  • Albert's rework of the linker scripts conflicted with Simon's making
    everyone use __bss_end. We also had a minor conflict over
    README.scrapyard being added to in mainline and enhanced in
    u-boot-arm/master with proper formatting.

  • 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.

  • 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 Thus the __u_boot_cmd section is now superseded and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 .

  • Add section for the linker-generated lists into all possible linker
    files, so that everyone can easily use these lists. This is mostly
    a mechanical adjustment.

  • 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.

  • This commit gets rid of a huge amount of silly white-space issues.
    Especially, all sequences of SPACEs followed by TAB characters get
    removed (unless they appear in print statements).

    Also remove all embedded "vim:" and "vi:" statements which hide
    indentation problems.

  • 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.
