  • 1a95d89f6   Blackfin: bf537-stamp: drop board reset workaround ... Browse Code »

    The bf537-stamp shouldn't need this SPI flash workaround. It was added
    by accident a long time ago through a convoluted series of steps which
    originated from a customer board (not the bf537-stamp). So drop it to
    keep people from incorrectly adding it to their own boards.

  • 464c79207   punt unused clean/distclean targets ... Browse Code »

    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.

  • 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.

    The common gpio code provides a function for handling the spi boot

    1

    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) {
    ...

  • 61f2b38a1   Replace "#include <asm-$ARCH/$FILE>" with "#include <asm/$FILE>" ... Browse Code »

    The appropriate include/asm-$ARCH directory should already by symlinked
    to include/asm so using the whole "asm-$ARCH" path is unnecessary.

    This change should also allow us to move the include/asm-$ARCH
    directories into their appropriate lib/$ARCH/ directories.

  • 89f39e177   Change directory-specific CFLAGS to use full path ... Browse Code »

    Previously, a specific file or directory could be compiled with custom
    CFLAGS by adding a Makefile variable such as:
    CFLAGS_dlmalloc.o =
    or
    CFLAGS_lib =

    This method breaks down once multiple files or directories share the
    same path. Eg FLAGS_fileA = would incorrectly result in
    both dir1/fileA.c and dir2/fileA.c being compiled with .

    This change allows finer grained control which we need once we move
    lib_$ARCH to arch/$ARCH/lib/ and lib_generic/ to lib/. Without this
    change all lib/ directories would share the same custom CFLAGS.

  • 9ff67e5e4   Blackfin: unify u-boot linker scripts ... Browse Code »

    All the Blackfin linker scripts were duplicated across the board dirs with
    no difference save from the semi-often used ENV_IS_EMBEDDED option. So
    unify all of them in the lib_blackfin/ dir and for the few boards that
    need to embedded the environment directly, add a LDS_BOARD_TEXT define for
    them to customize via their board config file. This is much simpler than
    forcing them to duplicate the rest of the linker script.

  • a89c33db9   General help message cleanup ... Browse Code »

    Many of the help messages were not really helpful; for example, many
    commands that take no arguments would not print a correct synopsis
    line, but "No additional help available." which is not exactly wrong,
    but not helpful either.

    Commit ``Make "usage" messages more helpful.'' changed this
    partially. But it also became clear that lots of "Usage" and "Help"
    messages (fields "usage" and "help" in struct cmd_tbl_s respective)
    were actually redundant.

    This patch cleans this up - for example:

    Before:
    => help dtt
    dtt - Digital Thermometer and Thermostat

    Usage:
    dtt - Read temperature from digital thermometer and thermostat.

    After:
    => help dtt
    dtt - Read temperature from Digital Thermometer and Thermostat

    Usage:
    dtt
