atmel-samd: Add a heap based cache for writing to flash.
...
The code will fallback to the flash scratch space when the GC
cannot allocate us enough memory.

atmel-samd: Start USB at the end so storage is initialized.

atmel-samd: Rework mass storage interaction with underlying block
...
storage to use micropython's VFS interface.
This makes mass storage work with any VFS implementation rather
than a single one.

atmel-samd: Update the Micro Trace Buffer to have better defines.
...
Same as README.md here: https://github.com/adafruit/gdb-micro-trace-buffer

atmel-samd: Support composite CDC and mass storage USB device.
...
Be careful to not use the flash file system while using mass storage
because both pieces of code attempting to change the fs can corrupt it.

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.

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.

atmel-samd: Add sys, fix import and increase the size of the heap.

atmel-samd: Support raw repl and soft reset to support ampy.
...
Closes #1 . Also adds TX and RX led support on the Arduino Zero.

atmel/samd: Support CTRL-C on USB. This won't escape native code but it will cause Python code to stop.

atmel-samd: Rename module classes so they don't conflict with names from ASF.

atmel-samd: Support Digital IO pins.
...
Also bumps up the heap size.

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.

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.
