  • 686f60f51   lib: fix return codes when CONFIG_SYS_VSNPRINTF is enabled ... Browse Code »

    When CONFIG_SYS_VSNPRINTF is enabled, it protects print operations
    such as sprintf, snprintf, vsnprintf, etc., from buffer overflows.
    But vsnprintf_internal includes the terminating NULL character in
    the calculation of number of characters written. This affects sprintf
    and snprintf return values. Fix this issue by setting pointer 'str'
    back to the location of the '\0'.

  • de351d6be   lib: time: add weak timer_init() function ... Browse Code »

    If timer_init() is made a weak stub function, then it allows us to
    remove several empty timer_init functions for those boards that
    already have a timer initialized when u-boot starts. Architectures
    that use the timer framework may also remove the need for timer.c.

  • 4d3b8a0d1   lzma: fix buffer bound check error ... Browse Code »
    43

    Variable uncompressedSize references the space available, while outSizeFull is
    the actual expected uncompressed size. Using the wrong value causes LzmaDecode
    to return SZ_ERROR_INPUT_EOF. Problem was introduced in commit afca294. While
    at it add additional debug message.

  • 60d18d3fe   Add crc8 routine ... Browse Code »

    Add an implementation of the CRC8 algorithm. This is required by the TPM
    emulation, but is probably useful to U-Boot in general.

  • 2cd1b5722   time: fix usec_to_tick() ... Browse Code »

    Commit 8dfafdde88eb ("Introduce common timer functions") created a
    common definition of usec_to_tick() which had a couple problems:

    static unsigned long long usec_to_tick(unsigned long usec)
    {
    uint64_t tick = usec * get_tbclk();

    That likely overflows.

    usec *= get_tbclk();

    That was an attempt to fix it by performing the multiply after the
    promotion of usec to 64-bit, but was applied to the wrong variable,
    which was never used.

    This patch fixes these issues. A user-visible symptom of the problem was
    the e.g. "dhcp zImage" using an ASIX USB Ethernet dongle would print:

    Waiting for Ethernet connection... unable to connect.

    ... with no delay before "unable to connect". There are likely other
    symptoms.

  • 8dfafdde8   Introduce common timer functions ... Browse Code »
    197

    Many platforms duplicate pretty much the same timer code yet they all have
    a 32-bit freerunning counter register. Create a common implementation that
    minimally requires 2 or 3 defines to add timer support:

    CONFIG_SYS_TIMER_RATE - Clock rate of the timer counter
    CONFIG_SYS_TIMER_COUNTER - Address of 32-bit counter
    CONFIG_SYS_TIMER_COUNTS_DOWN - Define if counter counts down

    All functions are weak or ifdef'ed so they can still be overriden by any
    platform.

  • 2108f4c4a   config: consolidate CONFIG_SYS_HZ definition ... Browse Code »

    According to the README, CONFIG_SYS_HZ must be 1000 and most platforms
    follow that. In preparation to remove CONFIG_SYS_HZ from all these
    platforms, provide a common definition. The platforms which use a value
    other than 1000 will get build warning now. These configs are:

    include/configs/M5271EVB.h:#define CONFIG_SYS_HZ 1000000

  • be6c1529c   tpm: add AUTH1 cmds for LoadKey2 and GetPubKey ... Browse Code »

    Extend the tpm library with support for single authorized (AUTH1) commands
    as specified in the TCG Main Specification 1.2. (The internally used helper
    functions are implemented in a way that they could also be used for double
    authorized commands if someone needs it.)

    Provide enums with the return codes from the TCG Main specification.

    For now only a single OIAP session is supported.

    OIAP authorized version of the commands TPM_LoadKey2 and TPM_GetPubKey are
    provided. Both features are available using the 'tpm' command, too.

    Authorized commands are enabled with CONFIG_TPM_AUTH_SESSIONS. (Note that
    this also requires CONFIG_SHA1 to be enabled.)

  • 19c402afa   image: Add RSA support for image signing ... Browse Code »

    RSA provides a public key encryption facility which is ideal for image
    signing and verification.

    Images are signed using a private key by mkimage. Then at run-time, the
    images are verified using a private key.

    This implementation uses openssl for the host part (mkimage). To avoid
    bringing large libraries into the U-Boot binary, the RSA public key
    is encoded using a simple numeric representation in the device tree.

    this information can be sent to the host for processing.
