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.
This configuration is used by @ladyada and more often than it should
we've discovered late that a change introduced problems building
there.
By adding this to regular CI, hopefully we learn about and fix these
issues sooner rather than later.
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.

This is more or less a complete re-organization of the code.
* Use the actual byte size of the .bin file as the flash size,
as the algorithm for packing sections into the flash is complicated
* Match each section to a data region & find the high water mark in the
region
* Report on all the RAM regions, separately
Note that elftools is a requirement of esp-idf and so does not need to
be listed in our requirements.txt.
- modified pin type from pin_obj_t to machine_pin_obj_t

Re-commiting to fix local GitHub config issues. Adding CircuitPython support for the Arduino Nano RP2040 Connect. Have tested all digital and analog I/O, I2C, onboard LSM6DSOX. Uses the AT25SF128A external flash.
Leaving the bootloader from an IRQ (eg USB or I2C IRQ) will not work if
MBOOT_LEAVE_BOOTLOADER_VIA_RESET is disabled, ie if mboot jumps directly to
the application. This is because the CPU will still be in IRQ state when
the application starts and IRQs of lower priority will be blocked.
Fix this by setting a flag when the bootloader should finish, and exit the
bootloader always from the main (top level) thread.
This also improves the USB behaviour of mboot: it no longer abruptly
disconnects when the manifest command is sent.

RX and CTS are the input pins and pull-ups are enabled so they don't cause
a problem if left unconnected. But the output pins don't need a pull up
(they were originally all configured with pull up in commit
8f7491a109).
If needed, the pull-ups can be disabled in Python using machine.Pin after
the UART is constructed.
See issue #4369.

The DMA driver will turn off DMA if it hasn't been used for an amount of
time (to save power). The SDIO driver for cyw43 WLAN was not informing the
DMA driver that it was using DMA and there was a chance that the DMA would
turn off in the middle of an SDIO DMA transfer. The symptoms of this would
be printing of SDIO error messages and a failure to communicate with the
cyw43 WLAN module.
This commit fixes this issue by changing the SDIO driver to use the
dma_nohal_XXX API to initialise and start the DMA.

SysTick cannot wake the CPU from WFI/WFE so a hardware timer is needed to

This detects an overflowed flash partition, such as
```
1452105 bytes used, -10313 bytes free in flash firmware space out of 1441792 bytes (1408.0kB).
444428 bytes used, 1652724 bytes free in ram for stack and heap out of 2097152 bytes (2048.0kB).
```
on a metro esp32-s2 built with debugging.
This also removes the need to pin share because we don't use the
status LED while user code is running.
The status flashes fallback to the HW_STATUS LED if no RGB LED is
present. Each status has a unique blink pattern as well.
One caveat is the REPL state. In order to not pin share, we set the
RGB color once. PWM and single color will be shutoff immediately but
DotStars and NeoPixels will hold the color until the user overrides
it.
Fixes#4133
A board can now customise mboot with:
- MBOOT_LED1, MBOOT_LED2, MBOOT_LED3, MBOOT_LED4: if it needs to have
different LEDs for mboot compared to the application
- MBOOT_BOARD_LED_INIT: if it needs a fully customised LED init function
- MBOOT_BOARD_LED_STATE: if it needs a fully customised LED state-setting
function
- MBOOT_BOARD_GET_RESET_MODE: if it needs a fully customised function to
get the reset mode
With full customisation, the only requirement is a single LED to show the
status of the bootloader (idle, erasing, flashing, etc), which can be
configured to do nothing if needed.

It is enabled by default to get the standard behaviour of doing a reset
after it is finished, but can be disabled by a board to jump straight to
the application (likely the board needs to use MBOOT_BOARD_CLEANUP to make
this work).
The application is passed a reset mode of BOARDCTRL_RESET_MODE_BOOTLOADER
if the bootloader was active and entered via a jump.
Signed-off-by: Damien George <damien@micropython.org>
This new logic is equivalent to the old logic when the only possibilities
for reset_mode are NORMAL, SAFE_MODE and FILESYSTEM, which is the standard
case. But the new logic also allows other reset_mode values (eg
BOOTLOADER) to run boot.py and main.py.

When disabled the bootloader is entered via a direct jump. When enabled
the bootloader is entered via a system reset then a jump. It's enabled by
default to retain the existing behaviour, which is the recommended way.

As MicroDev1 pointed out the problem is a divide by zero when calculating the duty cycle.
Maybe need to check again in `common_hal_pwmio_pwmout_set_frequency()`.
FeatherS2 crashes if you set the PWMOut frequency to 0.
This change will raise `ValueError: Invalid PWM frequency` if the requested frequency is 0.

The number shown in the USB id is now the same as that returned by
machine.unique_id(). All 8 bytes are inserted as hex into the USB id. A

After discussing with danh, I noticed that `a/**/b` would not match `a/b`.
After correcting this and re-running "pre-commit run --all", additional
files were reindented, including the codeformat script itself.
In #4683, tannewt noticed that uncrustify was not running on some
file in common-hal.
I investigated and found that it was not being run on a bunch of paths.
Rather than make incremental changes, I rewrote list_files to work
bsaed on regular expressions; these regular expressions are created from
the same git-style glob patterns.
I spot-checked some specific filenames after this change, and all looks good:
```
$ python3 tools/codeformat.py -v --dry-run tests/basics/int_small.py ports/raspberrypi/common-hal/pulseio/PulseIn.c extmod/virtpin.c tests/thread/thread_exit1.py ports/raspberrypi/background.h extmod/re1.5/recursiveloop.c

black --fast --line-length=99 -v tests/thread/thread_exit1.py
```
recursiveloop and int_small are excluded, while PulseIn, virtpin,
and background are included.
Testing running from a subdirectory (not _specifically_ supported though):
```
(cd ports && python3 ../tools/codeformat.py -v --dry-run raspberrypi/common-hal/pulseio/PulseIn.c ../extmod/virtpin.c)
../tools/codeformat.py -v --dry-run raspberrypi/common-hal/pulseio/PulseIn.c ../extmod/virtpin.c
uncrustify -c /home/jepler/src/circuitpython/tools/uncrustify.cfg -lC --no-backup ../extmod/virtpin.c raspberrypi/common-hal/pulseio/PulseIn.
```
As a side-effect, a bunch more files are re-formatted now. :-P

Commit 1e297c8898 introduced a bug where the
very first reset-mode state on the LEDs was not shown, because prior to
that commit the first reset-mode state was the same as the initial LED

setting this initial LED state.

This adds support for making static (ie not on the Python GC heap) soft
timers. This can be useful for a board to define a custom background
handler, or eventually for BLE/network processing to use instead of systick
slots; it will be more efficient using soft timer for this.
The main issue with using the existing code for static soft timers is that
it would combine heap allocated and statically allocated soft_timer_entry_t
instances in the same pairing-heap data structure. This would prevent the
GC from tracing some of the heap allocated entries (because the GC won't
follow pointers outside the heap).
This commit makes it so that soft timer entries are explicitly marked,
instead of relying on implicit marking by having the root of the pairing
heap in the root pointer section. Also, on soft reset only the heap-
allocated soft timers are deleted from the pairing heap, leaving the
statically allocated ones.
