Oaktrail is sort of Moorestown, the divide is whether they have a PC like
set of I/O devices or not. It reflects the history of the driver

This like the non PC BIOS parsing should probably go. I've not taken it
out yet because I wanted to prove this. I'd be very surprised if it's the
right way to handle E600T but there's a bit of a lack of any public info
on that so who knows 8(.

Which is true for Oaktrail and it seems E600T

We probably want IS_GMA600() rather than IS_MRST.
