62db1c0d79 SPEAr : usbd driver support for SPEAr SoCs
SPEAr SoCs contain a synopsys usb device controller.
USB Device IP can work in 2 modes
- DMA mode
- Slave mode

The driver adds support only for slave mode operation of usb
device IP. This driver is used along with standard USBTTY
driver to obtain a tty interface over USB on the host

b416191a14 Fix EHCI port reset.
In USB ehci driver, the port reset is not terminated. EHCI spec says "A host
 controller must terminate the reset and stabilize the state of the port within
 2 milliseconds". Without termination, a port stays at reset state. This is
 observed on ppc4xx(sequoia) boards.

bc72a919e0 usb: musb: change rxcsr register from write to read/modify/write
The RX Control/Status register has bits that we want to preserve, so don't
just write out a single bit.  Preserve the others bits in the process.

The original code posted to the u-boot list had this behavior, but looks
like it was lost somewhere along the way to merging.

8f8bd565f3 USB Consolidate descriptor definitions
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.

52cb4d4fb3 stdio/device: rework function naming convention
So far the console API uses the following naming convention:

	======Extract======
	typedef struct device_t;

	int	device_register (device_t * dev);
	int	devices_init (void);
	int	device_deregister(char *devname);
	struct list_head* device_get_list(void);
	device_t* device_get_by_name(char* name);
	device_t* device_clone(device_t *dev);
	=======

which is too generic and confusing.

Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev

This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.
