This adds declarations for three USB peripheral controllers:
- Two high speed USB cores that can be licensed from Mentor Graphics
to be integrated into silicon:
* "musbhsfc" is for peripherals only, as found in for example the
IBM/AMCC 44EP processors.
* "musbhdrc" is OTG-capable (dual role), and is found in various
products including OMAP 2430 and the new DaVinci SOCs.
The "musbh" standing for "Mentor USB Highspeed", the rest standing
for "Function Controller" or "Dual Role Controller" (OTG-capable).
- The full speed controller on the FreeScale MPC8272.
Adding these definitions just allows gadget driver code to handle any
controller-specific logic; controller drivers are quite separate.

* USB device controllers have lots of quirks. Use these macros in

* gadget drivers or other code that needs to deal with them, and which
|
|
* autoconfigures instead of using early binding to the hardware.
|
|
*
|
|
* This SHOULD eventually work like the ARM mach_is_*() stuff, driven by
|
|
* some config file that gets updated as new hardware is supported.
|
|
* (And avoiding all runtime comparisons in typical one-choice configs!)
|
|
*
|
|
* NOTE: some of these controller drivers may not be available yet.
