  • efcf86193   kbuild: use scripts/Makefile.clean ... Browse Code »
    43

    This commit refactors cleaning targets such as
    clean, clobber, mrpropper, distclean
    with scripts/Makefile.clean.

    By using scripts/Makefile.clean, we can recursively descend
    into subdirectories and delete generated files there.

    We do not need add a big list of generated files
    to the "clean" target.

  • 9e4140329   kbuild: change out-of-tree build ... Browse Code »
    43

    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.

  • 1b387ef55   SPDX: fix IBM-pibs license identifier ... Browse Code »

    The SPDX License List version 1.19 now contains an official entry for
    the IBM-pibs license. However, instead of our suggestion "ibm-pibs",
    the SPDX License List uses "IBM-pibs", with the following rationale:
    "The reason being that all other SPDX License List short identifiers
    tend towards using capital letters unless spelling a word. I'd prefer
    to be consistent to this end".

    Change the license IDs to use the official name.

  • 46263f2de   SPDX-License-Identifier: convert PIBS licensed files ... Browse Code »

    This commit adapts the files that were derived from PIBS (PowerPC
    Initialization and Boot Software) codeto using SPDX License
    Identifiers.

    So far, SPDX has not assigned an official License ID for the PIBS
    license yet, so this should be considered preliminary.

    Note that the following files contained incorrect license information:

    arch/powerpc/cpu/ppc4xx/4xx_uart.c
    arch/powerpc/cpu/ppc4xx/start.S
    arch/powerpc/include/asm/ppc440.h

    These files included, in addition to the GPL-2.0 / ibm-pibs dual
    license as inherited from PIBS, a GPL-2.0+ license header which was
    obviously incorrect. This has been removed.

  • ef123c525   Refactor linker-generated arrays ... Browse Code »

    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.

  • 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.

    Moving this configuration setting into the "CONFIG_*" name space is
    also desirable because it is needed if we ever should move forward to
    a Kconfig driven configuration system.

  • cdb749778   Rename getenv_r() into getenv_f() ... Browse Code »

    While running from flash, i. e. before relocation, we have only a
    limited C runtime environment without writable data segment. In this
    phase, some configurations (for example with environment in EEPROM)
    must not use the normal getenv(), but a special function. This
    function had been called getenv_r(), with the idea that the "_r"
    suffix would mean the same as in the _r_eentrant versions of some of
    the C library functions (for example getdate vs. getdate_r, getgrent
    vs. getgrent_r, etc.).

    Unfortunately this was a misleading name, as in U-Boot the "_r"
    generally means "running from RAM", i. e. _after_ relocation.

    To avoid confusion, rename into getenv_f() [as "running from flash"]

    Please note that this patch also changes the "ppc" target in

    is kept as an alias for now, to not break compatibility with
    scripts using this name.

    - Remove linker scripts' .fixup sections from the .text section
    - Add -mrelocatable to PLATFORM_RELFLAGS for all boards
    - Define CONFIG_RELOC_FIXUP_WORKS for all boards

    Previously, U-Boot would partially relocate, but statically initialized
    pointers needed to be manually relocated.

    This patch cleans up multiple issues of the 4xx register (mostly
    DCR, SDR, CPR, etc) definitions:

    - Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
    - Change the defines to better match the names from the
    user's manuals (e.g. cprpllc -> CPR0_PLLC)
    - Removal of some unused defines

    Please test this patch intensive on your PPC4xx platform. Even though
    I tried not to break anything and tested successfully on multiple
    4xx AMCC platforms, testing on custom platforms is recommended.

    It was brought to our attention that U-Boot contains code derived from the
    IBM OpenBIOS source code originally provided with some of the older PowerPC
    4xx development boards. As a result, the original license of this code has
    been carried in the various files for a number of years in the U-Boot project.

    IBM is dual-licensing the IBM code contributions already present in U-Boot
    under either the terms of the GNU General Public License version 2, or the
    original code license already present.

  • 74de7aefd   Add "source" command; prepare removal of "autoscr" command ... Browse Code »

    According to the doc/feature-removal-schedule.txt, the "autoscr"
    command will be replaced by the "source" command in approximately 6
    months from now.

    This patch prepares this change and starts a 6 month transition
    period as follows:

    - The new "source" command has been added, which implements exactly
    the same functionlaity as the old "autoscr" command before
    - The old "autoscr" command name is kept as an alias for compatibility
    - Command sequences, script files atc. have been adapted to use the
    new "source" command
    - Related environment variables ("autoscript", "autoscript_uname")
    have *not* been adapted yet; these will be renamed resp. removed in
    a separate patch when the support for the "autoscr" command get's
    finally dropped.

  • f62fb9994   Fix all linker script to handle all rodata sections ... Browse Code »

    A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
    which needs to be added the the linker script. Instead of just adding this
    one section, we use a wildcard ".rodata*" to get all rodata linker section
    gcc has now and might add in the future.

    However, '*(.rodata*)' by itself will result in sub-optimal section
    ordering. The sections will be sorted by object file, which causes extra
    padding between the unaligned rodata.str.1.1 of one object file and the
    aligned rodata of the next object file. This is easy to fix by using the
    SORT_BY_ALIGNMENT command.

    This patch has not be tested one most of the boards modified. Some boards
    have a linker script that looks something like this:

    *(.text)
    . = ALIGN(16);
    *(.rodata)
    *(.rodata.str1.4)
    *(.eh_frame)

    I change this to:

    *(.text)
    . = ALIGN(16);
    *(.eh_frame)
    *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))

    This means the start of rodata will no longer be 16 bytes aligned.
    However, the boundary between text and rodata/eh_frame is still aligned to
    16 bytes, which is what I think the real purpose of the ALIGN call is.
