This is the USB host controller used on the Altera SoCFPGA and Raspbery Pi.
This code has three checkpatch warnings, but to make sure it stays at least
readable and clear, these are not fixed. These bugs are in the USB request
handling combinatorial logic, so any abstracting of those is out of question.
Tested on DENX MCV (Altera SoCFPGA 5CSFXC6C6U23C8N) and RPi B+ (BCM2835).

Former usb_cable_connected() patch broke compilation of boards which do
not support this feature.
I've renamed usb_cable_connected() to g_dnl_usb_cable_connected() and added
its default implementation to gadget downloader driver code. There's
only one driver of this kind and it's unlikely there'll be another, so
there's no point in keeping it in /common.
Previously this function was declared in usb.h. I've moved it, since
it's more appropriate to keep it in g_dnl.h - usb.h seems to be intended
for USB host implementation.
Existing code, confronted with default -EOPNOTSUPP return value,
continues as if the cable was connected.
CONFIG_USB_CABLE_CHECK was removed.

This patch allows exiting from UMS mode to u-boot prompt
by detaching usb cable or by pressing ctrl+c.
Add new config: CONFIG_USB_CABLE_CHECK. If defined then board
file should provide function: usb_cable_connected() (include/usb.h)
that return 1 if cable is connected and 0 otherwise.

This adds stack layer for eXtensible Host Controller Interface
which facilitates use of USB 3.0 in host mode.
Adapting xHCI host controller driver in linux-kernel
by Sarah Sharp to needs in u-boot.
Initial porting from Linux kernel version 3.4, with following
top commit history of drivers/usb/host/xhci* :
cf84055 xHCI: Cleanup isoc transfer ring when TD length mismatch found
This adds the basic xHCI host controller driver with bare minimum
features:
- Control/Bulk transfer support has been added with required
infrastructure for necessary xHC data structures.
- Stream protocol hasn't been supported yet.
- No support for quirky devices has been added.

Backend driver for MUSB OTG controllers found on TI AM35x.
It seems that on AM35X interrupt status registers can be updated
_before_ core registers. As we don't use true interrupts in U-Boot
and poll interrupt status registers instead this can result in
interrupt handler being called with non-updated core registers.
This confuses the code and result in hanged transfers.
Add a small delay in am35x_interrupt as a workaround.

Linux usb/ch9.h seems to have all the same information (and more)
as usbdescriptors.h so use the former instead of the later one.
As a consequense of this change USB_SPEED_* values don't correspond
directly to EHCI speed encoding anymore, I've added necessary
recoding in EHCI driver. Also there is no point to put speed into
pipe anymore so it's removed and a bunch of host drivers fixed to
look at usb_device->speed instead.
Old usbdescriptors.h included is not removed as it seems to be
used by old USB device code.
This makes usb.h and usbdevice.h incompatible. Fortunately the
only place that tries to include both are the old MUSB code and
it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute
on musb_regs structure but this attribute seems to be unneeded
(old MUSB code doesn't support any DMA at all).

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(...).

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.

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).

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.
