Just to second this issue, the following commit is what broke this:
[76acc2c1a7a9a8c2cae7e9cf8d0a8b374a48aa94]
I didn't have time to delve into the whys & hows, but this commit
caused the same issue on an 8572 platform.
Reverting this one change allows everything (including 36-bit memory
access) to work correctly, as before.
