+// Some notes about this driver:
+//
+// First as it stands all transfers are routed through the "nonperiodic" queues
+// including interrupt transfers. This means we emulate interrupt transfers using
+// the UEFI timer and a queue. All the fancy hardware scheduling is unused.
+//
+// This also means that there is absolutely no prioritization, bandwidth reservations
+// or anything else that are generally required of interrupt/isochronous transfers.
+//
+// We no round robin the channels, this in theory allows us to have multiple commands
+// outstanding, but due to the fact that we are either using a timer and mostly
+// blocking thta timer during the command submission, its really unlikely that we
+// have more than a single command outstanding.
+//
+// At the moment this is host only driver, and the phy config, which should be attached
+// to the DW i2c channel likely isn't.
+//
+// This driver defaults to High speed, but if we detect split transaction problems with
+// low/full speed devices then we reset the root port and everything attached, and restart
+// at a lower speed. This allows us to transparently support high/full/low speed devices.
+// That said, it seems low speed devices don't really work worth a darn on this controller.
+// There are assorted knobs that can be tiwiddled to tweak the low speed bitstream, but
+// my USB analyzer is truly just a protocol analyzer and is unable to tell me how far out
+// of spec the physical singaling is, and I'm currently to lazy to try an analyze it
+// with my scope/logic analyzer.
+//
+
+#include "DwUsbHostDxe.h"
+#include "DwcHw.h"
+
+// Enabling this, disables attempting split transactions, and
