1fa4c20c27 atmel-samd: Add Micro Trace Buffer support to the debug build. 
The Micro Trace Buffer records the history of the pc and can be used
to debug hard faults even when the stack trace is useless.

eda33385e6 atmel-samd: Correct the stack_top pointer used in garbage collection. 
Without this fix the gc will consider a large, random section of memory
and it may never finish.

7d8929c470 atmel-samd: Add I2C support. 
This commit also introduces a new shared-bindings directory which is used to store the common Python -> C binding code. By having a shared directory we can ensure that the Python API across ports is the same. Each port will have a corresponding common-hal directory which provides definitions for the C api used in the shared-bindings code. That way the compiler can enforce the C api.

To migrate to this new shared API create a common-hal directory within your port and change the Makefile to compile both the shared-bindings and common-hal files. See atmel-samd/Makefile SRC_BINDINGS for an example.

0c4f9b878a Enable REPL over USB. 
All of the code was there except the linker was failing to clear the bss section because I added too many .zeros. The should have only been the exported globals that start with _ like _szero = .. Fixing that and turn on the usb transmit fixed everything.

8f26d181c3 Blinking the LED works. Clocks should be set up correctly. 
Everything works fine without USB being plugged in but faults (I think) when USB is plugged in. This is switched away from the USB code from the bootloader onto the USB code thats generated by Atmel Studio using the high level classes from ASF.
