  • 43b6e38b2   dts: add property removal option CONFIG_OF_REMOVE_PROPS ... Browse Code »

    This can be used for device tree size reduction similar as
    CONFIG_OF_SPL_REMOVE_PROPS option. Some boards must pass the
    built-in DTB unchanged to the kernel, thus we may not cut it
    down unconditionally. Therefore enable the property removal
    list option only if CONFIG_OF_DTB_PROPS_REMOVE is selected.

    Add support for loading U-Boot on the Broadcom 7445 SoC. This port
    assumes Broadcom's BOLT bootloader is acting as the second stage
    bootloader, and U-Boot is acting as the third stage bootloader, loaded
    as an ELF program by BOLT.

  • d6a0c78a4   pylibfdt: compile pylibfdt only when dtoc/binman is necessary ... Browse Code »

    Currently, pylibfdt is always compiled if swig is installed on your
    machine. It is really annoying because most of targets (excepts
    x86, sunxi, rockchip) do not use dtoc or binman.

    "checkbinman" and "checkdtoc" are wrong. It is odd that the final
    build stage checks if we have built necessary tools. If your platform
    depends on dtoc/binman, you must be able to build pylibfdt. If swig
    is not installed, it should fail immediately.

    I added PYLIBFDT, DTOC, BINMAN entries to Kconfig. They should be
    property select:ed by platforms that need them. Kbuild will descend
    into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled.

    u-boot can be embedded within a FIT image with multiple DTBs. It then
    selects at run-time which one is best suited for the platform.
    Use the same principle here for the SPL: put the DTBs in a FIT image,
    compress it (LZO, GZIP, or no compression) and append it at the end of the
    SPL.

  • f291ce129   spl: dm: Kconfig: split OF_CONTROL and OF_PLATDATA between SPL and TPL ... Browse Code »

    For the RK3368, we want to use OF_PLATDATA in TPL, but full OF_CONTROL
    in SPL: this requires the introduction of a new family of
    configuration options to decouple SPL_OF_CONTROL and SPL_OF_PLATDATA
    from TPL.

    Consequently, Makefile.spl needs to be adjusted to test for these
    configuration items through the $(SPL_TPL_) macro instead of
    hard-coding the SPL variant.

  • 82f766d1d   Allow boards to initialize the DT at runtime. ... Browse Code »

    In some boards like the Raspberry Pi the initial bootloader will pass
    a DT to the kernel. When using U-Boot as such kernel, the board code in
    U-Boot should be able to provide U-Boot with this, already assembled
    device tree blob.

    This patch introduces a new config option CONFIG_OF_BOARD to use instead
    of CONFIG_OF_EMBED or CONFIG_OF_SEPARATE which will initialize the DT
    from a board-specific funtion instead of bundling one with U-Boot or as
    a separated file. This allows boards like the Raspberry Pi to reuse the
    device tree passed from the bootcode.bin and start.elf firmware
    files, including the run-time selected device tree overlays.

  • 2a792753d   dm: Add callback to modify the device tree ... Browse Code »

    Certain boards come in different variations by way of utilizing daughter
    boards, for example. These boards might contain additional chips, which
    are added to the main board's busses, e.g. I2C.

    The device tree support for such boards would either, quite naturally,
    employ the overlay mechanism to add such chips to the tree, or would use
    one large default device tree, and delete the devices that are actually
    not present.

    Regardless of approach, even on the U-Boot level, a modification of the
    device tree is a prerequisite to have such modular families of boards
    supported properly.

    Therefore, we add an option to make the U-Boot device tree (the actual
    copy later used by the driver model) writeable, and add a callback
    method that allows boards to modify the device tree at an early stage,
    at which, hopefully, also the application of device tree overlays will
    be possible.

    If it is empty u-boot.img is created without FDT partition:
    For example:

    0x8000000 -e 0 -n "U-Boot 2016.05-rc3 ..." -E -b -d u-boot-nodtb.bin u-boot.img
    Can't set 'timestamp' property for '' node (FDT_ERR_NOSPACE)
    FIT description: Firmware image with one or more FDT blobs

  • 5f3f7b79d   dts: keep clock-names and clocks in SPL DTB if SPL_CLK is enabled ... Browse Code »

    These two properties are necessary for SPL to get clocks from DT.

    Note:
    For now, only clock look-up by index is supported (clk_get_by_index()
    function), so "clock-names" is never parsed in U-Boot. However, we
    may want to support something like clk_get_by_name() in the future,
    so let's keep "clock-names" as well as "clocks".

    As we discussed a couple of times, negative CONFIG options make our
    life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ...
    and here is another one.

    Now, there are three boards enabling OF_CONTROL on SPL:
    - socfpga_arria5_defconfig
    - socfpga_cyclone5_defconfig
    - socfpga_socrates_defconfig

    This commit adds CONFIG_SPL_OF_CONTROL for them and deletes
    CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert
    the logic.
