+  @param  This                  A pointer to the EFI_USB_HC_PROTOCOL instance.
+  @param  DeviceAddress         Represents the address of the target device on the USB,
+                                which is assigned during USB enumeration.
+  @param  EndPointAddress       The combination of an endpoint number and an endpoint
+                                direction of the target USB device. Each endpoint address

+                                the EndPointAddress represents an interrupt endpoint.
+  @param  IsSlowDevice          Indicates whether the target device is slow device
+                                or full-speed device.
+  @param  MaxiumPacketLength    Indicates the maximum packet size the target endpoint

+  @param  IsNewTransfer         If TRUE, an asynchronous interrupt pipe is built between
+                                the host and the target interrupt endpoint.

+                                the subsequent asynchronous interrupt transfer.
+  @param  PollingInterval       Indicates the interval, in milliseconds, that the
+                                asynchronous interrupt transfer is polled.
+                                This parameter is required when IsNewTransfer is TRUE.

+                                is only required when IsNewTransfer is TRUE.

+                                rate specified by PollingInterval.This parameter is

+// 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 
+// sets the initial root port to full speed (rather than high)
+// This option is less useful now that we detect full/low speed
+// devices having split transaction problems and automatically 
+// reset to full speed
+#define DW_AT_FULLSPEED 0

Hi Kalyan,

This is a huge (and much appreciated) contribution.
However, in order to simplify reviewing, could you please:
1) Configure your edk2-platforms clone as described in
   https://github.com/tianocore/tianocore.github.io/wiki/Laszlo's-unkempt-git-guide-for-edk2-contributors-and-maintainers#contributor-workflow
   (step 5 onwards)
2) Split this patch up into
   1) DwUsbDxe
   2) DwUsbHostDxe
   3) HiKey-specific changes/additions.

It would probably also be worth cc:ing Jeremy Linton
(Jeremy.Linton@arm.com) on this set.

For some early high-level feedback:
* I see you have included UncachedMemoryAllocationLib under HiKey.
  We did delete that library for a reason - it does not really do what
  people seem to think it does.
  Ard: could you pitch in with a more suitable solution?
* The DwNonPci module is not really part of the generic driver, but
  something that could be integrated somewhere in the platform
  initialization (HiKeylib?).

Best Regards,

Leif
