Configuration Options Reference Guide

Introduction
************
Kconfig files describe the configuration symbols supported in the build
system, the logical organization and structure that group the symbols in menus
and sub-menus, and the relationships between the different configuration
symbols that govern the valid configuration combinations.
The Kconfig files are distributed across the build directory tree. The files
are organized based on their common characteristics and on what new symbols
they add to the configuration menus.
The configuration options' information below is extracted directly from
:program:`Kconfig` using the :file:`~/doc/scripts/genrest/genrest.py` script.
Click on the option name in the table below for detailed information about
each option.
