[RFC RESEND 00/10] Create separate header for ehci-dbgp driver

[Chris Rorvick]

One more attempt at getting some feedback.

Original:

The FUSBH200 and FOTG210 are not EHCI-compatible and require standalone
drivers.  See discussion at:

  http://comments.gmane.org/gmane.linux.usb.general/84169

But these controllers do implement an EHCI-compatible debug port and
therefore leverage the ehci-dbgp driver.  Rather than pulling in the
necessary declarations from <linux/usb/ehci_def.h>, each driver copies
this code into their own header.  The goal of this series is to pull the
ehci-dbgp related code into its own header to remove the need for this
redundancy.

I have done only minimal testing on this, and I don't use either of
these controller so my ability to test the changes is limited.  But I
thought I'd push it out for comment to see if there was interest.

The only actual change should be when CONFIG_EARLY_PRINTK_DBGP is
disabled and CONFIG_XEN_DOM0 is enabled.  Currently each of these does
not notify Xen of reset events under this configuration.  Since these
events are propagated when CONFIG_EARLY_PRINTK_DBGP and CONFIG_XEN_DOM0
are both enabled, though, it seems that is not a problem (and maybe not
sending them in the former case is a bug?)  Regardless, the motivation
for this change is for consistancy as a step towrads consolidation.  As
I said above, I am not able to actually test these changes on either
controller.

First time submission, so I look forward to any feedback.  If this is of
any interest I will work on testing the various configations and boot
parameters.

Regards,

Chris Rorvick
