| /* |
| * Boot ROM Entry Points and such |
| */ |
| |
| /* These Blackfins all have a Boot ROM that is not reusable (at all): |
| * BF531 / BF532 / BF533 |
| * BF538 / BF539 |
| * BF561 |
| * So there is nothing for us to export ;( |
| * |
| * These Blackfins started to roll with the idea that the Boot ROM can |
| * provide useful functions, but still only a few (and not really useful): |
| * BF534 / BF536 / BF537 |
| * |
| * Looking forward, Boot ROM's on newer Blackfins have quite a few |
| * nice entry points that are usable at runtime and beyond. We'll |
| * only define known legacy parts (listed above) and otherwise just |
| * assume it's a newer part. |
| * |
| * These entry points are accomplished by placing a small jump table at |
| * the start of the Boot ROM. This way the addresses are fixed forever. |
