  • While we setup the mmu initially we mark set_section_dcache with
    DCACHE_OFF flag. In case of non-LPAE mode the DCACHE_OFF macro
    is rightly defined with TTB_SECT_XN_MASK set so as to mark all the
    4GB XN. In case of LPAE mode XN(Execute-never) bit is not set with
    DCACHE_OFF. Hence XN bit is not set by default for DCACHE_OFF which
    keeps all the regions execute okay and this leads to random speculative
    fetches in random memory regions which was eventually caught by kernel
    omap-l3-noc driver.

    Fix this to mark the regions as XN by default.

  • If the MAC address specified on the EEPROM is invalid (multicast or
    zero address), then u-boot fails to boot. Having a bad MAC address
    in the EEPROM should not prevent the system from booting.

    This commit changes the error path to just print an error messages
    in case of bad MAC address.

  • In most cases, the SPL and u-boot.img will be on the same boot media.
    Since the SPL was loaded by the boot rom, the pinmux will already have
    been configured for this media. This, the board will still be able to
    boot successfully, or at least reach the u-boot console, where more
    recovery options are available.

    I've encountered this on a beaglebone black with a corrupted EEPROM.
    Removing this check allowed the board to boot successfully. I've also
    seen this on EVM-based boards with an unprogrammed EEPROM. On those
    boards, for some reason there were no UART messages. This made it look
    as if the SOC was dead.

    Remove the hang(), as it is not a fatal error. Also reformat the error
    message to be clearer as to the cause. The original message made it
    appear as if the wrong binary was being loaded.

  • Commit fed329aebe3a ("tools: add mksunxiboot to tools-all target") added

  • When performing a cache disable function, code must not access DRAM.
    That is because when the cache is disabled, it will be bypassed and all
    loads and stores will be serviced by RAM. This prevents accessing any
    dirty data in the cache. In turn, this means the stack cannot be
    used, since that is in RAM. To guarantee that code doesn't use RAM (and
    in particular the stack) __asm_flush_l3_cache() must be manually
    implemented in assembly, rather than implemented in C since the compiler
    won't know not to touch RAM.

  • Since commit ce412b79e7255770 ("drivers: net: phy: atheros: add separate

    This commit correctly assigns ar8031_config() as the configuration
    function for AR8031 in the same way as done in the Linux kernel.

    However, on wandboard design we need some additional configuration,
    such as enabling the 125 MHz AR8031 output that needs to be done
    in the board file.

    This also aligns with the same method that the kernel performs

  • The way that we have things broken down currently allows for some

    the sake of simplicity we are allowing for the possibility of some
    overlap between the vendor-based jobs and the CPU-based jobs. While
    we're in here, make a failed build provide the summary of failure.

  • For 64-bit ARM systems we provide just a timer_read_counter()
    implementation and rely on the generic non-uclass get_ticks() function
    in lib/time.c to call the former.
    However this function is actually not 64-bit safe, as it assumes a
    "long" to be 32-bit. Beside the fact that the resulting uint64_t
    isn't bigger than "long" on 64-bit architectures and thus combining two
    counters makes no sense, we get all kind of weird results when we try
    to OR in the high value shifted by _32_ bits.
    So let's avoid that function at all and provide a straight forward
    get_ticks() implementation for ARMv8, which also is in line with ARMv7.

    This fixes occasional immediate time-out expiration issues I see on the
    Pine64 board. The root cause of this needs to be investigated, but this
    fix looks like the right thing anyway.
