  • 3609e1dc5   dts: automatically build necessary .dtb files ... Browse Code »

    When building for a custom board, it is quite common to maintain a
    private branch which include some defconfig and .dts files. But to
    hook up those .dts files requires modifying a file "belonging" to
    upstream U-Boot, the arch/*/dts/Makefile. Forward-porting that branch
    to a newer upstream then often results in a conflict which, while it
    is trivial to resolve by hand, makes it harder to have a CI do "try to
    build our board against latest upstream".

    The .config usually includes information on precisely what .dtb(s) are
    needed, so to avoid having to modify the Makefile, simply add the
    files in (SPL_)OF_LIST to dtb-y.

    A technicality is that (SPL_)OF_LIST is not always defined, so rework
    the Kconfig symbols so that (SPL_)OF_LIST is always defined (when
    (SPL_)OF_CONTROL), but only prompted for in the cases which used to be
    their "depends on".

    nios2 and microblaze already have something like this in their
    dts/Makefile, and the rationale in commit 41f59f68539 is similar to
    the above. So this simply generalizes existing practice. Followup
    patches could remove the logic in those two makefiles, just as there's
    potential for moving some common boilerplate from all the
    arch/*/dts/Makefile files to the new scripts/Makefile.dts.

  • 3847ba94f   Finish converting CONFIG_WATCHDOG, HW_WATCHDOG and WDT to Kconfig ... Browse Code »

    Because of how these symbols work, and the remaining board config.h file
    uses, we need to do these at the same time. In some cases we just get
    to move rather directly to the defconfigs. A few cases require manual
    intervention.

    For the case of the eb_cpu5282 we need to select HW_WATCHDOG for the
    target, given how it's implemented.

    For the cases of m53menlo, dh_imx6, display5, and display5_factory we
    disable SPL watchdog support as the particular combination of options
    they want would require either more symbols or enabling SPL_DM.

  • 076c7bfb1   global_data: Ensure we have <config.h> when symbols are not in Kconfig yet ... Browse Code »

    All symbols that are defined in Kconfig will always be defined (or not)
    prior to preprocessing due to the -include directive while building.
    However, symbols which are not yet migrated will only be defined (or
    not) once the board config.h is included, via . While the end
    goal must be to migrate all symbols, today we have cases where the size
    of gd will get mismatched within the build, based on include order.
    Mitigate this by making sure that any that uses
    symbols not in Kconfig does start with . Remove this when not
    needed.

  • 933ada560   allow opting out of WATCHDOG_RESET() from timer interrupt ... Browse Code »

    Having WATCHDOG_RESET() called automatically from the timer interrupt
    runs counter to the idea of a watchdog device - if the board runs into
    an infinite loops with interrupts still enabled, the watchdog will
    never fire.

    When using CONFIG_(SPL_)WDT, the watchdog_reset function is a lot more
    complicated than just poking a few SOC-specific registers - it
    involves accessing all kinds of global data, and if the interrupt
    happens at the wrong time (say, in the middle of an WATCHDOG_RESET()
    call from ordinary code), that can end up corrupting said global data.

    Allow the board to opt out of calling WATCHDOG_RESET() from the timer
    interrupt handler by setting CONFIG_SYS_WATCHDOG_FREQ to 0 - as that
    setting is currently nonsensical (it would be compile-time
    divide-by-zero), it cannot affect any existing boards.

    Add documentation for both the existing and extended meaning of
    CONFIG_SYS_WATCHDOG_FREQ.

  • 98592c750   bdinfo: Rename function names to be clearer ... Browse Code »

    At present we have bdinfo_print_num() to print unsigned long numbers.
    We also have print_phys_addr() which accept numbers that might be
    64-bit on a 32-bit platform.

    Rename these 2 functions to be clearer:

    bdinfo_print_num() => bdinfo_print_num_l()
    print_phys_addr() => bdinfo_print_num_ll()

    While we are here, make bdinfo_print_num_ll() public so that it can
    be used outside cmd/bdinfo.c in the future.

    Move this out of the common header and include it only where needed. In
    a number of cases this requires adding "struct udevice;" to avoid adding
    another large header or in other cases replacing / adding missing header
    files that had been pulled in, very indirectly. Finally, we have a few
    cases where we did not need to include at all, so
    remove that include.

  • b75d8dc56   treewide: convert bd_t to struct bd_info by coccinelle ... Browse Code »

    The Linux coding style guide (Documentation/process/coding-style.rst)
    clearly says:

    It's a **mistake** to use typedef for structures and pointers.

    Besides, using typedef for structures is annoying when you try to make
    headers self-contained.

    Let's say you have the following function declaration in a header:

    void foo(bd_t *bd);

    This is not self-contained since bd_t is not defined.

    To tell the compiler what 'bd_t' is, you need to include

    #include
    void foo(bd_t *bd);

    Then, the include direcective pulls in more bloat needlessly.

    If you use 'struct bd_info' instead, it is enough to put a forward
    declaration as follows:

    struct bd_info;
    void foo(struct bd_info *bd);

    Right, typedef'ing bd_t is a mistake.

    I used coccinelle to generate this commit.

    The semantic patch that makes this change is as follows:


    @@
    typedef bd_t;
    @@
    -bd_t
    +struct bd_info
