1b86e5fc83 samd51: Enable functionality to support CPython stdlib 
This enables various things in order to support the CPython standard library.

MICROPY_PY_BUILTINS_NOTIMPLEMENTED:
Support NotImplemented for easy conversion of stdlib.
It doesn't do fallbacks though, only raises TypeError.

MICROPY_PY_COLLECTIONS_ORDEREDDICT:
collections.OrderedDict

MICROPY_PY_FUNCTION_ATTRS:
Support function.__name__ for use as key in the function attribute workaround.

MICROPY_PY_IO:
uio module: BytesIO, FileIO, StringIO, TextIOWrapper
Also add 'io' alias.

MICROPY_PY_REVERSE_SPECIAL_METHODS:
Support the __r*__ special methods.

MICROPY_PY_SYS_EXC_INFO:
sys.exc_info() used by unittest when collecting exceptions.

MICROPY_CPYTHON_COMPAT:
Some of the things it adds:

>>> object.__init__
<function>
>>> object.__new__
<function>
>>> object.__class__
<class 'type'>
>>> object().__class__
<class 'object'>
>>> object.__name__
'object'

>>> 'Hello'.encode()
b'Hello'
>>> b'Hello'.decode()
'Hello'

Named tuple field names from string:
namedtuple('Point', 'x y')

cec9a69a15 samd51: Make errno, os, and time module aliases 
Add alias for uerrno so the user doesn't have to know about the
CircuitPython special names for the module.

Make os and time weak modules (aliases) making it possible to add
functionality to those modules written in python.

Example:
'import os' will now look in the path for an os module and if not found
it will import the builtin module. An os module written in python will
import the builtin module through its name prefixed with an underscore
(_os) following the C module naming practice in CPython.

Also right align the macro values to increase readability making it
easier to compare the values for samd21 and samd51. Even the longest
macro from py/mpconfig.h will fit with this alignment.

Ramp values to and from a default value while active. 
This reduces the popping sound on initial playback of an audio
sample.

The M4 DAC has a pop on startup that cannot be prevented. It also
does not allow readback so current values of the DAC are ignored.

Introduce displayio to render graphics to displays. 
It's designed to minimize RAM footprint by using Sprites to
represent objects on the screen. The object model also facilitates
partial screen updating which reduces the bandwidth needed to display.

This is all handled in C. Python simply manipulates the objects with
the ability to synchronize to frame timing.

Compress all translated strings with Huffman coding. 
This saves code space in builds which use link-time optimization.
The optimization drops the untranslated strings and replaces them
with a compressed_string_t struct. It can then be decompressed to
a c string.

Builds without LTO work as well but include both untranslated
strings and compressed strings.

This work could be expanded to include QSTRs and loaded strings if
a compress method is added to C. Its tracked in #531.

b0e33f6a11 atmel-samd: UART: allocate rx buffer in long-lived region 
This is not strictly needed in order for #1056 to be resolved,
because the "make long-lived" machinery is unaware of this pointer.

However, as UARTs are assumed to be long-lived, this change is
beneficial because it moves the long-lived buffer into the upper
memory area with other long-lived objects, instead of remaining in
the low heap.

2fbab8067a Prevent freezing USB during high frequency PulseIn. 
We now track the last time the background task ran and bail on the
PulseIn if it starves the background work. In practice, this
happens after the numbers from pulsein are no longer accurate.

This also adjusts interrupt priorities so most are the lowest level
except for the tick and USB interrupts.

e580d22f4a Use the external crystal on SAMD21 again. 
Also, re-enable calibration storage for CircuitPlayground Express.
Tested with a 500hz PWMOut on Metro M0 with Saleae:
 * with crystal 500hz
 * with usb 500hz +- 0.1hz
 * without either 487hz += 0.1hz

SAMD51 is skipped due to DFLL errata and the fact it defaults to a
factory calibrated 48mhz that works fine for USB.

e158702a68 atmel-samd/samd51: Use crystal for RTC 
This uses the crystal to clock the RTC on boards which have a crystal.

Disable clock generator 2 which was enabled in commit
8e2080411f ("atmel-samd: Add rtc module support").
samd51 differs from samd21 when it comes to the RTC clock. samd51 doesn't
have an explicit clock peripheral so no need for a clock generator.

The same commit didn't even setup XOSC32K correctly, it missed EN1K and XTALEN.

The RTC uses the 1k clock output, so enable it on the OSCULP32K even if it works without it.

ab7ddfddd5 atmel-samd/samd51: Refactor clock setup 
Refactor the convoluted asf4 clock setup into something more readable.

enable_clock_generator() has 2 changes:
- Set 'Output enabled' to match the current clock setup
- Handle divisors above 511

Add an enable_clock_generator_sync() version which makes it possible to setup
clocks without waiting for syncing. The bootup would hang without this.

I have checked these registers:

 NVMCTRL->CTRLA = 0x00000004

 Peripheral clocks (only non-zero shown):
 PCHCTRL[1]=0x00000045
 PCHCTRL[10]=0x00000041

 Generator clocks (only non-zero shown):
 GENCTRL[0] = 0x00010907
 GENCTRL[1] = 0x00010906
-GENCTRL[2] = 0x00041104
+GENCTRL[2] = 0x00200904
 GENCTRL[4] = 0x00010907
 GENCTRL[5] = 0x00180906

 DFLL clock:
 OSCCTRL->DFLLCTRLA = 0x00000082
 OSCCTRL->DFLLCTRLB = 0x00000000
 OSCCTRL->DFLLVAL = 0x00008082
 OSCCTRL->DFLLMUL = 0x00000000

 DPLL clocks:
 OSCCTRL->Dpll[0].DPLLCTRLA=0x00000002
 OSCCTRL->Dpll[0].DPLLCTRLB=0x00000000
 OSCCTRL->Dpll[0].DPLLRATIO=0x0000003b
 OSCCTRL->Dpll[1].DPLLCTRLA=0x00000080
 OSCCTRL->Dpll[1].DPLLCTRLB=0x00000020
 OSCCTRL->Dpll[1].DPLLRATIO=0x00000000

 OSC32KCTRL clock:
 OSC32KCTRL->RTCCTRL = 0x00000000
 OSC32KCTRL->XOSC32K = 0x00002082
 OSC32KCTRL->CFDCTRL = 0x00000000
 OSC32KCTRL->EVCTRL = 0x00000000
 OSC32KCTRL->OSCULP32K = 0x00002300

Only gen2 changed which is due to samd51 having more bits in the simple
division register so DIVSEL wasn't necessary, and it didn't have OE set.

Make clock setup explicit instead of using the convoluted asf4 macro setup.

enable_clock_generator():
- Add GCLK_GENCTRL_OE to stick with the current setup.
- Handle divisor larger than 31 for generator 2
- Change the source argument so it can take the GCLK_GENCTRL_SRC_XXXX_Val
  macros without casting to uint8_t.

This patch should not introduce any functional changes except keeping
GCLK_GENCTRL_OE enabled when the I2S clock is enabled.

28642ab10d Add audio output support! 
This evolves the API from 2.x (and breaks it). Playback devices are now
separate from the samples themselves. This allows for greater playback
flexibility. Two sample sources are audioio.RawSample and audioio.WaveFile.
They can both be mono or stereo. They can be output to audioio.AudioOut or
audiobusio.I2SOut.

Internally, the dma tracking has changed from a TC counting block transfers
to an interrupt generated by the block event sent to the EVSYS. This reduces
the overhead of each DMA transfer so multiple can occure without using up TCs.

Fixes #652. Fixes #522. Huge progress on #263

right at the end of SRAM.

I verified by reading the source that the 4-byte-aligned address is
used for all samd21 / samd51 boards in
adafruit/circuitpython@efbf08266b.  However, I only tested on
trinket_m0.

It also uses up 4 directory entries (out of 128), but does not reduce
the number of blocks usable for storing file contents.

These are the same items noted in the Adafruit README for Trinket M0
as preventing MacOS indexing.

dddfad6594 UART: Fix maybe-uninitialized diagnostic 
The following error occurs when building with gcc 5.4.1 (debian stretch):

common-hal/busio/UART.c:104:83: error: 'sercom_index' may be used uninitialized in this function [-Werror=maybe-uninitialized]
                   sercom_insts[rx->sercom[j].index]->USART.CTRLA.bit.ENABLE == 0) ||

It may be related to the addition of rx-only UARTs; gcc is unable
to infer the intended relationship between have_tx and sercom_index
being set (I am still not entirely confident of it myself)

Having the `active_read = false` in the background function left
a chance that a new_write occurs before active_read is set to false.

and never clear the active write.

Hopefully fixes #655.

b001c0711b Correct _etext location; clean up .ld files 
1. Make _extext and _sidata coincide. Old _etext location did not include
.ARM.exidx sections, which were usually absent but not always. So flash
data was copied to RAM in wrong place.
2. Use decimal constants with "K" and "M" suffixes in .ld files instead
of hex constants, to make them easier to read and check for accuracy.

* Be more liberal with critical sections to ensure ordering.
* Correct usb_busy so that it is busy when no errors occur on

  momentarily until a second transfer was attempted and a busy
  error was returned, therefore setting usb_busy to true. That
  risks the first "failed" transfer completing before a second one
  is attempted.

4140b3b944 atmel-samd: Stop double CSW after MSC reads 
This explicit zero length xfer leads to a second CSW packet. If
another read was started between the two CSWs then the host gets
confused and resets the device.

On reads, the CSW is automatically sent when we reply with the
total length. Writes must do it manually so they can wait for the
disk to flush the data.
