3 weeks ago I asked for it "For what is worth I believe the OMAP and PMIC reset reason registers should be part of the boot log so future reboot problems can be sorted.".
But I just asked, I didn't actually code! Not sure if it is easy to retrieve both, or if PMIC is that much relevant for this issues. Anyway, this will surely take out black magic from the equation when debugging this problems.
