The document says:
|2.1 Problem description
|    When at least two USB devices are simultaneously running, it is observed that
|    sometimes the INT corresponding to one of the USB devices stops occurring. This may
|    be observed sometimes with USB-to-serial or USB-to-network devices.
|    The problem is not noticed when only USB mass storage devices are running.
|2.2 Implication
|    This issue is because of the clearing of the respective Done Map bit on reading the ATL
|    PTD Done Map register when an INT is generated by another PTD completion, but is not
|    found set on that read access. In this situation, the respective Done Map bit will remain
|    reset and no further INT will be asserted so the data transfer corresponding to that USB
|    device will stop.
|2.3 Workaround
|    An SOF INT can be used instead of an ATL INT with polling on Done bits. A time-out can
|    be implemented and if a certain Done bit is never set, verification of the PTD completion
|    can be done by reading PTD contents (valid bit).
|    This is a proven workaround implemented in software.

Russell King run into this with an USB-to-serial converter. This patch
implements his suggestion to enable the high frequent SOF interrupt only
at the time we have ATL packages queued. It goes even one step further
and enables the SOF interrupt only if we have more than one ATL packet
queued at the same time.

This is a patch that seems to make the USB hangs on the S3C244X go away.
At least a good amount of ping torture didn't make them come back so far.

The issue is that, if there are several back-to-back packets, sometimes no
interrupt is generated for one of them. This seems to be caused by the
mysterious dual packet mode, which the USB hardware enters automatically
if the endpoint size is half that of the FIFO. (On the 244X, this is the
normal situation for bulk data endpoints.)

There is also a timing factor in this. It seems that what happens is that
the USB hardware automatically sends an acknowledgement if there is only one
packet in the FIFO (the FIFO has space for two). If another packet arrives
before the host has retrieved and acknowledged the previous one, no interrupt
is generated for that second one.

However, there may be an indication. There is one undocumented bit (none
of the 244x manuals document it), OUT_CRS1_REG[1], that seems to be set
suspiciously often when this condition occurs. There is also
CLR_DATA_TOGGLE, OUT_CRS1_REG[7], which may have a function related to
this. (The Samsung manual is rather terse on that, as usual.)

This needs to be examined further. For now, the patch seems to do the
trick.

This PCH_UDC driver does not work normally when "Ethernet gadget" is used.

This patch fixed this issue.
The following was modified.
 - The FIFO flush process.
 - The descriptor creation process.
 - The adjustment of DMA buffer align.

Currently the PCH_UDC driver can work normally with "Ethernet gadget",
"Serial gadget" or "File-backed Storage Gadget".

Add an m68k/coldfire optimized memmove() function for the m68knommu arch.
This is the same function as used by m68k. Simple speed tests show this
is faster once buffers are larger than 4 bytes, and significantly faster
on much larger buffers (4 times faster above about 100 bytes).

This also goes part of the way to fixing a regression caused by commit
ea61bc46 ("m68k/m68knommu: merge MMU and
non-MMU string.h"), which breaks non-coldfire non-mmu builds (which is
the 68x328 and 68360 families). They currently have no memmove() fucntion
defined, since there was none in the m68knommu/lib functions.

The m68k arch implements its own memcmp() function. It is not optimized
in any way (it is the most strait forward coding of memcmp you can get).
Remove it and use the kernels standard memcmp() implementation.
