  • e14ba8a57   arch: Add explicit linker script for u-boot-elf ... Browse Code »

    Commit f4dc714aaa2d ("arm64: Turn u-boot.bin back into an ELF file after
    relocate-rela")
    introduce REMAKE_ELF option to recreate u-boot.elf from u-boot ->
    u-boot.bin + DT -> u-boot.elf.

    The best is to ilustrate it from make V=1 output
    cat u-boot-nodtb.bin dts/dt.dtb > u-boot-dtb.bin
    cp u-boot-dtb.bin u-boot.bin
    aarch64-linux-gnu-objcopy -I binary -B aarch64 -O elf64-littleaarch64 u-boot.bin u-boot-elf.o
    aarch64-linux-gnu-ld.bfd u-boot-elf.o -o u-boot.elf --defsym="_start"=0x8000000 -Ttext=0x8000000

    Last command has no explicit linker script passed that's why toolchain
    internal linker script is used.
    In Binutils 2.32 case it contains SIZEOF_HEADERS symbol which has changed
    behavior by commit
    https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=64029e93683a266c38d19789e780f3748bd6a188
    which result in situation that program headers has changed from
    (xilinx_zynqmp_mini_defconfig)

    Program Headers:
    Type Offset VirtAddr PhysAddr
    FileSiz MemSiz Flags Align
    LOAD 0x0000000000010000 0x00000000fffc0000 0x00000000fffc0000
    0x0000000000018918 0x0000000000018918 RW 0x10000

    Program Headers:
    Type Offset VirtAddr PhysAddr
    FileSiz MemSiz Flags Align
    LOAD 0x0000000000000000 0x00000000fffb0000 0x00000000fffb0000
    0x0000000000028918 0x0000000000028918 RW 0x10000

    Xilinx tools like XSDB or Bootgen are using program headers for loading ELF
    to the right location and by above binutils change ELF is loaded to
    incorrect location.

    The patch is explicitly use u-boot-elf.lds (just cat now) for u-boot.elf
    recreation which is called when REMAKE_ELF is setup.
    By purpose u-boot-elf.lds doesn't contain OUTPUT_FORMAT/OUTPUT_ARCH to be
    able to use by all archs.

  • 48313fe51   sunxi: Move common defconfig options to Kconfig ... Browse Code »

    Some config symbols are found in *almost* every _defconfig file for
    Allwinner boards, because those options are actually a platform choice,
    and not a per-board decision.
    Some of these options are older, some have recently been added.

    Move those options to be set for all Allwinner boards in their
    respective Kconfig files.

    The rationales are as follows:
    - NR_DRAM_BANKS: All Allwinner SoC map DRAM at one contiguous region of
    address space only, starting at 1 GB. So it's always one bank.
    - SPL_{DOS,EFI}_PARTITION: The Allwinner SPL does only support raw MMC
    accesses, we don't care about filesystems or partitions in there, so
    there is no need to define those symbols at all.
    - USE_PREBOOT: We start USB early when a keyboard is configured, using the
    preboot env variable, so we need to set this variable.
    - SYS_RELOC_GD_ENV_ADDR: We don't specify any ENV_ADDR, so need this
    symbol to be set (according to 8d8ee47e03e).
    - SYS_USB_EVENT_POLL_VIA_INT_QUEUE: According to commit eab9433aa55428,
    specifying this reduces the latency of the USB keyboard handling, so
    this was formerly enabled in config headers for all Allwinner boards.

    doc/uImage.FIT/overlay-fdt-boot.txt is describing how to create FIT
    image with DT overlays in it.
    Add support for this feature to SPL.

    Here is the ZynqMP fragment where dtb points to full DT and dtbo is
    overlay which should be applied on the top of dtb.
    config {
    description = "ATF with full u-boot overlay";
    firmware = "atf";
    loadables = "uboot";
    fdt = "dtb", "dtbo";
    };

    The whole feature depends on OF_LIBFDT_OVERLAY which is adding +4kB code
    and 0 for platforms which are not enabling this feature.

    For all the Rockchip SoCs with SPL_LOAD_FIT enable, we need to build

    All the Rockchip boards with SPL_LOAD_FIT now supports FIT generator to
    get ATF/OPTEE binary path from environment and pass the build even if no
    ATF/OPTEE binary exist, so we can enable this feature for the rockchip

  • 93db2b83e   Kconfig add config ERR_PTR_OFFSET ... Browse Code »

    Some U-Boot pointers have redundant information, so we can use a scheme
    where we can return either an error code or a pointer with the same
    return value. The default implementation just casts the pointer to a
    number, however, this may fail on platforms where the end of the address
    range is used for valid pointers (e.g. 0xffffff00 is a valid heap pointer
    in socfpga SPL). For such platforms, this value provides an upper range
    of those error pointer values - up to 'MAX_ERRNO' bytes below this value
    must be unused/invalid addresses.

    Commit 3a7c45f6a772 ("simple-bus: add DM_FLAG_PRE_RELOC flag to
    simple-bus driver") causes some i.MX boards that were converted
    to DM, such as warp7, to fail to boot.

    As explained by Lukas Auer:

    "With the patch, U-Boot probes the drivers for devices under simple-bus
    device tree nodes in the pre-relocation device model. The default value
    of CONFIG_SYS_MALLOC_F_LEN (0x400) leaves U-Boot with not enough memory to
    do this, causing it to hang."

    Fix this problem by providing a convenient default value for
    CONFIG_SYS_MALLOC_F_LEN.

  • 5602330df   ARM: rmobile: Add recovery SPL for R-Car Gen3 ... Browse Code »

    Build an SPL which can be started via SCIF download mode on R-Car Gen3
    and allows loading and executing U-Boot uImage with the next stage code.
    This is also useful for starting e.g. ATF BL2, which inits the hardware
    and returns to the U-Boot SPL, which can then load e.g. U-Boot proper.

    The H3, M3-W, M3-N SoCs have plenty of SRAM for storing the U-Boot SPL
    while the payload, e.g. ATF BL2, executes, so there is no problem here.

    However, E3 and D3 have much less SRAM, hence the loader uses a trick
    where it copies itself beyond the area used by BL2 and executes from
    there. That area is 32kiB large and not enough to hold U-Boot SPL, BSS,
    stack and malloc area, so the later two are placed at +0x4000 offset
    from start of SRAM, another area not used by ATF BL2. To make things
    even more complicated, the SCIF loader cannot load to the upper 32kiB
    of the SRAM directly, hence the copying approach.

    CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ.

    To do this
    * replace all occurrences of CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ
    * set CONFIG_SYS_CLK_FREQ to the old value of CONFIG_83XX_CLKIN in all
    MPC83xx config files

    This patch adds the CONFIG_SPL_IMAGE option to select the SPL image that

    This patch also sets CONFIG_SPL_IMAGE to "spl/boot.bin" for AT91 targets
    which use SPL NAND support (boot from NAND). For these build targets the
    combined image "u-boot-with-spl.bin" is now automatically generated and
    can be programmed into NAND as one single image (vs. SPL image and U-Boot
    as 2 separate images).
