At a lot of places in the code the PIPE_INTERRUPT flags and friends
are used wrong. The wrong bits are compared to this flag resulting
in wrong conditions. Also there are macros that should be used for
PIPE_* flags.
This patch tries to fix them all, however, I was not able to test the
changes, because I do not have any of these boards.
Review required!

The max packet size is encoded as 0,1,2,3 for 8,16,32,64 bytes.
At some places directly 8,16,32,64 was used instead of the encoded
value. Made a enum for the options to make this more clear and to help
preventing similar errors in the future.
After fixing this bug it became clear that another bug existed where
the 'pipe' is and-ed with PIPE_* flags, where it should have been
'usb_pipetype(pipe)', or even better usb_pipeint(pipe).
Also removed the triple 'get_device_descriptor' sequence, it has no use,
and Windows nor Linux behaves that way.
There is also a poll going on with a timeout when usb_control_msg() fails.
However, the poll is useless, because the flag will never be set on a error,
because there is no code that runs in a parallel that can set this flag.
Changed this to something more logical.
Tested on AT91SAM9261ek and compared the flow on the USB bus to what
Linux is doing. There is no difference anymore in the early initialisation
sequence.

This patch refactors some large routines of the USB OHCI code by
making some routines smaller and more readable which helps
debugging and understanding the code. (Makes the code looks
somewhat more like the Linux implementation.)
Also made entire file compliant to Linux Coding Rules (checkpatch.pl compliant)

A recent commit (936897d4d1365452bbbdf8430db5e7769ef08d38)
enabled the usb_stop() command in common/cmd_bootm.c which was
not enabled for some time, because no board did actually set the
CFG_CMD_USB flag. So, now the usb_stop() is executed before
loading the linux kernel.
However, the usb_ohci driver hangs up (at least on AT91SAM) if the
driver is stopped twice (e.g. the peripheral clock is stopped on AT91).
If some other piece of code calls usb_stop() before the bootm command,
this command will hangup the system during boot.
(usb start and stop is typically used while booting from usb memory stick)
But, stopping the usb stack twice is useless anyway, and a flag already
existed that kept track on the usb_init()/usb_stop() calls.
So, we now check if the usb stack is really started before we stop it.
This problem is now fixed in both the upper as low-level layer.

Some of multi-function USB controllers (e.g. ISP1562) allow root hub
resetting only via EHCI registers. So, this patch adds the
corresponding kind of reset to OHCI's hc_reset() if the newly
introduced CONFIG_PCI_EHCI_DEVNO option is set (e.g. for Socrates
board).

Notice: USB on S3C6400 currently works _only_ with switched off MMU. One could
try to enable the MMU, but map addresses 1-to-1, and disable data cache, then
it should work too and we could still profit from instruction cache.

When building the 8544DS board we get this error:
In file included from r8a66597-hcd.c:22:
u-boot/include/usb.h:190:2: error: #error USB Lowlevel not defined
make[1]: *** [r8a66597-hcd.o] Error 1
The cleanest fix is to only build r8a66597-hcd.c if CONFIG_USB_R8A66597_HCD
is set.

This patch fixes bugs in usbdcore*.c related to the use of devices
with multiple configurations.
The original code made mistakes about the meaning of configuration value and
configuration index, and the resulting off-by-one errors resulted in:
* SET_CONFIGURATION always selected the first configuration, no matter what
wValue is being passed.
* GET_DESCRIPTOR/CONFIGURATION always returned the descriptor for the first
configuration (index 0).

Add new configuration variable CONFIG_PCI_OHCI_DEVNO.
In case of several PCI USB controllers on a board this variable
specifys which controller to use.
Also add USB support for sokrates board.
See doc/README.generic_usb_ohci for details.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

This patch adds CFG_OHCI_USE_NPS to the common USB-OHCI driver. This
way a board just needs to define this new option to enable the "force
NoPowerSwitching mode" instead of adding new CPU/architecture defines
to the USB source itself.
This new option will be used first with the new AMCC 460EX Canyonlands
board port, which will be posted in a few days.
This patch also fixes a small compilation problem when DEBUG is enabled.
