 * Helper Functions for the Configuration Framework
 *
 * OCTEON_CN68XX introduces a flexible hw interface configuration
 * scheme. To cope with this change and the requirements of
 * configurability for other system resources, e.g., IPD/PIP pknd and
 * PKO ports and queues, a configuration framework for the SDK is
 * designed. It has two goals: first to recognize and establish the
 * default configuration and, second, to allow the user to define key
 * parameters in a high-level language.
 *
 * The helper functions query the QLM setup to help achieving the
 * first goal.
 *
 * The second goal is accomplished by generating
 * cvmx_helper_cfg_init() from a high-level lanaguage.
