      dlmalloc: do memset in malloc init as new default config · 0aa8a4ad
      Przemyslaw Marczak authored
      This commit introduces new config: CONFIG_SYS_MALLOC_CLEAR_ON_INIT.
      
      This config is an expert option and is enabled by default.
      
      The all amount of memory reserved for the malloc, is by default set
      to zero in mem_malloc_init(). When the malloc reserved memory exceeds
      few MiB, then the boot process can slow down.
      
      So disabling this config, is an expert option to reduce the boot time,
      and can be disabled by Kconfig.
      
      Note:
      After disable this option, only calloc() will return the pointer
      to the zeroed memory area. Previously, without this option,
      the memory pointed to untouched malloc memory region, was filled
      with zeros. So it means, that code with malloc() calls should
      be reexamined.

      kconfig: remove unneeded dependency on !SPL_BUILD · d648964f
      Masahiro Yamada authored
      Now CONFIG_SPL_BUILD is not defined in Kconfig, so
      "!depends on SPL_BUILD" and "if !SPL_BUILD" are redundant.

      kconfig: switch to single .config configuration · e02ee254
      Masahiro Yamada authored
      When Kconfig for U-boot was examined, one of the biggest issues was
      how to support multiple images (Normal, SPL, TPL).  There were
      actually two options, "single .config" and "multiple .config".
      After some discussions and thought experiments, I chose the latter,
      i.e. to create ".config", "spl/.config", "tpl/.config" for Normal,
      SPL, TPL, respectively.
      
      It is true that the "multiple .config" strategy provided us the
      maximum flexibility and helped to avoid duplicating CONFIGs among
      Normal, SPL, TPL, but I have noticed some fatal problems:
      
      [1] It is impossible to share CONFIG options across the images.
        If you change the configuration of Main image, you often have to
        adjust some SPL configurations correspondingly.  Currently, we
        cannot handle the dependencies between them.  It means one of the
        biggest advantages of Kconfig is lost.
      
      [2] It is too painful to change both ".config" and "spl/.config".
        Sunxi guys started to work around this problem by creating a new
        configuration target.  Commit cbdd9a97 (sunxi: kconfig: Add
        %_felconfig rule to enable FEL build of sunxi platforms.) added
        "make *_felconfig" to enable CONFIG_SPL_FEL on both images.
        Changing the configuration of multiple images in one command is a
        generic demand.  The current implementation cannot propose any
        good solution about this.
      
      [3] Kconfig files are getting ugly and difficult to understand.
        Commit b724bd7d (dm: Kconfig: Move CONFIG_SYS_MALLOC_F_LEN to
        Kconfig) has sprinkled "if !SPL_BUILD" over the Kconfig files.
      
      [4] The build system got more complicated than it should be.
        To adjust Linux-originated Kconfig to U-Boot, the helper script
        "scripts/multiconfig.sh" was introduced.  Writing a complicated
        text processor is a shell script sometimes caused problems.
      
      Now I believe the "single .config" will serve us better.  With it,
      all the problems above would go away.  Instead, we will have to add
      some CONFIG_SPL_* (and CONFIG_TPL_*) options such as CONFIG_SPL_DM,
      but we will not have much.  Anyway, this is what we do now in
      scripts/Makefile.spl.
      
      I admit my mistake with my apology and this commit switches to the
      single .config configuration.
      
      It is not so difficult to do that:
      
       - Remove unnecessary processings from scripts/multiconfig.sh
        This file will remain for a while to support the current defconfig
        format.  It will be removed after more cleanups are done.
      
       - Adjust some makefiles and Kconfigs
      
       - Add some entries to include/config_uncmd_spl.h and the new file
         scripts/Makefile.uncmd_spl.  Some CONFIG options that are not
         supported on SPL must be disabled because one .config is shared
         between SPL and U-Boot proper going forward.  I know this is not
         a beautiful solution and I think we can do better, but let's see
         how much we will have to describe them.
      
       - update doc/README.kconfig
      
      More cleaning up patches will follow this.

      kconfig: Adjust ordering so that defaults work as expected · 66afaef2
      Simon Glass authored
      At present defaults in arch-specific Kconfig files are ignored if the
      top-level item comes ahead of it in include order. This means that it is
      not possible to have a U-Boot default that architectures and boards can
      override. This does not seem very useful.
      
      Move the include earlier to support this.

      Kconfig: move CONFIG_SYS_CLK_FREQ to Kconfig · 33d88183
      Alexey Brodkin authored
      It makes sense to specify CONFIG_SYS_CLK_FREQ in "configs/xx_defconfig"
      instead of "include/configs/xxx.h" because then header will be reusable
      across boards with different CPU clocks.
      
      Also this nice to have an ability for end user to tune this value
      himself via "menuconfig".
      
      For now I'm only applying this change to all ARC configs because
      otherwise scope of change will be huge.
