  • b831bb36b   board: sandburst: delete FORCEBUILD ... Browse Code »

    We had switched to Kbuild, so we do not need to
    delete sandburst board files at every build.

    U-Boot conventional build system did not check the
    update of command line option, -DBUILDUSER.

    Kbuild can handle it nicely and re-builds object files
    when command line options are changed.
    (The file ".*.cmd" stores the information how the file
    was generated at the previous build.)

  • 6825a95b0   kbuild: use Linux Kernel build scripts ... Browse Code »

    Now we are ready to switch over to real Kbuild.

    This commit disables temporary scripts:
    scripts/{Makefile.build.tmp, Makefile.host.tmp}
    and enables real Kbuild scripts:
    scripts/{Makefile.build,Makefile.host,Makefile.lib}.

    This switch is triggered by the line in scripts/Kbuild.include
    -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
    +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj

    We need to adjust some build scripts for U-Boot.
    But smaller amount of modification is preferable.

    Additionally, we need to fix compiler flags which are
    locally added or removed.

    In Kbuild, it is not allowed to change CFLAGS locally.
    Instead, ccflags-y, asflags-y, cppflags-y,
    CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
    are prepared for that purpose.

  • ef123c525   Refactor linker-generated arrays ... Browse Code »

    Refactor linker-generated array code so that symbols
    which were previously linker-generated are now compiler-
    generated. This causes relocation records of type
    R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
    code which uses LGA able to run before relocation as
    well as after.

    Note: this affects more than ARM targets, as linker-
    lists span possibly all target architectures, notably
    PowerPC.

  • 8b493a523   common: Discard the __u_boot_cmd section ... Browse Code »

    The command declaration now uses the new LG-array method to generate
    list of commands. Thus the __u_boot_cmd section is now superseded and
    redundant and therefore can be removed. Also, remove externed symbols
    associated with this section from include/command.h .

  • 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.

    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.

  • 550650ddd   ppc4xx: Use common NS16550 driver for PPC4xx UART ... Browse Code »

    This patch removes the PPC4xx UART driver. Instead the common NS16550
    driver is used, since all PPC4xx SoC's use this peripheral device.

    The file 4xx_uart.c now only implements the UART clock calculation
    function which also sets the SoC internal UART divisors.

    All PPC4xx board config headers are changed to use this common NS16550
    driver now.

    Tested on these boards:
    acadia, canyonlands, katmai, kilauea, sequoia, zeus

  • 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) {
    ...

    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.

    This patch adds new macros, with frequently used combinations of the
    4xx TLB access control and storage attibutes. Additionally the 4xx init.S
    files are updated to make use of these new macros. Resulting in easier
    to read TLB definitions.

    Additionally some init.S files are updated to use the mmu header for the
    TLB defines, instead of defining their own macros.

    ppc4xx: Cleanup PPC4xx I2C infrastructure

    - Use C struct to describe the I2C registers instead of defines
    - Coding style cleanup (braces, whitespace, comments, line length)
    - Extract common code from i2c_read() and i2c_write()
    - Remove unneeded IIC defines from ppc405.h & ppc440.h

    breaks comiling for the KAREF and METROBOX boards.

    This patch fixes this issue.

  • d1c3b2752   ppc4xx: Big cleanup of PPC4xx defines ... Browse Code »

    This patch cleans up multiple issues of the 4xx register (mostly
    DCR, SDR, CPR, etc) definitions:

    - Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
    - Change the defines to better match the names from the
    user's manuals (e.g. cprpllc -> CPR0_PLLC)
    - Removal of some unused defines

    Please test this patch intensive on your PPC4xx platform. Even though
    I tried not to break anything and tested successfully on multiple
    4xx AMCC platforms, testing on custom platforms is recommended.
