| Subject: [PATCH] Makefile: Change COUNTER_FREQ to 100 MHz |
| |
| Older Arm Fast Models (AEM < RevC) had a base frequency of 24 MHz. but |
| the RevC base models use 100 MHz. There is not a robust method of |
| determining the configured base frequency at runtime, so update |
| COUNTER_FREQ to be 100 MHz. |
