| 33 | help |
| 34 | In some cases the timer must be accessible before driver model is |
| 35 | active. Examples include when using CONFIG_TRACE to trace U-Boot's |
| 36 | execution before driver model is set up. Enable this option to |
| 37 | use an early timer. These functions must be supported by your timer |
| 38 | driver: timer_early_get_count() and timer_early_get_rate(). |

| 80 | This is a simple sys timer driver, it is compatible with lib/time.c, |
| 81 | but does not support any interrupts. Even though SoC has 8 hardware |
| 82 | counters, they are all treated as a single device by this driver. |
| 83 | This is mostly because they all share several registers which |
| 84 | makes it difficult to completely separate them. |
