      gitignore: remove stale /LOG pattern · 43c908aa
      Masahiro Yamada authored
      The /LOG directory was created by the old MAKEALL tool, which was
      deleted by commit c8a3777c ("Drop the MAKEALL tool").

      kconfig: re-sync with Linux 4.17-rc4 · e91610da
      Eugeniu Rosca authored
      Align Kconfig to Linux 4.17-rc4 with minimal impact on non-kconfig files.
      
      Previous Kconfig sync was done by commit bf7ab1e7 ("kconfig:
      re-sync with Linux 4.10") and it achieved almost perfect alignment with
      a few (intended) exceptions, caused by below U-boot commits:
      
      [A] v2015.04 5f9eb220 ("kbuild: remove scripts/multiconfig.sh")
      [B] v2015.07 20c20826 ("Kconfig: Enable usage of escape char '\' in string values")
      [C] v2016.01 da58dec8 ("Various Makefiles: Add SPDX-License-Identifier tags")
      [D] v2016.03 5b8031cc ("Add more SPDX-License-Identifier tags")
      [E] v2016.03 192bc694 ("Fix GCC format-security errors and convert sprintfs.")
      
      Here is the list of Kconfig commits which followed the v4.10 alignment:
      
      [F] v2018.01 0931ed3c ("kconfig/symbol.c: use correct pointer type argument for sizeof")
      [G] v2018.03 1414e09b ("kconfig: revert change that was not needed for -Wformat-security")
      [H] v2018.05 83d290c5 ("SPDX: Convert all of our single license tags to Linux Kernel style")
      
      Commit [F] was subsequently applied to Linux kernel as commit [I]
      with the same patch id, so it won't contribute to further misalignment.
      
      [I] v4.15-rc1 88127dae6ed9 ("kconfig/symbol.c: use correct pointer type argument for sizeof")
      
      Commit [G] is a Kconfig-specific revert of commit [E].
      Commit [H] relocated and reformatted the license doing no functional change.
      
      In summary, the only functional change that makes U-boot Kconfig
      diverge from Linux Kconfig is commit [B]. After a brief analysis,
      the purpose of [B] seems to be placing "\n" literals in string symbols
      like CONFIG_AUTOBOOT_PROMPT="autoboot in %d seconds\n" in order to pass
      them directly to printf and expect correct output at runtime. Currently,
      Linux doesn't seem to have this requirement, so for the moment [B] looks
      like a U-boot specific feature/fix. From point of view of further Kconfig
      alignment and backporting efforts, it is highly desired that commits
      like [B] are propagated to Linux and any Kconfig fixes/features are
      contributed to Linux kernel first. This specific Kconfig re-sync just
      keeps [B] in place.
      
      Contrary to 4.10 Kconfig re-sync (which achieves zero non-kconfig
      changes), 4.17-rc4 re-sync does some amount of updates in Kbuild
      (striving to keep them at minimum), due to a number of reasons:
      * Kbuild is affected by the removal of Kconfig "*shipped" files and now
        requires flex and bison pre-installed on the host.
      * PYTHON{2,3} variables are defined in top-level Makefile as
        prerequisite for running the newly developed Kconfig unit tests.
      * silentoldconfig becomes an "internal implementation detail" deprecated
        for external use, being renamed to syncconfig.
      
      The exact non-kconfig files touched by this commit are:
      
      $ git show --format="" --stat -- ':!scripts/kconfig'
       .gitignore             |  2 ++
       Makefile               |  9 +++++++--
       scripts/Makefile.build | 11 +++++++++++
       scripts/Makefile.lib   | 41 ++++++++++++-----------------------------
      
      The imported Linux commits touching the above files are:
      
      c054be10ffdbd5   ("remove gperf left-overs from build system")
      73a4f6dbe70a1b   ("kbuild: add LEX and YACC variables")
      033dba2ec06c47   ("kbuild: prepare to remove C files pre-generated by flex and bison")
      eea199b445f64c   ("kbuild: remove unnecessary LEX_PREFIX and YACC_PREFIX")
      e71de5ee08dcb0   ("kbuild: remove remaining use of undefined YACC_PREFIX")
      d59fbbd09d5d6b   ("kbuild: replace hardcoded bison in cmd_bison_h with $(YACC)")
      911a91c39cabcb H ("kconfig: rename silentoldconfig to syncconfig")
      59889300274569   (".gitignore: move *.lex.c *.tab.[ch] patterns to the top-level .gitignore")
      9a8dfb394c0467   ("kbuild: clean up *.lex.c and *.tab.[ch] patterns from top-level Makefile")

      e9781b52d4e0e3 H ("kbuild: add PYTHON2 and PYTHON3 variables")
      
      The commits marked with 'H' are assessed as "hard" (build will fail)
      prerequisites and the rest of them are assessed as "soft" prerequisites
      for the re-sync. In spite of relatively high number of non-H commits,
      they belong to this Kconfig update topic-wise and decrease the number of
      cherry pick conflicts for many commits in this series. Additional effort
      can be put in eliminating the soft prerequisites, if really needed.
      
      The commits which contributed to this Kconfig re-sync are listed below.
      Whenever a conflict resolution has been performed (mostly by hand, but
      sometimes automatically by git), it is revealed by the '!' sign in the
      second column, which means a patch id mismatch between Linux and U-boot

      The current Kconfig update generates below build-time warnings:

      scripts/dtc/dtc-parser.y: warning: 3 shift/reduce conflicts [-Wconflicts-sr]
        YACC    scripts/dtc/dtc-parser.tab.c
      scripts/dtc/dtc-parser.y: warning: 3 shift/reduce conflicts [-Wconflicts-sr]
      
      This seems to happen because the Kbuild updates apparently didn't make
      room for both "*shipped"-based builds and flex/bison-based builds. A
      similar problem has been reported for genksyms parser in v4.17-rc1
      commit 833e622459432e ("genksyms: generate lexer and parser during build
      instead of shipping"). I have figured out empirically that the warnings
      are healed after updating the in-tree U-boot DTC to upstream v1.4.6-9,
      same as done by Linux v4.17-rc1 commit 9130ba88464032 ("scripts/dtc:
      Update to upstream version v1.4.6-9-gaadd0b65c987"). Whether fixing the
      DTC-related yacc warnings should be done together with the Kconfig
      re-sync, I would like to hear from community.
      
      My testing was limited to:
      - make defconfig all
      - make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu- r8a7795_ulcb_defconfig all
      - comparing .config before and after the re-sync
      - running the newly imported Kconfig unit tests as seen below:
      
      $ make testconfig

      kconfig: remove mkconfig and boards.cfg · a2580ebb
      Masahiro Yamada authored
      The old configuration script is no longer necessary.
      Nor is boards.cfg a primary database.
      We can generate it with the genboardscfg.py tool
      based on the latest Kconfig, defconfig and MAINTAINERS.

      kconfig: switch to Kconfig · 51148790
      Masahiro Yamada authored
      This commit enables Kconfig.
      Going forward, we use Kconfig for the board configuration.
      mkconfig will never be used. Nor will include/config.mk be generated.
      
      Kconfig must be adjusted for U-Boot because our situation is
      a little more complicated than Linux Kernel.
      We have to generate multiple boot images (Normal, SPL, TPL)
      from one source tree.
      Each image needs its own configuration input.
      
      Usage:
      
      Run "make <board>_defconfig" to do the board configuration.
      
      It will create the .config file and additionally spl/.config, tpl/.config
      if SPL, TPL is enabled, respectively.
      
      You can use "make config", "make menuconfig" etc. to create
      a new .config or modify the existing one.
      
      Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
      and do likewise for tpl/.config file.
      
      The generic syntax of configuration targets for SPL, TPL is:
      
        <target_image>/<config_command>
      
      Here, <target_image> is either 'spl' or 'tpl'
            <config_command> is 'config', 'menuconfig', 'xconfig', etc.
      
      When the configuration is done, run "make".
      (Or "make <board>_defconfig all" will do the configuration and build
      in one time.)
      
      For futher information of how Kconfig works in U-Boot,
      please read the comment block of scripts/multiconfig.py.
      
      By the way, there is another item worth remarking here:
      coexistence of Kconfig and board herder files.
      
      Prior to Kconfig, we used C headers to define a set of configs.
      
      We expect a very long term to migrate from C headers to Kconfig.
      Two different infractructure must coexist in the interim.
      
      In our former configuration scheme, include/autoconf.mk was generated
      for use in makefiles.
      It is still generated under include/, spl/include/, tpl/include/ directory
      for the Normal, SPL, TPL image, respectively.

      Trivial fix to .gitignore for spl/Makefile
      
      According to the gitignore man page:
      
      "An optional prefix "!" which negates the pattern; any matching file
      excluded by a previous pattern will become included again."
      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
      So the directory exclude "/spl/*" must come before the exception
      for spl/Makefile otherwise it has no effect.

      dts/Makefile: simplify dtc invocation · cc4f427b
      Stephen Warren authored
      The invocation of dtc is significantly more complex that it could be,
      in order to work around an issue on old versions of dtc, which print
      a message to stdout every time they run.
      
      Remove this workaround, on the assumption that people have or will
      upgrade to a newer version of dtc. This simplifies the build rule
      significantly.
      
      Related, split the invocation of cpp and dtc into separate commands
      rather than a pipeline, so that if either fail, it is detected. This has
      the nice benefit of saving off the result of the pre-processing step,
      allowing it to be easily inspected.
      
      Assuming a new enough dtc (which an earlier patch enforces), dtc will
      parse #line directives in its input file, and generate correct file and
      line numbers in error messages, even though cpp is unconditionally
      applied to its input file.

      arm: mxs: Preprocess u-boot.bd so they contain full path · 714dc001
      Marek Vasut authored
      The u-boot-imx23.bd and u-boot-imx28.bd need to be preprocessed, otherwise
      they have issues with out-of-tree build where elftosb tool couldn't sometimes
      find the u-boot.bin and spl/u-boot-spl.bin .
      
      Preprocess these .bd files with sed and insert full path to u-boot.bin and
      spl/u-boot-spl.bin to prevent this issue. Moreover, to avoid adding more
      churn into main Makefile, move all this preprocessing and u-boot.sb generation
      into CPU directory instead.
