Philipp Ebensberger b1aec393b1 mimxrt/Makefile: Modify handling of SDRAM option.
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.

David Lechner c118b5d0e4 extmod/extmod.mk: Separate out extmod file list from py.mk to extmod.mk.
This separates extmod source files from `py.mk`.  Previously, `py.mk`
assumed that every consumer of the py/ directory also wanted to include
extmod/.  However, this is not the case.  For example, building mpy-cross
uses py/ but doesn't need extmod/.

This commit moves all extmod-specific items from `py.mk` to `extmod.mk` and
explicitly includes `extmod.mk` in ports that use it.

Damien George f5769698e5 extmod/modlwip: Clean up inclusion of modlwip in build process.
The following changes are made:

- Guard entire file with MICROPY_PY_LWIP, so it can be included in the
  build while still being disabled (for consistency with other extmod
  modules).

- Add modlwip.c to list of all extmod source in py/py.mk and
  extmod/extmod.cmake so all ports can easily use it.

- Move generic modlwip GIT_SUBMODULES build configuration code from
  ports/rp2/CMakeLists.txt to extmod/extmod.cmake, so it can be reused by
  other ports.

- Remove now unnecessary inclusion of modlwip.c in EXTMOD_SRC_C in esp8266
  port, and in SRC_QSTR in mimxrt port.

robert-hh a0432ed9cb mimxrt: Update port to work with new nxp_driver v2.10.
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.

Damien George efe23aca71 all: Remove third argument to MP_REGISTER_MODULE.
It's no longer needed because this macro is now processed after
preprocessing the source code via cpp (in the qstr extraction stage), which
means unused MP_REGISTER_MODULE's are filtered out by the preprocessor.

Damien George 6e71cde6aa ports: Use default VFS config for import_stat and builtin_open.
For ports with MICROPY_VFS and MICROPY_PY_IO enabled their configuration
can now be simplified to use the defaults for mp_import_stat and
mp_builtin_open.

This commit makes no functional change, except for the following minor
points:
- the built-in "open" is removed from the minimal port (it previously did
  nothing)
- the duplicate built-in "input" is removed from the esp32 port
- qemu-arm now delegates to VFS import/open

- Set the time to a more recent date than Jan 1, 1970, if not set.  That is
  2013/10/14, 19:53:11, MicroPython's first commit.

MikeTeachman 1f6cb8f047 mixmrt/machine_i2s: Add I2S protocol support.

- 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

robert-hh e0b97013d0 mimxrt/hal/pwm_backport: Make PWM symmetric, and round division calcs.
Ensure the symmetry of PWM: the duty rate of X and Q channels was not 50%,
when it should have been.  That is evident at high frequencies, like 15Mhz
or 37.5 MHz.  At low frequencies the deviation mattered less.  The A/B
channels were fine.

Also round up or down non-integer division factors. Before, always the
floor value was used.

robert-hh b0d460cd7d mimxrt/eth: Fix an Ethernet transmit error.
Sometimes frames could not be sent immediately because the controller was
still busy with previous frames.  Then, an error was returned to lwip.
This fix adds a limited number of retries for this busy state, waiting
100µs before the next attempt.  Typically the transmit succeeds now at the
second attempt.

Second change: Reset the controller for a clean state after soft reset.

robert-hh 1dc366f901 mimxrt: Replace Pin-config constants by a function call.
The Pin config setting by IOMUXC_SetPinConfig() is supplied by a

for supporting the MIMXRT117x family, the constant bit pattern is
replaced by a function call, such that the bit pattern is created
at a single place. The code for this functions was taken from
machine_pin.c.
