      flash: complete CONFIG_SYS_NO_FLASH move with renaming · e856bdcf
      Masahiro Yamada authored
      We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is
      not completed. Finish this work by the tool.
      
      During this move, let's rename it to CONFIG_MTD_NOR_FLASH.
      Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH"
      than those of "#ifdef CONFIG_SYS_NO_FLASH".  Flipping the logic will
      make the code more readable.  Besides, negative meaning symbols do
      not fit in obj-$(CONFIG_...) style Makefiles.
      
      This commit was created as follows:
      
      [1] Edit "default n" to "default y" in the config entry in
          common/Kconfig.
      
      [2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH"
      
      [3] Rename the instances in defconfigs by the following:
        find . -path './configs/*_defconfig' | xargs sed -i \
        -e '/CONFIG_SYS_NO_FLASH=y/d' \
        -e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/'
      
      [4] Change the conditionals by the following:
        find . -name '*.[ch]' | xargs sed -i \
        -e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \
        -e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \
        -e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \
        -e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/'
      
      [5] Modify the following manually
        - Rename the rest of instances
        - Remove the description from README
        - Create the new Kconfig entry in drivers/mtd/Kconfig
        - Remove the old Kconfig entry from common/Kconfig
        - Remove the garbage comments from include/configs/*.h

      dm: select CONFIG_DM* options · 58d423b8
      Masahiro Yamada authored
      As mentioned in the previous commit, adding default values in each
      Kconfig causes problems because it does not co-exist with the
      "depends on" syntax.  (Please note this is not a bug of Kconfig.)
      We should not do so unless we have a special reason.  Actually,
      for CONFIG_DM*, we have no good reason to do so.
      
      Generally, CONFIG_DM is not a user-configurable option.  Once we
      convert a driver into Driver Model, the board only works with Driver
      Model, i.e. CONFIG_DM must be always enabled for that board.
      So, using "select DM" is more suitable rather than allowing users to
      modify it.  Another good thing is, Kconfig warns unmet dependencies
      for "select" syntax, so we easily notice bugs.
      
      Actually, CONFIG_DM and other related options have been added
      without consistency: some into arch/*/Kconfig, some into
      board/*/Kconfig, and some into configs/*_defconfig.
      
      This commit prefers "select" and cleans up the following issues.
      
      [1] Never use "CONFIG_DM=n" in defconfig files
      
      It is really rare to add "CONFIG_FOO=n" to disable CONFIG options.
      It is more common to use "# CONFIG_FOO is not set".  But here, we
      do not even have to do it.
      Less than half of OMAP3 boards have been converted to Driver Model.
      Adding the default values to arch/arm/cpu/armv7/omap3/Kconfig is
      weird.  Instead, add "select DM" only to appropriate boards, which
      eventually eliminates "CONFIG_DM=n", etc.
      
      [2] Delete redundant CONFIGs
      
      Sandbox sets CONFIG_DM in arch/sandbox/Kconfig and defines it again
      in configs/sandbox_defconfig.
      Likewise, OMAP3 sets CONFIG_DM arch/arm/cpu/armv7/omap3/Kconfig and
      defines it also in omap3_beagle_defconfig and devkit8000_defconfig.

      fdt: Allow ft_board_setup() to report failure · e895a4b0
      Simon Glass authored
      This function can fail if the device tree runs out of space. Rather than
      silently booting with an incomplete device tree, allow the failure to be
      detected.
      
      Unfortunately this involves changing a lot of places in the code. I have
      not changed behvaiour to return an error where one is not currently
      returned, to avoid unexpected breakage.
      
      Eventually it would be nice to allow boards to register functions to be
      called to update the device tree. This would avoid all the many functions
      to do this. However it's not clear yet if this should be done using driver
      model or with a linker list. This work is left for later.

      MAINTAINERS: comment out blank M: field · 535aad29
      Masahiro Yamada authored
      Since commit ddaf5c8f
      (patman: RunPipe() should not pipe stdout/stderr unless asked),
      Patman spits lots of "Invalid MAINTAINERS address: '-'"
      error messages for patches with global changes.
      It takes too long for Patman to process them.
      
      Anyway, "M:    -" does not carry any important information.
      Rather, it is just like a place holder in case of assigning
      a new board maintainer.  Let's comment out.
      
      This commit can be reproduced by the following command:
      
      find . -name MAINTAINERS | xargs sed -i -e '/^M:[[:blank:]]*-$/s/^/#/'

      MAINTAINERS: comment out invalid maintainers · e5a504eb
      Masahiro Yamada authored
      The "S:    Orphan" in MAINTAINERS means that the maintainer in the
      "M:" field is unreachable (i.e. the email address is not working).
      (Refer to the definition of "Orphan" adopted in U-Boot
      in the log of commit 31f1b654,
      "boards.cfg: move boards with invalid emails to Orphan")
      
      For patch files adding global changes, scripts/get_maintainer.pl
      adds bunch of such invalid email addresses, which results in
      tons of annoying bounce emails.
      
      This commit can be reproduced by the following command:
      
      find . -name MAINTAINERS | xargs sed -i -e '
      /^M:[[:blank:]]/ {
            N
            /S:[[:blank:]]Orphan/s/^/#/
      }

      Add board MAINTAINERS files · 93d4334f
      Masahiro Yamada authored
      We have switched to Kconfig and the boards.cfg file is going to
      be removed. We have to retrieve the board status and maintainers
      information from it.
      
      The MAINTAINERS format as in Linux Kernel would be nice
      because we can crib the scripts/get_maintainer.pl script.
      
      After some discussion, we chose to put a MAINTAINERS file under each
      board directory, not the top-level one because we want to collect
      relevant information for a board into a single place.
      
      TODO:
      Modify get_maintainer.pl to scan multiple MAINTAINERS files.

      kconfig: add board Kconfig and defconfig files · dd84058d
      Masahiro Yamada authored
      This commit adds:
       - arch/${ARCH}/Kconfig
          provide a menu to select target boards
       - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
          set CONFIG macros to the appropriate values for each board
       - configs/${TARGET_BOARD}_defconfig
          default setting of each board
      
      (This commit was automatically generated by a conversion script
      based on boards.cfg)
      
      In Linux Kernel, defconfig files are located under
      arch/${ARCH}/configs/ directory.
      It works in Linux Kernel since ARCH is always given from the
      command line for cross compile.
      
      But in U-Boot, ARCH is not given from the command line.
      Which means we cannot know ARCH until the board configuration is done.
      That is why all the "*_defconfig" files should be gathered into a
      single directory ./configs/.

      ppc4xx: Remove 4xx NAND booting support · 345b77ba
      Stefan Roese authored
      As ppc4xx currently only supports the deprecated nand_spl infrastructure
      and nobody seems to have time / resources to port this over to the newer
      SPL infrastructure, lets remove NAND booting completely.
      
      This should not affect the "normal", non NAND-booting ppc4xx platforms
      that are currently supported.

      Consolidate bool type · 472d5460
      York Sun authored
      'bool' is defined in random places. This patch consolidates them into a
      single header file include/linux/types.h, using stdbool.h introduced in C99.
      
      All other #define, typedef and enum are removed. They are all consistent with
      true = 1, false = 0.
      
      Replace FALSE, False with false. Replace TRUE, True with true.
      Skip *.py, *.php, lib/* files.

      Replace __bss_end__ with __bss_end · 3929fb0a
      Simon Glass authored
      Note this is a tree-wide change affecting multiple architectures.
      
      At present we use __bss_start, but mostly __bss_end__. This seems
      inconsistent and in a number of places __bss_end is used instead.
      
      Change to use __bss_end for the BSS end symbol throughout U-Boot. This
      makes it possible to use the asm-generic/sections.h file on all
      archs.
