[Q] Cyanogenmod Kernel Configuration Option To Specific File Map - Android Q&A, Help & Troubleshooting

Hello,
I am trying to build cyanogenmod kernel for an unsupported device. As I learned, the options for kernel build are in the file cyanogenmod_xxx_defconfig.
In that file you have to specify what config you have to use (for example CCONFIG_ARM=y , CONFIG_HAVE_PWM=y). I am experiencing some build problems because if I enable some options there are other config requirements for that for example CONFIG_BT_HCIUART_H4=y requires CONFIG_BT_HCIUART=y. If you build without that there is no clear way of showing you that you are missing that config option and you have to enable it. Sometimes it does say that something is undefined, so I have to search for that word in the sources, find the missing .h file, figure it out what option does it need in the config file (sometimes unsuccessful).
I belive if a map of the config options is available somewhere will greatly help adapting cyanogenmod for other unsuported devices.
for example
CONFIG_BT_HCIUART=y (uses files from kernel\drivers\bt\.... )
|
|---------- CONFIG_BT_HCIUART_H4=y (uses files from kernel\drivers\bt\....)
If you happen to know some documentation on these files will be greatly appreciated, eventually develop a custom tool for setting those options and dependencies.
Thank you for your time.
