  • 965de8b91   ARM: AM33xx+: Update ioregs to pass different values ... Browse Code »

    Currently same value is programmed for all ioregs. This is not
    the case for all SoC's like AM4372. So adding a structure for ioregs
    and updating in all board files. And also return from config_cmd_ctrl()
    and config_ddr_data() functions if data is not passed.

  • 39245c869   am33xx: Stop modifying certain EMIF4D registers ... Browse Code »

    Based on the definitive guide to EMIF configuration[1] certain registers
    that we have been modifying (and are documented registers) should be
    left in their reset values rather than modified. This has been tested
    on AM335x GP EVM and Beaglebone White.

  • 56eb3da43   arm, am335x: update for the siemens boards ... Browse Code »

    - dxr2: define unused pins as input
    - do not enable RTC32K OSC on dxr2 board
    - update default environment
    - add splashpos=m,m to default environment, so splash screen is always
    centered.
    - adapt environment for bootcount feature
    - add altbootcmd to default environment
    - rut: SPL add early reset pulse for eth-phy, maXTouch and display
    - rut: display timing aenderungen
    - siemens boards: adapt for background color = white
    - add boutcount feature for the siemens boards
    store the bootcount in the environment, as we have no softreset
    save registers on this hardware. Use therefore the CONFIG_BOOTCOUNT_ENV
    bootcount driver.
    - change spi mode from 3 to 0 for the lcd init
    - add gpio pin for lcd reset with state 0 and add mdelay
    - siemens boards: use own USB id's
    - add dfu serial and device number for siemens boards
    Add for the siemens boards the possibility to define in dfu mode,
    the iSerialNumber and the bcdDevice fields in the USB Device
    descriptor.
    - fix upgrade mechanism based on bootcount
    Correct location of saveenv and remove not active variable.

    Add CONFIG_BOOT_RETRY_TIME and CONFIG_RESET_TO_RETRY to
    reboot board in case of empty kernel partition. Without
    these defines an empty kernel partition leads to an
    abort of boot process and one remains in u-boot prompt.

    - general cleanup of dxr2, pxm2 and rut boards
    all:
    * Remove net boot from bootcmd
    Ping can cause a crash on boards without ethernet phy.
    net_nfs command is used only for development

    * Add reset at the end of bootcmd
    In order to have an immediate reset of the boot when bootcmd
    fails, add reset at the end of bootcmd.

    rut:
    * add nand_img_size

    dxr2:
    * update nand_img_size

    * ddr3 timings updated with iocontrol property that can be
    modified via eeprom. New default parameters from software
    leveling with draco ES2.

  • cca4e4aec   Reduce build times ... Browse Code »

    U-Boot Makefiles contain a number of tests for compiler features etc.
    which so far are executed again and again. On some architectures
    (especially ARM) this results in a large number of calls to gcc.

    This patch makes sure to run such tests only once, thus largely
    reducing the number of "execve" system calls.

    Example: number of "execve" system calls for building the "P2020DS"
    (Power Architecture) and "qong" (ARM) boards, measured as:
    -> strace -f -e trace=execve -o /tmp/foo ./MAKEALL
    -> grep execve /tmp/foo | wc -l

    Before: After: Reduction:
    ==================================
    P2020DS 20555 15205 -26%
    qong 31692 14490 -54%

    As a result, built times are significantly reduced, typically by
    30...50%.

  • 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.

  • cdb749778   Rename getenv_r() into getenv_f() ... Browse Code »

    While running from flash, i. e. before relocation, we have only a
    limited C runtime environment without writable data segment. In this
    phase, some configurations (for example with environment in EEPROM)
    must not use the normal getenv(), but a special function. This
    function had been called getenv_r(), with the idea that the "_r"
    suffix would mean the same as in the _r_eentrant versions of some of
    the C library functions (for example getdate vs. getdate_r, getgrent
    vs. getgrent_r, etc.).

    Unfortunately this was a misleading name, as in U-Boot the "_r"
    generally means "running from RAM", i. e. _after_ relocation.

    To avoid confusion, rename into getenv_f() [as "running from flash"]

    Lots of code use this construct:

    return 1;

    Change cmd_usage() let it return 1 - then we can replace all these

    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) {
    ...

  • 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
