  • U-Boot has imported various source files from other projects,
    mostly Linux.

    Something like

    #ifdef __UBOOT__
    [ modification for U-Boot ]
    #else
    [ original code ]
    #endif

    is an often used strategy for clarification of adjusted parts,
    that is, easier re-sync in future.

    Instead of defining __UBOOT__ in each source file,
    passing it from the top Makefile would be easier.

  • 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.

  • ext4fs_allocate_blocks() always allocates at least one block for a file.
    If the file size is zero, this causes total_remaining_blocks to
    underflow, which then causes an apparent hang while 2^32 blocks are
    allocated.

    To solve this, check that total_remaining_blocks is non-zero as part of
    the loop condition (i.e. before each loop) rather than at the end of
    the loop.

  • When write a file into FAT file system, it will search a match file in
    root dir. So the find_directory_entry() will get the first cluster of
    root dir content and search the directory item one by one. If the file
    is not found, we will call get_fatent_value() to get next cluster of root
    dir via lookup the FAT table and continue the search.

    The issue is in FAT16/12 system, we cannot get root dir's next clust
    from FAT table. The FAT table only be use to find the clust of data
    aera in FAT16/12.

    In FAT16/12 if the clust is in root dir, the clust number is a negative
    number or 0, 1. Since root dir is located in front of the data area.
    Data area start clust #2. So the root dir clust number should < 2.

    This patch will check above situation before call get_fatenv_value().
    If curclust is < 2, include minus number, we just increase one on the
    curclust since root dir is in continous cluster.

    The patch also add a sanity check for entry in get_fatenv_value().

  • In fat_write.c, the last clust condition check is incorrect:

    if ((curclust >= 0xffffff8) || (curclust >= 0xfff8)) {
    ... ...
    }

    For example, in FAT32 if curclust is 0x11000. It is a valid clust.
    But on above condition check, it will be think as a last clust.

    So the correct last clust check should be:
    in fat32, curclust >= 0xffffff8
    in fat16, curclust >= 0xfff8
    in fat12, curclust >= 0xff8

    This patch correct the last clust check.

  • This bug shows up when file stored on the ext4 file system is updated.

    The ext4fs_delete_file() is responsible for deleting file's (e.g. uImage)
    data.
    However some global data (especially ext4fs_indir2_block), which is used
    during file deletion are left unchanged.

    The ext4fs_indir2_block pointer stores reference to old ext4 double
    indirect allocated blocks. When it is unchanged, after file deletion,
    ext4fs_write_file() uses the same pointer (since it is already initialized
    - i.e. not NULL) to return number of blocks to write. This trunks larger
    file when previous one was smaller.

    Lets consider following scenario:

    1. Flash target with ext4 formatted boot.img (which has uImage [*] on itself)
    2. Developer wants to upload their custom uImage [**]
    - When new uImage [**] is smaller than the [*] - everything works
    correctly - we are able to store the whole smaller file with corrupted
    ext4fs_indir2_block pointer
    - When new uImage [**] is larger than the [*] - theCRC is corrupted,
    since truncation on data stored at eMMC was done.
    3. When uImage CRC error appears, then reboot and LTHOR/DFU reflashing causes
    proper setting of ext4fs_indir2_block() and after that uImage[**]
    is successfully stored (correct uImage [*] metadata is stored at an
    eMMC on the first flashing).

    Due to above the bug was very difficult to reproduce.
    This patch sets default values for all ext4fs_indir* pointers/variables.

  • When we tell the compiler to optimize for ARMv7 (and ARMv6 for that
    matter) it assumes a default of SCTRL.A being cleared and unaligned
    accesses being allowed and fast at the hardware level. We set this bit
    and must pass along -mno-unaligned-access so that the compiler will
    still breakdown accesses and not trigger a data abort.

    To better help understand the requirements of the project with respect
    to unaligned memory access, the
    Documentation/unaligned-memory-access.txt file has been added as
    doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1
    tag of the kernel.

  • In an ext4 filesystem, the inode corresponding to a file has a 60-byte
    area which contains an extent header structure and up to 4 extent
    structures (5 x 12 bytes).

    For files that need more than 4 extents to be represented (either files
    larger than 4 x 128MB = 512MB or smaller files but very fragmented),
    ext4 creates extent index structures. Each extent index points to a 4KB
    physical block where one extent header and additional 340 extents could
    be stored.

    The current u-boot ext4 code is very inefficient when it tries to load a
    file which has extent indexes. For each logical file block the code will
    read over and over again the same blocks of 4096 bytes from the disk.

    Since the extent tree in a file is always the same, we can cache the
    extent structures in memory before actually starting to read the file.

    This patch creates a simple linked list of structures holding information
    about all the extents used to represent a file. The list is sorted by
    the logical block number (ee_block) so that we can easily find the
    proper extent information for any file block.

    Without this patch, a 69MB file which had just one extent index pointing
    to a block with another 6 extents was read in approximately 3 minutes.
    With this patch applied the same file can be read in almost 20 seconds.

  • Now we are ready to switch over to real Kbuild.

    This commit disables temporary scripts:
    scripts/{Makefile.build.tmp, Makefile.host.tmp}
    and enables real Kbuild scripts:
    scripts/{Makefile.build,Makefile.host,Makefile.lib}.

    This switch is triggered by the line in scripts/Kbuild.include
    -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
    +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj

    We need to adjust some build scripts for U-Boot.
    But smaller amount of modification is preferable.

    Additionally, we need to fix compiler flags which are
    locally added or removed.

    In Kbuild, it is not allowed to change CFLAGS locally.
    Instead, ccflags-y, asflags-y, cppflags-y,
    CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
    are prepared for that purpose.

  • This commit changes the working directory
    where the build process occurs.

    Before this commit, build process occurred under the source
    tree for both in-tree and out-of-tree build.

    That's why we needed to add $(obj) prefix to all generated
    files in makefiles like follows:
    $(obj)u-boot.bin: $(obj)u-boot

    Here, $(obj) is empty for in-tree build, whereas it points
    to the output directory for out-of-tree build.

    And our old build system changes the current working directory
    with "make -C " syntax when descending into the
    sub-directories.

    On the other hand, Kbuild uses a different idea
    to handle out-of-tree build and directory descending.

    The build process of Kbuild always occurs under the output tree.
    When "O=dir/to/store/output/files" is given, the build system
    changes the current working directory to that directory and
    restarts the make.

    Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj="
    syntax for descending into sub-directories.
    (We can write it like "make $(obj)=" with a shorthand.)
    This means the current working directory is always the top
    of the output directory.

  • This could be used in scripts such as:

    load mmc 0:1 ${scriptaddr} /boot/boot.scr

    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,

  • 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.

  • For files where we actually have extent indexes following
    an extent header (ext_block->eh_depth != 0), the do/while
    loop from ext4fs_get_extent_block() does not select the
    proper extent index structure.

    For example, if we have:

    ext_block->eh_depth = 1
    ext_block->eh_entries = 1
    fileblock = 0
    index[0].ei_block = 0

    the do/while loop will exit with i set to 0 and the
    ext4fs_get_extent_block() function will return 0, even if
    there was a valid extent index structure following the
