  • e543be2df   MA-15158 Set spl recovery mode for dual bootloader ... Browse Code »

    The A/B slot selection is moved to spl, it may lead to hang
    if no bootable slots found. The only way to recover the board
    is re-flash images with uuu tool, which is quite inconvenient
    for some customers who can't enter serial download mode.

    This patch will set "spl recovery mode" which will give us a
    chance to re-flash images with fastboot commands.

    Test: Enter spl recovery mode and flash images when no bootable
    slots found.

    On m68k, block_cache list is relocated, but next and prev list
    pointers are not adjusted to the relocated struct list_head address,
    so the first iteration over the block_cache list hangs.

    This patch initializes the block_cache list after relocation.

    At present the early timer init happens as soon as driver model is set up.
    This makes it impossible to do anything that needs driver model but must
    run before devices are probed (as needed with Intel's FSP-S, for example).

    In any case it is not a good idea to tie probing of particular drivers too
    closely to the DM init.

    Create a new function to init the timer and put it a bit later in the
    sequence.

  • ac9cd4805   bootstage: Correct relocation algorithm ... Browse Code »
    13

    At present bootstage relocation assumes that it is possible to point back
    to memory available before relocation, so it does not relocate the
    strings. However this is not the case on some platforms, such as x86 which
    uses the cache as RAM and loses access to this when the cache is enabled.

    Move the relocation step to before U-Boot relocates, expand the allocated
    region to include space for the strings and relocate the strings at the
    same time as the bootstage records.

    This ensures that bootstage data can remain accessible from TPL through
    SPL to U-Boot before/after relocation.

  • 5e0404ff8   board_f: fix noncached reservation calculation ... Browse Code »

    The current code in reserve_noncached() has two issues:

    1) The first update of gd->start_addr_sp always rounds down to a section
    start. However, the equivalent calculation in cache.c:noncached_init()
    always first rounds up to a section start, then subtracts a section size.
    These two calculations differ if the initial value is already rounded to
    section alignment.

    2) The second update of gd->start_addr_sp subtracts exactly
    CONFIG_SYS_NONCACHED_MEMORY, whereas the equivalent calculation in
    cache.c:noncached_init() rounds the noncached size up to section
    alignment before subtracting it. The two calculations differ if the
    noncached region size is not a multiple of the MMU section size.

    In practice, one/both of those issues causes a practical problem on
    Jetson TX1; U-Boot triggers a synchronous abort during initialization,
    likely due to overlapping use of some memory region.

    This change fixes both these issues by duplicating the exact calculations
    from noncached_init() into reserve_noncached().

    However, this fix assumes that gd->start_addr_sp on entry to
    reserve_noncached() exactly matches mem_malloc_start on entry to
    noncached_init(). I haven't traced the code to see whether it absolutely
    guarantees this in all (or indeed any!) cases. Consequently, I added some
    comments in the hope that this condition will continue to be true.

    Fixes: 5f7adb5b1c02 ("board_f: reserve noncached space below malloc area")

  • 84b2416b6   board_r: move initr_watchdog to be called after initr_serial ... Browse Code »

    The initr_watchdog is currently placed before initr_serial. The
    initr_watchdog calls printf and printf finally calls ops->putc of a serial
    driver.

    However, gd->cur_serial_dev points to a udevice allocated in board_f. The
    gd->cur_serial_dev->driver->ops->putc points the the code region before
    relocation.

    Some serial drivers call WATCHDOG_RESET() in ops->putc. When DM is enabled
    for watchdog, watchdog_reset() is called. watchdog_reset() calls get_timer
    to get current timer.

    On some platforms the timer driver is also a DM driver. initr_watchdog is
    placed right after initr_dm, which means the timer driver hasn't been
    initialized. So dm_timer_init() is called. To create a new udevice, calloc
    is called.

    However start from ops->putc, u-boot execution flow is redirected into the
    memory region before relocation (board_f). In board_f, dlmalloc hasn't
    been initialized. The call to calloc will fail, and this will cause DM to
    print out an error message, and it will call printf again, causing
    recursive error outputs.

    This patch places initr_watchdog after initr_serial to solve this issue.

  • 06985289d   watchdog: Implement generic watchdog_reset() version ... Browse Code »
    72

    This patch tries to implement a generic watchdog_reset() function that
    can be used by all boards that want to service the watchdog device in
    U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG.

    Without this approach, new boards or platforms needed to implement a
    board specific version of this functionality, mostly copy'ing the same
    code over and over again into their board or platforms code base.

    With this new generic function, the scattered other functions are now
    removed to be replaced by the generic one. The new version also enables
    the configuration of the watchdog timeout via the DT "timeout-sec"
    property (if enabled via CONFIG_OF_CONTROL).

    This patch also adds a new flag to the GD flags, to flag that the
    watchdog is ready to use and adds the pointer to the watchdog device
    to the GD. This enables us to remove the global "watchdog_dev"
    variable, which was prone to cause problems because of its potentially
    very early use in watchdog_reset(), even before the BSS is cleared.

  • e7ac009b0   efi_loader: move efi_save_gd() call to board_r.c ... Browse Code »

    The first functions of the UEFI sub-system are invoked before reaching the
    U-Boot shell, e.g. efi_set_bootdev(), efi_dp_from_name(),
    efi_dp_from_file(). We should be able to print out device paths for
    debugging purposes here.

    When printing device paths via printf("%pD\n", dp) this invokes functions
    defined as EFIAPI. So efi_save_gd() must be called beforehand.

    So let's move the efi_save_gd() call to function initr_reloc_global_data(()
    in board_r.c.

  • 47870afab   initcall: Move to inline function ... Browse Code »

    The board_r init function was complaining that we are looping through
    an array, calling all our tiny init stubs sequentially via indirect
    function calls (which can't be speculated, so they are slow).

    The solution to that is pretty easy though. All we need to do is inline
    the function that loops through the functions and the compiler will
    automatically convert almost all indirect calls into direct inlined code.

    With this patch, the overall code size drops (by 40 bytes on riscv64)
    and boot time should become measurably faster for every target.
