Samsung Kernel Modification Guidance

I've successfully downloaded and built Android OS on my Samsung phones. Now, I'm looking to make some custom features by modifying the Samsung kernel. Specifically, I want to delete some unnecessary drivers. I know which drivers need to be removed, but I'm encountering problems while building the boot after applying changes in the kernel. I'm in need of an expert who can guide me on how to properly build and modify the Samsung kernel and platform. Your expertise will help me overcome this hurdle.
