This feature is inspired by /proc/config.gz of Linux. In Linux, if CONFIG_IKCONFIG is enabled, the ".config" file contents are embedded in the kernel image. If CONFIG_IKCONFIG_PROC is also enabled, the ".config" contents are exposed to /proc/config.gz. Users can do "zcat /proc/config.gz" to check which config options are enabled on the running kernel image. The idea is almost the same here; if CONFIG_CMD_CONFIG is enabled, the ".config" contents are compressed and saved in the U-Boot image, then printed by the new command "config". The usage is quite simple. Enable CONFIG_CMD_CONFIG, then run > config from the command line interface. The ".config" contents will be printed on the console. This feature increases the U-Boot image size by about 4KB (this is mostly due to the gzip-compressed .config file). By default, it is enabled only for Sandbox because we do not care about the memory footprint on it. Of course, this feature is architecture agnostic, so you can enable it on any board if the image size increase is acceptable for you.
