We've run into kconfig missing dependency errors in the sunxi-ng code a couple times now. Each time the fix is to find the missing select statement and add it to the Kconfig entry for a particular SoC driver. Given that all this code is builtin (non-modular) we don't need to do this complicated dependency tracking in Kconfig. Instead we can move all the "library"ish code to be compiled as lib-y instead of obj-y, let the linker throw away unused code in the resulting vmlinux, and drop all the Kconfig stuff we use to track clock types.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
