  • d57d60cf2   kbuild: move "checkgcc4" to PowerPC archprepare ... Browse Code »

    "checkgcc4" is used only for PowerPC.
    Move it to arch/powerpc/config.mk.

    To make sure gcc is new enough before beginning build,
    run "checkgcc4" during "archprepare".

    "checkthumb" makes sense only for ARM architecture.
    Move it to arch/arm/config.mk.

    To make sure gcc supports THUMB mode before beginning build,
    run "checkthumb" during "archprepare".

  • 026f9cf24   kbuild: improve Kbuild speed ... Browse Code »

    Kbuild brought about many advantages for us but a significant
    performance regression was reported by Simon Glass.

    After some discussions and analysis, it turned out
    its main cause is in $(call cc-option,...).

    Historically, U-Boot parses all config.mk
    (arch/*/config.mk and board/*/config.mk)
    every time descending into subdirectories.
    That means cc-options are evaluated over and over again.

    $(call cc-option,...) is useful but costly.
    So we want to evaluate them only in ./Makefile
    and spl/Makefile and export compiler flags.

    This commit changes the build system as follows:

    - Modify scripts/Makefile.build to not include config.mk
    Instead, add $(PLATFORM_CPPFLAGS) to asflags-y, ccflags-y,
    cppflags-y.

    - Export many variables
    Going forward, Kbuild will not parse config.mk files
    when it descends into subdirectories.
    If we want to set variables in config.mk and use them
    in subdirectories, they must be exported.

    This is the list of variables to get exported:
    PLATFORM_CPPFLAGS
    CPUDIR
    BOARDDIR
    OBJCOPYFLAGS
    LDFLAGS
    LDFLAGS_FINAL
    (used in nand_spl/board/*/*/Makefile)
    CONFIG_STANDALONE_LOAD_ADDR
    (used in examples/standalone/Makefile)
    SYM_PREFIX
    (used in examples/standalone/Makefile)
    RELFLAGS
    (used in examples/standalone/Makefile)

    - Delete CPPFLAGS
    This variable has been replaced with PLATFORM_CPPFLAGS

    - Copy gcclibdir from example/standalone/Makefile
    to arch/sparc/config.mk
    The reference in CONFIG_STANDALONE_LOAD_ADDR must be
    resolved before it is exported.

  • cd2e46cb3   kbuild: add CONFIG_ prefix to USE_PRIVATE_LIBGCC ... Browse Code »

    Before this commit, USE_PRIVATE_LIBGCC was defined in
    arch-specific config.mk and referenced in
    arch/$(ARCH)/lib/Makefile.

    We are not happy about parsing config.mk again and again.
    We have to keep the same behavior with a different way.

    By adding "CONFIG_" prefix, this macro appears
    in include/autoconf.mk, include/spl-autoconf.mk.
    (And treating USE_PRIVATE_LIBGCC as CONFIG macro
    is reasonable enough.)

    Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes"
    in arch/arm/cpu/arm720t/tegra*/config.mk,
    whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk.

    It means Tegra enables PRIVATE_LIBGCC only for SPL.
    We can describe the same behavior by adding

    #ifdef CONFIG_SPL_BUILD
    # define CONFIG_USE_PRIVATE_LIBGCC
    #endif

    to include/configs/tegra-common.h.

  • 33a02da0f   kbuild: allow empty board directories ... Browse Code »
    92

    U-Boot has compelled all boards to have
    board/${BOARD}/ or board/${VENDOR}/${BOARD}/ directory.

    Sometimes it does not seem suitable for some boards,
    for example Sandbox. (Is it a board?)

    And arcangel4 board has nothing to compile
    under the board directory.

    This commit makes the build system more flexible:
    If '' is given to the 6th column (=Board name) of boards.cfg,
    Kbuild will not descend into the board directory.

  • db5b339cc   kbuild: add "cross_tools" target to build tools for the target ... Browse Code »

    Programs in tools/ directory are usually built for the host.
    But some of them (mkimage, dumpimge, gen_eth_addr, etc.) are
    useful on the target OS too.

    Actually, prior to Kbuild, U-Boot could build tools for
    the target like follows:

    $ make _config
    $ export CROSS_COMPILE=
    $ make HOSTCC=${CROSS_COMPILE}gcc HOSTSTRIP=${CROSS_COMPILE}strip tools

    In Kbuild, we can no longer replace HOSTCC at the command line.

    In order to get back that feature, this commit adds "cross-tools" target.

    Usage:

    Build tools for the host
    $ make CROSS_COMPILE= tools

    Build tools for the target
    $ make CROSS_COMPILE= cross_tools

    Besides, "make cross_tools" strip tools programs because we
    generally expect smaller storages on embedded systems.

  • 39f7611fe   dm: Add a demonstration/example driver ... Browse Code »

    As an example of how to write a uclass and a driver, provide a demo version
    of each, accessible through the 'demo' command.

    To use these with driver model, define CONFIG_CMD_DEMO and CONFIG_DM_DEMO.

    The two demo drivers are enabled with CONFIG_DM_DEMO_SIMPLE and
    CONFIG_DM_DEMO_SHAPE.

  • 2e7d35d2a   dm: Add basic tests ... Browse Code »

    Add some tests of driver model functionality. Coverage includes:

    - basic init
    - binding of drivers to devices using platform_data
    - automatic probing of devices when referenced
    - availability of platform data to devices
    - lifecycle from bind to probe to remove to unbind
    - renumbering within a uclass when devices are probed/removed
    - calling driver-defined operations
    - deactivation of drivers when removed
    - memory leak across creation and destruction of drivers/uclasses
    - uclass init/destroy methods
    - automatic probe/remove of children/parents when needed

    This function is enabled for sandbox, using CONFIG_DM_TEST.

    Add driver model functionality for generic board.

    This includes data structures and base code for registering devices and
    uclasses (groups of devices with the same purpose, e.g. all I2C ports will
    be in the same uclass).

    The feature is enabled with CONFIG_DM.

    Add support for building a device tree for sandbox's CONFIG_OF_HOSTFILE
    option to make it easier to use device tree with sandbox.

    This adjusts the Makefile to build a u-boot.dtb file which can be passed
    to sandbox U-Boot with:

    ./u-boot -d u-boot.dtb

  • 3d5a335ce   nand_spl: display warning message to inform the end of nand_spl ... Browse Code »
    276

    Now we have two different frameworks for doing the same thing.
    I'd like to propose to drop nand_spl framework.
    How about deleting it before v2014.07 release?

    In the interim, this commit will display a warning message
    when compiling nand_spl board.

    Now we have 19 nand_spl boards:

    MPC8315ERDB_NAND
    SIMPC8313_LP
    SIMPC8313_SP
    MPC8536DS_NAND
    MPC8569MDS_NAND
    MPC8572DS_NAND
    P1023RDS_NAND
    P1011RDB_NAND
    P1020RDB_NAND
    P2010RDB_NAND
    P2020RDB_NAND
    acadia_nand
    bamboo_nand
    canyonlands_nand
    glacier_nand
    haleakala_nand
    kilauea_nand
    rainier_nand
    sequoia_nand

    They must be ported to SPL before the deadline,
    otherwise they will be removed.
