  • aa9fba531   smc91xx_eeprom: Correct chip detection check. ... Browse Code »

    The smc911x_detect function in /net/driver/net/smc911x.c
    returns a 0 if everything was ok (a chip was found) and -1 else.
    In the standalone example 'smc911x_eeprom' the return value
    of smc911x_detect is interpreted in a different way
    (0 for error, !0 as OK).
    This leads to the error that the chip will not be detected.

  • 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) {
    ...

  • 620bbba52   examples/standalone: Remove relocation compile flags for PowerPC ... Browse Code »

    Previously, standalone applications were compiled with gcc flags that
    produced relocatable executables on the PowerPC architecture (eg with
    the -mrelocatable and -fPIC flags). There's no reason for these
    applications to be fully relocatable at this time since no relocation
    fixups are performed on standalone applications.

    Additionally, removing the gcc relocation flags results in the entry
    point of applications residing at the base of the image. When
    a standalone application was relocatable, the entry point was generally
    located at an offset into the image which was confusing and prone to
    errors.

    This change moves the entry point of PowerPC standalone applications
    from 0x40004 (usually) to 0x40000.

    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.

    Building for a bf533-stamp ends up with this error:

    examples/standalone/smc91111_eeprom.c:58: undefined reference to `memset'
    make[2]: *** [smc91111_eeprom] Error 1

    The new eth_struct definition means gcc has to zero out the structure on
    the stack, and some gcc versions optimize this with an implicit call to
    memset. So tweak the structure style to avoid that gcc feature.

    According to the PPC reference implementation the udelay() function is
    responsible for resetting the watchdog timer as frequently as needed.
    Most other architectures do not meet that requirement, so long-running
    operations might result in a watchdog reset.

    This patch adds a generic udelay() function which takes care of
    resetting the watchdog before calling an architecture-specific
    __udelay().

    Some versions of 'make' do not handle trailing white-spaces

    Atmel DataFlashes by default operate with pages that are slightly bigger
    than normal binary sizes (i.e. many are 1056 byte pages rather than 1024
    bytes). However, they also have a "power of 2" mode where the pages show
    up with the normal binary size. The latter mode is required in order to
    boot with a Blackfin processor, so many people wish to convert their
    DataFlashes on their development systems to this mode. This standalone
    application does just that.

    Since the Blackfin ABI favors higher scratch registers by default, use the
    last scratch register (P3) for global data rather than the first (P5).
    This allows the compiler's register allocator to use higher number scratch
    P registers, which in turn better matches the Blackfin instruction set,
    which reduces the size of U-Boot by more than 1024 bytes...

    The attached patch corrects an error in the examples/Makefile which
    causes the applications in the examples directory to hang on OMAP3
    based boards. The current Makefile sets -Ttext during linking to
    0x0c100000 which is outside of addressable SDRAM memory. The script
    corrects the existing ifeq...else...endif logic to look at the VENDOR
    tag rather than the CPU tag.

    The patch affects the following configs: omap3_beagle_config,
    omap3_overo_config, omap3_evm_config, omap3_pandora_config,
    omap3_zoom1_config and omap3_zoom2_config.

  • 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.
