That's an unusual size: it's slightly more than the second 64MB RMA
boundary, which seems to indicate there's a lot of wasted memory before
dom0 at 192MB. I wonder if this is related to the 4GB of memory in this
system. A more complete boot log might shed some light on it.

To answer your question, the 970MP (in JS21) supports the same RMA sizes
as 970 and 970FX (in JS20).
