71c5de4f4a ehci-hcd.c, musb_core, usb.h: Add USB_DMA_MINALIGN define for cache alignment
The USB spec says that 32 bytes is the minimum required alignment.
However on some platforms we have a larger minimum requirement for cache
coherency.  In those cases, use that value rather than the USB spec
minimum.  We add a cpp check to <usb.h> to define USB_DMA_MINALIGN and
make use of it in ehci-hcd.c and musb_core.h.  We cannot use MAX() here
as we are not allowed to have tests inside of align(...).

[ilya.yanok]: moved external buffer fixes to separate patch,
we use {ALLOC,DEFINE}_ALIGN_BUFFER macros with alignment of USB_DMA_MINALIGN
for qh_list, qh and qtd structures to make sure they are proper aligned
for both controller and cache operations.

f57661394a USB: Align buffers at cacheline
This avoids cache-alignment warnings shown in console
when a usb command is entered.

Whenever X bytes of unaligned buffer is invalidated, arm core
invalidates X + Y bytes as per the cache line size and throws
these warnings.

This moves keyboard polling logic from USB HCD drivers into USB

80b350a7ab usb: increase non-bulk timeout for slow chipsets.
If you take a look at 96820a35, you'll see the original timeout was
CONFIG_SYS_HZ.  Which is 1000.  After the mentioned change, non-bulk timeout
was changed to 100.  This causes timeout failures on the dreamplug platform
when trying to initialize the usb microsd reader.

96820a3587 Fix EHCI usb submit timeout and unify with OHCI
Changed both to use a common timeout for URB submission, since they were using

Also fixed EHCI to actually check if urb submission succeeded, rather than
silently continuing into the weeds.

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.

d277682731 USB: descriptor handling
Hi,

I found a bug when working with the u-boot USB subsystem on IXP425 processor
(big endian Xscale aka ARMv5).
I recognized that the second usb_endpoint_descriptor of the attached memory
stick was corrupted.

The reason for this are the packed structures below (either u-boot and
u-boot-usb):

--------------
/* Endpoint descriptor */
struct usb_endpoint_descriptor {
	unsigned char  bLength;
	unsigned char  bDescriptorType;
	unsigned char  bEndpointAddress;
	unsigned char  bmAttributes;
	unsigned short wMaxPacketSize;
	unsigned char  bInterval;
	unsigned char  bRefresh;
	unsigned char  bSynchAddress;

} __attribute__ ((packed));
/* Interface descriptor */
struct usb_interface_descriptor {
	unsigned char  bLength;
	unsigned char  bDescriptorType;
	unsigned char  bInterfaceNumber;
	unsigned char  bAlternateSetting;
	unsigned char  bNumEndpoints;
	unsigned char  bInterfaceClass;
	unsigned char  bInterfaceSubClass;
	unsigned char  bInterfaceProtocol;
	unsigned char  iInterface;

	unsigned char  no_of_ep;
	unsigned char  num_altsetting;
	unsigned char  act_altsetting;
	struct usb_endpoint_descriptor ep_desc[USB_MAXENDPOINTS];
} __attribute__ ((packed));
------------

As usb_endpoint_descriptor is only 7byte in length, the start of all
odd ep_desc[] structures is not word aligned. This makes wMaxPacketSize
of these structures also not word aligned.

ARMv5 Architecture however does not support non-aligned multibyte
data type (see A2.8 of ARM Architecture Reference Manual).

4886720844 fix USB initialisation procedure
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.
