| * @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. |
