  • 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.

  • 2ae182419   Makefile: move all Power Architecture boards into boards.cfg ... Browse Code »

    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.

  • 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.

    since commit 1384f3bb8a4f9066805b70c1418eda78ecb73fdd ethernet names
    with spaces drop a

    Warning: eth device name has a space!

    message. This patch fix it for:

    - "FEC ETHERNET" devices found on
    mpc512x, mpc5xxx, mpc8xx and mpc8220 boards.
    renamed to "FEC".
    - "SCC ETHERNET" devices found on
    mpc8xx, mpc82xx based boards. Renamed to "SCC".
    - "HDLC ETHERNET" devices found on mpc8xx boards
    Renamed to "HDLC"
    - "FCC ETHERNET" devices found on mpc8260 and mpc85xx based
    boards. Renamed to "FCC"

    Tested on the kup4k board.

  • 54841ab50   Make sure that argv[] argument pointers are not modified. ... Browse Code »
    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) {
    ...

  • 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.

  • f93286397   Add support for a saving build objects in a separate directory. ... Browse Code »

    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.
