/*
* 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.
