Well, it is rare that we face upstream regressions of this severe kind. Every 2-3 years... We much more often have to face missing features in upstream so that we add our own patch sets on top of each -rc. In this case here we could have found this right after the merge window when v4.16-rc1 came out. But by bad chance (and holidays and other more important tasks) we did only test on GTA04 boards with standard NAND. And just now did boot a board with OneNAND installed and were surprised by this boot problem. BR, Nikolaus
