This has the intentions of growing into a fully-featured driver, but so far my only development platform has been an Arm FVP (software model) which doesn't emulate peripheral requests, so this is as far as I've been able to get with dmatest alone. However, I figure it's enough to be worth posting for review, at the very least. Thanks, Robin.
