kconfig: resort the documentation of the environment variables
All the KCONFIG_ environment variables were previously located in a
section "Environment variables in 'menuconfig'", but neither are they
restricted to 'menuconfig' nor are they all used by 'menuconfig'.
Introduce the following three sections for these variables:
* Environment variables for '*config'
* Environment variables for '{allyes/allmod/allno/rand}config'
* Environment variables for 'silentoldconfig'
Furthermore this puts MENUCONFIG_MODE next to MENUCONFIG_COLOR into a
common section "User interface options for 'menuconfig'".

Environment variables for '*config'
|
||||
|
||||
KCONFIG_CONFIG
|
||||
--------------------------------------------------
|
||||
This environment variable can be used to specify a default kernel config
|
||||
file name to override the default name of ".config".
|
||||
|
||||
KCONFIG_OVERWRITECONFIG
|
||||
--------------------------------------------------
|
||||
If you set KCONFIG_OVERWRITECONFIG in the environment, Kconfig will not
|
||||
break symlinks when .config is a symlink to somewhere else.
|
||||
|
||||
KCONFIG_NOTIMESTAMP
|
||||
--------------------------------------------------
|
||||
If this environment variable exists and is non-null, the timestamp line
|
||||
in generated .config files is omitted.
|
||||

Environment variables for '{allyes/allmod/allno/rand}config'
|
||||
|
||||
KCONFIG_ALLCONFIG
|
||||
--------------------------------------------------
|
||||
(partially based on lkml email from/by Rob Landley, re: miniconfig)
|
||||
--------------------------------------------------
|
||||
The allyesconfig/allmodconfig/allnoconfig/randconfig variants can
|
||||
also use the environment variable KCONFIG_ALLCONFIG as a flag or a
|
||||
filename that contains config symbols that the user requires to be
|
||||
set to a specific value. If KCONFIG_ALLCONFIG is used without a
|
||||
filename, "make *config" checks for a file named
|
||||
"all{yes/mod/no/random}.config" (corresponding to the *config command
|
||||
that was used) for symbol values that are to be forced. If this file
|
||||
is not found, it checks for a file named "all.config" to contain forced
|
||||
values.
|
||||
|
||||
This enables you to create "miniature" config (miniconfig) or custom
|
||||
config files containing just the config symbols that you are interested
|
||||
in. Then the kernel config system generates the full .config file,
|
||||
including symbols of your miniconfig file.
|
||||
|
||||
This 'KCONFIG_ALLCONFIG' file is a config file which contains
|
||||
(usually a subset of all) preset config symbols. These variable
|
||||
settings are still subject to normal dependency checks.
|
||||
|
||||
Examples:
|
||||
KCONFIG_ALLCONFIG=custom-notebook.config make allnoconfig
|
||||
or
|
||||
KCONFIG_ALLCONFIG=mini.config make allnoconfig
|
||||
or
|
||||
make KCONFIG_ALLCONFIG=mini.config allnoconfig
|
||||
|
||||
These examples will disable most options (allnoconfig) but enable or
|
||||
disable the options that are explicitly listed in the specified
|
||||
mini-config files.

--------------------------------------------------
|

If this variable has a non-blank value, it prevents silent kernel

config udpates (requires explicit updates).

||||
KCONFIG_AUTOCONFIG
|
||||
--------------------------------------------------
|

This environment variable can be set to specify the path & name of the

"auto.conf" file. Its default value is "include/config/auto.conf".
|
||||
|
||||
KCONFIG_AUTOHEADER
|
||||
--------------------------------------------------
|

This environment variable can be set to specify the path & name of the
|

"autoconf.h" (header) file. Its default value is "include/linux/autoconf.h".
