Many USB host controller drivers contain almost identical copies of the
same virtual root hub descriptors. Put these into a common file to avoid
duplication.
Note that there were some very minor differences between the descriptors
in the various files, such as:
- USB 1.0 vs. USB 1.1
- Manufacturer/Device ID
- Max packet size
- String content
I assume these aren't relevant.

Section 4.10.2 "Advance Queue" of ehci-specification-for-usb.pdf
specifies how an EHCI controller loads a new QTD for processing if the
QH is not already marked as active. It states:
=====
If the field Bytes to Transfer is not zero and the T-bit in the Alternate
Next qTD Pointer is set to zero, then the host controller uses the
Alternate Next qTD Pointer. Otherwise, the host controller uses the Next
qTD Pointer. If Next qTD Pointer’s T-bit is set to a one, then the host
controller exits this state and uses the horizontal pointer to the next
schedule data structure.
=====
Hence, we must ensure that the alternate next QTD pointer's T-bit
(TERMINATE) is set, so the EHCI controller knows to use the next QTD
pointer.

Use first four characters for phy_type comparison. Strcmp() should not
be used to check the phy_type string which maybe parsed by hwconfig_subarg().
Hwconfig_subarg() returns part of hwconfig string starting from
phy_type value till the end of the string. Since phy_type could be
either "utmi" or "ulpi", strncmp() should be used so that a comparison
of "utmi;fsl_ddr:bank_intlv=auto" with "utmi" will succeed.

In commit bb1f327 we removed the UHH reset to fix NFS root (over usb
ethernet) problems with Beagleboard (3530 ES1.0). However, this
seems to cause USB detection problems for Pandaboard, about (3/8).
On further investigation, it seems that doing the UHH reset is not
the cause of the original Beagleboard problem, but in the way the reset
was done.
This patch adds proper UHH RESET mechanism for OMAP3 and OMAP4/5 based
on the UHH_REVISION register. This should fix the Beagleboard NFS
problem as well as the Pandaboard USB detection problem.

The EHCI controller has some very specific requirements for the USB 2.0
port test modes, which were not closely followed in the initial test
mode commit. It demands that the host controller is completely shut down
(all ports suspended, Run/Stop bit unset) when activating test mode, and
will not work on an already enumerated port.
This patch fixes that by introducing a new ehci_shutdown() function that
closely follows the procedure listed in EHCI 4.14. Also, when we have
such a function anyway, we might as well also use it in
usb_lowlevel_stop() to make the normal host controller shutdown cleaner.

This patch adds support to both Faraday FUSBH200 and FOTG210,

2. The CONFIGFLAG(0x40) is not only un-implemented, and
also has its address space removed.
3. Faraday EHCI is a TDI design, but it doesn't
compatible with the general TDI implementation
found at both U-Boot and Linux.
4. The ISOC descriptors differ from standard EHCI in

1. The 'index' of ehci_submit_root() is not always > 0.
e.g.
While it gets invoked from usb_get_descriptor(),
the 'index' is always a '0'. (See ch.9 of USB2.0)
2. The PORTSC register is not always required, and thus it
should only report a port error when necessary.
It would cause a port scan failure if the ehci_submit_root()
always gets terminated by a port error.
