USB Consolidate descriptor definitions

2009-12-20T11:47:37+00:00

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.

usb.h: use standard __LITTLE_ENDIAN from Linux headers

2009-01-28T18:57:29+00:00

Rather than forcing people to define a custom "LITTLEENDIAN", just use the
__LITTLE_ENDIAN one from the Linux byteorder headers that every arch is
already setting up.

USB: descriptor handling

2008-12-09T20:26:45+00:00

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).
