The README file states that the macros beginning with "CONFIG_SYS_" depend on the hardware etc. and should not be meddled with if you do not what you're doing. We have already screwed up with this policy; we have given the prefix "CONFIG_SYS_" to many user-selectable configurations. Here, "CONFIG_SYS_HUSH_PARSER" is one of them. Users can enable it if they want to use a more powerful command line parser, or disable it if they only need a simple one.
This commit attempts to rename CONFIG_SYS_HUSH_PARSER to CONFIG_HUSH_PARSER and move it to Kconfig.
Every board maintainer is expected to enable CONFIG_HUSH_PARSER (= add "CONFIG_HUSH_PARSER=y" to his defconfig file) and remove "#define CONFIG_SYS_HUSH_PARSER" from his header file.
