+DONE:
+    - functionality similar to logic testbench
+
+TODO:
+	- checkpatch.pl cleanups.
+	- keep state of DMA engines.
+	- keep data structure that keeps state of each transfer.
+	- interrupt handler should iterate over outstanding descriptor tables.
+	- complete userspace cdev to read/write using the DMA engines.
+	- split off the DMA support functions in a module, re-usable by custom
+	  drivers.

+Please coordinate work with, and send patches to
