Is this definitely the right bit for ECCFTL? The copy of
the manual I have has "ECCFTL" as an extra bit to the left of
bit 31 (!). I'm guessing that's a docs formatting error, though...

I assumed the same thing, obviously. I could perhaps have left this out, since it seems unlikely that anyone will care about the ECC feature with qemu...
