At the Adafruit Metro M7 the pin GPIO_AD_13 is used for JTAG. Therefore
it is not configured for RTS at UART 2 and 3.

This commit:
- Finds a common set of board feature tags and maps existing features to
that reduced set.
- Removes some less-useful board feature tags.
- Ensures all MCUs are specified correctly.
- Ensures all boards have a vendor (and fixes some vendor names).
This is to make the downloads page show a less intimidating set of filters.

The asyncio module now has much better CPython compatibility and
deserves to be just called "asyncio".
This will avoid people having to write `from uasyncio import asyncio`.
Renames all files, and updates port manifests to use the new path. Also
renames the built-in _uasyncio to _asyncio.

This commit is necessary to make MicroPython work on this eval kit out of
the box, as the eval kit ships with the HyperFlash physically disconnected
from the bus (refer to the schematics or the user guide) and the QSPI
connected instead, but the fuses/board/pins are configured to boot from
internal flash (on FlexSPI2).
Note that enabling the HyperFlash is not trivial, as it requires soldering
and desoldering of many small footprint resistors and changing fuses.
This provides a standard interface to setting the global networking config
for all interfaces and interface types.
For ports that already use either a static hostname (mimxrt, rp2) they will
now use the configured value. The default is configured by the port
(or optionally the board).
For interfaces that previously supported .config(hostname), this is still
supported but now implemented using the global network.hostname.
Similarly, pyb.country and rp2.country are now deprecated, but the methods
still exist (and forward to network.hostname).
Because ESP32/ESP8266 do not use extmod/modnetwork.c they are not affected
by this commit.

The RT1176 has two cores, but the actual firmware supports only the CM7.
There are currently no good plans on how to use the CM4.
The actual MIMXRT1170_EVK board is on par with the existing MIMXRT boards,
with the following extensions:
- Use 64 MB RAM for the heap.
- Support both LAN interfaces as LAN(0) and LAN(1), with LAN(1)
being the 1GB interface.
The dual LAN port interface can eventually be adapted as well for the
RT1062 MCU.
This work was done in collaboration with @alphaFred.
This issue affected i.MX RT 1052, 1062 and 1064. It seems to be addressed
by Errata ERR006223, which also mentions i.MX RT101x and 102x, but these
devices worked well even without the change. As a side effect, the current
consumption at an idle REPL drops significantly with this fix.
Fixes issue #7235.
The new teensy loader keeps the file system under certain conditions:
- The file size is properly set in the file header.
- The header version is 4.3
These changes are implemented here, requiring a backport of
fsl_flexspi_nor_boot.c. There is still a problem with the command line
version of the teensy loader, which fails on the first attempt. At the
second attempt it works. The GUI version of the teensy loader is fine.
Changes in this commit:
- Manifest include's now use the directory path where possible (no longer
necessary to include the manifest.py file explicitly).
- Add manifest.py for all drivers and components that are referenced by
port/board manifests.
- Replace all uses of freeze() with package()/module(), except for port and
board modules.
- Use opt=3 everywhere, for consistency and to reduce code size.
- Use require() instead of include() for all micropython-lib references.
- Remove support for optional board-level manifest.py in mimxrt port, to
make it behave the same as other ports (the board must set
FROZEN_MANIFEST to a custom manifest.py, which can optionally include the
default, port-level manifest).
- Also reinstates modules that were accidentally removed from the esp8266
512k build in fbe9417b90.

Replaces preprocessor macro for SDRAM option from #ifdef to #if in order to
allow always setting the define `MICROPY_HW_SDRAM_AVAIL` just with the
appropriate value 0/1. This eliminates one `if` in the Makefile.
The nxp_driver v2.10 allows for/requires some changes to the code:
- Remove some part of pwm_backlog.*, which is provided by the lib now.
- Change eth.c: the newer versions have additional parameters of the
library versions.
- Change sdcard.c: use TransferBlocking instead of TransferNonblocking.
- Add some support for the MIMXRT1176 device.
- Set the clocks for UART, I2C, Timer.
- Integrate the I2S module and fix a rebase error.
- Use blocking transfer only for SPI. It's faster and interferes less with
other modules.
- Use the clock_config.c files of library v2.8.5. The mimxrt files keeps
the clock_config.c files from Verson 2.8.5. With clock_config.c from
v2.10, the boards do not work. Refactoring of the clock set-up is on the
to-do list.
- Enable expiry timers for UART, I2C and SPI, avoiding a stall in library
code.
- The clock_config.* files are moved from the board-specific directories to
the boards directory and given a MCU related name.
This commit adds support for machine.I2S on the mimxrt port. The I2S API
is consistent with the existing stm32, esp32, and rp2 implementations.
I2S features:
- controller transmit and controller receive
- 16-bit and 32-bit sample sizes
- mono and stereo formats
- sampling frequencies from 8kHz to 48kHz
- 3 modes of operation:
- blocking
- non-blocking with callback
- uasyncio
- configurable internal buffer
- optional MCK
Tested with the following development boards:
- MIMXRT1010_EVK, MIMXRT1015_EVK, MIMXRT1020_EVK, MIMXRT1050_EVK
- Teensy 4.0, Teensy 4.1
- Olimex RT1010
- Seeed ARCH MIX
Tested with the following I2S hardware peripherals:
- UDA1334
- GY-SPH0645LM4H
- WM8960 codec on board the MIMXRT boards and separate breakout board
- INMP441
- PCM5102
- SGTL5000 on the Teensy audio shield

OCOTP_Init() has been removed from mphalport.c. The library files are
missing for the MIMXRT1015, and for just reading the OCOTP the Init is not
required.
The board.json file is intentionally excluded, until the board will be
sold. But including it into the mimxrt series make it easier to keep
the build up-to-date.
Using the keyword argument cs=nnn in the constructor. The cs1
pin has to be defined in mpconfigboard.h.
Note: Only a few boards have the CS1 pin exposed to the connectors.
- Move the qspi_xxxx_flash_config.c files to hal.
It turned out that they are less board than flash type specific.
- Change to a common flexspi_flash_config.h header file.
UART 0 is attached to the Debug USB port. The settings are
115200 Baud, 8N1.
For MIMXRT1010_EVK this is identical to UART1. For the other boards,
this is an additional UART.
Frequency range 15Hz/18Hz to > 1 MHz, with decreasing resolution of the
duty cycle. The basic API is supported as documentated, except that
keyword parameters are accepted for both the instatiaton and the
PWM.init() call.
Extensions: support PWM for channel pairs. Channel pairs are declared by
supplying 2-element tuples for the pins. The two channels of a pair must
be the A/B channel of a FLEXPWM module. These form than a complementary
pair.
Additional supported keyword arguments:
- center=value Defines the center position of a pulse within the pulse
cycle. The align keyword is actually shortcut for center.
- sync=True|False: If set to True, the channels will be synchronized to a
submodule 0 channel, which has already to be enabled.
- align=PWM.MIDDLE | PMW.BEGIN | PWM.END. It defines, whether synchronized
channels are Center-Aligned or Edge-aligned. The channels must be either
complementary a channel pair or a group of synchronized channels. It may
as well be applied to a single channel, but withiout any benefit.
- invert= 0..3. Controls ouput inversion of the pins. Bit 0 controls the
first pin, bit 1 the second.
- deadtime=time_ns time of complementary channels for delaying the rising
slope.
- xor=0|1|2 xor causes the output of channel A and B to be xored. If
applied to a X channel, it shows the value oif A ^ B. If applied to an A
or B channel, both channel show the xored signal for xor=1. For xor=2,
the xored signal is split between channels A and B. See also the
Reference Manual, chapter about double pulses. The behavior of xor=2 can
also be achieved using the center method for locating a pulse within a
clock period.
The output is enabled for board pins only.
CPU pins may still be used for FLEXPWM, e.g. as sync source, but the signal
will not be routed to the output. That applies only to FLEXPWM pins. The
use of QTMR pins which are not board pins will be rejected.
As part of this commit, the _WFE() statement is removed from
ticks_delay_us64() to prevent PWM glitching during calls to sleep().
- Add board.md files for MIMXRT1060_EVK and MIMXRT1064_EVK warning about
their experimental state.
- Add separate deploy_teensy.md and deploy_mimxrt.md files.
The ARCH MIX board exposes the Ethernet Pins at it's connectors. Therefore
the software is configured for using a LAN8720 PHY device. Breakout boards
with the LAN8720 are easily available.
This will be used by https://micropython.org/download/ to generate the
full listing of boards and firmware files.
Optionally supports a board.md for additional customisation of the
download page, as well as deploy.md for flashing instructions.

By moving code to ITCM, like vm, gc, parse, runtime. The change affects
mostly the execution speed of MicroPython code. The speed is increased by
up to a factor of 6, especially for MCU with small cache.
This commit implements 10/100 Mbit Ethernet support in the mimxrt port.
The following boards are configured without ETH network:
- MIMXRT1010_EVK
- Teensy 4.0
The following boards are configured with ETH network:
- MIMXRT1020_EVK
- MIMXRT1050_EVK
- MIMXRT1060_EVK
- MIMXRT1064_EVK
- Teensy 4.1
Ethernet support tested with TEENSY 4.1, MIMRTX1020_EVK and MIMXRT1050_EVK.
Build tested with Teensy 4.0 and MIMXRT1010_EVK to be still working.
Compiles and builds properly for MIMXRT1060_EVK and MIMXRT1064_EVK, but not
tested lacking suitable boards.
Tested functions are:
- ping works bothway
- simple UDP transfer works bothway
- ntptime works
- the ftp server works
- secure socker works
- telnet and webrepl works
The MAC address is 0x02 plus 5 bytes from the manifacturing info field,
which can be considered as unique per device.
Some boards do not wire the RESET and INT pin of the PHY transceiver. For
operation, these are not required. If they are defined, they will be used.
