# Define an equivalent for MICROPY_LONGINT_IMPL, to pass to $(MPY-TOOL) in py/mkrules.mk
# $(MPY-TOOL) needs to know what kind of longint to use (if any) to freeze long integers.
# This should correspond to the MICROPY_LONGINT_IMPL definition in mpconfigport.h.

Move atmel-samd to tinyusb and support nRF flash. This started while adding USB MIDI support (and descriptor support is in this change.) When seeing that I'd have to implement the MIDI class logic twice, once for atmel-samd and once for nrf, I decided to refactor the USB stack so its shared across ports. This has led to a number of changes that remove items from the ports folder and move them into supervisor. Furthermore, we had external SPI flash support for nrf pending so I factored out the connection between the usb stack and the flash API as well. This PR also includes the QSPI support for nRF.

ports/nrf: Implement audioio.AudioOut using PWM This implements AudioOut, with known caveats: * pause/resume are not yet implemented (this is just a bug) * at best, the sample fidelity is 8 bits (this is a hardware limitation) Testing performed: My test system is a Particle Xenon with a PAM8302 op-amp https://www.adafruit.com/product/2130 and 8-ohm speaker. There's no analog filtering between the Xenon's PWM pin and the "A+" input of the amplifier; the "A-" pin is disconnected. It is powered from VUSB. I used pin D4, which is *NOT* listed as a low-speed-only pin, but the code does NOT switch the pin to high drive. This is related to an open issue for general inability to set drive level for pins being used by a "special function" on nrf: https://github.com/adafruit/circuitpython/issues/1270 Nothing about the code I've written should limit the usable pins. All samples I played were 16-bit, generally monophonic at 11025Hz and 22050Hz from the Debian LibreOffice package.

# CircuitPython doesn't yet support NFC so force the NFC antenna pins to be GPIO.
# See https://github.com/adafruit/circuitpython/issues/1300
# Defined here because system_nrf52840.c doesn't #include any of our own include files.
