  • f47b048b3   ppc4xx: Add lcd4_lwmon5 support ... Browse Code »

    This patch adds the fast booting LWMON5 derivat "lcd4_lwmon5".
    Its a stripped down version of the full blown lwmon5 support,
    without ECC, USB, POST and some other stuff. It used the newly
    introduced SPL infrastrucure for SPL from NOR flash booting
    on the PPC4xx.

    By setting the environment variable "boot_os" to "yes", Linux
    will be started from the SPL version. If not, the "normal"
    U-Boot will be started.

  • 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.

  • f0c0b3a9e   Fix incorrect use of getenv() before relocation ... Browse Code »

    A large number of boards incorrectly used getenv() in their board init
    code running before relocation. In some cases this caused U-Boot to
    hang when certain environment variables grew too long.
    Fix the code to use getenv_r().

    This patch includes the following changes for the lwmon5 board support:

    - Enable cache in SDRAM
    - Use common EHCI driver instead of the PPC4xx specific OHCI driver
    This can be done since only high-speed devices are connected.
    - Remove cached TLB entry again after ECC setup
    - Use correct define for cache enabling
    (CONFIG_4xx_DCACHE instead of CONFIG_SYS_ENABLE_SDRAM_CACHE)
    - Enable FIT image support

  • 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.

  • 25ddd1fb0   Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value ... Browse Code »

    CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
    being able to use "sizeof(struct global_data)" in assembler files.
    Recent experience has shown that manual synchronization is not
    reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into
    GENERATED_GBL_DATA_SIZE which gets automatically generated by the
    asm-offsets tool. In the result, all definitions of this value can be
    deleted from the board config files. We have to make sure that all
    files that reference such data include the new file.

    No other changes have been done yet, but it is obvious that similar
    changes / simplifications can be done for other, related macro
    definitions as well.

  • 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) {
    ...

    TLB defines, instead of defining their own macros.

  • 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.

  • 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

  • f62fb9994   Fix all linker script to handle all rodata sections ... Browse Code »

    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.
