|  | * | 
|  | * This header file declares prototypes for the kernel's random number generator | 
|  | * APIs. | 
|  | * | 
|  | * Typically, a platform enables the hidden CUSTOM_RANDOM_GENERATOR or | 
|  | * (for testing purposes only) enables the TEST_RANDOM_GENERATOR | 
|  | * configuration option and provide its own driver that implements | 
|  | * sys_rand32_get(). |
