+* Code cleanup
+
+* Various USB related patches
+ - Add support for mpc8xx USB device.
+ - Add support for Common Device Class - Abstract Control Model USB console.
+ - Add support for flow control in USB slave devices.
+ - Add support for switching between gserial and cdc_acm using environment.
+ - Minor changes to usbdcore_omap1510.c usbdcore_omap1510.h
+ - Update usbcore slightly to ease host enumeration.
+ - Fix non-portable endian problems in usbdcore and usbdcore_ep0.
+ - Add AdderUSB_config as a defconfig to enable usage of the USB console
+ by default with the Adder87x U-Boot port.

+- USB Device:
+ Define the below if you wish to use the USB console.
+ Once firmware is rebuilt from a serial console issue the
+ command "setenv stdin usbtty; setenv stdout usbtty" and
+ attach your usb cable. The Unix command "dmesg" should print
+ it has found a new device. The environment variable usbtty
+ can be set to gserial or cdc_acm to enable your device to
+ appear to a USB host as a Linux gserial device or a
+ Common Device Class Abstract Control Model serial device.
+ If you select usbtty = gserial you should be able to enumerate
+ a Linux host by
+ # modprobe usbserial vendor=0xVendorID product=0xProductID
+ else if using cdc_acm, simply setting the environment
+ variable usbtty to be cdc_acm should suffice. The following
+ might be defined in YourBoardName.h
+
+ CONFIG_USB_DEVICE
+ Define this to build a UDC device
+
+ CONFIG_USB_TTY
+ Define this to have a tty type of device available to
+ talk to the UDC device
+
+ CFG_CONSOLE_IS_IN_ENV
+ Define this if you want stdin, stdout &/or stderr to
+ be set to usbtty.
+
+ mpc8xx:
+ CFG_USB_EXTC_CLK 0xBLAH
+ Derive USB clock from external clock "blah"
+ - CFG_USB_EXTC_CLK 0x02
+
+ CFG_USB_BRG_CLK 0xBLAH
+ Derive USB clock from brgclk
+ - CFG_USB_BRG_CLK 0x04
+
+ If you have a USB-IF assigned VendorID then you may wish to
+ define your own vendor specific values either in BoardName.h
+ or directly in usbd_vendor_info.h. If you don't define
+ CONFIG_USBD_MANUFACTURER, CONFIG_USBD_PRODUCT_NAME,
+ CONFIG_USBD_VENDORID and CONFIG_USBD_PRODUCTID, then U-Boot
+ should pretend to be a Linux device to it's target host.
+
+ CONFIG_USBD_MANUFACTURER
+ Define this string as the name of your company for
+ - CONFIG_USBD_MANUFACTURER "my company"
+
+ CONFIG_USBD_PRODUCT_NAME
+ Define this string as the name of your product
+ - CONFIG_USBD_PRODUCT_NAME "acme usb device"
+
+ CONFIG_USBD_VENDORID
+ Define this as your assigned Vendor ID from the USB
+ Implementors Forum. This *must* be a genuine Vendor ID
+ to avoid polluting the USB namespace.
+ - CONFIG_USBD_VENDORID 0xFFFF
+
+ CONFIG_USBD_PRODUCTID
+ Define this as the unique Product ID
+ for your device
+ - CONFIG_USBD_PRODUCTID 0xFFFF
+

+Notes on the the generic USB-OHCI driver
+========================================
+
+This driver (drivers/usb_ohci.[ch]) is the result of the merge of
+various existing OHCI drivers that were basically identical beside
+cpu/board dependant initalization. This initalization has been moved
+into cpu/board directories and are called via the hooks below.
+
+Configuration options
+----------------------
+
+CONFIG_USB_OHCI_NEW: enable the new OHCI driver
+
+CFG_USB_OHCI_BOARD_INIT: call the board dependant hooks:
+
+ - extern int usb_board_init(void);
+ - extern int usb_board_stop(void);
+ - extern int usb_cpu_init_fail(void);
+
+CFG_USB_OHCI_CPU_INIT: call the cpu dependant hooks:
+
+ - extern int usb_cpu_init(void);
+ - extern int usb_cpu_stop(void);
+ - extern int usb_cpu_init_fail(void);
+
+CFG_USB_OHCI_REGS_BASE: defines the base address of the OHCI registers
+
+CFG_USB_OHCI_SLOT_NAME: slot name
+
+CFG_USB_OHCI_MAX_ROOT_PORTS: maximal number of ports of the root hub.
+
+
+Endianness issues
+------------------
+
+The LITTLEENDIAN #define determines if the 'swap_16' and 'swap_32'
+macros do byte swapping or not. But some cpus OHCI-controllers such as
+ppc4xx and mpc5xxx operate in little endian mode, so some extra ifdefs
+were necessary to make this work.

+ * Notes :

+ * packet to force the USB re-transmit protocol.
+ *
+ * 2. #define __DEBUG_UDC__ to switch on debug tracing to serial console
+ * be careful that tracing doesn't create Hiesen-bugs with respect to
+ * response timeouts to control requests.
+ *
+ * 3. This driver should be able to support any higher level driver that
+ * that wants to do either of the two standard UDC implementations
+ * Control-Bulk-Interrupt or Bulk-IN/Bulk-Out standards. Hence
+ * gserial and cdc_acm should work with this code.
+ *
+ * 4. NAK events never actually get raised at all, the documentation
+ * is just wrong !
+ *
+ * 5. For some reason, cbd_datlen is *always* +2 the value it should be.
+ * this means that having an RX cbd of 16 bytes is not possible, since
+ * the same size is reported for 14 bytes received as 16 bytes received
+ * until we can find out why this happens, RX cbds must be limited to 8
+ * bytes. TODO: check errata for this behaviour.
+ *
+ * 6. Right now this code doesn't support properly powering up with the USB
+ * cable attached to the USB host my development board the Adder87x doesn't
+ * have a pull-up fitted to allow this, so it is necessary to power the
+ * board and *then* attached the USB cable to the host. However somebody
+ * with a different design in their board may be able to keep the cable
+ * constantly connected and simply enable/disable a pull-up re
+ * figure 31.1 in MPC885RM.pdf instead of having to power up the board and
