When available, use the on-chip syscontrol() rom function to perform a system reset rather than our own local method.

• asm("jump (%0);" : : "a" (bfin_reset));

Your comment suggests you change something, but actually you;re just adding dead code.

it's dead code because the current silicon is broken. i know the code works as ive tested it in scenarios where the anomaly isnt triggered, it just cant be enabled until fixed hardware is released. it's much easier to go back and fix 1 if statement then have to carry this patch somewhere it can got lost and i need to waste time and rewrite it. -mike
