  - Drop CONFIG_BUILD_MODE

+config UBOOTVERSION

+
+config SUBIMAGES
+	string "Subimages"
+	help
+	  This option allows you to specify the additional images.
+	  The main purpose is to enable what we called SPL/TPL.
+	  But we can specify them more genericlly in the form of
+	  "img1_output_dir:img1_defconfig,img2_output_dir:img2_defconfig".
+
+config SPL
+	bool "Enable SPL"
+	help
+	  If you want to build SPL as well as the normal image, say Y.
+	  This option is available for a while for the backward compatibility.
+	  We should use CONFIG_SUBIMAGES to specify the additional images.
+	  After switching to the generic sub-images framework, this option
+	  should be removed.
+
+config TPL
+	bool "Enable TPL"
+	depends on SPL
+	help
+	  If you want to build TPL as well as the normal image and SPL, say Y.
+	  This option is available for a while for the backward compatibility.
+	  We should use CONFIG_SUBIMAGES to specify the additional images.
+	  After switching to the generic sub-images framework, this option
+	  should be removed.
+
+config SPL_BUILD
+	bool "SPL Build"
+	select SPL
+	help
+	  This option selects the build mode.
+	  If you want to build this image as SPL, say Y.
+	  This option should be removed in future because
+	  we do not want to treat SPL/TPL as special cases.
+
+config TPL_BUILD
+	bool "TPL Build"
+	depends on SPL_BUILD
+	select TPL
+	help
+	  This option selects the build mode.
+	  If you want to build this image as TPL, say Y.
+	  This option should be removed in future because
+	  we do not want to treat SPL/TPL as special cases.
+
+config SYS_EXTRA_OPTIONS
+	string "Extra Options"
+	help
+	  The old configuration infrastructure (= mkconfig + boards.cfg)
+	  provided the extra options field. It you have something like
+	  "HAS_BAR,BAZ=64", the optional options
+	    #define CONFIG_HAS
+	    #define CONFIG_BAZ	64
+	  will be defined in include/config.h.
+	  This option was prepared for the smooth migration from the old
+	  configuration to Kconfig. Since this option will be removed sometime,
+	  new boards should not use this option.
