  • 5fbed8f2c   ARM: Kconfig: Move TI_SECURE_DEVICE to a common area ... Browse Code »

    TI_SECURE_DEVICE is used by both OMAP2+ and Keystone2 family devices,
    and so when ARCH_OMAP2PLUS was used to gate off the OMAP2+ Kconfig
    Keystone2 family devices lost this config option.

    Move this option out of mach-omap2 Kconfig to a spot accessible by both
    families. We picked arch/arm/Kconfig over the TI specific board/ti/
    location as this option is not specific to our boards but rather our
    architecture.

    Plus at some point this option can be changed to just
    SECURE_DEVICE, as having secure parts is not exclusive to TI and
    so other vendors can interpret this option as needed by their device
    configurations.

    Fixes: a93fbf4a7892 ("ARM: omap2+: rename config to ARCH_OMAP2PLUS and consolidate Kconfig")

  • fef4a545b   arm: socfpga: use imply instead of select where applicable ... Browse Code »

    Kconfig should only 'select' features that are required for an arch.
    Standard features that can be disabled without breaking board support
    should use 'imply' instead, to allow users to disable it.

    These options are changed for mach-socfpga:
    - DM_SPI & DM_SPI_FLASH: only required with QSPI support enabled
    - SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION: the boot rom supports a
    partitionless mode also, where SPL is located at address 0
    - HW_WATCHDOG: while all mainline board defconfigs use it, U-Boot
    should still work without it.

    All Socfpga boards from ./include/configs/socfpga_* define

    To ease CONFIG_HW_WATCHDOG conversion to Kconfig select it in
    config ARCH_SOCFPGA (arch/arm/Kconfig) section.

  • ddcca7305   ARM: qemu-arm: Add support for AArch64 ... Browse Code »

    This adds support for '-machine virt' on AArch64. This is rather simple:
    we just add TARGET_QEMU_ARM_xxBIT to select a few different Kconfig
    symbols, provide the ARMv8 memory map from the board file and add a new
    defconfig based on the 32-bit defconfig.

  • 8163faf95   ARMv8: add optional Linux kernel image header ... Browse Code »
    12

    Allow placing a Linux kernel image header at the start of the U-Boot
    binary. This is useful since the image header reports the amount of memory
    (BSS and similar) that U-Boot needs to use, but that isn't part of the
    binary size. This can be used by the code that loads U-Boot into memory to
    determine where to load U-Boot, based on other users of memory.

  • e6c904489   ARMv8: Allow dynamic early stack pointer ... Browse Code »

    U-Boot typically uses a hard-coded value for the stack pointer before
    relocation. Implement option SYS_INIT_SP_BSS_OFFSET to instead calculate
    the initial SP at run-time. This is useful to avoid hard-coding addresses
    into U-Boot, so that can be loaded and executed at arbitrary addresses and
    thus avoid using arbitrary addresses at runtime. This option's value is
    the offset added to &_bss_start in order to calculate the stack pointer.
    This offset should be large enough so that the early malloc region, global
    data (gd), and early stack usage do not overlap any appended DTB.

  • ab0ab54e4   armv8: Implement workaround for Cortex-A53 erratum 855873 ... Browse Code »

    855873: An eviction might overtake a cache clean operation
    Workaround: The erratum can be avoided by upgrading cache clean by
    address operations to cache clean and invalidate operations. For
    Cortex-A53 r0p3 and later release, this can be achieved by setting
    CPUACTLR.ENDCCASCI to 1.

    This patch is to implement the workaround for this erratum.

  • 14ad6eb26   rockchip: enable boot0-hook for all Rockchip SoCs ... Browse Code »

    Rockchip SoCs bootrom design is like this:
    - First 2KB or 4KB internal memory is for bootrom stack and heap;
    - Then the first 4-byte suppose to be a TAG like 'RK33';
    - The the following memory address end with '0004' is the first
    instruction load and running by bootrom;

    Let's use the boot0 hook to reserve the first 4-byte tag for all
    the Rockchip SoCs.

  • 49e93875a   arm64: support running at addr other than linked to ... Browse Code »

    This is required in the case where U-Boot is typically loaded and run at
    a particular address, but for some reason the RAM at that location is not
    available, e.g. due to memory fragmentation loading other boot binaries or
    firmware, splitting an SMP complex between various different OSs without
    using e.g. the EL2 second-stage page tables to hide the memory asignments,
    or due to known ECC failures.

  • 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.

  • 07df697e1   mx25: Move MX25 selection to Kconfig ... Browse Code »

    The motivation for moving MX25 selection to Kconfig is to be
    able to better handle MX25 specific errata, so that an errata option
    can be selected at SoC level instead of board level.

    This selection method also aligns with the way other i.MX SoCs are
    selected in U-Boot.
