This patch fixes a few bugs in USB device controller driver.
The fixes are as follows
1. Adding error condition checks eg. NULL return
2. Endpoint other than endpoint 0 (control endpoint) are initialized
only if usb state machine reaches STATE_ADDRESSED or above
3. Zero length packet handling corrected
4. Dead code removed
5. Bulk out endpoint returns after servicing 1 interrupt and returns
back to service if more interrupts are pending

The earlier usb device controller driver was specific to spear platforms. This
patch implements the usb device controller driver as a generic controller which
can be reused by other platforms using this peripheral.

Clean up added ehci-omap.c and make it generic for re-use across
omap-soc having same ehci ip block. Also pass the modes to be configured
from board file and configure the ports accordingly. All usb layers
are not cache aligned, till then keep cache off for usb ops as ehci will use
internally dma for all usb ops.
* Add a generic common header ehci-omap.h having common ip block
data and reg shifts.
* Rename and modify ehci-omap3 to ehci.h retain only conflicting
sysc reg shifts remove others and move to common header file.
* pass the board data for beagle/panda accordinly to use

Adding omap-view port that helps us in using the generic ulpi
framework for any ulpi phy ops using the INSNREG05_ULPI viewport
reg available on omap platform.
Currently ehci ports are available on omap3/4 platforms so enable the same
for beagle and panda, patch is tested on the same boards.
Thanks to Igor Grinberg <grinberg@compulab.co.il> for reviewing the

In 9792987721 Stefan describes a usecase
where the previous behavior of leaving wMaxPacketSize be unaligned
caused fatal problems. The initial fix for this problem was incomplete
however as it showed another cases of non-aligned access that previously
worked implicitly. This switches to making sure that all access of
wMaxPacketSize are done via (get|put)_unaligned.
In order to maintain a level of readability to the code in some cases
we now use a variable for the value of wMaxPacketSize and in others, a
macro.

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.

Built-in Ethernet adapters support setting the mac address by means of a
ethaddr environment variable for each interface (ethaddr, eth1addr, eth2addr).
This adds similar support to the USB network side, using the names
usbethaddr, usbeth1addr, etc. They are kept separate since we don't want
a USB device taking the MAC address of a built-in device or vice versa.

As exception among the i.MX processors, the i.MX31 has headers
without general names (mx31-regs.h, mx31.h instead of imx-regs.h and
clock.h). This requires several nasty #ifdef in the drivers to
include the correct header. The patch cleans up the driver and
renames the header files as for the other i.MX processors.

Signed-off-by: Vitaly Kuzmichev <vkuzmichev@mvista.com>
Disconnecting USB gadget with pending interrupt may cause its wrong
handling in the next time when interface will be started again
(especially actual for RNDIS). This interrupt may force the gadget
to queue unexpected response before setup stage.
Despite the fact that such interrupt handled after dropped pullup
also may add pending response, this will not bring to any issues due to
usb_ep_disable (which clears the queue) called on gadget unregistering.

Changed both to use a common timeout for URB submission, since they were using
different values and EHCI's was too short.
Also fixed EHCI to actually check if urb submission succeeded, rather than
silently continuing into the weeds.

Since the ether may not be the only one usb gadget would be used
in the uboot, it is neccessary to do the register each time the
eth begin to work to make usb gadget driver less confussed when
we want to use two different usb gadget at the same time.
Usb gadget driver could simple ignore the register operation, if
it find the driver has been registered already.

This patch fixes a problem noticed on lwmon5 (PPC440EPx) using the
common EHCI driver, when "usb reset" is issued multiple times.
Upon the 2nd (and further) "usb reset" command, the command fails
with the following messages:
=> usb reset
(Re)start USB...
USB: Register 1111 NbrPorts 1

Checking the status field of the qTD token in the current code
do not take into acount cases where endpoint stall (halted) bit
is set together with XactErr status bit. As a result clearing
stall on an endpoint won't be done if this status bit was also
set. Check for halted bit and report USB_ST_STALLED status
if the host controller also indicates endpoit stall condition.

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.

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.

Commit 3ed1607 "USB: sync Queue Element Transfer Descriptor against
EHCI spec" added an "__attribute__ ((aligned (32)))" to the
declaration of struct qTD, as used for example in the Linux kernel as
well.
However, it turns out that this attribute causes errors in "usb start"
(like "ERROR: NOT USB_CONFIG_DESC 7b" and similar). Drop the attribute
again.

Appendix B "EHCI 64-Bit Data Structures" of the "Enhanced Host

1.0, March 12, 2002) defines additional fields which were missing in
U-Boot's struct qTD; as these are also present in recent versions of
struct ehci_qtd in the Linux kernel, we add them here, too.
This fixes some nasty memory corruption problems.
