Configuration Files
===================

Provide a human readable abstraction for registers in the system

    ==================================== ================================================
    ``chipsec/cfg/8086``                   platform specific configuration xml files
    ``chipsec/cfg/8086/common.xml``        common configuration
    ``chipsec/cfg/8086/<platform>.xml``    configuration for a specific <platform>
    ==================================== ================================================

Broken into common and platform specific configuration files.

Used to define controls, registers and bit fields.

Common files always loaded first so the platform files can override values.

Correct platform configuration files loaded based off of platform detection.
