9bb47abf0d musb: Add Phy programming for using external Vbus
MUSB PHY on OMAP3EVM Rev >= E uses external Vbus supply to support
500mA of power.We need to program MUSB PHY to use external Vbus
for this purpose.

Adding 'extvbus' member in musb_config structure which should be set
by all the boards where MUSB interface is using external Vbus supply.

Also added ULPI bus control register read/write abstraction for
Blackfin processor as it doesn't have ULPI registers.

bbf4c01efc musb: Use name based initialization for musb_config
Changed musb_config initialization for omap3.c, davinci.c
and da8xx.c using name of structure fields. This would cause
the uninitialized field to be null by default and thus would
help in avoiding to init some flags required to be set only
for a few selected platforms.

ec2aadb408 usb: musb: fix Blackfin DMA register padding

register map.  Accessing endpoints other than ep0 with DMA would fail as
the addresses wouldn't be adjusted correctly.

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.

df402ba381 usb: musb: make fifo support configurable
The dynamic FIFO handling under MUSB is optional, and some parts (like
the Blackfin processor) do not implement support for it.

Due to this, the FIFO reading/writing steps need special handling, so
mark the common versions weak so drivers can override.

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.
