This tool takes one input file . ( let ' s say ' recipe ' file here.)
The recipe describes the list of config options you want to move .
Each line takes the form :
< config_name > < type > < default >
( the fields must be separated with whitespaces . )
< config_name > is the name of config option .
< type > is the type of the option . It must be one of bool , tristate ,
string , int , and hex .
< default > is the default value of the option . It must be appropriate
value corresponding to the option type . It must be either y or n for
the bool type . Tristate options can also take m ( although U - Boot has
not supported the module feature ) .
You can add two or more lines in the recipe file , so you can move
multiple options at once .
Let ' s say, for example, you want to move CONFIG_CMD_USB and
CONFIG_SYS_TEXT_BASE .
The type should be bool , hex , respectively . So , the recipe file
should look like this :
$ cat recipe
CONFIG_CMD_USB bool n
CONFIG_SYS_TEXT_BASE hex 0x00000000
Next you must edit the Kconfig to add the menu entries for the configs
First , you must edit the Kconfig to add the menu entries for the configs
you are moving .
And then run this tool giving the file name of the recipe
And then run this tool giving CONFIG names you want to move .
For example , if you want to move CONFIG_CMD_USB and CONFIG_SYS_TEXT_BASE ,
simply type as follows :
$ tools / moveconfig . py recipe
$ tools / moveconfig . py CONFIG_CMD_USB CONFIG_SYS_TEXT_BASE
The tool walks through all the defconfig files to move the config
options specified by the recipe file .
The tool walks through all the defconfig files and move the given CONFIGs .
The log is also displayed on the terminal .

This tool runs configuration and builds include / autoconf . mk for every
defconfig . The config options defined in Kconfig appear in the . config
file ( unless they are hidden because of unmet dependency . )
On the other hand , the config options defined by board headers are seen
in include / autoconf . mk . The tool looks for the specified options in both
of them to decide the appropriate action for the options . If the optio n
is found in the . config or the value is the same as the specified default ,
the option does not need to be touched . If the option is found in
include / autoconf . mk , but not in the . config , and the value is different
from the default , the tools adds the option to the defconfig .
of them to decide the appropriate action for the options . If the give n
config option is found in the . config , but its value does not match the
one from the board header , the config option in the . config is replaced
with the define in the board header . Then , the . config is synced by
" make savedefconfig " and the defconfig is updated with it .
For faster processing , this tool handles multi - threading . It creates
separate build directories where the out - of - tree build is run . The
