Add support for the inbuilt unique serial numbers in the UC3A3 and UC3A4 models.

Remove UC3B temp macros related to EEPROM, to ensure that projects requiring this break at compile time rather than at runtime until a solution can be found.

Fix Doxygen documentation, broken due to the added ATTR_PACKED attribute on some structs breaking the Doxygen parser.

Simplify AVR32 UC3B software FIFO, as it will only ever be accessed a byte at a time to prevent data alignment issues.

Add structure padding to the appropriate descriptor structures to maintain correct alignments on larger architectures.

Fix EVK1101 swapped joystick Right/Down masks.

Fix UC3B architecture compile errors and ensure the architecture can be compiled with no special makefile tokens defined.

Endpoint_ResetFIFO() renamed to Endpoint_ResetEndpoint(), to be consistent with the Pipe_ResetPipe() function name.

Fix undefined error in Pipe_UC3B.h.

Add missing migration notes.

Add software FIFOs to the UC3B pipe control interfaces, to match the endpoint control interfaces. Fix incorrect endianness for the Endpoint/Pipe read and write routines.

Porting updates for the UC3B architecture - get UC3B partially enumerating using a modified mouse demo on the EVK1101. Implement a software FIFO for the endpoint banks; datasheet hints that this can be done through hardware as on the AVR8 architecture, but the correct method to do this not discovered yet.

Fixed Still Image Host class driver exiting the descriptor search routine prematurely if the data pipes (but not event pipe) is found.

Fixed missing call to Pipe_SetInfiniteINRequests() in the Pipe_ConfigurePipe() routine.

Add in USB_INT_RegisterHandlers() internal function to register the interrupt handler routines used by LUFA. Add dummy loads after clearing the interrupt lines according to the datasheet.

Add in temporary global interrupts enable/disable macros.

Add code to start the USBB Generic Clock from the user-specified master clock source (OSCx or PLLx) in the AVR32 UC3B core USB driver.

Oops - ensure that only the relevant/available interrupts are defined and used on each architecture.

Make all USB driver headers include USBMode.h first, to ensure that the relevant USB mode macros are defined.

Changed over the AVR8 USB controller interrupt management macros to be inlined functions instead, for better compile-time validity checking and to keep the per-architecture source files as uniform as possible.

Move out common architecture-independent core definitions into the appropriate core dispatch header files.

More AVR32 UC3B architecture ports - USB device mode applications can now be sucessfully compiled, although they will be currently non-functional.

Removed Pipe_ClearErrorFlags(), pipe error flags are now automatically cleared when Pipe_ClearError() is called.

More UC3B architecture porting.

Added TWI baud rate prescaler and bit length parameters to the TWI_Init() function (thanks to Thomas Herlinghaus).

Make sure the peripheral driver .c files include the driver dispatch header, rather than the architecture specific header files.

Rename architecture specific driver files, to make them appear with uniquely identifying filenames in the documentation.

More updates to remove architecture-specific comments from the documentation, alter USBMode.h preprocessor logic to support future architectures more easily.

Start update of documentation to support possible multiple architectures in the future - alter \file documentation to automatically copy in the module documentation where possible.

Initial restructuring of the core USB driver module to support multiple architectures in the future.

Move out Dataflash IC command constants headers into the general LUFA/Drivers/Misc/ directory rather than duplicating them inside the individual board driver folders.
