EHCI Problem on FreeBSD arm port

Hi all,

Bruce M Simpson has donated me an Emprex NSD 100 for porting FreeBSD
to it, and currently I am working to port FreeBSD to this machine,
which is ARM SoC Cavium Econa CNS11XX (formerly Star 91XX).

But now I am stuck in implementing the USB EHCI controller. Before
getting into the question, I would like to give some background. This
SoC uses Faraday FA526 Arm CPU (arm4), and I have worked on Linux port
of this SoC.

The current progress is as follows:
- FA526 CPU support is working (taken from NetBSD with minor adjustment)
- Interrupt controller, timer, and serial console is working

There are several more things that i need to implement: EHCI
controller driver, OHCI controller driver, and network driver. I am
starting with EHCI because then I would be able to use USB disk for
booting, and I will be able to use my USB-Ethernet adapter (supported
by FreeBSD) to test the networking stuff.

This is where I got stuck. The EHCI controller is detected, most of
the time the hub is detected (2 ports), and some of the time the USB
mass controller is loaded. From my observation, it seems that even
though the USB transaction is completed successfully, it sometimes
doesn't return correct data. By "completing successfully", The result
is (error=0):

ehci_device_done:2149: xfer=0xc19360b0, pipe=0xc192b878, error=0

It is obvious that the data is sometimes invalid, because the display
name of the device is sometimes corrupted.

For example, this is when it is ok (see: "Kingston DataTraveler"):

pass0: <Kingston DataTraveler 2.0 1.00> Removable Direct Access SCSI-2 device

and when it is error ("Kingston DataTravele2F921"):

umass0: <Kingston DataTravele2F921, class 0/0, rev 2.00/1.00, addr 2> on usbus0

(and sometimes even weirder string is shown)

This invalid data happens randomly, and causes the error to move
around (USB_ERR_NO_PIPE, CAM_REQ_CMP_ERR, etc). I have checked these
parts:

- I have verified that the device itself is working fine in Linux (always fine)
- the Linux implementation doesn't have any quirks for this SoC's EHCI
controller
- Timer: the timer is working OK, so this should not be a timing problem
- Interrupt controller: interrupt controller is also working OK, EHCI
interrupt handler is called as it should
- Caching/sync problem. I don't have deep understanding about ARM
cache mechanism, but I have tried adding a code to flush the all of
Dcache at the end of ehci_device_done, and it doesn't help.

My current code is quite messy (many debugging printf). I am currently
cleaning the source code so that everyone can have a look. But while I
am cleaning, maybe anyone can point out things that I need to check.

Here is the boot log of the most successful boot.
