  • 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.

    Recent cleanup actions resulted in a number of config.mk files that
    contained only LDSCRIPT definitions. Move these into th respective

  • 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.

  • 1211a4648   config.mk cleanup: drop "-I$(TOPDIR)/board" entries ... Browse Code »

    After the recent cleanups, a number of config.mk files consist only of
    a "PLATFORM_CPPFLAGS += -I$(TOPDIR)/board" entry whih is not needed.
    Remove such entries. In most cases, that means that the whole
    config.mk file can be removed.

  • 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.

  • cdb749778   Rename getenv_r() into getenv_f() ... Browse Code »

    While running from flash, i. e. before relocation, we have only a
    limited C runtime environment without writable data segment. In this
    phase, some configurations (for example with environment in EEPROM)
    must not use the normal getenv(), but a special function. This
    function had been called getenv_r(), with the idea that the "_r"
    suffix would mean the same as in the _r_eentrant versions of some of
    the C library functions (for example getdate vs. getdate_r, getgrent
    vs. getgrent_r, etc.).

    Unfortunately this was a misleading name, as in U-Boot the "_r"
    generally means "running from RAM", i. e. _after_ relocation.

    To avoid confusion, rename into getenv_f() [as "running from flash"]

  • 47e26b1bf   cmd_usage(): simplify return code handling ... Browse Code »

    Lots of code use this construct:

    cmd_usage(cmdtp);
    return 1;

    Change cmd_usage() let it return 1 - then we can replace all these
    ocurrances by

    return cmd_usage(cmdtp);

    This fixes a few places with incorrect return code handling, too.

  • 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) {
    ...

  • a47a12bec   Move arch/ppc to arch/powerpc ... Browse Code »

    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.

  • 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

  • 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.
