Save the file. Then run the following command:
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.
