  • c71630838   kbuild: move spl/Makefile to scripts/Makefile.spl ... Browse Code »

    All files under spl/ and tpl/ are generated during the build process
    except spl/Makefile.

    We can simplify clean-rule and git-ignore by moving spl/Makefile
    to somewhere else.

  • 63b4b5bae   fdt: Add DEV_TREE_BIN option to specify a device tree binary file ... Browse Code »
    46

    In some cases, an externally-built device tree binary is required to be
    attached to U-Boot. An example is when using image signing, since in that
    case the .dtb file must include the public keys.

    Add a DEV_TREE_BIN option to the Makefile, and update the documentation.

    Usage is something like:

    make DEV_TREE_BIN=boot/am335x-boneblack-pubkey.dtb

  • 89742924c   Check that u-boot.bin size looks correct ... Browse Code »

    Check that the image size matches the size we get from u-boot.bin. If it
    doesn't, that generally means that some extra sections are being added to
    u-boot.bin, meaning that it is not possible to access data appended to
    the U-Boot binary. This is used for device tree, so needs to work.

    This problem was introduced by commit b02bfc4. By adding a test we can
    prevent a reccurence.

  • 9262233a9   Makefile: fix clang warnings due to clang support ... Browse Code »

    Building u-boot tools with clang as a host compiler e.g. on
    FreeBSD with `gmake HOSTCC=clang CONFIG_USE_PRIVATE_LIBGCC=y tools`
    leads to many warnings [1] for every compiler invocation since
    commit 598e2d33. Part of mentioned commit imports linux patches:

    - kbuild: LLVMLinux: Adapt warnings for compilation with clang
    - kbuild: LLVMLinux: Add Kbuild support for building kernel with Clang

    No version of clang supports the gcc fno-delete-null-pointer-checks
    though, but it is only passed to clang. Gcc does not have the clang
    specific Qunused-arguments for the target. Furthermore several
    warnings are disabled which aren't encountered in u-boot. Since such
    a build has worked for quite some time and works after removing these
    changes, just remove the clang specific handling to restore normal
    building with clang as hostcc.

    [1] Actual warnings
    -------------------
    GEN include/autoconf.mk.dep
    arm-freebsd-gcc: unrecognized option '-Qunused-arguments'

    HOSTCC scripts/basic/fixdep
    clang: warning: argument unused during compilation:
    '-fno-delete-null-pointer-checks'

  • 2405d09c4   build: support a new image u-boot-dtb.img ... Browse Code »

    In SPL framework, SPL uses u-boot.img to load u-boot.bin.
    Here,
    u-boot.img = uImage header + u-boot.bin

    To use OF control with a separate devicetree,
    u-boot.dtb must be placed right after u-boot.bin.
    In this case, u-boot-dtb.bin is generally used.
    Here,
    u-boot-dtb.bin = u-boot.bin + u-boot.dtb

    We need u-boot-dtb.img to use both SPL framework
    and separate OF control at the same time.
    u-boot-dtb.img = uImage header + u-boot-dtb.bin

    For example, Zynq boards already define all of
    - CONFIG_SPL
    - CONFIG_OF_CONTROL
    - CONFIG_OF_SEPARATE

    So, the support of u-boot-dtb.img is urgent.

    cam_enc_4xx: convert to CONFIG_SPL_MAX_FOOTPRINT

    replaced CONFIG_SPL_MAX_SIZE by CONFIG_SPL_MAX_FOOTPRINT. However,
    CONFIG_SPL_MAX_SIZE is used in the Makefile for padding the SPL
    when preparing an u-boot.ais image. By removing CONFIG_SPL_MAX_SIZE
    said commits broke the ais image of the da850evm and cam_enc_4xx
    configurations.

    This patch converts the u-boot.ais target to use CONFIG_SPL_PAD_TO
    instead of CONFIG_SPL_MAX_SIZE for padding the SPL and adds
    a #define CONFIG_SPL_PAD_TO where it is required.

  • 65bb6d8de   kbuild: build with -Werror=date-time if the compiler supports it ... Browse Code »

    Using __DATE__, __TIME__ would make the build non-deterministic.

    If the code needs to refer to build date/time, use U_BOOT_DATE and
    U_BOOT_TIME in include/generated/timestamp_autogenerated.h instead.

    This commit has been imported from Linux Kernel,
    which should be applied to U-Boot too:

    commit fe7c36c7bde12190341722af69358e42171162f3
    Author: Josh Triplett
    Date: Mon Dec 23 13:56:06 2013 -0800

    Makefile: Build with -Werror=date-time if the compiler supports it

    GCC 4.9 and newer have a new warning -Wdate-time, which warns on any use
    of __DATE__, __TIME__, or __TIMESTAMP__, which would make the build
    non-deterministic. Now that the kernel does not use any of those
    macros, turn on -Werror=date-time if available, to keep it that way.

    The kernel already (optionally) records this information at build time
    in a single place; other kernel code should not duplicate that.

  • 794d5f554   Revert "build: Use filechk rules to create and update u-boot.lds" ... Browse Code »

    This reverts commit a8b993eb81c142a439c24b871a2317f765fe5397.

    Commit a8b993eb claims it fixes u-boot.lds rule by replacing
    $(call if_changed) with $(call filechk).

    But the problem had already been fixed by commit 395e60cd
    a few days before commit a8b993eb was posted.

    There is no reason to apply commit a8b993eb. What is worse is
    $(call filechk) is too strong to fix the problem and looks weird.

    Date of the two patches:

    [1] commit 395e60cdc292dc0183c6867d34b43f14a373df55

    Commit: Tom Rini
    CommitDate: Fri Apr 11 10:08:42 2014 -0400
    replaces $(call if_changed) -> $(call if_changed_dep)

    Commit: Tom Rini
    CommitDate: Fri Apr 18 16:14:16 2014 -0400
    replaces $(call if_changed) -> $(call filechk)

    A conflict must have happened when applying [2], but somehow it was
    applied, sadly.

    230

    Prior to this patch, the top-level linker script u-boot.lds
    used a simple $(call if_changed) check when generated.
    That mechanism misses cases where a possible include file
    change induces a change in the u-boot.lds too.

    This patch converts it to a stronger check using ($call filechk)
    that will also notice differences in file contents and
    will catch changes due to pre-processing as well.

    For instance,

    ... modify include/configs/tricoder.h
    $ make

    spl/u-boot-spl.lds should be updated in this case, but it wasn't.

    To fix this problem, linker scripts generation should be handled
    by $(call if_changed_dep,...) rather than by $(call if_changed,...).

  • 1a9df13d5   arm: mxs: Add support for generating signed BootStream ... Browse Code »

    This patch adds the groundwork for generating signed BootStream, which
    can be used by the HAB library in i.MX28. We are adding a new target,
    u-boot-signed.sb , since the process for generating regular non-signed
    BootStream is much easier. Moreover, the signed bootstream depends on
    external _proprietary_ _binary-only_ tool from Freescale called 'cst',
    which is available only under NDA.

    To make things even uglier, the CST or HAB mandates a kind-of circular
    dependency. The problem is, unlike the regular IVT, which is generated
    by mxsimage, the IVT for signed boot must be generated by hand here due
    to special demands of the CST. The U-Boot binary (or SPL binary) and IVT
    are then signed by the CST as a one block. But here is the problem. The
    size of the entire image (U-Boot, IVT, CST blocks) must be appended at
    the end of IVT. But the size of the entire image is not known until the
    CST has finished signing the U-Boot and IVT. We solve this by expecting
    the CST block to be always 3904B (which it is in case two files, U-Boot
    and the hand-made IVT, are signed in the CST block).
