  • e05e5de7f   arm: move C runtime setup code in crt0.S ... Browse Code »

    Move all the C runtime setup code from every start.S
    in arch/arm into arch/arm/lib/crt0.S. This covers
    the code sequence from setting up the initial stack
    to calling into board_init_r().

    Also, rewrite the C runtime setup and make functions
    board_init_*() and relocate_code() behave according to
    normal C semantics (no jumping across the C stack any
    more, etc).

    Some SPL targets had to be touched because they use
    start.S explicitly or for some reason; the relevant
    maintainers and custodians are cc:ed.

  • 448217d4b   arm: Fix to mistake clean the memory space ... Browse Code »

    In currently, when __bss_start is equal to __bss_end__,
    The bss loop will clear all the things in memory space.

    But just only when __bss_end__ greater than __bss_start__,
    we do the clear bss section operation.

  • e03f31697   Drop support for CONFIG_SKIP_RELOCATE_UBOOT ... Browse Code »

    For ARM systems, before ELF relocation was introduced,
    CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the
    U-Boot image from whereever it was loaded to it's link address
    (CONFIG_SYS_TEXT_BASE). The name was badly chosen, as no relocation
    was performed at all, it was just a memcpy().

    With ELF relocation, this does not work like that any more, and
    related boards need to be fixed anyway. So don't keep this relict any
    longer.

  • a9aa39262   Drop support for CONFIG_SYS_ARM_WITHOUT_RELOC ... Browse Code »

    When this define was introduced, the idea was to provide a soft
    migration path for ARM boards to get adapted to the new relocation
    support. However, other recent changes led to a different
    implementation (ELF relocation), where this no longer works. By now
    CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
    actually hurts because it obfuscates the actual code by sprinkling it
    with lots of dead and non-working debris.

    So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.

  • 79e631393   ARM: use the same branch insn on all architectures ... Browse Code »

    For the "fixloop" implementation in start.S a number of different
    instructions was used. Unify code so all architectures use "blo"
    here because it is more robust in case of incorrect alignments.

  • 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.

  • 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.

  • 1a27f7d9c   ARM: Align stack to 8 bytes ... Browse Code »

    The ARM ABI requires that the stack be aligned to 8 bytes as it is noted
    in Procedure Call Standard for the ARM Architecture:
    http://infocenter.arm.com/help/topic/com.arm.doc.ihi0042d/index.html

    Unaligned SP also causes the problem with variable-length arrays
    allocation when VLA address becomes less than stack pointer during
    aligning of this address, so the next 'push' in the stack overwrites
    first 4 bytes of VLA.
