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];

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.

The old swap function tended to clobber unrelated pins and screw up masks.
Rewrite the thing from scratch so it only uses the resources it needs.

The BF53x/BF56x parts do not have an on-chip ROM to boot LDRs out of

Some devices have no UART device pulled out, so allow people to disable the
driver completely in favor of other methods (like JTAG-console).

The Blackfin JTAG has the ability to pass data via a back-channel without
halting the processor. Utilize that channel to emulate a console.

Make sure we save the value of RETX at power on and then pass it on to the
kernel so that it can nicely debug a "double-fault-caused-a-reset" crash.

As pointed out by Ivan Koryakovskiy, the initialization code was not

This video driver used to live in the Blackfin cpu directory, but it was

The DEBUG code in initdram() is quite old and was never really useful, so
just drop it altogether. Common Blackfin debug code does a better job.

Some of the flash defines weren't in the correct location and caused build

The current Blackfin i2c driver does not work properly with certain devices
due to it breaking up transfers incorrectly. This is a rewrite of the
driver and relocates it to the newer place in the source tree.
Also remove duplicated I2C speed defines in Blackfin board configs and
disable I2C slave address usage since it isn't implemented.

Our dcache invalidate function doesn't just invalidate, it also flushes.
So rename the function accordingly and fix the dma_memcpy() function so it
doesn't inadvertently corrupt the data destination.

Creating a new dma_memcpy() function that skips all cache checks allows us
to use the function in very early init where the cache is not yet setup.
