Error: You must add new CONFIG options using Kconfig

Error: You must add new CONFIG options using Kconfig
The following new ad-hoc CONFIG options were detected:
CONFIG_ADC
Please add these via Kconfig instead. Find a suitable Kconfig
file and add a ‘config’ or ‘menuconfig’ option.

解决方案

在u-boot/scripts/config_whitelist.txt中增加新检测到的config. “CONFIG_ADC”。
注意根据字母排序顺序加入正确的位置。
