When you wish to use the valgrind memory analysis tool on micropython,
you can arrange to define MICROPY_DEBUG_VALGRIND to enable use of
special valgrind macros. For now, this only fixes `gc_get_ptr`
so that it never emits the diagnostic "Conditional jump or move depends
on uninitialised value(s)".

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().

The 72x40 OLED requires selecting the internal IREF, as opposed to the
default external IREF. This is an undocumented feature in the SSD1306
datasheet, but is present in the SSD1315 datasheet. It's possible the
72x40 OLED is actually using the newer SSD1315 controller. Sending the
IREF select command to SSD1306 displays has no effect on them, so it's
added to the init_display() instead of wrapping in an "if width = 72".
Also tested on a 128x64 OLED using the SSD1315 controller (smaller ribbon
cable) and the proposed change has no effect on the display, as the module
comes with the correct current limiting resistor. Internal and external
IREF work the same.
Fixes issue #7281.
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

above. ESP32S2 is not supported.

This commit fixes a problem with a race between cancellation of task A and
completion of task B, when A waits on B. If task B completes just before
task A is cancelled then the cancellation of A does not work. Instead,
the CancelledError meant to cancel A gets passed through to B (that's
expected behaviour) but B handles it as a "Task exception wasn't retrieved"
scenario, printing out such a message (this is because finished tasks point
their "coro" attribute to themselves to indicate they are done, and
implement the throw() method, but that method inadvertently catches the
CancelledError). The correct behaviour is for B to bounce that
CancelledError back out.
This bug is mainly seen when wait_for() is used, and in that context the
symptoms are:
- occurs when using wait_for(T, S), if the task T being waited on finishes
at exactly the same time as the wait-for timeout S expires
- task T will have run to completion
- the "Task exception wasn't retrieved message" is printed with
"<class 'CancelledError'>" as the error (ie no traceback)
- the wait_for(T, S) call never returns (it's never put back on the
uasyncio run queue) and all tasks waiting on this are blocked forever
from running
- uasyncio otherwise continues to function and other tasks continue to be
scheduled as normal
The fix here reworks the "waiting" attribute of Task to be called "state"
and uses it to indicate whether a task is: running and not awaited on,
running and awaited on, finished and not awaited on, or finished and
awaited on. This means the task does not need to point "coro" to itself to
indicate finished, and also allows removal of the throw() method.
A benefit of this is that "Task exception wasn't retrieved" messages can go
back to being able to print the name of the coroutine function.
Fixes issue #7386.

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

Using just the list of available ports, instead of a hard-coded list of
possible ports, means that all ports will be available for auto connection.
And the order that they will be attempted in will match what's printed by
"mpremote connect list" (and will be the same as before, trying ACMx before
USBx). Auto-connect will also now work on Mac, and will allow all COM
ports on Windows.

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.

- 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 fix prevents server.wait_closed() from raising an AttributeError when
trying to access server.task. This can happen if it is called immediately
after start_server().
This commit fixes the following problems converting to/from Python integers

- integers of 64 bits not working on 32 bits architectures
- unsigned returns were converted to signed Python integers
Fixes issue #7269.

Prior to this commit, cache flushing for ARM native code was done only in
the assembler code asm_thumb_end_pass()/asm_arm_end_pass(), at the last
pass of the assembler. But this misses flushing the cache when loading
native code from an .mpy file, ie in persistentcode.c.
The change here makes sure the cache is always flushed/cleaned/invalidated
when assigning native code on ARM architectures.
This problem was found running tests/micropython/import_mpy_native_gc.py on
the mimxrt port.
