001a831986 usb: dfu: introduce dfuMANIFEST state
on nand flash using ubi, after the download of the new image into
the flash, the "rest" of the nand sectors get erased while flushing
the medium. With current u-boot version dfu-util may show:

Starting download: [##################################################] finished!
state(7) = dfuMANIFEST, status(0) = No error condition is present
unable to read DFU status

as get_status is not answered while erasing sectors, if erasing
needs some time.

So do the following changes to prevent this:

- introduce dfuManifest state
  According to dfu specification
  ( http://www.usb.org/developers/devclass_docs/usbdfu10.pdf ) section 7:
  "the device enters the dfuMANIFEST-SYNC state and awaits the solicitation
   of the status report by the host. Upon receipt of the anticipated
   DFU_GETSTATUS, the device enters the dfuMANIFEST state, where it
   completes its reprogramming operations."

- when stepping into dfuManifest state, sending a PollTimeout
  DFU_MANIFEST_POLL_TIMEOUT in ms, to the host, so the host
  (dfu-util) waits the PollTimeout before sending a get_status again.

e0059eaef1 usb:udc:samsung: Zero copy approach for data passed to Samsung's UDC driver
The Samsung's UDC driver is not anymore copying data from USB requests to
aligned internal buffers. Now it works directly in data allocated in the
upper layers like UMS, DFU, THOR.

This change is possible since those gadgets now must take care to allocate
buffers aligned to cache line (CONFIG_SYS_CACHELINE_SIZE).

This can be achieved by using DEFINE_CACHE_ALIGN_BUFFER() or
ALLOC_CACHE_ALIGN_BUFFER() macros. Those take care to allocate buffer
aligned to cache line in both starting address and its size.
Sometimes it is enough to just use memalign() with size being a
multiplication of cache line size.

716662bd19 usb:udc:samsung: Remove redundant cache operation from Samsung UDC driver
A set of cache operations (both invalidation and flush) were redundant
in the S3C HS OTG Samsung driver:

1. s3c_udc_ep0_zlp - to transmit EP0's ZLP packets one don't need to flush
the cache (since it is the zero length transmission)

2. s3c_udc_pre_setup and s3c_ep0_complete_out - cache invalidation is not
needed when the buffer for OUT EP0 transmission is setup, since no data
has yet arrived.

Cache cleanups presented above don't contribute much to transmission speed
up, hence shall be regarded as cosmetic changes.

3. setdma_rx - here the s3c UDC driver's internal buffers were invalidated.
This call is not needed anymore since we reuse the buffers passed from
gadgets. This is a key contribution to transmission speed improvement.

dcad280056 usb: gadget: fotg210: EP0 fifo empty indication is non-reliable
The fifo size of ep0 is 64 bytes, and if the packet size grater than
64 bytes, the driver would have to fill up the fifo multiple times,
and before filling up the fifo, the driver should make sure the fifo
is empty by checking fifo empty indication.

However there is a hardware bug that the fifo empty indication is
somehow a bit earlier than fifo reset. So if I don't add an extra
delay here, the data might be corrupted. (i.e., 1 byte missing)

After a couple of tests, it truns out that 1 usec is good enough.

This workaround should be applied to all hardware revisions.

1. Interrupt Source Group 0 Register (0x144) (EP0 Abort: BIT5)
2. Interrupt Source Group 2 Register (0x14C) (All bits)

And before revision 1.11.0, these registers are all R/W.
Which means software must write a 0 to clear the status.

The hs_source_desc, hs_sink_desc, already have their wMaxPacketSize

Strictly speaking, this patch is not needed because
usb_ep_autoconfig will call ep_matches which will
override wMaxPacketSize for BULK endpoints only with
the size associated with the endpoint setup by the udc driver.
But if you want to rely on this, you may as well combine the
full speed descriptor with the high speed descriptor to
minimize confusion.

898d686eea usb: gadget: config: fix unaligned access issues
As seen with codesourcery compiler 2010q1, the buf pointer in
usb_request structure is not aligned on 4 bytes boundary causing
data aborts in eth_setup -> conf_buf -> usb_gadget_config_buf.
Make it as align access to fix this issue.

5290759cc4 usb: gadget: Fix data aborts during USB ethernet boot
As seen on GCC 4.6 Linaro compiler, control_req buffer is not aligned
on 4 byte boundaray causing data aborts in eth_setup -> conf_buf
during dhcp boot over usb_ether. Fix the issue my aligning control_req
buffer using DEFINE_CACHE_ALIGN_BUFFER.

Tested on am335x_evm platform (beaglebone).
Applies on 2013.10-rc1 branch.

The manufacturer and product IDs are dynamically assigned when gadget is
