[U-Boot] [RFC PATCH 02/17] kconfig: add basic Kconfig files

Masahiro Yamada yamada.m at jp.panasonic.com
Mon Mar 17 09:52:57 CET 2014 

We want to start with a basic set of CONFIG macros:

 - CONFIG_SPL, CONFIG_TPL
    Enable to support SPL/TPL image

 - CONFIG_SPL_BUILD, CONFIG_TPL_BUILD
    CONFIG_SPL_BUILD is set when building SPL/TPL.
    CONFIG_TPL_BUILD is set when building TPL.
    These macros are automatically set and cannot be changed.

 - Architecture select, CONFIG_ARM, CONFIG_PPC, CONFIG_X86, etc.

 - CPU select
    Some architectures support various CPU families.
    For ex. PowerPC can choose CPU family from
    CONFIG_74xx_7xx, CONFIG_MPC512X, CONFIG_5xx, etc.

 - Some macros to keep compatibility
    CONFIG_SYS_ARCH, CONFIG_SYS_CPU, CONFIG_SYS_SOC, CONFIG_SYS_BOARD,
    CONFIG_SYS_VENDOR should be moved to Kconfig from include/config.h.
    They corresponds to the fields of boards.cfg.
    CONFIG_SYS_CONFIG_NAME and CONFIG_SYS_EXTRA_OPTIONS correspond
    to "Options" fields of boards.cfg.

    Please note they can be set to different values
    between the main image and SPL.
    Tegra SoCs have CONFIG_SYS_CPU="armv7" for U-Boot main
    whereas CONFIG_SYS_CPU="arm720t" for SPL.

 - Misc
    Some macros just for record. Not used during build.
    CONFIG_BOARD_MAINTAINER corresponds to the last field of boards.cfg.
    CONFIG_ORPHAN_BOARD corresponds to the first field, "Active/Orphan".
