(What I think) I have done: Have 3.14.3 still booting with legacy board init (please don't kill me for that). Without applying your patch old OMAP3530 crashed at every reboot with SYNCH_LOST. After applying your patch reboot works fine. Looking into id-code makes me wonder what changes on 36xx-features do to 35xx devices (treated as 34xx - right?). The only way that this happens is for unknown hawkeye fallthough. I suggest you simply forget my note and I will find out what really 'fixed' dss reboot problem.
