1 These files were taken from the Linux Kernel Configuration System at commit
2 089b7d890f972f6b649fedc9259f6b93a18fb970 (Feb 4, 2020) and modified for the
3 OpenWrt Buildroot:
4 - removed nconf, gconf, tests and kernel configuration targets
5 - adjusted the Makefile to compile outside the kernel
6 - always use default file when running make all{no,mod,yes}config
7 - added a 'reset' command to reset config when the target changes
8 - allow config reading from & writing to a different file
9 - allow 'source' command to use globs to include multiple files
10 - don't write auto.conf and other files under include/ directory
11 - reverted a commit to allow use of '/' & '.' in unquoted config symbols.
12 There are too many of those in OpenWrt right now.
13 - reverted a commit that was issuing a warning when there were more than
14 one help text. This is used in a few packages to use different texts
15 for the menuconfig help, and the ipkg package description.
16 - reverted an upstream change that avoids writing symbols that are not
17 visible to .config, which breaks OpenWrt busybox's '.config' generation
18 logic.
19 - add a compilation option (-DWARN_RECURSIVE_DEP) to treat recursive deps
20 as a warning, avoiding a complete build failure because of unrelated or
21 minor recursive deps, or making a scrict check before commiting a change
22 that may cause one.
23 - use pre-built *.lex.c *.tab.[ch] files by default, to avoid depending on
24 flex & bison. Rebuild/remove these files only if running make with
25 BUILD_SHIPPED_FILES defined
