME
    support.

    Please refer to Linux Reference Manual for how to flash WAVEFORM file.

  • b7cd95627   fs: add fs_get_type() for current filesystem type ... Browse Code »

    This function is a variant of fs_get_type_name() and returns a filesystem
    type with which the current device is associated.
    We don't want to export fs_type variable directly because we have to take
    care of it consistently within fs.c.

    fs_close() closes the connection to a file system which opened with
    either fs_set_blk_dev() or fs_set_dev_with_part(). Many file system
    functions implicitly call fs_close(), e.g. fs_closedir(), fs_exist(),
    fs_ln(), fs_ls(), fs_mkdir(), fs_read(), fs_size(), fs_write()
    and fs_unlink().
    So just export it.

  • 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.

  • 4bbcc965f   fs: add fs_readdir() ... Browse Code »

    Needed to support efi file protocol. The fallback.efi loader wants
    to be able to read the contents of the /EFI directory to find an OS
    to boot.

    Modelled after POSIX opendir()/readdir()/closedir(). Unlike the other
    fs APIs, this is stateful (ie. state is held in the FS_DIR "directory
    stream"), to avoid re-traversing of the directory structure at each
    step. The directory stream must be released with closedir() when it
    is no longer needed.

    The sandbox/ext4/fat/generic fs commands do not gracefully deal with files
    greater than 2GB. Negative values are returned in such cases.

    To handle this, the fs functions have been modified to take an additional
    parameter of type "* loff_t" which is then populated. The return value
    of the fs functions are used only for error conditions.

  • 59e890ef7   fs: make it possible to read the filesystem UUID ... Browse Code »

    Some filesystems have a UUID stored in its superblock. To
    allow using root=UUID=... for the kernel command line we
    need a way to read-out the filesystem UUID.

    changes rfc -> v1:
    - make the environment variable an option parameter. If not
    given, the UUID is printed out. If given, it is stored in the env
    variable.
    - corrected typos
    - return error codes

    changes v1 -> v2:
    - fix return code of do_fs_uuid(..)
    - document do_fs_uuid(..)
    - implement fs_uuid_unsuported(..) be more consistent with the
    way other optional functionality works

    changes v2 -> v3:
    - change ext4fs_uuid(..) to make use of #if .. #else .. #endif
    construct to get rid of unreachable code

    Hit any key to stop autoboot: 0
    => fsuuid
    fsuuid - Look up a filesystem UUID

    Usage:

    These commands may be used to determine the size of a file without
    actually reading the whole file content into memory. This may be used
    to determine if the file will fit into the memory buffer that will
    contain it. In particular, the DFU code will use it for this purpose
    in the next commit.

  • 6152916a9   fs: implement infrastructure for an 'exists' function ... Browse Code »

    This could be used in scripts such as:

    if test -e mmc 0:1 /boot/boot.scr; then
    load mmc 0:1 ${scriptaddr} /boot/boot.scr
    source ${scriptaddr}
    fi

    rather than:

    if load mmc 0:1 ${scriptaddr} /boot/boot.scr; then
    source ${scriptaddr}
    fi

    This prevents errors being printed by attempts to load non-existent
    files, which can be important when checking for a large set of files,
    such as /boot/boot.scr.uimg, /boot/boot.scr, /boot/extlinux.conf,
    /boot.scr.uimg, /boot.scr, /extlinux.conf.

  • bd6fb31fa   fs: fix generic save command implementation ... Browse Code »

    Fix a few issues with the generic "save" shell command, and fs_write()
    function.

    1) fstypes[].write wasn't filled in for some file-systems, and isn't
    checked when used, which could cause crashes/... if executing save
    on e.g. fat/ext filesystems.

    2) fs_write() requires the length argument to be non-zero, since it needs
    to know exactly how many bytes to write. Adjust the comments and code
    according to this.

    3) fs_write() wasn't prototyped in like other generic functions;
    other code should be able to call this directly rather than invoking
    the "save" shell command.

  • b770e88a6   Fix number base handling of "load" command ... Browse Code »

    As documented, almost all U-Boot commands expect numbers to be entered
    in hexadecimal input format. (Exception: for historical reasons, the
    "sleep" command takes its argument in decimal input format.)

    This rule was broken for the "load" command; for details please see
    especially commits 045fa1e "fs: add filesystem switch libary,
    implement ls and fsload commands" and 3f83c87 "fs: fix number base
    behaviour change in fatload/ext*load". In the result, the load
    command would always require an explicit "0x" prefix for regular
    (i. e. base 16 formatted) input.

    Change this to use the standard notation of base 16 input format.
    While strictly speaking this is a change of the user interface, we
    hope that it will not cause trouble. Stephen Warren comments (see
    [1]):

    I suppose you can change the behaviour if you want; anyone
    writing "0x..." for their values presumably won't be
    affected, and if people really do assume all values in U-Boot
    are in hex, presumably nobody currently relies upon using
    non-prefixed values with the generic load command, since it
    doesn't work like that right now.

  • f9b55e228   fs: rename fsload command to load ... Browse Code »

    When the generic filesystem load command "fsload" was written, I felt
    that "load" was too generic of a name for it, since many other similar
    commands already existed. However, it turns out that there is already
    an "fsload" command, so that name cannot be used. Rename the new
    "fsload" to plain "load" to avoid the conflict. At least anyone who's
    used a Basic interpreter should feel familiar with the name!

  • 3f83c87ee   fs: fix number base behaviour change in fatload/ext*load ... Browse Code »

    Commit 045fa1e "fs: add filesystem switch libary, implement ls and
    fsload commands" unified the implementation of fatload and ext*load
    with the new command fsload. However, this altered the interpretation
    of command-line numbers from always being base-16, to requiring a "0x"
    prefix for base-16 numbers. Enhance do_fsload() to allow commands to
    specify which base to use.

    Use base 0, thus requiring a "0x" prefix for the new fsload command.
    This feels much cleaner than assuming base 16.

    Use base 16 for the pre-existing fatload and ext*load to prevent a
    change in behaviour.

    Use base 16 exclusively for the loadaddr environment variable, since
    that variable is interpreted in multiple places, so we don't want the
    behaviour to change.

    Update command help text to make it clear where numbers are assumed to
    be hex, and where an explicit "0x" prefix is required.

    Implement "ls" and "fsload" commands that act like {fat,ext2}{ls,load},
    and transparently handle either file-system. This scheme could easily be
    extended to other filesystem types; I only didn't do it for zfs because
    I don't have any filesystems of that type to test with.

    Replace the implementation of {fat,ext[24]}{ls,load} with this new code
    too.
