Appendix B. U-Boot Configurable Commands

U-Boot has more than 60 configurable commands. These are summarized here in Table B-1 from a recent U-Boot snapshot. In addition to these are a large number of nonstandard commands, some of which depend on specific hardware or are experimental. For the complete and up-to-date listing, consult the source code. The commands are defined in the .../include/cmd_confdefs.h header file from the top-level U-Boot source directory.
