2 * Boot ROM Entry Points and such
3 */
4
5/* These Blackfins all have a Boot ROM that is not reusable (at all):
6 * BF531 / BF532 / BF533
7 * BF538 / BF539
8 * BF561
9 * So there is nothing for us to export ;(
10 *
11 * These Blackfins started to roll with the idea that the Boot ROM can
12 * provide useful functions, but still only a few (and not really useful):
13 * BF534 / BF536 / BF537
14 *
15 * Looking forward, Boot ROM's on newer Blackfins have quite a few
16 * nice entry points that are usable at runtime and beyond. We'll
17 * only define known legacy parts (listed above) and otherwise just
18 * assume it's a newer part.
19 *
20 * These entry points are accomplished by placing a small jump table at
21 * the start of the Boot ROM. This way the addresses are fixed forever.
