  • The top level Makefile does not do any recursion into subdirs when
    cleaning, so these clean/distclean targets in random arch/board dirs
    never get used. Punt them all.

    MAKEALL didn't report any errors related to this that I could see.

    do_reset: unify duplicate prototypes

    missed the 74xx_7xx and mpc86xx arches and the ppmc7xx board do_reset()
    functions which resulted in build errors such as:
    cpu.c:128: error: conflicting types for 'do_reset'
    include/command.h:102: error: previous declaration of 'do_reset' was here

  • Recent cleanup actions resulted in a number of config.mk files that
    contained only redundant entries like

    PLATFORM_CPPFLAGS += -I$(TOPDIR)

    or settings of variables that were not used anywhere in the code, like

    TEXT_END = 0xfe080000

    Remove these unnecessary files.

  • 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.

  • Clean up Makefile, and drop a lot of the config.mk files on the way.

    We now also automatically pick all boards that are listed in
    boards.cfg (and with all configurations), so we can drop the redundant
    entries from MAKEALL to avoid building these twice.

  • 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.

  • The hush shell dynamically allocates (and re-allocates) memory for the
    argument strings in the "char *argv[]" argument vector passed to
    commands. Any code that modifies these pointers will cause serious
    corruption of the malloc data structures and crash U-Boot, so make
    sure the compiler can check that no such modifications are being done
    by changing the code into "char * const argv[]".

    This modification is the result of debugging a strange crash caused
    after adding a new command, which used the following argument
    processing code which has been working perfectly fine in all Unix
    systems since version 6 - but not so in U-Boot:

    int main (int argc, char **argv)
    {
    while (--argc > 0 && **++argv == '-') {
    /* ====> */ while (*++*argv) {
    switch (**argv) {
    case 'd':
    debug++;
    break;
    ...
    default:
    usage ();
    }
    }
    }
    ...
    }

    The line marked "====>" will corrupt the malloc data structures and
    usually cause U-Boot to crash when the next command gets executed by
    the shell. With the modification, the compiler will prevent this with
    an
    error: increment of read-only location '*argv'

    N.B.: The code above can be trivially rewritten like this:

    while (--argc > 0 && **++argv == '-') {
    char *arg = *argv;
    while (*++arg) {
    switch (*arg) {
    ...

  • As discussed on the list, move "arch/ppc" to "arch/powerpc" to
    better match the Linux directory structure.

    Please note that this patch also changes the "ppc" target in
    MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
    is kept as an alias for now, to not break compatibility with
    scripts using this name.

  • The following changes allow U-Boot to fully relocate from flash to
    RAM:
    - 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.

  • 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.

  • 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.

  • 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.
