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".
