iabdalkader 66e0cfc3b9 rp2/machine_pin: Refactor the machine.Pin class for external GPIO.
Handle externally controlled GPIO pins more generically, by removing all
CYW43-specific code from `machine_pin.c`, and adding hooks to initialise,
configure, read and write external pins.  This allows any driver for an
on-board module which controls GPIO pins (such as CYW43 or NINA), to
provide its own implementation of those hooks and work seamlessly with
`machine_pin.c`.

robert-hh 5890a17ae0 rp2/rp2_flash: Call MICROPY_EVENT_POLL_HOOK_FAST after reading flash.
To allow the USB to work in cases where there is a lot of filesystem
access, in particular on boot.

For example, registering of the USB CDC interface may fail if:
- the board file system is lfs2 (default), and
- sys.path contains entries for the local file system (default), and
- files are imported by boot.py or main.py from frozen bytecode of the file
  system (common) and the file system contains many files, like 100.

In that case the board is very busy with scanning LFS, and registering the
USB interface seems to time out.  This commit fixes this by allowing the
USB to make progress during filesystem reads.

Also switch existing MICROPY_EVENT_POLL_HOOK uses in this file to
MICROPY_EVENT_POLL_HOOK_FAST now that the latter macro exists.

Paul Grayson b208cf23e2 rp2/mphalport: Change order of pin operations to prevent glitches.
When switching from a special function like SPI to an input or output,
there was a brief period after the function was disabled but before the
pin's I/O state was configured, in which the state would be poorly defined.
This fixes the problem by switching off the special function after fully
configuring the I/O state.

Fixes #10226.

Felix Dörre 439298be15 rp2: Fix lightsleep to work with interrupts and cyw43 driver.
This commit prevents the device from "hanging" when using lightsleep while
the WiFi chip is active.

Whenever the WiFi chip wants to interrupt the microcontroller to notify it
for a new package, it sets the CYW43_PIN_WL_HOST_WAKE pin to high,
triggering an IRQ.  However, as polling the chip cannot happen in an
interrupt handler, it subsequently notifies the pendsv-service to do a poll
as soon as the interrupt handler ended.  In order to prevent a new
interrupt from happening immediately afterwards, even before the poll has
run, the IRQ handler disables interrupts from the pin.

The first problem occurs, when a WiFi package arrives while the main loop
is in cyw43-code.  In order to prevent concurrent access of the hardware,
the network code blocks pendsv from running again while entering lwIP code.

The same holds for direct cyw43 code (like changing the cyw43-gpios, i.e.
the LED on the Pico W).  While the pendsv is disabled, interrupts can still
occur to schedule a poll (and disable further interrupts), but it will not
run.  This can happen while the microcontroller is anywhere in rp2040 code.

In order to preserve power while waiting for cyw43 responses,
cyw43_configport.h defines CYW43_DO_IOCTL_WAIT and
CYW43_SDPCM_SEND_COMMON_WAIT to __WFI().  While this might work in most
cases, there are 2 edge cases where it fails:
- When an interrupt has already been received by the cyw43 stack, for
  example due to an incoming ethernet packet.
- When the interrupt from the cyw43 response comes before the
  microcontroller entered the __WFI() instruction.

When that happens, wfi will just block forever as no further interrupts are
received.  The only way to safely use wfi to wake up from an interrupt is
inside a critical section, as this delays interrupts until the wfi is
entered, possibly resuming immediately until interrupts are reenabled and
the interrupt handler is run.  Additionally this critical section needs to
check whether the interrupt has already been disabled and pendsv was
triggered, as in such a case, wfi can never be woken up, and needs to be
skipped, because there is already a package from the network chip waiting.
Note that this turns cyw43_yield into a nop (and thereby the cyw43-loops
into busy waits) from the second time onwards, as after the first call, a
pendsv request will definitely be pending.  More logic could be added, to
explicitly enable the interrupt in this case.

Regarding lightsleep, this code has a similar problem.  When an interrupt
occurs during lightsleep, the IRQ and pendsv handler and thereby poll are
run immediately, with the clocks still disabled, causing the SPI transfers
to fail.  If we don't want to add complex logic inside the IRQ handler we
need to protect the whole lightsleep procedure form interrupts with a
critical section, exiting out early if an interrupt is pending for whatever
reason.  Only then we can start to shut down clocks and only enable
interrupts when the system is ready again.  Other interrupt handlers might
also be happy, that they are only run when the system is fully operational.

Tested on a Pico W, calling machine.lightsleep() within an endless loop and
pinging from the outside.

This was previously implemented by adding additional members to the
mp_obj_type_t defined for each NIC, which is difficult to do cleanly with
the new object type slots mechanism. The way this works is also not
supported on GCC 8.x and below.

Instead replace it with the type protocol, which is a much simpler way of
achieving the same thing.

It keeps compatibility with the XIAO bootloader by:
- using Soft Device 7.3.0
- reserving 48k memory for the bootloader.

So on double reset a drive pops for uploading an uf2 image or a nrfutil zip
pkg file.  Instructions to create it from a hex file are included.  The
bootloader can as well be activated with the touch 1200 option of nrfutil.

The script download_ble_stack.sh has been adapted to get the version 7.3.0
soft device files.  It may have to be executed once before building.

The file system is set to 256k and the pin definitions are adapted.
Besides that, it has the common functionality and omissions.  The on-board
sensors and additional flash can be supported by Python scripts.

receiving greater than or equal to 2 bytes at first i2c.recv(), the second
i2c.recv() succeeds.  This issue does not occur without DMA.

Details of change: when executing I2C with DMA:

- Bit 11 of I2Cx_CR2 (DMA Request Enable) should be 1 to indicate that DMA
  transfer is enabled.  This bit is set after I2C event interrupt is
  enabled in HAL_I2C_Master_Transmit_DMA()/HAL_I2C_Master_Receive_DMA(), so
  DMA Request Enable bit might be 0 in IRQHandler.

- In case of data receive:
    - When only 1 byte receiption, clear I2Cx_CR1's bit 10 (ACK).
    - When only 2 byte receiption, clear I2Cx_CR1's bit 10 (ACK) and set
      bit 11 (POS).
    - When greater than or equal to 2 byte receiption, bit 12 of I2Cx_CR2
      (DMA Last Transfer) should set to generate NACK when DMA transfer
      completed.

Otherwise, the I2C bus may be busy after received data from peripheral.

robert-hh 5e990cc27f mimxrt: Add support for MIMXRT1176 MCUs, and MIMXRT1170_EVK board.
The RT1176 has two cores, but the actual firmware supports only the CM7.
There are currently no good plans on how to use the CM4.

The actual MIMXRT1170_EVK board is on par with the existing MIMXRT boards,
with the following extensions:
- Use 64 MB RAM for the heap.
- Support both LAN interfaces as LAN(0) and LAN(1), with LAN(1)
  being the 1GB interface.

The dual LAN port interface can eventually be adapted as well for the
RT1062 MCU.

This work was done in collaboration with @alphaFred.

Damien George 5987130afd webassembly/Makefile: Change compiler optimisation from O3 to Os.
Emscripten strongly advises the use of optimisation when compiling with
ASYNCIFY enabled.  Testing the difference betwen O3 and Os for various
configurations gives:

    flags                      firmware.wasm   micropython.js  perf
    -O3 -s ASYNCIFY            1342003          212845         0 (baseline)
    -O3 -s ASYNCIFY -s WASM=0        -         7064750         -30%
    -O3                         367131          196569         +140%
    -O3 -s WASM=0                    -         2818260         +30%
    -Os -s ASYNCIFY            1135450          213064         +40%
    -Os -s ASYNCIFY -s WASM=0        -         6239768         -30%
    -Os                         295028          196569         +180%
    -Os -s WASM=0                    -         2271358         +30%

The first row is prior to this commit.  The second and third columns show
firmware size (add them to get the total size).  The fourth column shows
the approximate change in performance compared to the baseline.  The
performance was measured using run-perfbench.py and the error was large, up
to 20%, although general trends in the change in performance could still be
seen.

In summary, using using Os instead of O3 makes it a little bit faster in
all cases, and smaller output (wasm/js) in all cases.

Mark Grosen 12f9948151 esp32/machine_i2c: Fix clocks and timeouts for ESP32-C3, ESP32-S3.
Each SoC family has its own clocks and timings/timeouts. For I2C, the
default source clock is either APB (ESP32, ESP32-S2) or XTAL (ESP32-S3,
ESP32-C3) as shown in the datasheets.  Since
machine_i2c.c/machine_hw_i2c_init() uses the default clk_flags (0), the
alternate low-power clock source is never selected in ESP-IDF
i2c.c/i2c_param_config().  There is not an API in i2c.c to get the source
clock frequency, so a compile-time value is used based on SoC family.

Also, the maximum timeout is different across the SoC families, so use the
I2C_LL_MAX_TIMEOUT constant to eliminate the warning from
i2c_set_timeout().

With these changes, the following results were obtained.  The I2C SCL
frequencies were measured with a Saleae logic analyzer.

ESP32 (TTGO T Dislay)
    I2C(0, scl=22, sda=21, freq=101781)  Measured: 100KHz
    I2C(0, scl=22, sda=21, freq=430107)  Measured: 400KHz
    I2C(0, scl=22, sda=21, freq=1212121) Measured: 941KHz

ESP32-S3 (TTGO T-QT)
    I2C(0, scl=34, sda=33, freq=111111)  Measured: 107KHz
    I2C(0, scl=34, sda=33, freq=444444)  Measured: 400KHz
    I2C(0, scl=34, sda=33, freq=1111111) Measured: 842KHz

ESP32-C3 (XIAO ESP32C3)
    I2C(0, scl=7, sda=6, freq=107816)  Measured: 103KHz
    I2C(0, scl=7, sda=6, freq=444444)  Measured: 380KHz
    I2C(0, scl=7, sda=6, freq=1176470) Measured: 800KHz

As result of a simplification, the code now supports using pin names or
numbers instead of pin objects for modules like UART, SPI, PWM, I2C, ADC,
pininfo.

robert-hh e33db80a59 samd/clock_config: Extend the SAMD51 us-counter to 60 bit.
This removes the difference in the time.ticks_us() range between SAMD21 and
SAMD51.

The function mp_hal_ticks_us_64() is added and used for:
- SAMD51's mp_hal_ticks_us and mp_hal_delay_us().
  For SAMD21, keep the previous methods, which are faster.
- mp_hal_ticks_ms() and mp_hal_tick_ms_64(), which saves some bytes
  and removes a potential race condition every 50 days.

Also set the us-counter for SAMD51 to 16 MHz for a faster reading of the
microsecond value.

Note: With SAMD51, mp_hal_ticks_us_64() has a 60 bit range only, which is
still a long time (~36000 years).
2022-10-25 23:26:14 +11:00
robert-hh fc9d66fac6 samd/machine_rtc: Add the machine.RTC class.
Methods implemented are:
- rtc.init(date)
- rtc.datetime([new_date])
- rtc.calibration(value)

The presence of this class can be controlled by MICROPY_PY_MACHINE_RTC.  If
the RTC module is used, the time module uses the RTC as well.

For boards without a 32kHz crystal, using RTC makes no sense, since it will
then use the ULP32K oscillator, which is not precise at all.  Therefore, it
will by default only be enabled for boards using a crystal, but can be
enabled in the respective mpconfigboard.h.
2022-10-25 23:20:09 +11:00
robert-hh be31fde012 samd/mcu: Make some settings in mpconfigmcu.h conditional.

robert-hh 2251cb774b samd/machine_uart: Implement uart.txdone() and uart.flush().
Using the stream method for uart.flush().

uart.txdone() returns True, if the uart not busy, False otherwise.

uart.flush() waits until all bytes have been transmitted or a timeout
triggers.  The timeout is determined by the buffer size and the baud rate.

Also fix two inconsistencies when not using txbuf:
- Report in ioctl as being writeable if there is room in the tx buffer,
  only if it is configured.
- Print the txbuf size if configured.

Instead of being hard-coded, and then it works for all MCUs.

That fits except for a Sparkfun SAMD51 Thing Plus (known) bug, which uses
192k - 4 as magic address.  Therefore, that address is set as well to avoid
a problem when this bug is fixed by Sparkfun.
2022-10-25 23:09:04 +11:00
robert-hh 03075a6839 samd/modmachine: Implement machine.lightsleep().
Which just sets the CPU clock to 200kHz and switches the peripheral clock
off.  There are two modes:

    machine.lightsleep(duration_ms)

and

    machine.lightsleep()

In any mode any configured pin.irq() event will terminate the sleep.

Current consumption in lightsleep for some boards:
- 1.5 - 2.5 mA when supplied trough an active USB
  (Seeed XIAO w/o power LED, Adafruit ItsyBitsy)
- 0.8 - 2 mA when supplied through Gnd/+5V (Vusb)
  (Seeed XIAO w/o power LED, Adafruit ItsyBitsy)
- < 1 mA for SAMD51 when supplied trough a battery connector
  (Sparkfun Thing SAMD51 plus)

Related change: move the calls to SysTick_Config() into set_cpu_freq().  It
is required after each CPU freq change to have ticks_ms run at the proper
rate.

robert-hh 1c32cec7f1 samd/clock_config: Support changing machine.freq() for SAMD21.
The range is 1MHz - 48 MHz.  Note that below 8 MHz there is no USB support.
The frequency will be set to an integer fraction of 48 MHz.  And after
changing the frequency, the peripherals like PWM, UART, I2C, SPI have to be
reconfigured.

Current consumption e.g. of the Seeed Xiao board at 1 MHz is about 1.5 mA,
mostly caused by the on-board LED (green LED with 1k resistor at 3.3V).
2022-10-25 22:40:16 +11:00
robert-hh edc3f3d0d3 samd/clock_config: Extend the range of machine.freq().
The value given for machine.freq(f) is extend to the range of 1_000_000 to
200_000_000.  Frequencies below 48 MHz will be forced to an integer
fraction of 48 MHz.  At frequencies below 8 MHz USB is switched off.  The
power consumption e.g. of ADAFRUIT_ITSYBITSY_M4_EXPRESS drops to about
1.5 mA at 1 MHz.

Since the peripheral frequency is dropped as well, timing e.g. of PWM,
UART, I2C and SPI is affected and frequency/baud rate has to set again
after a frequency change below 48 MHz.

Damien George 8874a09119 extmod/mbedtls: Enable elliptic curve DH and DSA cryptography.
This is necessary to access sites that only support these protocols.

The rp2 port already has ECDH enabled, so this just adds ECDSA there.  The
other ports now gain both ECDH and ECDSA.  The code size increase is:

- rp2 (PICO_W): +2916 bytes flash, +24 bytes BSS
- stm32 (PYBD_SF6): +20480 bytes flash, +32 bytes data, +48 bytes BSS
- mimxrt (TEENSY41): +20708 bytes flash, +32 bytes data, +48 bytes BSS
- unix (standard x86-64): +39344 executable, +1744 bytes data, +96 BSS

This is obviously a large increase in code size.  But there doesn't seem to
be any other option because without elliptic curve cryptography devices are
partially cut off from the internet.  For use cases that require small
firmware size, they'll need to build custom firmware with a custom mbedtls
config.

MICROPY_HW_DFLL_USB_SYNC: Effective only if DFLL48 does not run from the

If no USB is connected, it will fall back to open loop mode.  The DFLL48M
clock is then pretty precise, but with a higher clock jitter at SAMD51
devices.

MICROPY_HW_MCU_OSC32KULP: Effective only if the devics uses a crystal as
clock source.  Run the MCU clock from the ULP 32kHz oszillator instead of
the crystal.  This flag was added to cater for a interference problem of
the crystal and Neopixel/Debug pins at Adafruit FEATHER Mx boards, which
causes the board to crash.  Drawback: ticks_ms() and time.time() vs. than

2022-10-06 22:49:06 +11:00
robert-hh aa870708ac samd/machine_spi: Add the machine.SPI class.
Suported by both SAMD21 and SAMD51.  It follows the generic API, except for
the bits=nn option, which is not implemented (yet).
2022-10-06 22:48:44 +11:00
robert-hh b33f204529 samd/machine_uart: Add the machine.UART class.
All board pins that have UART's assigned can be used.  Baud rate range is
75 Baud to ~2 MBaud.

No flow control yet, and only RX is buffered.  TX buffer and flow control
may be added later for SAMD51 with its larger RAM and Flash.
2022-10-06 22:48:12 +11:00
robert-hh 7d281f6165 samd/modmachine: Add disable_irq(), enable_irq() and idle() to machine.
No specific features.
2022-10-06 22:47:52 +11:00
robert-hh 4b6f6ccf88 samd/machine_pin: Add pin.irq() to the machine.Pin class.
Its API conforms to the docs.  There are 16 IRQ channels available, which
will be used as assignable to the GPIO numbers.  In most cases, the irq
channel is GPIO_no % 16.
2022-10-06 22:46:53 +11:00
robert-hh a9eef1b276 samd/samd_isr: Rework the interrupt tables.
Changes are:
- Have two separate tables for SAM21 and SAMD51.
- Use a short table for SAMD21.
- Add a comment to each line telling what it's for, making further use
  easier.
- Add preliminary handlers/entries for PendSV, EIC and Sercom.  These will
  be replaced later when the respecitve modules are added.
2022-10-06 22:46:10 +11:00
robert-hh d693758ab2 samd/machine_pwm: Add the machine.PWM class.
Features are:
- 3 to 5 different frequency groups.
- Freq range of 1Hz - 24 MHz.
- Duty rate stays stable on freq change.

Keyword options to the PWM constructor:
- device=n Select a specific PWM device.  If no device is specified, a free
           device is chosen, if available at that pin.
- freq=nnnn
- duty_u16=nnnn
- duty_ns=nnnn
- invert=True/False Allowing two outputs on the same device/channel to have
                    complementary signals.

If both freq and duty are provided, PWM output will start immediately.

Pins at the same device have the same frequency.  If the PWM output number
exceeds the number of channels at the PWM device, the effctive channel_no
is output_no % channel_count.  So with a channel count of 4, output 7 is
assigned to channel 3.  Pins at a certain channel have the same frequency
and duty rate, but may be seperately inverted.
2022-10-06 22:42:55 +11:00
robert-hh 5c7e93ec48 samd/machine_adc: Add the machine.ADC class.
With the method read_u16().  Keyword arguments of the constructor are:
- bits=n    The resolution; default is 12.
- average=n The average of samples, which are taken and cumulated.  The
            default value is 16.  Averaging by hw is faster than averaging
            in code.

The ADC runs at a clock freq 1.5 MHz.  A single 12 bit conversion takes
8 microseconds.
2022-10-06 22:41:44 +11:00
robert-hh 6765d4bbd6 samd/pin_af: Add the pin af table and its helper functions.
The pin af table is a representation of the MUX table from the data sheet.
It provides information for each pin about the supported device functions.

That information is needed by pin.irq, machine.ADC, machine.PWM,
machine.UART, machine.SPI and machine.I2C.  For each of these, the table
tells for each pin, which device number, af number and pad number is
assigned.  Using the table gives a straight, uniform access to the
information, where the benefit outweights the size of the table, which is
not that large.

The tables are MCU-specific.  It is not required to tell for each board,
which and where each of the above devices is available.  That makes addding
boards easy.

Note: The information for DAC and I2S was not included, since it affects
only a few pins.
2022-10-06 22:39:17 +11:00
robert-hh 6c037af086 samd/boards: Create pin_af_table.c from pin_af_table_SAMDxx.csv files.

Changes in this commit are:
- Use mphal_xx functions whenever possible.
- Remove obsolete includes.
- Clean up traces of a non-functional pin.irq() from earlier builds.
  Pin.irq() will be added in further commits in a working manner.
2022-10-06 22:37:05 +11:00

specified by Atmel is 96_000_000 to 120_000_000.
2022-10-06 22:34:42 +11:00
robert-hh b4d29fd47a samd/clock_config: Set up the clock configuration.
Clock settings:
- GCLK0: 48 MHz (SAMD21) or 120 MHz(SAMD51).
- GCLK1: 32768 Hz for driving the PLL.
- GCLK2: 48 MHz for tzhe peripheral clock.
- GCLK3: 1 MHz (SAMD21) or 8 MHz (SAMD51) for the µs ticks timer.
- GCLK8: 1 kHz for WDT (SAMD21 only).

If a 32 kHz crystal is present, it will be used as clock source.  Otherwise
the DFLL48M in open-loop mode is used.

GCLK0 for SAM51 can be changed between 48 MHz and 200 MHz.  The specified
range is 96 MHz - 120 MHz.
2022-10-06 22:33:31 +11:00

- ADAFRUIT_FEATHER_M4_EXPRESS: SAMD51 with 32kHz crystal.
- ADAFRUIT_ITSYBITSY_M0_EXPRESS: SAMD21 without crystal.
- ADAFRUIT_ITSYBITSY_M4_EXPRESS: SAMD51 without crystal.

Jim Mussared 94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
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.

Jim Mussared 6da41b5900 py/obj: Merge getiter and iternext mp_obj_type_t slots.
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".

Jim Mussared fb2a57800a all: Simplify buffer protocol to just a "get buffer" callback.
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.

yn386 989b8c728b stm32/timer: Fix use of timer channel callback() method on L4 MCUs.
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.

yn386 da50827657 stm32/pyb_i2c: Fix pyb.I2C to work with dma=True on F4 MCUs.
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.

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

Damien George 8f4c108025 all: Remove MICROPY_PY_IO_FILEIO config option.
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).

Andrew Leech 6804b6f54f stm32/boards/NUCLEO_WB55: Add error handling to firmware update scripts.
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.

David Lechner 10f85fee18 stm32/boards/LEGO_HUB_NO7: Add LEGO Hub No. 7 board definition.
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.
- No speaker.

Some devices, such as the LightBlue BTLE app on iOS, try to use Bluetooth 5
when connecting to a device.  This means that they will send a
BLE_GAP_EVT_PHY_UPDATE_REQUEST message to shift to a new physical layer.
If this event isn't handled, LightBlue (and likely other Bluetooth 5.0
central devices) will try to connect and then fail, staying in
"Connecting..." state forever.  This message should be replied to with
sd_ble_gap_phy_update, as documented in
drivers/bluetooth/s140_nrf52_6.1.1/s140_nrf52_6.1.1_API/include/ble_gap.h.

David Lechner 093c4b6b26 unix/main: Restore tty settings on nlr_jump_fail().
Since nlr_jump_fail() exits the process, it can leave the terminal in raw
mode which means characters are not echoed.  Fix this by restoring the
original terminal mode.

Jim Mussared 662dc8602b rp2: Make atomic sections suspend the other core (if active).
When a flash write/erase is in progress, we need to ensure that the
other core cannot be using XIP.

This also implements MICROPY_BEGIN_ATOMIC_SECTION as a full mutex, which
is necessary as it's used to syncronise access to things like the scheduler
queue.

Jim Mussared daff597753 rp2: Run USB stack task exclusively from core 0.
The goal is to avoid a situation where core 1 is shut down while holding
the tinyusb spinlock, which could happen during soft reset if
mp_thread_deinit is called while core1 is running tud_task().

This also fixes a latent race where the two cores are competing to
decrement and compare `vm_hook_divisor` with no mem fence or atomic
protection -- only core0 will now do this.
