  • 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.

  • Allow L1 Icache & L1 Dcache line size to be specified separately, since
    there's no architectural mandate that they be the same. The
    [id]cache_line_size functions are tidied up to take advantage of the
    fact that the Kconfig entries are always present to simply check them
    for zero rather than needing to #ifdef on their presence.

  • Move details of the L1 cache line sizes & total sizes into Kconfig,
    defaulting to 0. A new CONFIG_SYS_CACHE_SIZE_AUTO Kconfig entry is
    introduced to allow platforms to select auto-detection of cache sizes,
    and it defaults to being enabled if none of the cache sizes are set by
    the configuration (ie. sizes are all the default 0), and code is
    adjusted to #ifdef on that rather than on the definition of the sizes
    (which will always be defined even if 0).

  • Move CONFIG_SYS_TEXT_BASE to Kconfig, and add default values in board
    Kconfig files matching what was present in their config headers. This
    will make it cleaner to conditionalise the value for Malta based on 32
    vs 64 bit builds.

  • Since commit ddaf5c8f3030050fcd356a1e49e3ee8f8f52c6d4
    (patman: RunPipe() should not pipe stdout/stderr unless asked),
    Patman spits lots of "Invalid MAINTAINERS address: '-'"
    error messages for patches with global changes.
    It takes too long for Patman to process them.

    Anyway, "M: -" does not carry any important information.
    Rather, it is just like a place holder in case of assigning
    a new board maintainer. Let's comment out.

    This commit can be reproduced by the following command:

    find . -name MAINTAINERS | xargs sed -i -e '/^M:[[:blank:]]*-$/s/^/#/'

  • 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.

  • 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/.

  • Using the example command from the README file does
    not work as expected. qemu shows a text similar to
    the one below and it hangs.

    $ qemu-system-mips -L . -nographic
    Could not open option rom 'pxe-pcnet.rom': No such file or directory
    qemu-system-mips: pci_add_option_rom: failed to find romfile "vgabios-cirrus.bin"
    qemu: terminating on signal 15 from pid 19726

    This happens because qemu emulates a Malta board by
    default if the machine type is not defined explicitely
    on the command line.

    For a working test, the '-M mips' switch is required:

    $ qemu-system-mips -M mips -L . -nographic

  • The 'Limitations & comments' section refers to the
    '-m mips' switch which is not valid. The '-m' switch
    can be used for setting the virtual RAM size:

    $qemu-system-mips --help | grep '^-m '
    -m megs set virtual RAM size to megs MB [default=128]
    $

    The correct switch for specifying the machine type is '-M'.
    Fix the text to refer to that.

  • This fixes the build of the two sh boards shmin and r7780mp and qemu-mips
    which currently fail to build due to dropped pre-CONFIG_NET_MULTI code.

    This v2 patch minimizes the number of lines in the diff for easy review
    and to eliminate any possible accidential changes resulting from moving
    lines of code in the file. This also makes the register function very easy.

    Any cleanups and improvements are intentionally deferred to follow-up patches
    to keep this patch as simple and as easy to review as possible.

    A new driver register function, ne2k_register() calls the existing
    one-time setup part of the old init function and calls eth_register().

    Changes to shmin, r7780mp and qemu-mips:
    - Call the new ne2k_register() from board_eth_init() of the boards.

    - Tested using qemu-mips board,
    - Tested the two renesas / sh boards r7780mp and shmin to compile again,
    and should work.

    checkpatch-clean when "--ignore VOLATILE" is added to .checkpatch.conf,
    and no warnings introduced in none of the three boards using this driver.

  • 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.

  • The change is currently needed to be able to remove the board
    configuration scripting from the top level Makefile and replace it by
    a simple, table driven script.

    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.

  • 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.

  • This patch changes the return type of initdram() from long int to phys_size_t.
    This is required for a couple of reasons: long int limits the amount of dram
    to 2GB, and u-boot in general is moving over to phys_size_t to represent the
    size of physical memory. phys_size_t is defined as an unsigned long on almost
    all current platforms.

    This patch *only* changes the return type of the initdram function (in
    include/common.h, as well as in each board's implementation of initdram). It
    does not actually modify the code inside the function on any of the platforms;
    platforms which wish to support more than 2GB of DRAM will need to modify
    their initdram() function code.

    Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
    MPC8641HPCN.

  • Current assembler codes are inconsistent in the way of register jump
    instruction usage; some use jr, some use j. Of course GNU as allows both
    usages, but as can be expected from `Jump Register' the mnemonic `jr' is

    at all.
