When I posted the RFC version of Kconfig series, I defined CONFIG_SYS_ARCH, CONFIG_SYS_CPU, CONFIG_SYS_SOC, CONFIG_SYS_VENDOR, CONFIG_SYS_BOARD in Kconfig.
For example, configs/harmony_defconfig was like this: CONFIG_SPL=y CONFIG_ARM=y CONFIG_SYS_CPU="armv7" CONFIG_SOC_DIR=y CONFIG_SYS_SOC="tegra20" CONFIG_SYS_BOARD="harmony" CONFIG_VENDOR_DIR=y CONFIG_SYS_VENDOR="nvidia" CONFIG_SYS_CONFIG_NAME="harmony" CONFIG_BOARD_MAINTAINER="Tom Warren <twar...@nvidia.com>" But the most reviewers involved did not like that. (See http://patchwork.ozlabs.org/patch/330915/) Instead, Daniel Schwierzeck suggested to select a board by using boolean macro: something like this, CONFIG_BOARD_HARMONY, CONFIG_VENDOR_NVIDIA, ... I agree this is a good idea. But string macros are used everywhere in U-Boot. $(CPU), $(SOC), $(VENDOR), $(BOARD) here and there in makefiles and CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD} in C source files. I took an action little by little to reduce the number of such variables in makefiles For example, these patches: http://patchwork.ozlabs.org/patch/335202/ http://patchwork.ozlabs.org/patch/335201/ I want to do something with CONFIG_SYS_{ARCH,...} in this series. Masahiro Yamada (3): env: drop CONFIG_ENV_VARS_UBOOT_CONFIG support cmd_pxe: remove SoC, ARCH path from pxe_default_path mkconfig: Do not define CONFIG_SYS_{ARCH,CPU,SOC,VENDOR,BOARD} in config.h.
