  • 0defddc85   config: Add a default CONFIG_SYS_PROMPT ... Browse Code »
    86

    The definitions for CONFIG_SYS_PROMPT are varied with little reason other
    than to display the board name. Over half the definitions are "==> ", so
    make this the default. The rest of the boards remain unchanged to avoid
    breaking any external scripts expecting a certain prompt.

  • 3929fb0a1   Replace __bss_end__ with __bss_end ... Browse Code »

    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

  • 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.

  • 25ddd1fb0   Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value ... Browse Code »

    CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
    being able to use "sizeof(struct global_data)" in assembler files.
    Recent experience has shown that manual synchronization is not
    reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into
    GENERATED_GBL_DATA_SIZE which gets automatically generated by the
    asm-offsets tool. In the result, all definitions of this value can be
    deleted from the board config files. We have to make sure that all
    files that reference such data include the new file.

    No other changes have been done yet, but it is obvious that similar
    changes / simplifications can be done for other, related macro
    definitions as well.

    CONFIG_SYS_INIT_RAM_END was a misnomer as it suggests this might be

    No other code changes are performed in this patch, only minor editing
    of white space (due to the changed length) and the comments was done,
    where noticed.

    Note that the code for the PATI and cmi_mpc5xx board configurations
    looks seriously broken. Last known maintainers on Cc:

    Now that warm booting is not supported, there isn't a need for the
    BOOTFLAG_COLD and BOOTFLAG_WARM defines, so remove them.

    Note that this change makes the board info bd_bootflags field useless.
    It will always be set to 0, but we leave it around so that we don't
    break the board info structure that some OSes are expecting to be passed
    from U-Boot.

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

    is kept as an alias for now, to not break compatibility with

    - 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.

    Currently the mtdparts commands are included in the jffs2 command support.
    This doesn't make sense anymore since other commands (e.g. UBI) use this
    infrastructure as well now. This patch separates the mtdparts commands from
    the jffs2 commands making it possible to only select mtdparts when no JFFS2
    support is needed.

  • 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.

  • 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.
