      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.
