On a related note, it seems the PPA firmware loading is broken in current master and likely the last release. With dba1c26f70 ("arm: layerscape: ppa: reserve SDRAM region for PPA") the area where the PPA is started is mapped uncached and non-executable. That's silly of course because we jump to that area a few moments later. We have to map it uncached when the PPA returns, but not before. I think it was broken already before that patch as we call barebox_arm_entry() with the PPA area skipped, so I think the PPA range is uncached/non-executable even without this patch due to latest MMU changes. Unfortunately I found that out by bricking my board, so I can only fix that when the board is recovered.
