Commit 0abf6f830c removed _boot.py from the
manifest for the GENERIC_512K board because the build does not include a
filesystem. But the main code expects _boot.py to be there and prints an
error if it's not. So add a custom _boot.py, which just sets the
gc.threshold().

This adds a wlan.config(reconnects=N) option to set the number of reconnect
attempts that will be made if the WLAN connection goes down. The default
is N=-1 (infinite retries, current behavior). Setting
wlan.config(reconnects=0) will disable the reconnect attempts.
A nice side effect of reconnects=0 is that wlan.status() will report the
disconnect reason now. See related issue #5326.
Ethernet-PHYs from ESP-IDF (LAN8720, IP101, RTL8201, DP83848) are now
supported in IDF v4.1 and above. PHY_KSZ8041 is only for ESP-IDF 4.3 and
above. ESP32S2 is not supported.

The implementation uses the LPUARTx devices. Up to 8 UARTs can be used,
given that the pins are accessible. E.g. 8 on Teensy 4.1, 5 on
MIMXRT1020_EVK.
For Tennsy 4.0 and 4.1 the UART numbers are as printed on the pinout 1..N.
The MIMXRT10xx-EVK boards have only one UART named, which gets the number
1. All other UART are assigned to different Pins:
MIMXRT1010-EVK:
D0/D1 UART 1
D6/D7 UART 2
A0/D4 UART 3
MIMXRT1020-EVK:
D0/D1 UART 1
D6/D9 UART 2
D10/D12 UART 3
D14/D15 UART 4
A0/A1 UART 5
MIMXRT1050-EVK, MIMXRT1060-EVK, MIMXRT1064-EVK:
D0/D1 UART 1
D7/D6 UART 2
D8/D9 UART 3
A1/A0 UART 4
This fixes error: cast to smaller integer type 'int' from 'pthread_t'.
pthread_t is defined as long, not as int.

The rtc_set_datetime() from pico-sdk will validate the values in the
datetime_t structure and refuse to set the time if they aren't valid. It
makes sense to raise an exception if this happens instead of failing
silently which might be confusing (as an example, see:
https://github.com/micropython/micropython/pull/6928#issuecomment-860166044
).
The supplied value for microseconds in datetime() will be treated as a
starting value for the reported microseconds. Due to internal processing
in setting the time, there is an offset about 1 ms.
This change moves the datetime tuple format back to the one used by all the
other ports:
(year, month, day, weekday, hour, minute, second, microsecond)
Weekday is a number between 0 and 6, with 0 assigned to Monday. It has to
be provided when setting the RTC with datetime(), but will be ignored on
entry and calculated when needed.
The weekday() method was removed, since that is now again a part of the
datetime tuple.
The now() method was updated so it continues to return a tuple that matches
CPython's datetime module.
Initial support for machine.RTC on rp2 port. It only supports datetime()
method and nothing else. The method gets/returns a tuple of 8 items, just
like esp32 port, for example, but the usec parameter is ignored as the RP2
RTC only works up to seconds precision.
The Pico RTC isn't very useful as the time is lost during reset and there
seems to be no way to easily power up just the RTC clock with a low current
voltage, but still there seems to be use-cases for that, see issues #6831,
and a Thonny issue #1592. It was also requested for inclusion on v1.15
roadmap on #6832.

Changes introduced are:
- the application offset is now loaded from the partition table instead of
being hard-coded to 0x10000
- maximum size of all sections is computed using the partition table
- an error is generated if any section overflows its allocated space
- remaining bytes are printed for each section

This commit adds a few math functions to the source list in the Makefile,
and implements the log2f function, so that ulab can be compiled on the nrf
boards. It also addresses part of #5162.
This commit fixes the following problems converting to/from Python integers
and ffi types:
- integers of 8 and 16 bits not working on big endian
- integers of 64 bits not working on 32 bits architectures
- unsigned returns were converted to signed Python integers
Fixes issue #7269.
Currently only advertising and scanning are supported, using the ring
buffer for events (ie not synchronous events at this stage).

board).

Zephyr's default value for CONFIG_NET_SOCKETS_POSIX_NAMES was changed
from false to true between Zephyr v2.5.0 and v2.6.0. This caused
conflicts in MicroPython, which uses the zsock_ prefixed functions, so
disable it.

Initial version, using the LP RTC clock. It provides setting the date and
time with rtc.init() or rtc.datetime(), and reading the date and time with
rtc.datetime() or rtc.now(). The method weekday() reports the weekday of
the current date. It starts with 0 for Monday.
The tuple order for datetime() and now() matches the CPython sequence:
(year, month, day, hour, minute, second, microsecond, TZ). TZ is ignored
and reported as None. Microsecond is provided at a best effort.
If a battery is not supplied, the default boot date/time is 1970/1/1 0:0:0.
With a battery, the clock continues to run even when the board is not
powered. The clock is quite precise. If not, using rtc.calibration() may
help.
It supports three hardware timer channels based on the PIT timers of the
MIMXRT MCU. The timer id's are 0, 1 and 2. On soft reboot all active
timers will be stopped via finalisers.
This is required since the Teensy Halfkay loader attempts to erase all of
the flash but fails to do so, at least in my tests. Formatting brings it
back to a known state.
This commit adds full support for a filesystem on all boards, with a block
device object mimxrt.Flash() and uos.VfsLfs2 enabled.
Main changes are:
- Refactoring of linker scripts to accomodate reserved area for VFS. VFS
will take up most of the available flash. 1M is reserved for code. 9K is
reserved for flash configuration, interrupts, etc.
- Addition of _boot.py with filesystem init code, called from main.c.
- Definition of the mimxrt module with a Flash class in modmimxrt.[ch].
- Implementation of a flash driver class in mimxrt_flash.c. All flashing
related functions are stored in ITCM RAM.
- Addition of the uos module with filesystem functions.
- Implementation of uos.urandom() for the sake of completeness of the uos
module.
It uses sample code from CircuitPython supplied under MIT license, which
uses the NXP SDK example code.
Done in collaboration with Philipp Ebensberger aka @alphaFred who
contributed the essential part to enable writing to flash while code is
executing, among other things.
Adds support for NeoPixels on GPIO32 and GPIO33 on ESP32. Otherwise,
NeoPixels wired to GPIO32/33 wll silently fail without any hints to the
user.
With thanks to @robert-hh.
Fixes issue #7221.
ATOM is a very small ESP32 development board produced by M5Stack, with a
size of 24mm * 24mm, with peripherals such as WS2812, IR, button, MPU6886
(Only Matrix), and 8 GPIO extensions. It also has a plastic shell.
With GCC 11 there is now a warning about array bounds of OTP-mac, due to
the OTP being a literal address.

The 512k build does not have a filesystem so there is no reason to include
the filesystem-related modules. This commit provides a custom manifest.py
for this board which no longer includes: _boot.py, flashbdev.py,
inisetup.py, upip.py, upip_utarfile.py. This cuts the build down by about
9k of flash.
