  • 871a57bb8   common/cmd_bootm: extend do_bootm_vxworks to support the new VxWorks boot interface. ... Browse Code »

    The next version VxWorks adopts device tree (for PowerPC and ARM) as its hardware
    description mechanism. For PowerPC, the boot interface conforms to
    the ePAPR standard, which is:

    void (*kernel_entry)(ulong fdt_addr,
    ulong r4 /* 0 */,
    ulong r5 /* 0 */,
    ulong r6 /* EPAPR_MAGIC */, ulong r7 /* IMA size */,
    ulong r8 /* 0 */, ulong r9 /* 0 */)

    For ARM, the boot interface is:

    void (*kernel_entry)(void *fdt_addr)

  • 99bcad180   ppc4xx: Remove IOP480 support ... Browse Code »
    46

    Since the IOP480 (PPC401/3 variant from PLX) is only used on 2
    boards that are not actively maintained, lets remove support
    for it completely. This way the ppc4xx code will get a bit cleaner.

  • 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) {
    ...
