[U-Boot] [PATCH v6 02/15] Do not apply: tools: add genkconfig

[Masahiro Yamada]

 ========================================
 Do not apply this patch to the main line
 ========================================

 What is this tool?
 ------------------

This tool converts boards.cfg to defconfig and Kconfig files.

It automatically generates
 - arch/${ARCH}/Kconfig
 - board/${VENDOR}/${BOARD}/Kconfig
 - board/${BOARD}/Kconfig
 - configs/${TARGET_BOARD}_defconfig

 How to use?
 -----------

Open tools/print_allconfigs with an editor.

Adjust cross compilers part for your environment.

  # Specify your favoriate cross tools
  CROSS_COMPILE_ARC=arc-linux-
  CROSS_COMPILE_AARCH64=aarch64-linux-gnu-
  CROSS_COMPILE_ARM=arm-unknown-linux-gnueabi-
   [snip]
  CROSS_COMPILE_X86=i386-linux-

And then, run "tools/genkconfig".

 Why is this patch here?
 -----------------------

The file boards.cfg is touched very frequently.
All the time, new/old boards are being added/removed.

The next commit was generated based on the u-boot/master at the time
I posted it.
It will become out-dated soon.

You can update it with this tool.

Changes in v6: None
Changes in v5:
 - Add CPU select menu for PowerPC

Changes in v4:
 - Remove debug code
 - Do not specify CONFIG_SYS_CPU if the cpu field of boards.cfg is '-'
 - Adjust to the current boards.cfg fields spec.
 - Add "select CPU" to PowerPC Kconfig
 - Generate only one defconfig per board

Changes in v3:
 - Create SPL defconfig into configs/<board>_spl_defconfig
   instead of conigs/spl/<board>_defconfig. Like the same for TPL.
   Because I want to handle Falcon boot more genericlly.
   If you build only configs/<board>_spl_defconfig, it is Falcon boot.
 - Create board select menu based on the 8th field of boards.cfg.
   It is common that many entries (= 7th field) share the same
   config header. So this change help to reduce the code redandancy.

Changes in v2:
 - Do not output CONFIG_BOARD_MAINTAINERS and CONFIG_BOARD_STATUS
 - Delete board/Kconfig and move "source board/*/*/Kconfig"
   statements to arch/*/Kconfig.
