+ * 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.
