  • e895a4b06   fdt: Allow ft_board_setup() to report failure ... Browse Code »

    This function can fail if the device tree runs out of space. Rather than
    silently booting with an incomplete device tree, allow the failure to be
    detected.

    Unfortunately this involves changing a lot of places in the code. I have
    not changed behvaiour to return an error where one is not currently
    returned, to avoid unexpected breakage.

    Eventually it would be nice to allow boards to register functions to be
    called to update the device tree. This would avoid all the many functions
    to do this. However it's not clear yet if this should be done using driver
    model or with a linker list. This work is left for later.

  • e5a504eb3   MAINTAINERS: comment out invalid maintainers ... Browse Code »

    The "S: Orphan" in MAINTAINERS means that the maintainer in the
    "M:" field is unreachable (i.e. the email address is not working).
    (Refer to the definition of "Orphan" adopted in U-Boot
    in the log of commit 31f1b654b2f395b69faa5d0d3c1eb0803923bd3b,
    "boards.cfg: move boards with invalid emails to Orphan")

    For patch files adding global changes, scripts/get_maintainer.pl
    adds bunch of such invalid email addresses, which results in
    tons of annoying bounce emails.

    This commit can be reproduced by the following command:

    find . -name MAINTAINERS | xargs sed -i -e '
    /^M:[[:blank:]]/ {
    N
    /S:[[:blank:]]Orphan/s/^/#/
    }

  • 461be2f96   kconfig: remove redundant "string" type in arch and board Kconfigs ... Browse Code »
    44

    Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}
    are specified in arch/Kconfig.

    We can delete the ones in arch and board Kconfig files.

    This commit can be easily reproduced by the following command:

    find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e '
    /config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ {
    N

  • 93d4334f7   Add board MAINTAINERS files ... Browse Code »

    We have switched to Kconfig and the boards.cfg file is going to
    be removed. We have to retrieve the board status and maintainers
    information from it.

    The MAINTAINERS format as in Linux Kernel would be nice
    because we can crib the scripts/get_maintainer.pl script.

    After some discussion, we chose to put a MAINTAINERS file under each
    board directory, not the top-level one because we want to collect
    relevant information for a board into a single place.

    TODO:
    Modify get_maintainer.pl to scan multiple MAINTAINERS files.

  • dd84058d2   kconfig: add board Kconfig and defconfig files ... Browse Code »

    This commit adds:
    - arch/${ARCH}/Kconfig
    provide a menu to select target boards
    - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
    - configs/${TARGET_BOARD}_defconfig
    default setting of each board

    (This commit was automatically generated by a conversion script
    based on boards.cfg)

    In Linux Kernel, defconfig files are located under
    arch/${ARCH}/configs/ directory.
    It works in Linux Kernel since ARCH is always given from the
    command line for cross compile.

    But in U-Boot, ARCH is not given from the command line.
    Which means we cannot know ARCH until the board configuration is done.
    That is why all the "*_defconfig" files should be gathered into a
    single directory ./configs/.

    Note this is a tree-wide change affecting multiple architectures.

    At present we use __bss_start, but mostly __bss_end__. This seems
    inconsistent and in a number of places __bss_end is used instead.

    Change to use __bss_end for the BSS end symbol throughout U-Boot. This
    makes it possible to use the asm-generic/sections.h file on all
    archs.

    Refactor linker-generated array code so that symbols
    which were previously linker-generated are now compiler-
    generated. This causes relocation records of type
    R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
    code which uses LGA able to run before relocation as
    well as after.

    Note: this affects more than ARM targets, as linker-
    lists span possibly all target architectures, notably
    PowerPC.

  • c39f44dc6   powerpc/8xxx: Refactor fsl_ddr_get_spd into common code from board ... Browse Code »

    Move fsl_ddr_get_spd into common mpc8xxx/ddr/main.c as most boards
    pretty much do the same thing. The only variations are in how many
    controllers or DIMMs per controller exist. To make this work we
    standardize on the names of the SPD_EEPROM_ADDRESS defines based on the
    use case of the board.

    We allow boards to override get_spd to either do board specific fixups
    to the SPD data or deal with any unique behavior of how the SPD eeproms
    are wired up.

  • 38dba0c2f   mpc85xx boards: initdram() cleanup/bugfix ... Browse Code »

    Correct initdram to use phys_size_t to represent the size of
    dram; instead of changing this all over the place, and correcting
    all the other random errors I've noticed, create a
    common initdram that is used by all non-corenet 85xx parts. Most
    of the initdram() functions were identical, with 2 common differences:

    1) DDR tlbs for the fixed_sdram case were set up in initdram() on
    some boards, and were part of the tlb_table on others. I have
    changed them all over to the initdram() method - we shouldn't
    be accessing dram before this point so they don't need to be
    done sooner, and this seems cleaner.

    2) Parts that require the DDR11 erratum workaround had different
    implementations - I have adopted the version from the Freescale
    errata document. It also looks like some of the versions were
    buggy, and, depending on timing, could have resulted in the
    DDR controller being disabled. This seems bad.

    The xpedite boards had a common/fsl_8xxx_ddr.c; with this
    change only the 517 board uses this so I have moved the ddr code
    into that board's directory in xpedite517x.c

  • 6d8962e81   Switch from archive libraries to partial linking ... Browse Code »

    Before this commit, weak symbols were not overridden by non-weak symbols
    found in archive libraries when linking with recent versions of
    binutils. As stated in the System V ABI, "the link editor does not
    extract archive members to resolve undefined weak symbols".

    This commit changes all Makefiles to use partial linking (ld -r) instead
    of creating library archives, which forces all symbols to participate in
    linking, allowing non-weak symbols to override weak symbols as intended.
    This approach is also used by Linux, from which the gmake function
    cmd_link_o_target (defined in config.mk and used in all Makefiles) is
    inspired.

    The name of each former library archive is preserved except for
    extensions which change from ".a" to ".o". This commit updates
    references accordingly where needed, in particular in some linker
    scripts.

    This commit reveals board configurations that exclude some features but
    include source files that depend these disabled features in the build,
    resulting in undefined symbols. Known such cases include:
    - disabling CMD_NET but not CMD_NFS;
    - enabling CONFIG_OF_LIBFDT but not CONFIG_QE.
