  • 1fddd7b63   tools/imagetool: remove linker script ... Browse Code »

    Commit a93648d197df48fa46dd55f925ff70468bd81c71 introduced linker generated
    lists for imagetool which is the base for some host tools (mkimage, dumpimage,
    et al.). Unfortunately some host tool chains do not support the used type of
    linker scripts. Therefore this commit broke these host-tools for them, namely
    FreeBSD and Darwin (OS/X).

    This commit tries to fix this. In order to have a clean distinction between host
    and embedded code space we need to introduce our own linker generated list
    instead of re-using the available linker_lists.h provided functionality. So we
    copy the implementation used in linux kernel script/mod/file2alias.c which has
    the very same problem (cause it is a host tool). This code also comes with an
    abstraction for Mach-O binary format used in Darwin systems.

  • 832472a94   tools: socfpga: Add socfpga preloader signing to mkimage ... Browse Code »
    43

    Like many platforms, the Altera socfpga platform requires that the
    preloader be "signed" in a certain way or the built-in boot ROM will
    not boot the code.

    This change automatically creates an appropriately signed preloader
    from an SPL image.

    The signed image includes a CRC which must, of course, be generated
    with a CRC generator that the SoCFPGA boot ROM agrees with otherwise
    the boot ROM will reject the image.

    Unfortunately the CRC used in this boot ROM is not the same as the
    Adler CRC in lib/crc32.c. Indeed the Adler code is not technically a
    CRC but is more correctly described as a checksum.

    Thus, the appropriate CRC generator is added to lib/ as crc32_alt.c.

    V2: - Zap unused constant
    - Explicitly print an error message in case of error
    - Rework the hdr_checksum() function to take the *header directly
    instead of a plan buffer pointer

  • 7b1a41174   mkimage: add atmelimage ... Browse Code »

    The new atmelimage converts a machine code BLOB to bootable ROM image. Atmel
    ROM has no sophisticated image format, it only checks the first 7 ARM vectors.
    The vectors can contain valid B or LDR opcodes, the 6'th vector contains the
    image size to load.

    Additionally the PMECC header can be written by the atmelimage target. The
    parameters must be given via the -n switch as a coma separated list. For
    example:

    mkimage -T atmelimage \
    -n usePmecc=1,sectorPerPage=4,sectorSize=512,spareSize=64,eccBits=4,eccOffset=36 \
    -d spl/u-boot-spl.bin boot.bin

    A provided image can be checked for correct header setup. It prints out the
    PMECC header parameters if it has one and the 6'th interrupt vector content.

    ---88---

    A SPL binary modified with the atmelimage mkimage target was succesfully
    booted on a sama5d34ek via MMC and NAND.

  • f86ed6a8d   tools: moved code common to all image tools to a separated module. ... Browse Code »
    43

    In order to avoid duplicating code and keep only one point of modification,
    the functions, structs and defines useful for "dumpimage" were moved from
    "mkimage" to a common module called "imagetool".

    This modification also weakens the coupling between image types (FIT, IMX, MXS,
    and so on) and image tools (mkimage and dumpimage). Any tool may initialize the
    "imagetool" through register_image_tool() function, while the image types
    register themselves within an image tool using the register_image_type()
    function:

    +---------------+
    +------| fit_image |
    +--------------+ +-----------+ | +---------------+
    | mkimage |--------> | | | |
