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 v2: - Rebase to mainline - Fix scripts so that there are no errors - Add the 'build-whitelist.sh' script to the tree
