Re: understanding battable

- Why is battable an array with 512 entries? 16 should be enough.

That's because the MPC601 can translate only up to 8M per BAT, as opposed other, less limited OEA implementations, an thus needs that many entries. (You can check dsi601trap; it differs, among other details, in the amount of fault address -> battable entry# shifting.)
