While I know the DXL comes with the CAAM, I don't have access to any boards
with a DXL on it nor the DXL security manual. So I cannot validate any
changes I would make for the DXL variant.

I propose to keep the DXL out of this patch set, is that ok for you?

I'll add a compat for the QXP in V4.

Thanks! // John Ernberg
