  • 83d290c56   SPDX: Convert all of our single license tags to Linux Kernel style ... Browse Code »
    56

    When U-Boot started using SPDX tags we were among the early adopters and
    there weren't a lot of other examples to borrow from. So we picked the
    area of the file that usually had a full license text and replaced it
    with an appropriate SPDX-License-Identifier: entry. Since then, the
    Linux Kernel has adopted SPDX tags and they place it as the very first
    line in a file (except where shebangs are used, then it's second line)
    and with slightly different comment styles than us.

    In part due to community overlap, in part due to better tag visibility
    and in part for other minor reasons, switch over to that style.

    This commit changes all instances where we have a single declared
    license in the tag as both the before and after are identical in tag
    contents. There's also a few places where I found we did not have a tag
    and have introduced one.

  • b44b30260   printk: collect printk stuff into <linux/printk.h> with loglevel support ... Browse Code »

    When we import code from Linux, with regular re-sync planned, we want
    to use printk() and pr_*(). U-Boot does not support them in a clean
    way. So, people end up with local macros, or compat headers here and
    there, then we occasionally see build errors of definition conflicts.

    We have include/linux/compat.h, but putting all sorts of unrelated
    things into a single header is just a temporal workaround. Hence this
    patch, to find the best home for all printk variants. If you want to
    use printk() and friends, please include . This header
    is self-contained, and pulls in only a few headers.

    When I was testing this clean-up, I noticed the image size exceeded
    its platform limit on some boards. This is because all pr_*() that
    were previously defined as no-op in include/linux/mtd/mtd.h (unless
    CONFIG_MTD_DEBUG is set), are now enabled.

    To make such boards happy, this commit also implements CONFIG_LOGLEVEL.
    The concept is similar to the kernel parameter "loglevel". (Actually,
    the Kconfig help message was taken from kernel-paremeter.txt of Linux)
    Messages with a loglevel smaller than console loglevel will be printed.

    The difference is the loglevel is build-time determined. To save the
    image size, lower priority pr_*() are compiled out. I set the default
    of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages
    are compiled in.

    I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.

  • da58dec86   Various Makefiles: Add SPDX-License-Identifier tags ... Browse Code »
    40

    After consulting with some of the SPDX team, the conclusion is that
    Makefiles are worth adding SPDX-License-Identifier tags too, and most of
    ours have one. This adds tags to ones that lack them and converts a few
    that had full (or in one case, very partial) license blobs into the
    equivalent tag.

  • 6825a95b0   kbuild: use Linux Kernel build scripts ... Browse Code »

    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.

  • 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.

  • b2da80384   biosemu: include <asm/io.h> header ... Browse Code »

    This makes sure we have inline functions such as inb/outb that
    are used in these two files by including the arch-specific
    header. However the ARM version does not provide the
    accessors unless the config symbol __io is also defined so add
    that in front of the include.

    After this the bios emulator will compile on ARM systems.

    'bool' is defined in random places. This patch consolidates them into a
    single header file include/linux/types.h, using stdbool.h introduced in C99.

    All other #define, typedef and enum are removed. They are all consistent with
    true = 1, false = 0.

    Replace FALSE, False with false. Replace TRUE, True with true.
    Skip *.py, *.php, lib/* files.

  • 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.
