Despite the availability of Kconfig, the number of ad-hoc CONFIG options in U-Boot is still at over 8000.
In February 2015 (commit 741e58e0) there were around 8387 ad-hoc CONFIGs. As of this patch there are about 8336, only a little fewer.
One problem is that new ones are still being added, admittedly at a slower rate. This series adds a Makefile check to detect that and produce a build error. This provides immediate feedback that new CONFIG options should go in Kconfig.
Changes in v3: - Update the whitelist with mainline - Fix the match partern to exclude .py files, not anything containing "py" - Handle Kconfig files with extensions (e.g. Kconfig.64) - Handle CONFIG_SYS_EXTRA_OPTIONS containing lower case - Include lower-case letters in the CONFIG match string - Write error output to stderr so that buildman shows it - Handle Kconfig files with extensions (e.g. Kconfig.64) - Handle extra whitespace after 'config' / 'menuconfig'
Changes in v2: - Rebase to mainline - Fix scripts so that there are no errors - Add the 'build-whitelist.sh' script to the tree
