I.e. for whichever SPI/I2C instance is PICO_DEFAULT_I2C, there's no need to
set MICROPY_HW_SPIn_SCK.
The only ones remaining are for the non-default instance.

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
capability but pyb.ADCAll().read_channel() does not.
This change adds checking whether specified channel is valid and throw
ValueError if channel is invalid. This is same as pyb.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.
Fixes issue #8056.

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
512k build in fbe9417b90.

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.

It has been about 8 years since support for this chip was added. Reasons
to remove it are:
- It is no longer easy to obtain this part.
- There are now many other options for WiFi.
- It's not a good use of developer time to maintain it.

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.
