I noticed in the 52259 stationery that flash address speculation is still disabled in FLASHBAR bit 6.
However, I was unable to find any errata that might indicate this is broken, like in the 52221 or 52233.
Does anyone know if it is safe to turn it on?
It sure seems to work, and gives an instant 9% performance improvement for my application, on top of the 5% that seems intrinsic in the 52259 already!
(With it turned on, 52221's and 52233's can't even boot my application.)
