This needs to be re-generated on every .mpy version increase, so might as

Instead of being an explicit field, it's now a slot like all the other
methods.
This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.
Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
The goal here is to remove a slot (making way to turn make_new into a slot)
as well as reduce code size by the ~40 references to mp_identity_getiter
and mp_stream_unbuffered_iter.
This introduces two new type flags:
- MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the
type is "iternext", and should use the identity getiter.
- MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer
to a mp_getiter_iternext_custom_t instance, which then defines both
getiter and iternext.
And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This
means that the type should use the identity getiter, and
mp_stream_unbuffered_iter as iternext.
Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give
the default case where "iter" is "getiter".

This will always have the maximum/minimum size of a mp_obj_type_t
representation and can be used as a member in other structs.
Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
The buffer protocol type only has a single member, and this existing layout
creates problems for the upcoming split/slot-index mp_obj_type_t layout
optimisations.
If we need to make the buffer protocol more sophisticated in the future
either we can rely on the mp_obj_type_t optimisations to just add
additional slots to mp_obj_type_t or re-visit the buffer protocol then.
This change is a no-op in terms of generated code.

In that case, no Pin will be configured for the CS signal, even if it is
internally still generated. That setting allows to use any pin for CS,
which then must be controlled by the Python script.
Also make the default cs=-1 to match other ports (software CS).
The new teensy loader keeps the file system under certain conditions:
- The file size is properly set in the file header.
- The header version is 4.3
These changes are implemented here, requiring a backport of
fsl_flexspi_nor_boot.c. There is still a problem with the command line
version of the teensy loader, which fails on the first attempt. At the
second attempt it works. The GUI version of the teensy loader is fine.

Since L4 HAL version 1.17.0, HAL_TIM_IC_Start_IT() checks whether specified
channel of timer is busy or not, which is the case if this function is
called more than once without first calling HAL_TIM_IC_Stop_IT(). The fix
in this commit is to call the stop function before calling start. The PWM
and OC modes have the same issue with the same fix.
Fixes issue #8732.
Prior to this commit, excuting this code:
i2c = I2C(1, I2C.CONTROLLER, dma=True)
i2c.send(data, addr=i2c_addr)
the call to i2c.send() does not return and the board needs a reset. This
code works when dma=False.
According to the specification, I2Cx_EV_IRQHandler should:
- Write DR to address when Start condition generated.
- Clear ADDR by reading SR2 after reading SR2 when address sent.
These processes are included in HAL_I2C_EV_IRQHandler(), however the
firmware size increses about 2KB if HAL_I2C_EV_IRQHandler is called. This
commit adds above processes to i2c_ev_irq_handler, and increases firmware
by less than 100 bytes.
Fixes issue #2643.
pyb.ADC(channel) checks whether specified channel is valid or have ADC

Although this driver and associated hardware can be used on any board, it
makes to only freeze it for PYB and PYBD boards. It can be easily copied
to any board if needed.

Changes in this commit:
- Manifest include's now use the directory path where possible (no longer
necessary to include the manifest.py file explicitly).
- Add manifest.py for all drivers and components that are referenced by
port/board manifests.
- Replace all uses of freeze() with package()/module(), except for port and
board modules.
- Use opt=3 everywhere, for consistency and to reduce code size.
- Use require() instead of include() for all micropython-lib references.
- Remove support for optional board-level manifest.py in mimxrt port, to
make it behave the same as other ports (the board must set
FROZEN_MANIFEST to a custom manifest.py, which can optionally include the
default, port-level manifest).
- Also reinstates modules that were accidentally removed from the esp8266

Previously the desired output type was specified. Now make the type part

saves code size due to smaller call-site.
This makes `mp_obj_new_str_type_from_vstr` a private function of objstr.c
(which is almost the only place where the output type isn't a compile-time
constant).

If mboot is built with support for packing (signing/encryption) it needs up
to 32KiB. So for simplicity increase the mboot region to 32KiB
unconditionally for WB55 boards (custom WB55 board configurations can still
provide their own linker scripts to override this).
It used to be 10 bit times, which is too short. The break state must be
longer than a regular character time, at least 13 bit times. This is now
implemented by reducing the baudrate while sending the "0". The break time
will now vary with data length and parity setting, but will at least be 15
bit times.
Tested with a GENERIC_SPIRAM, GENERIC_C3 and UM_TINYS2 board.
Set the channel with esp_wifi_set_channel(), which adds support for setting
the channel of the STA interface
Get the channel with esp_wifi_get_channel() which returns the actual wifi
channel of the radio, rather than the configured channel.
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).

It seems sometimes gcc with LTO will generate otherwise valid assembly
listings that cause 'as' to error out when generating DWARF debug info; see
https://sourceware.org/bugzilla/show_bug.cgi?id=29494
Therefore, don't enable -g by default if LTO is on.
Enabling LTO=1 DEBUG=1 is still possible but may result in random errors
at link time due to 'as' (the error in this case is "Error: unaligned
opcodes detected in executable segment", and the only other easy workaround
is CFLAGS+=-fno-jump-tables which may increase code size significantly).

Binaries built using the Make build system now no longer appear in the
working directory of the build, but rather in the build directory. Thus
some paths had to be adjusted.
In-the-field use of these FUS/WS firmware update scripts has exposed some
weak points, causing corrupted FUS/WS firmware to be flashed to the unit.
The problems are mostly caused with the ST GUI application, but sometimes
from un-recognised failures during bin file transfer to the WB55 prior to
running the rfcore_firmware.py script. Other failures were caused by
incorrect load addresses being used, again both from user error copying the
address from the HTML release notes to the GUI tool, but also from
similarly not updating the address correctly in rfcore_firmware.py
To guard against these errors and make it easier to prepare different
versions, this commit adds a few features to the rfcore firmware update
tools:
- When creating the bin file, automatically parse the release note in the
folder to get the correct address.
- Add a footer to the bin file containing the name, version, CRC, address
etc.
- Before flashing rfcore, check if the same version is already installed.
- Verify the CRC and obfuscation key before flashing bin.
- Log the name and version of file being flashed.
The ntptime module was previously only included in the ESP8266 port. This

- Same IMU chip.
- Similar external flash chip - 4MiB instead of 32MiB.
- 2 I/O ports instead of 6.
- No display - only status and battery LEDs.
- Different LED driver chip.
