  • The way that struct mmc was implemented was a bit of a mess;
    configuration and internal state all jumbled up in a single structure.

    On top of that the way initialization is done with mmc_register leads
    to a lot of duplicated code in drivers.

    Typically the initialization got something like this in every driver.

    struct mmc *mmc = malloc(sizeof(struct mmc));
    memset(mmc, 0, sizeof(struct mmc);
    /* fill in fields of mmc struct */
    /* store private data pointer */
    mmc_register(mmc);

    By using the new mmc_create call one just passes an mmc config struct
    and an optional private data pointer like this:

    struct mmc = mmc_create(&cfg, priv);

    All in tree drivers have been updated to the new form, and expect
    mmc_register to go away before long.

    Changes since v1:

    * Use calloc instead of manually calling memset.
    * Mark mmc_register as deprecated.

  • Add a simple LCD driver which uses SDL to display the image. We update the

    Adjust the common lcd code to support sandbox.

    For command-line runs we do not want the LCD to be displayed, so add a

  • At present we use U-Boot's filesystem layer to read the sandbox device tree,
    but this is problematic since it relies on a temporary feauture added
    there. Since we plan to implement proper block layer support for sandbox,
    change this code to use the os layer functions instead. Also use the new
    fdt_create_empty_tree() instead of our own code.

  • Before this commit, CONFIG_MPC8260 and CONFIG_8260
    were used mixed-up.

    All boards with mpc8260 cpu defined both of them:
    - CONFIG_MPC8260 was defined in board config headers
    and include/common.h
    - CONFIG_8260 was defined arch/powerpc/cpu/mpc8260/config.mk

    We do not need to have both of them.
    This commit keeps only CONFIG_MPC8260.

    This commit does:
    - Delete CONFIG_8260 and CONFIG_MPC8260 definition
    in config headers and include/common.h
    - Rename CONFIG_8260 to CONFIG_MPC8260
    in arch/powerpc/cpu/mpc8260/config.mk.
    - Rename #ifdef CONFIG_8260 to #ifdef CONFIG_MPC8260

  • The following shell command fails:

    if test -z "$x"; then echo "zero"; else echo "non-zero"; fi

    (assuming $x does not exist, it prints "non-zero" rather than "zero").

    ... since "$x" expands to nothing, and the argument is completely
    dropped, causing too few to be passed to -z, causing cmd_test() to
    error out early.

    This is because when variable expansions are processed by make_string(),
    the expanded results are concatenated back into a new string. However,
    no quoting is applied when doing so, so any empty variables simply don't
    generate any parameter when the combined string is parsed again.

    Fix this by explicitly replacing quoting any argument that was originally
    quoted when re-generating a string from the already-parsed argument list.

    This also fixes loss of whitespace in commands such as:

    setenv space " "
    setenv var " 1${space}${space} 2 "
    echo ">>${var}<

  • U-Boot now uses errors defined in include/errno.h which are negative
    integers. Commands which fail need to report the error and return 1
    to indicate failure. Add this functionality in cmd_process_error().

    For now this merely reports the error number. It would be possible
    also to produce a helpful error message by storing the error strings
    in U-Boot.

  • 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.

  • do_bootm_standanlone() calls ntohl(images->ep) which is wrong because
    endianess conversion has already been done:

    do_bootm()
    \-do_bootm_states()
    +-bootm_find_os()
    | \-images.ep = image_get_ep();
    | \-uimage_to_cpu(hdr->ih_ep);
    \-boot_selected_os()
    \-do_bootm_standanlone()

    Without this conversion the code works correctly at least on AT91SAM9G45.
    On big endian systems there should be no difference after applying this
    patch because uimage_to_cpu(x) and ntohl(x) both expand to 'x'.

  • 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.
