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/def/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.

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 where

KCONFIG_ALLCONFIG == "" or KCONFIG_ALLCONFIG == "1", "make *config"

checks for a file named "all{yes/mod/no/def/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
