      common: image: Add support for post-processing of images · eba3fbd6
      Andreas Dannenberg authored
      This commit allows injecting a board/platform/device-specific post-
      processing function into the FIT image data loading process, which can
      include modifying the size and altering the starting source address of
      an image data artifact. This might be desired to do things like strip
      headers or footers attached to the images before they were packaged into
      the FIT, or to perform operations such as decryption or authentication.
      Introduce new configuration option CONFIG_FIT_IMAGE_POST_PROCESS to
      allow controlling this feature. If enabled, a platform-specific post-
      process function must be provided.

      treewide: move CONFIG_PHYS_64BIT to Kconfig · bb6b142f
      Masahiro Yamada authored
      We need to ensure that CONFIG_PHYS_64BIT is configured via Kconfig so
      that it is always available to the build system.  Otherwise we can run
      into cases where we have inconsistent sizes of certain attributes.
      Ravi Babu reported offset mismatch of struct dwc3 across files since
      commit 95ebc253 ("types.h: move and redefine resource_size_t").
      Since the commit, resource_addr_t points to phys_addr_t, whose size
      is dependent on CONFIG_PHYS_64BIT for ARM architecture.
      I tried my best to use "select" where possible (for example, ARMv8
      architecture) because I think this kind of option is generally user-
      unconfigurable.  However, I see some of PowerPC boards have 36BIT
      defconfigs as well as 32BIT ones.  I moved CONFIG_PHYS_64BIT to the
      defconfigs for such boards.
      CONFIG_36BIT is no longer referenced, so all of the defines were
      removed from CONFIG_SYS_EXTRA_OPTIONS.
      Fixes: 95ebc253

      Kconfig: Add a new DISTRO_DEFAULTS Kconfig option · 9f823615
      Hans de Goede authored
      DISTRO_DEFAULTS is intended to mirror / replace
      The intend is for boards which include this file to select this from
      their Kconfig files and when moving setting to Kconfig which are #define-ed
      in config_distro_defaults.h to select this from DISTRO_DEFAULTS so that
      boards which have selected DISTRO_DEFAULTS will keep the same configuration
      as before without needing any defconfig file changes.
      The initial list of selected things matches all settings recently removed
      from config_distro_defaults.h because they have been converted to Kconfig,
      with the exception of CMD_ELF and CMD_NET, which have a default of y, if
      the default of these ever changes they should be selected by DISTRO_DEFAULTS
      For testing and example purposes this commit also converts ARCH_SUNXI
      to use DISTRO_DEFAULT instead of selecting everything it needs itself.

      spl: Add an option to load a FIT containing U-Boot · f1dcee59
      Simon Glass authored
      This provides a way to load a FIT containing U-Boot and a selection of device
      tree files. The board can select the correct device tree by probing the
      hardware. Then U-Boot is started with the selected device tree.

      Kconfig: Move CONFIG_FIT and related options to Kconfig · 73223f0e
      Simon Glass authored
      There are already two FIT options in Kconfig but the CONFIG options are
      still in the header files. We need to do a proper move to fix this.
      Move these options to Kconfig and tidy up board configuration:
      Unfortunately the first one is a little complicated. We need to make sure
      this option is not enabled in SPL by this change. Also this option is
      enabled automatically in the host builds by defining CONFIG_FIT in the
      image.h file. To solve this, add a new IMAGE_USE_FIT #define which can
      be used in files that are built on the host but must also build for U-Boot
      and SPL.
      Note: Masahiro's moveconfig.py script is amazing.

      Move all command code into its own directory · 72a8cf8d
      Simon Glass authored
      There are a lot of unrelated files in common, including all of the commands.
      Moving them into their own directory makes them easier to find and is more
      Some commands include non-command code, such as cmd_scsi.c. This should be
      sorted out at some point so that the function can be enabled with or without
      the associated command.
      Unfortunately, with m68k I get this error:
      m68k:  +   M5329AFEE
      +arch/m68k/cpu/mcf532x/start.o: In function `_start':

      I hope someone can shed some light on what this means. I hope it isn't
      depending on the position of code in the image.

      dm: spl: Support device tree when BSS is in a different section · 10172962
      Simon Glass authored
      At present in SPL we place the device tree immediately after BSS. This
      avoids needing to copy it out of the way before BSS can be used. However on
      some boards BSS is not placed with the image - e.g. it can be in RAM if
      Add an option to tell U-Boot that the device tree should be placed at the
      end of the image binary (_image_binary_end) instead of at the end of BSS.
      Note: A common reason to place BSS in RAM is to support the FAT filesystem.
      We should update the code so that it does not use so much BSS.

      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.
      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: 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
      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.
