kconfig: switch to Kconfig
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.
