My estimate is am3517 is wired the same way as omap34xx with a 60%
chance, then 30% chance it's wired the same way as omap36xx, and then
10% chance for similar wiring to am335x.. So hopefully that leaves 0%
chance for yet something different for it's wiring :)

If you have a chance please give it a try. Also check the TRM for the
sgx sysconfig register bits to see which of the above matches, and if
3517 has a related rstctrl register like am335x has.

Regards,

Tony
