Previously the desired output type was specified. Now make the type part
of the function name. Because this function is used in a few places this
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).
This saves ~140 bytes on PYBV11.

Not safe to use mp_hal_delay_ms before boot if threading is enabled,
because threading will not have been initialised, and
MICROPY_EVENT_POLL_HOOK assumes threading is initialised.
HAL_Delay doesn't call MICROPY_EVENT_POLL_HOOK, but is still
power-efficient like mp_hal_delay_ms (unlike mp_hal_delay_us).

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).

stty can provide the current terminal settings, so that they can be
stored in a shell variable and restored after running the firmware. This
avoids the complete "blanking" of the terminal, and thus also removes the
need for the sleep call.
The run target now references the firmware file using the BUILD variable
instead of using the hard coded "build/" path.
The executable now lives in the build directory, and since the build

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
commit factors that module out into the extmod directory, makes it support
different epochs, and includes it in the rp2 port.
This adds support for the LEGO Hub No. 7, aka LEGO Technic Small hub, aka
LEGO SPIKE Essential hub. This board is largely similar to Hub No. 6:
- Same MCU (STM32F413 - different packaging with fewer pins).
- Same Bluetooth chip (TI CC2564).
- 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.
- Only 1 button which is also the power button.

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.
