    camera sometime can't been open once run M4 image.
    ISI-CH0 probe funtion is not called when meet issue.

    The root cause is:
    M4 image set assign resource SC_R_ISI_CH0 into m4 partition
    when open camera in m4 side.
    Uboot will call update_fdt_with_owned_resources to check
    the pd in current dts node. it will call sc_rm_is_resource_owned to
    check the pd whether in other partition, if yes, it will delete
    the dts node. uboot delete isi_0 node whose pd is SC_R_ISI_CH0.

    add CONFIG_SKIP_RESOURCE_CHECKING to skip checking resource when load
    dtb.

  • ed915f7d4   MA-14916-4 support dual bootloader for imx8m/imx8q ... Browse Code »

    This commit enables dual bootloader feature for imx8m/imx8q, but
    as commit 'a2018ab' already brings in some dual bootloader codes
    when enabling fastboot support, so this commit won't be a complete
    and standalone patch to introduce the dual bootloader feature.

    This commit will do the following:
    1. clean up dual bootloader flow and add missing implementation.
    2. Merge the dual bootloader entry for fit and container to one
    function 'mmc_load_image_raw_sector_dual_uboot'.

  • e00fcce4d   MLK-23110-1 usb: Decouple the CI_UDC DM gadget driver with EHCI MX6 driver ... Browse Code »

    On 2019.04 SPL, we enabled DM gadget driver for QM/QXP to support
    dual USB ports. The CI_UDC DM gadget driver will call init function
    inside EHCI mx6 driver, so when building SPL on iMX8QM/QXP with CI UDC
    enabled, we have to enable usb host driver as well, and this introduces
    about more than 40KB size to SPL.

    Move the common codes to a independent file, so that both host driver
    and gadget driver can call it, then decouple the host and gadget driver.

    Note: the patch only applies to ci_udc gadget DM driver. For non-DM gadget
    driver, it still depends ehci host interfaces.

  • 5ed2dc562   dtc: add ability to make nodes conditional on them being referenced ... Browse Code »

    This is needed when importing mainline DTs into U-Boot, as some started
    using this /omit-if-no-ref/ tag, so won't compile with U-Boot's current
    dtc copy. This is just a cherry-pick of the patch introducing this
    feature.
    Original commit message from Maxime:
    ------------------
    A number of platforms have a need to reduce the number of DT nodes,
    mostly because of two similar constraints: the size of the DT blob, and
    the time it takes to parse it.

    As the DT is used in more and more SoCs, and by more projects, some
    constraints start to appear in bootloaders running from SRAM with an
    order of magnitude of 10kB. A typical DT is in the same order of
    magnitude, so any effort to reduce the blob size is welcome in such an
    environment.

    Some platforms also want to reach very fast boot time, and the time it
    takes to parse a typical DT starts to be noticeable.

    Both of these issues can be mitigated by reducing the number of nodes in
    the DT. The biggest provider of nodes is usually the pin controller and
    its subnodes, usually one for each valid pin configuration in a given
    SoC.

    Obviously, a single, fixed, set of these nodes will be used by a given
    board, so we can introduce a node property that will tell the DT
    compiler to drop the nodes when they are not referenced in the tree, and
    as such wouldn't be useful in the targetted system.

    In upstream libfdt, 6dcb8ba4 "libfdt: Add helpers for accessing
    unaligned words" introduced changes to support unaligned reads for ARM
    platforms and 11738cf01f15 "libfdt: Don't use memcpy to handle unaligned
    reads on ARM" improved the performance of these helpers.

    In practice however, this only occurs when the user has forced the
    device tree to be placed in memory in a non-aligned way, which in turn
    violates both our rules and the Linux Kernel rules for how things must
    reside in memory to function.

    This "in practice" part is important as handling these other cases adds
    visible (1 second or more) delay to boot in what would be considered the
    fast path of the code.

  • c2a8b4f87   powerpc/mpc85xx: drop eSDHC periperhal clock code ... Browse Code »

    The below patch added eSDHC periperhal clock code initially.
    2d9ca2c mmc: fsl_esdhc: Add peripheral clock support

    The purpose was to fix up device tree properties "peripheral-frequency"
    so that linux could get the periperhal clock by it.
    However the implementation on both u-boot and linux was only
    for a Freescale SDK release. The linux part implementation had never
    been upstreamed. These code should not have been exist on u-boot
    mainline.

    Let's remove the powerpc part changes but keep the changes in
    fsl_esdhc driver. The changes in fsl_esdhc driver could be utilized
    to support SD UHS and eMMC HS200/HS400 speed modes for current
    Layerscape ARM platforms.

  • 1653b6a4b   fdt: Show the preprocessed .dts file on error ... Browse Code »

    When device-tree compilation fails it is sometimes tricky to see which
    line is broken, since the input file to dtc is a pre-processed version
    of the device tree.

    Add a line that points to the file that needs to be checked:

    When the error is in the main .dts file, output is something like this:

    output: 'Error: arch/x86/dts/.chromebook_coral.dtb.pre.tmp:478.46-47
    syntax error
    FATAL ERROR: Unable to parse input tree

    but in fact looking at that file shows nothing useful:

    PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_157, UP_20K, DEEP, NF1, HIZCRX1, DISPUPD)

    Instead we need to look at the preprocessed file, which shows:

    163 ((1U << 30) | (1 << 10)) ((0xb << 10) | PAD_CFG1_IOSSTATE_HIZCRX1)

    Here it is clear that PAD_CFG1_IOSSTATE_HIZCRX1 is not defined and so is
    not being resolved by the preprocessor.

    This commit adds an additional useful message:

    Check arch/x86/dts/.chromebook_coral.dtb.dts.tmp for errors

    Note that if the error is reported in an included file, such as
    u-boot.dtsi then the output is the following:

    Error: arch/x86/dts/u-boot.dtsi:137.14-15 syntax error
    FATAL ERROR: Unable to parse input tree

    But again, if the error is due to a preprocessor failure, like this:

    filename = CONFIG_IFW_INPUT_FILE;

    then you can't tell what the problem is by looking at the source. All you
    see is the original code:

    intel-ifwi {
    filename = CONFIG_IFW_INPUT_FILE;
    ...
    };
    };
    intel-fsp-m {
    filename = CONFIG_FSP_FILE_M;
    };

    Everything looks fine. But looking at the output of the preprocessor:

    intel-ifwi {
    filename = CONFIG_IFW_INPUT_FILE;
    ...
    };
    intel-fsp-m {
    filename = "fsp_m.bin";
    };

    This shows that the filename (normally "fitimage.bin") has not been
    inserted the preprocess, leading to the realisation that the value should
    be CONFIG_IFWI_INPUT_FILE.

    If the above does not make sense, I encourage people to try introducing
    errors in the device tree preprocessed values.
