ddr_config-c

ddr_config takes the default input file, ddr.dbase, and builds a new device database. This command takes effect immediately, without having to rebuild the kernel.

Note: ddr.dbase is a UNIX shell script and is not written in C. This means # is used to signify a comment, not /* and */ or //, as used in C. Make sure any comments included in this file are preceded with the # character.
