c7d703f3f3 usb.h: use standard __LITTLE_ENDIAN from Linux headers
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.

1eb734fed3 usb : usb_kbd : Populating 'priv' member of USB keyboard device_t structure
This patch populates the 'priv' field of the USB keyboard device_t
structure. The 'priv' field is populated with the address of the
'struct usb_device' structure that represents the USB device.

The 'priv' field can then be used in the 'usb_event_poll' function to
determine the USB device that requires to be polled. An
example of its usage in 'usb_event_poll' function is as below.

	device_t *dev;
	struct usb_device *usb_kbd_dev;

	<snip>

	dev = device_get_by_name("usbkbd");
	usb_kbd_dev = (struct usb_device *)dev->priv;
	iface = &usb_kbd_dev->config.if_desc[0];

db63299b1d [PATCH] Fix EHCI usb. I start to test on a
IXP465 board and I find some errors in the code. This
patch fix:
- descriptor initizialization (config, interface and endpoint
  must be one next-to the other when the USB_DT_CONFIG message
  is send.
- FIX little/endian bigendian (introduce the CONFIG_EHCI_DESC_BIG_ENDIAN
  and the CONFIG_EHCI_MMIO_BIG_ENDIAN)
- Introduce the linux version of the usb_config_descriptor and
  usb_interface descriptor. This descriptor does't contains
  u-boot extension.

Also remove duplicated I2C speed defines in Blackfin board configs and
