/**
 * @file
 * @brief Random number generator header file
 *
 * This header file declares prototypes for the kernel's random number generator
 * APIs.
 *
 * Typically, a platform enables the hidden CUSTOM_RANDOM_GENERATOR
 * configuration option and provide its own driver that implements both
 * sys_rand32_init() and sys_rand32_get(). If it does not do this, then for
 * projects that require random numbers, the project must either implement
 * those routines, or (for testing purposes only) enable the
 * TEST_RANDOM_GENERATOR configuration option.
