  • 24e33164c   MA-14120 Add config to guard append bootargs support ... Browse Code »

    Grant user the permission to change the bootargs can be very
    dangerous, so add config 'CONFIG_APPEND_BOOTARGS' to guard the
    bootargs appending feature.

    Test: bootargs can't be appended if "CONFIG_APPEND_BOOTARGS" is
    not set.

    Add fastboot commands "fastboot oem at-get-vboot-unlock-challenge"
    and "fastboot oem at-unlock-vboot" to support the authenticated
    unlock feature for Android Things devices. Use software random
    numbers generator to generate the 16 bytes random challenge, it
    should be replaced with hardware encrypted random generator when
    the TEE part is ready.

    Test: Generate unlock challenge by:
    ./avbtool make_atx_unlock_credential
    --output=atx_unlock_credential.bin
    --intermediate_key_certificate=atx_pik_certificate.bin
    --unlock_key_certificate=atx_puk_certificate.bin
    --challenge=my_generated_challenge.bin
    --unlock_key=testkey_atx_puk.pem
    validated the unlock credential successfully on imx7d_pico
    and AIY.

    The sunXi arm64 build has overflown, leading to the main U-boot binary

    With the changes to split SPL/TPL for the RK3368, I apparently missed
    some needed adjustments to the RK3188 Kconfig and rock_defconfig.

    This fixes build-issues for the rock board after applying the RK3368
    enablement (and SPL/TPL) set that resulted from TPL_SERIAL_SUPPORT,
    TPL_ROCKCHIP_BACK_TO_BROM and TPL_TINY_MEMSET being separate symbols
    now.

  • ab4458bdb   string: Provide a slimmed-down memset() ... Browse Code »

    Most of the time the optimised memset() is what we want. For extreme
    situations such as TPL it may be too large. For example on the 'rock'
    board, using a simple loop saves a useful 48 bytes. With gcc 4.9 and
    the rodata bug, this patch is enough to reduce the TPL image below the
    limit.

    So far CONFIG_MD5SUM would need to be set by a board's include file.
    Since the command is really generic, move it over to Kconfig to allow
    it to be defined by either a board's defconfig, menuconfig or some
    config snippet merged via mergeconfig.sh.

  • 91b86e215   lib: Enable private libgcc by default ... Browse Code »

    This patch decouples U-Boot binary from the toolchain on systems where
    private libgcc is available. Instead of pulling in functions provided
    by the libgcc from the toolchain, U-Boot will use it's own set of libgcc
    functions. These functions are usually imported from Linux kernel, which
    also uses it's own libgcc functions instead of the ones provided by the
    toolchain.

    This patch solves a rather common problem. The toolchain can usually
    generate code for many variants of target architecture and often even
    different endianness. The libgcc on the other hand is usually compiled
    for one particular configuration and the functions provided by it may
    or may not be suited for use in U-Boot. This can manifest in two ways,
    either the U-Boot fails to compile altogether and linker will complain
    or, in the much worse case, the resulting U-Boot will build, but will
    misbehave in very subtle and hard to debug ways.

  • 7d9cde103   lib/tiny-printf.c: Add tiny printf function for space limited environments ... Browse Code »

    This patch adds a small printf() version that supports all basic formats.
    Its intented to be used in U-Boot SPL versions on platforms with very
    limited internal RAM sizes.

    To enable it, just define CONFIG_USE_TINY_PRINTF in your defconfig. This
    will result in the SPL using this tiny function and the main U-Boot
    still using the full-blown printf() function.

    This code was copied from:
    http://www.sparetimelabs.com/printfrevisited
    With mostly only coding style related changes so that its checkpatch
    clean.

    The size reduction is about 2.5KiB. Here a comparison for the db-mv784mp-gp
    (Marvell AXP) SPL:

    Without this patch:
    58963 18536 1928 79427 13643 ./spl/u-boot-spl

    With this patch:
    56542 18536 1956 77034 12cea ./spl/u-boot-spl

    Note:
    To make it possible to compile tiny-printf.c instead of vsprintf.c when
    CONFIG_USE_TINY_PRINTF is defined, the functions printf() and vprintf() are
    moved from common/console.c into vsprintf.c in this patch.

  • 027b728d4   Add support for LZ4 decompression algorithm ... Browse Code »

    This patch adds support for LZ4-compressed FIT image contents. This
    algorithm has a slightly worse compression ration than LZO while being
    nearly twice as fast to decompress. When loading images from a fast
    storage medium this usually results in a boot time win.

    Sandbox-tested only since I don't have a U-Boot development system set
    up right now. The code was imported unchanged from coreboot where it's
    proven to work, though. I'm mostly interested in getting this recognized
    by mkImage for use in a downstream project.
