Yes. For the verification to hold, DMA needs to be off, or the driver (and hardware) for the DMA device needs to be trusted/verified.
We're working on eliminating that for A15 with SystemMMUs, but that will be a while.

Does the use of DMA invalidate security guarantees in the ARM ports (and KZM in particular) currently?
