44dbc33056 usb: ohci: Do not reuse ed for interrupt endpoints of different devices
When submitting interrupt packets to an endpoint we only link in the ed
once to avoid some races surrounding unlinking of periodic endpoints,
but we share one ohci_device struct / one set of ed-s for all devices,
which means that if we have an interrupt endpoint at endpoint 1 with one
device, and a non interrupt endpoint 1 with another device we end up
with the same ed linked into both the periodic and async lists, which is
not good (tm).

This commit switches over to using separate ohci_device structs, and thus
separate ed-s for devices with interrupt endpoints, fixing this.

This fixes e.g. matching a usb storage device and keyboard on the same
usb-1 hub not working.

6a72e804a2 sunxi: ohci: Add ohci usb host controller support
This commit adds support for the OHCI companion controller, which makes
usb-1 devices directly plugged into to usb root port work.

Note for now this switches usb-keyboard support for sunxi back from int-queue
support to the old interrupt polling method. Adding int-queue support to the
ohci code and switching back to int-queue support is in the works.

8f761f023c usb: ohci: Skip unnecessary mdelay(1) calls in various places
For some reason the ohci code is full with:

 #ifdef DEBUG
		pkt_print(...)
 #else
		mdelay(1);
 #endif

AFAICT there is no reason for the mdelay(1) calls. This commit disables them
when building the ohci code for new driver-model using boards. It leaves
the mdelay(1) calls in place when building for older boards, so as to avoid
causing any regressions there.

969bb5bad3 usb: ohci: Remove unnecessary delays from hc_start and power power-on paths
The usb spec says that we must wait a minimum amount of time after port
power on (exact time is in the hub descriptor), this is something which
we must not only do for root ports but also for external hub ports, which
is why the common usb_hub code already waits a full second after powering
up ports. Having a separate wait for just the root hub in the ohci-hcd
code only leads to doing the waiting twice for the root ports, so drop the
wait from the ohci-hcd code.

47976d2c16 usb: ohci: Do not resubmit and leak urbs for interrupt packets
The u-boot usb code uses polling for all endpoints, including interrupt
endpoints, so urbs should never be automatically resubmitted.

This also fixes a leak of the urb, as submit_int_msg() did not check if
an already re-submitted urb exists before creating a new one.

b6de4d1093 dm: usb: Add support for companion controllers
USB companion controllers must be scanned after the main controller has
been scanned, so that any devices which the main controller which to hand
over to the companion have actually been handed over before we scan the
companion.

As there are no guarantees that this will magically happen in the right
order, split the scanning of the buses in 2 phases, first main controllers,
and then companion controllers.

fcdd8aaa48 dm: usb: Fix finding of first upstream usb-2 hub in the ehci dm code
The ehci driver model code for finding the first upstream usb-2 hub before
this commit has a number of issues:

1) "if (!ttdev->speed != USB_SPEED_HIGH)" does not work because the '!'
   takes presedence over the '!=' this should simply be
   "if (ttdev->speed == USB_SPEED_HIGH)"
2) It makes ttdev point to the first upstream usb-2 hub, but ttdev should
   point to the last usb-1 device before the first usb-2 hub (when going
   upstream from the device), as ttdev is used to find the port of the
   first usb-2 hub to which the the last usb-1 device is connected.
3) parent_devnum however should be set to the devnum of the first usb-2
   hub, so we need to keep pointers around to both usb_device structs.

To complicate things further during enumeration usb_device.dev will point
to the parent udevice, where as during normal use it will point to
the actual udevice, we must handle both cases correctly.

This commit fixes all this making usb-1 devices attached to usb-2 hubs,
including usb-1 devices attached to usb-1 hubs attached to usb-2 hubs, work.

7f1a07538f dm: usb: Copy over usb_device values from usb_scan_device() to final usb_device
Currently we copy over a number of usb_device values stored in the on stack
struct usb_device probed in usb_scan_device() to the final driver-model managed
struct usb_device in usb_child_pre_probe() through usb_device_platdata, and
then call usb_select_config() to fill in the rest.

There are 3 problems with this approach:

1) It does not fill in enough fields before calling usb_select_config(),
specifically it does not fill in ep0's maxpacketsize causing a div by zero
exception in the ehci driver.

2) It unnecessarily redoes a number of usb requests making usb probing slower

3) Calling usb_select_config() a second time fails on some usb-1 devices
plugged into usb-2 hubs, causing u-boot to not recognize these devices.

This commit fixes these issues by removing (*) the usb_select_config() call
from usb_child_pre_probe(), and instead of copying over things field by field
through usb_device_platdata, store a pointer to the in stack usb_device
(which is still valid when usb_child_pre_probe() gets called) and copy
over the entire struct.

*) Except for devices which are explictly instantiated through device-tree
rather then discovered through usb_scan_device() such as emulated usb devices
in the sandbox.

e13afeef6f sunxi: usb: Do not call phy_probe from hcd code
The 2/3 usb-phys on the sunxi SoCs are really a single separate functional
block, and are modelled as such in devicetree. So once we've moved all the
sunxi usb code to the driver-model then phy_probe will be called once
for the entire block from the driver-model enumeration code.

Move to this now as this also avoids problems with phy_probe being called
multiple times once we introduce ohci support. This also allows us to get rid
of the sunxi_usb_phy_enabled_count variable as phy_probe now is guaranteed
to be called only once.

Since we're effectively rewriting the probe / remove functions, move them
to the end of the file while we are at it, as that is the most logical place
for them.

fbeceb2602 dm: usb: Allow setting up a USB controller as a device/gadget
Some controllers support OTG (on-the-go) where they can operate as either
host or device. The gadget layer in U-Boot supports this.

While this layer does not interact with driver model, we can provide a
function which sets up the controller in the correct way. This way the code
at least builds (although it likely will not work).

449230f031 dm: usb: Bind generic USB devices when there is no driver
At present USB devices with no driver model driver cannot be seen in the
device list, and we fail to set them up correctly. This means they cannot
be used.

While having real drivers that support driver model for all USB devices
is the eventual goal, we are not there yet.

As a stop-gap, add a generic USB driver which is bound when we do not have
a real driver. This allows the device to be set up and shown on the bus.
It also allows ad-hoc code (such as usb_ether) to find these devices and
set them up.

0566e2403d dm: usb: Allow USB drivers to be declared and auto-probed
USB devices in U-Boot are currently probed only after all devices have
been enumerated. Each type of device is probed by custom code, e.g.:

- USB storage
- Keyboard
- Ethernet

With driver model this approach doesn't work very well. We could build
a picture of the bus and then go back and add the devices later, but
this means that the data structures are incomplete for quite a while.
It also does not follow the model of being able to bind a device when we
discover it.

We would prefer to have devices automatically be bound as the device is
enumerated. This allows us to attach drivers to particular USB classes
or product/vendor IDs. This is the method used by Linux.

Add the required #defines from Linux, a way of declaring a USB driver and
the logic to locate the correct driver given the USB device's descriptors.

With driver model we want to make the controller state hermetic in the sense
that it is not necessary to look elsewhere to know the controller type. This
will permit a controller to implement the EHCI weak functions without
reference to global data structures.

5877de9165 usb: dwc2: retry NAK'd interrupt transfers
IIUC, interrupt transfers are NAK'd by devices until they wish to trigger
an interrupt, and e.g. EHCI controllers retry these in HW until they are
ACK'd. However, DWC2 doesn't seem to retry, so we need to do this in SW.
In practice, I've seen DWC2_HCINT_FRMOVRUN happen too. I'm not quite sure
what this error implies; perhaps it's related to how near the end of a
USB frame we're at when the interrupt transfer is initiated? Anyway,
retrying this temporary error seems to be necessary too.

With all these commits applied, both my USB keyboards (one LS Lenovo and
one FS Dell) work correctly when there is no USB hub between the SoC and
the keyboard; We still need split transactions to be implemented for hubs
to work.

e236519b73 usb: dwc2: implement interrupt transfers
As best I can tell, there's no difference between bulk and interrupt
transfers in terms of how the HW should be programmed, at least given
that we're executing one transaction at a time rather than scheduling
them into frames for maximum throughput.

This patch ends up sharing the toggle bit state between bulk and
interrupt transfers on a particular EP. However I believe this is fine;
AFAIK a given EP either uses bulk or interrupt transfers and doesn't mix
them.

This patch doesn't do anything with the "interval" parameter for
interrupt transfers, but then most other USB controller drivers in U-Boot
don't either.

It turns out that one of my keyboards is happy to work using control
transfers but the other only gives non-zero "HID reports" via interrupt
transfers.

fc909c0563 usb: dwc2: fix bulk transfers
When I created wait_for_chhltd(), I noticed that some instances of the
code it replaced expected the ACK bit to be set and others didn't. I
assumed this was an accidental inconsistency in the code, so wrote
wait_for_chhltd() to always expect ACK to be set. This code appeared to
work correctly for both enumeration of USB keyboards and operation of
USB Ethernet devices. However, this change broke USB Mass Storage (at
least my USB SD card reader). This change reverts to exactly the
original behaviour. I'm not sure why the ACK bit isn't always set
(perhaps a quirk in the USB HW or DWC2 controller), but the code works
this way!

b) Always programmed the HW to transfer to/from the start of the aligned

   the OUT data to this location too. However, for large IN transactions,
   since the copy from the aligned buffer to the "client" buffer was
   deferred until after all chunks were transferred. it resulted in each

cba1da495d include: move various macros to include/linux/kernel.h
U-Boot has imported various utility macros from Linux
scattering them to various places without consistency.

In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN,
container_of, DIV_ROUND_UP, etc.
In include/linux/compat.h are min_t, max_t, round_up, round_down,
etc.
We also have duplicated defines of min_t in some *.c files.

Moreover, we are suffering from too cluttered include/common.h.

This commit moves various macros that originate in
include/linux/kernel.h of Linux to their original position.

Note:
This commit simply moves the macros; the macros roundup,
min, max, min2, max3, ARRAY_SIZE are different
from those of Linux at this point.

229dbba9b1 usb:ehci-mx6 add phy mode query function
usb_phy_enable should return status bit, but not phy mode bit, thus
add a new function usb_phy_mode to query the PHY for it's mode and
make usb_phy_enable just return 0 but not 'phy_ctrl & USBPHY_CTRL_OTG_ID'.

Include a new board weak function board_usb_phy_mode. If board code
does not reimplement this function, it just call usb_phy_mode and return
usb_phy_mode's return value. The reason to include such a weak function
is: " SOC OTG core <--connect--> board HOST port, but no pin id for
the board host port, so board can not use usb_phy_mode to return the
phy mode, but define it's own rule."

415548d884 usb: ehci: poll_int_queue check real qtd, not the overlay
When we first start an int queue, the qh's overlay area is all zeros. This
gets filled by the hc with the actual qtd values as soon as it advances
the queue, but we may call poll_int_queue before then, in which case we
would think the transfer has completed as the hc has not yet copied the
qt_token to the overlay, so the active flag is not set.

This fixes this by checking the actual qtd token, rather then the overlay.
This also fixes a (theoretical) race where we see the completion in the
overlay and free and re-use the qtd before the hc has completed writing back
the overlay to the actual qtd.

a4539a2aa7 usb: tegra: support device mode
A few changes are made to the Tegra EHCI driver so that it can set
everything up for device-mode operation on the first USB controller.
This can be used in conjunction with ci_udc.c to operate as a USB
device.

Detailed changes are:

* Rename set_host_mode() to set_up_vbus() since that's really what it
  does.

* Modify set_up_vbus() to know whether it's initializing in host or
  device mode, and:

  - Skip the external VBUS check in device mode, since external VBUS is
    expected in this case.

  - Disable VBUS output in device mode.

* Modify init_phy_mux() to know whether it's initializing in host or
  device mode, and hence skip setting USBMODE_CM_HC (which enables host
  mode) in device mode. See the comments in that function for why this
  is safe w.r.t. the ordering requirements of PHY selection.

* Modify init_utmi_usb_controller() to force "b session valid" in device
  mode, since the HW requires this. This is done in UTMI-specific code,
  since we only support device mode on the first USB controller, and that
  controller can only talk to a UTMI PHY.

* Enhance ehci_hcd_init() to error-check the requested host-/device-mode
  vs. the dr_mode (dual-role mode) value present in device tree, and the
  HW configurations which support device mode.

* Enhance ehci_hcd_init() not to skip HW initialization when switching
  between host and device mode on a controller. This requires remembering
  which mode the last initialization used.

9b20fe6f1a usb: tegra: fix PHY selection code
The TRM for Tegra30 and later all state that USBMODE_CM_HC must be set
before writing to hostpc1_devlc to select which PHY to use for a USB
controller. However, neither init_{utmi,ulpi}_usb_controller() do this
today, so the register writes they perform for PHY selection do not
work.

For the UTMI case, this was hacked around in commit 7e44d9320e "ARM:
Tegra: USB: EHCI: Add support for Tegra30/Tegra114" by adding code to
ehci_hcd_init() which sets USBMODE_CM_HC and duplicates the PHY
selection register write. This code doesn't cover the ULPI case, so I
wouldn't be surprised if ULPI doesn't work with the current code, unless
the ordering requirement only ends up being an issue in HW for UTMI not
ULPI.

This patch fixes init_{utmi,ulpi}_usb_controller() to correctly set

e6e493f341 exynos: usb: Fix data abort on boards w/o vbus-gpio node in the DT
Commit 4a271cb1b4 doesn't take into account that fdtdec_setup_gpio()
returns success when the gpio passed to it is FDT_GPIO_NONE (no
gpio node found in the fdtdec_decode_gpio() call). This results in
calling gpio_direction_output() on invalid gpio. For this reason
executing "usb start" command on Arndale causes data abort in the
ehci-exynos driver.

Add the fdt_gpio_isvalid() check to fix that problem.

Note that there were some very minor differences between the descriptors

- USB 1.0 vs. USB 1.1
- Manufacturer/Device ID
- Max packet size
- String content

I assume these aren't relevant.

2456b97f0c ush: ehci: initialize altnext pointers in QH
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.

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.

5077f96f10 usb: ehci: Fix test mode for connected ports
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.

bb1f327d0a usb: ehci-omap: Don't softreset USB High-speed Host (UHH) Module
Fixes NFS root problems with Beagle (3530 ES1.0) when used with
external USB-ethernet adapter and "USB start" command used within
u-boot.

Soft resetting the UHH module causes instability issues on
all OMAPs so we just avoid it.

See OMAP36xx Errata
  i571: USB host EHCI may stall when entering smart-standby mode
  i660: USBHOST Configured In Smart-Idle Can Lead To a Deadlock

On OMAP4/5, soft-resetting the UHH module can put it into
Smart-Idle mode and lead to a deadlock.

On OMAP3 this doesn't seem to be the case but still instabilities
are observed on beagle (3530 ES1.0) if soft-reset is used.

This patch adds support to both Faraday FUSBH200 and FOTG210,
the differences between Faraday EHCI and standard EHCI are
listed bellow:

1. The PORTSC starts at 0x30 instead of 0x44.
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
   several ways. But since U-boot doesn't support ISOC,
   we don't have to worry about that.

not only leave RESERVED and CONFIGFLAG registers un-implemented

As an result, the PORTSC register of Faraday EHCI always

   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.

c60795f41d usb: use linux/usb/ch9.h instead of usbdescriptors.h
Linux usb/ch9.h seems to have all the same information (and more)
as usbdescriptors.h so use the former instead of the later one.

As a consequense of this change USB_SPEED_* values don't correspond
directly to EHCI speed encoding anymore, I've added necessary
recoding in EHCI driver. Also there is no point to put speed into
pipe anymore so it's removed and a bunch of host drivers fixed to
look at usb_device->speed instead.

Old usbdescriptors.h included is not removed as it seems to be
used by old USB device code.

This makes usb.h and usbdevice.h incompatible. Fortunately the
only place that tries to include both are the old MUSB code and
it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute
on musb_regs structure but this attribute seems to be unneeded
(old MUSB code doesn't support any DMA at all).

5cec214ecd ehci-hcd: Boost transfer speed
This patch takes advantage of the hardware EHCI qTD queuing mechanism to avoid
software and transfer splitting overhead so as to make transfers as fast as
possible.

The only drawback is a call to memalign. However, this is fast compared to the
transfer timings, and the heap size to allocate is small, e.g. 128 kiB in the
worst case for a transfer length of 65535 packets of 512 bytes.

Tested on i.MX25, i.MX35 and i.MX51. In my test conditions, the speed gain was
very significant (several times faster), which is really appreciable when
accessing large files.

189a6956eb ehci-hcd: fix external buffer cache handling
Buffer coming from upper layers should be cacheline aligned/padded
to perform safe cache operations. For now we don't do bounce
buffering so getting unaligned buffer is an upper layer error.
We can't check if the buffer is properly padded with current
interface so just assume it is (consider changing with in the
future). The following changes are done:

1. Remove useless length alignment check. We get actual transfer
length not the size of the underlying buffer so it's perfectly
valid for it to be unaligned.
2. Move flush_dcache_range() out of while loop or it will
flush too much.
3. Don't try to fix buffer address before calling invalidate:
if it's unaligned it's an error anyway so let cache subsystem
cry about that.
4. Fix end buffer address to be cacheline aligned assuming upper
layer reserved enough space. This is potentially dangerous
operation so upper layers should be careful about that.

b8adb12095 USB: Drop cache flush bloat in EHCI-HCD
Discard the creepy cache flushing mechanisms in ehci-hcd.c and replace them with
more straightforward flushing. In the new approach, the flushing takes place
directly in ehci_submit_async() call instead of going through the QH list and
flushing all members and buffers. This discards a lot of weird bit operations
on the members of QH and qTD structures.

NOTE: Certainly, this flushes even qTDs which are possibly unused in some
transactions, though the overhead of the previous code was much higher than is
the overhead of flushing two more cache lines (which most probably aren't even
cached).

5614553d56 imx: usb: There is no such register
The reference manual of i.MX25 (nor i.MX31) does not define such
register. This seems to access read only UH2_CAPLENGTH register (if
CONFIG_MXC_USB_PORT is zero).

45b460dab3 i.MX25: usb: Set PORTSCx register
The USB controller in i.MX25 has a PORTSCx registers which should be
set. In this regard it is similar to the controller in i.MX31. As this
file is compiled only with i.MX25 and -31, #ifdef check can be removed.

90579fdd41 ehci-omap: fix for enabling the correct usb port
This is just a patch for the problem reported here:
http://lists.denx.de/pipermail/u-boot/2012-February/117580.html originally reported by Igor.

"Looks like this is copy paste error from my side,(for port2/3 it should have been bypass
 for port2/3 rather its port1 set in bypass mode)"

I only submit the patch since it is missing in 2012.04-rc3 while the twister board
depends on it. Maybe it is already somewhere in the reposistory, but I cannot find it.

note: the twister boards still needs an additional `usb reset`, don't know why.

5f4b4f2fed ehci: speed up initialization
According to EHCI specification v1.0, the controller should stabilize
the power on a port at most 20 ms after the port power bit transition.
So, we put this setting in the virtual descriptor corresponding field,
(bPwrOn2PwrGood = 10 => 10 x 2ms = 20ms), this saves about 500ms at each
controller initialization/enumeration.

With this, the EHCI seems to "recover" from a timeout. This is particularly
observable if you were to ping the wrong IP Address and then ping the correct
one or if there was a temporary failure during tftp sessions.

All it takes is one timeout to disable it. If you have a noisy network (lot
of traffic), even if the traffic is not for the board, the timeouts don't occur.

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

09c83a45b7 ehci-hcd.c: fix hanging under higher load
This patch solves a problem with USB hanging under higher load on a
i.MX31 board.  It falls into class of typical USB problems and fixes:
if you don't understand the real cause, add a delay somewhere.

The problem appeared after introduction of ELF relocation, which
results in smaller code, which appears to run faster (probably because
it fits better in the cache); turning off the instruction cache,
adding debug printf()s and increasing the delay have all been found to
make the problem go away.

Moving the original "udelay(1)" up in the code to it's new place made
the problem appear much less frequently. Increasing the delay to 2
microseconds then made the code run reliably in all (hour-long) tests.
To be on the safe side, we set it to 5 microseconds here.

9fb3b50857 EHCI: zero out QH transfer overlay in ehci_submit_async()
ehci_submit_async() doesn't really zero out the QH transfer overlay (as the EHCI
specification suggests) which leads to the controller seeing the "token" field
as the previous call has left it, i.e.:
- if a timeout occured on the previous call (Active bit left as 1), controller
  incorrectly tries to complete a previous transaction on a newly programmed
  endpoint;
- if a halt occured on the previous call (Halted bit set to 1), controller just
  ignores the newly programmed TD(s) and the function then keeps returning error
  ad infinitum.

This turned out to be caused by the wrong orger of the arguments to the memset()
call in ehci_alloc(), so the allocated TDs weren't cleared either.

While at it, stop needlessly initializing the alternate next TD pointer in the
QH transfer overlay...

8f8bd565f3 USB Consolidate descriptor definitions
The header files usb.h and usbdescriptors.h have the same nameed
structure definitions for

usb_config_descriptor
usb_interface_descriptor
usb_endpoint_descriptor
usb_device_descriptor
usb_string_descriptor

These are out right duplicates in usb.h

usb_device_descriptor
usb_string_descriptor

This one has extra unused elements

usb_endpoint_descriptor

	unsigned char	bRefresh
	unsigned char	bSynchAddress;

These in usb.h have extra elements at the end of the usb 2.0
specified descriptor and are used.

usb_config_descriptor
usb_interface_descriptor

The change is to consolidate the definition of the descriptors
to usbdescriptors.h.  The dublicates in usb.h are removed.
The extra element structure will have their name shorted by
removing the '_descriptor' suffix.

So

usb_config_descriptor -> usb_config
usb_interface_descriptor -> usb_interface

For these, the common descriptor elements are accessed now
by an element 'desc'.

As an example

-	if (iface->bInterfaceClass != USB_CLASS_HUB)
+	if (iface->desc.bInterfaceClass != USB_CLASS_HUB)

This has been compile tested on MAKEALL arm, ppc and mips.
