Since commit e65d1e69e8 there is no longer an
io.FileIO class, so this option is no longer needed.
This option also controlled whether or not files supported being opened in
binary mode (eg 'rb'), and could, if disabled, lead to confusion as to why
opening a file in binary mode silently did the wrong thing (it would just
open in text mode if MICROPY_PY_IO_FILEIO was disabled).
The various VFS implementations (POSIX, FAT, LFS) were the only places
where enabling this option made a difference, and in almost all cases where
one of these filesystems were enabled, MICROPY_PY_IO_FILEIO was also
enabled. So it makes sense to just unconditionally enable this feature
(ability to open a file in binary mode) in all cases, and so just remove
this config option altogether. That makes configuration simpler and means
binary file support always exists (and opening a file in binary mode is
arguably more fundamental than opening in text mode, so if anything should
be configurable then it should be the ability to open in text mode).

These were added in Python 3.5.
Enabled via MICROPY_PY_BUILTINS_BYTES_HEX, and enabled by default for all
ports that currently have ubinascii.
Rework ubinascii to use the implementation of these methods.

For bare metal ARM & xtensa targets, passing -g will make the ELF file
larger but doesn't change the binary size. However, this means tools like
gdb, addr2line, etc can extract source-level information from the ELF.
Also standardise -ggdb to -g, these produce the exact same ELF file on
arm-none-eabi-gcc and will use DWARF format for all these ports.
Fixes:
- Should read `definitions` rather than `defintions`.
- Should read `resolution` rather than `resoultion`.
- Should read `inefficient` rather than `inefficent`.
- Should read `closed` rather than `closded`.

rp2: change tud_task() to tud_task_ext().
mimxrt: use lib/tinyusb/src/portable/chipidea/ci_hs/dcd_ci_hs.c instead of
lib/tinyusb/src/portable/nxp/transdimension/dcd_transdimension.c.
nrf: add a definition for the changed tud_task(). tud_task() is changed
to tud_task_ext(), and the #define for backward compatibility is in
src/device/usbd.h.
The items I know which are fixed with this version:
- Fix for the SAMD USB lock-up.
- Support the MIMXRT11XX series of MCUs.
- Fix a wrong pin definition for MIMXRT1050_EVKB.
Tested with the MIMXRT boards, rp2 Pico, SAMD boards, nrf board.
All ports that use mbedtls use the custom error messages in
mp_mbedtls_errors.c. This commit simplifies the build so that ports don't
need to explicitly add this file, it's now used by default when mbedtls is
enabled.

All in-tree uses of MICROPY_PORT_ROOT_POINTERS have been replaced with
MP_REGISTER_ROOT_POINTER(), so now we can remove both
MICROPY_PORT_ROOT_POINTERS and MICROPY_BOARD_ROOT_POINTERS from the code
and remaining config files.

This uses MP_REGISTER_ROOT_POINTER() to register mod_network_nic_list and
removes the same from all mpconfigport.h.

This uses MP_REGISTER_ROOT_POINTER() to register the readline_history root
pointer array used by shared/readline.c and removes the registration from
all mpconfigport.h files.
This also required adding a new MICROPY_READLINE_HISTORY_SIZE config option
since not all ports used the same sized array.

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.
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.

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.

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.
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.

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

This replaces occurences of
foo_t *foo = m_new_obj(foo_t);
foo->base.type = &foo_type;
with
foo_t *foo = mp_obj_malloc(foo_t, &foo_type);
Excludes any places where base is a sub-field or when new0/memset is used.

Changes in this commit:
- Fix USB CDC RX handling to not block when unprocessed. The fix follows
5873390226.
- Fix dupterm rx.
- Remove some obsolete lines.
This commit changes the method of waiting for SPI being not busy. Instead
of the FIFO size, the TransferBusyFlag is probed.
Also, raise an error if the transfer failed.
Changes in this commit:
- Start the RTC Timer at system boot. Otherwise time.time() will advance
only if an RTC() object was created.
- 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.
- Compensate an underflow in in timeutils_seconds_since_2000(), called by
time.time(), if the time is set to a pre-2000 date.
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

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.
That caused Ethernet to lock up at high data rates after ~200MByte data
average in a row. Tested now with data bursts up to 10 GByte and overall
data rates of ~8MByte/s at the Eth100 port.
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.
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.
