5eb9f9d060 atmel-samd: Fix rebooting to bootloader 
Commit efbf08266b moved _estack in order to ensure 8-byte alignment
of the stack, but the address of _bootloader_dbl_tap must remain
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.

a7e3c74fed Autocreate files that prevent MacOS indexing of the CIRCUITPYTHON dive 
.. the price of this appears to be about 112 bytes of flash and 12
bytes of RAM, according to the stats printed during the build.

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)

c37ade9aeb Correct NO_TIMER index value for SAMD21. 
We check validity by ensuring it's lower than the total number of
timers. 0 is a terrible number for the NO_TIMER value because its
valid even though it shouldn't be.

8157248189 Move usb read finish into interrupt. 
Having the `active_read = false` in the background function left
a chance that a new_write occurs before active_read is set to false.

In that case, we'll read the appropriate data rather than write it
and never clear the active write.

Hopefully fixes #655.

2. Make NeoPixel timing deterministic by turning off caches during NeoPixel writes.
3. Incorporate asf4 updates:
  a. async USART driver
  b. bringing Atmel START configuration closer to what we use
  c. Clock initialization order now specified by CIRCUITPY_GCLK_INIT_1ST and _LAST.
4. supervisor/port.c: Move commented-out clock-test pin setting to correct location.

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.

01443a9619 Make chosen features consistent across all boards and ports atmel-samd, esp8266, and nrf. 
1. Turn off MICROPY_CPYTHON_COMPAT, which includes a number of minor CPython compatibility features,
most of which have workarounds, but uses up significant flash.
2. Turn on MICROPY_PY_SYS_MAXSIZE, which implements sys.maxsize.
3. Turn on MICROPY_CAN_OVERRIDE_BUILTINS, which implements "_" as the most recent value in the REPL,
and also enables redefining builtins.

Also, fixed pin mappings for rev B Metro M4:
swap PA12 and PA13 on SPI 2x3 header
swap A3 and A5

Comment out all frozen modules in CPX again to make room while waiting
for SPI flash.

971bd7e9a6 atmel-samd: Improve MSC reliability. 
* Be more liberal with critical sections to ensure ordering.
* Correct usb_busy so that it is busy when no errors occur on
  transfer. I believe it worked before because it would be false
  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.
