-/*
- * 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.
