  • b56ca8ced   MIPS: pb1x00: remove custom u-boot.lds script ... Browse Code »

    Remove the board specific linker script. It is not
    needed anymore, the unified MIPS linker script can
    be used instead.

    All pb1x00 targets are producing identical binary
    images after the change than before.

  • 9950b90d3   MIPS: remove OUTPUT_FORMAT from linker scripts ... Browse Code »

    The OUTPUT_FORMAT command in linker scripts
    was always misused due to some endianess and
    toolchain problems.

    Use GCC flags to ensure proper output format,
    and get rid of the OUTPUT_FORMAT commands in
    the board specific u-boot.lds files.

    The command declaration now uses the new LG-array method to generate
    list of commands. Thus the __u_boot_cmd section is now superseded and
    redundant and therefore can be removed. Also, remove externed symbols
    associated with this section from include/command.h .

    a mechanical adjustment.

  • 660da0947   MIPS: Introduce --gc-sections for MIPS ... Browse Code »

    All architectures but MIPS are using --gc-sections on final linking.
    This patch introduces that feature for MIPS to reduce the memory and

  • 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.

  • 14d0a02a1   Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE ... Browse Code »

    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.

    From the document, if set all arguments in "OUTPUT_FORMAT" to
    "tradbigmips", then even add "-EL" to gcc we still get EB format.

    pb1x00 is only used in Little-endian, so its default endian should be
    set to LE.

  • 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.

    Most of the bss initialization loop increments 4 bytes
    at a time. And the loop end is checked for an 'equal'
    condition. Make the bss end address aligned by 4, so
    that the loop will end as expected.

  • 9973e3c61   Change initdram() return type to phys_size_t ... Browse Code »

    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.

  • 43c509254   Use jr as register jump instruction ... Browse Code »

    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
    more intuitive than `j'. For example, Linux doesn't have `j ' usage
    at all.

  • 64134f011   Fix linker scripts: add NOLOAD atribute to .bss/.sbss sections ... Browse Code »
    20

    With recent toolchain versions, some boards would not build because
    or errors like this one (here for ocotea board when building with
    ELDK 4.2 beta):
    ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]

    For many boards, the .bss section is big enough that it wraps around
    at the end of the address space (0xFFFFFFFF), so the problem will not
    be visible unless you use a 64 bit tool chain for development. On
    some boards however, changes to the code size (due to different
    optimizations) we bail out with section overlaps like above.

    The fix is to add the NOLOAD attribute to the .bss and .sbss
    sections, telling the linker that .bss does not consume any space in
    the image.

  • f93286397   Add support for a saving build objects in a separate directory. ... Browse Code »

    Modifications are based on the linux kernel approach and
    support two use cases:

    1) Add O= to the make command line
    'make O=/tmp/build all'

    2) Set environement variable BUILD_DIR to point to the desired location
    'export BUILD_DIR=/tmp/build'
    'make'

    The second approach can also be used with a MAKEALL script
    'export BUILD_DIR=/tmp/build'
    './MAKEALL'

    Command line 'O=' setting overrides BUILD_DIR environent variable.

    When none of the above methods is used the local build is performed and
    the object files are placed in the source directory.
