robert-hh 76cf98c35b samd/mcu: Implement a hardware seed for the SAMD21 random module.
By using the phase jitter between the DFLL48M clock and the FDPLL96M clock.
Even if both use the same reference source, they have a different jitter.
SysTick is driven by FDPLL96M, the us counter by DFLL48M.  As a random
source, the us counter is read out on every SysTick and the value is used
to accumulate a simple multiply, add and xor register.  According to tests
it creates about 30 bit random bit-flips per second.  That mechanism will
pass quite a few RNG tests, has a suitable frequency distribution and
serves better than just the time after boot to seed the PRNG.

robert-hh 7e0b1bc95d samd/mcu: Use the FDPLL96M clock for the SAMD21 CPU.
Allowing to increase the clock a little bit to 54Mhz.  Not much of a gain,
but useful for generating a RNG entropy source from the jitter between
DFLL48M and FDPLL96M.

were only shown in the schematics.

Also remove any reference to LED_.  This is just a text change, no
functional change.

Damien George c6140ad0d4 rp2/mpconfigport: Enable os.dupterm and hashlib.sha1 on all boards.
This further aligns the features available on Pico and Pico W boards.

os.dupterm is generally useful, but can still be disabled by a board if
needed.  hashlib.sha1 requires mbedtls for the implementation, but that's
always available (due to ucryptolib's requirements).  The entire hashlib
module can still be disabled by an individual board if needed.

robert-hh de1f1dd164 shared/runtime/softtimer: Use consistently the same clock source.
Before, both uwTick and mp_hal_ticks_ms() were used as clock source.  That
assumes, that these two are synchronous and start with the same value,
which may be not the case for all ports.  If the lag between uwTick and
mp_hal_ticks_ms() is larger than the timer interval, the timer would either
rush up until the times are synchronous, or not start until uwTick wraps
over.

As suggested by @dpgeorge, MICROPY_SOFT_TIMER_TICKS_MS is now used in
softtimer.c, which has to be defined in a port's mpconfigport.h with
the variable that holds the SysTick counter.

Note that it's not possible to switch everything in softtimer.c to use
mp_hal_ticks_ms() because the logic in SysTick_Handler that schedules
soft_timer_handler() uses (eg on mimxrt) the uwTick variable directly
(named systick_ms there), and mp_hal_ticks_ms() uses a different source
timer.  Thus it is made fully configurable.

Damien George 0afe60b876 rp2/rp2_pio: Track use of PIO resources and free them on soft reset.
Prior to this commit, on Pico W (where the CYW43 driver is enabled) the PIO
instruction memory was not released on soft reset, so using PIO after a
soft reset would eventually (after a few soft resets) lead to ENOMEM when
allocating a PIO program.

This commit fixes that by tracking the use of PIO memory by this module and
freeing it on soft reset.

Similarly, use of the state machines themselves are tracked and released on
soft reset.

David Lechner 3446d440f6 shared/runtime/gchelper: Drop cpu directive from ARM asm helpers.
This drops the `.cpu` directive from the ARM gchelper_*.s files.  Having
this directive breaks the linker when targeting older CPUs (e.g. `-mthumb
-mthumb-interwork` for `-mcpu=arm7tdmi`).  The actual target CPU should be
determined by the compiler options.

The exact CPU doesn't actually matter, but rather the supported assembly
instruction set.  So the files are renamed to *_thumb1.s and *thumb2.s to
indicate the instruction set support instead of the CPU support.

Damien Tournoud e982c1d8de esp32/network_lan: Add support for SPI-based ethernet chips.
Add support for various SPI-based ethernet chips (W5500, KSZ8851SNL,
DM9051) to the ESP32 port.  This leverages the existing support in ESP-IDF
for these chips -- which configures these chips in "MAC raw" mode -- and
the existing support for network.LAN in the ESP32 port.  In particular,
this doesn't leverage the wiznet5k support that is used on the rp2 and
stm32 ports (because that's for native use of lwIP).

Tested on the POE Featherwing (with the SJIRQ solder jumper bridged) and a
ESP32-S3 feather.

A note about the interrupt pin: The W5500 implementation within ESP-IDF
relies on hardware interrupt, and requires the interrupt pin from the W5500
to be wired to a GPIO.  This is not the case by default on the Adafruit
Ethernet FeatherWing, which makes it not directly compatible with this
implementation.

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.

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.

Jim Mussared 5f8f32f917 extmod/modnetwork: Use a type protocol to implement NIC functions.
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.

This affects the WizNet (in non-LWIP mode) and Nina NIC drivers.

robert-hh 564945a2a0 nrf/boards/seeed_xiao_nrf52: Add defn for Seeed XIAO NRF52840 Sense.
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.

it is much simpler and essentially the same to just use

The only difference is that tud_cdc_n_connected() only checks for DTR,

yn386 65d82066a8 stm32/pyb_i2c: Fix failing pyb.I2C(dma=True) after receiving 1 byte.
Excuting the code:

    i2c = I2C(1, I2C.CONTROLLER, dma=True)
    tmp = i2c.recv(1, i2c_addr)
    recv_data = bytearray(56)
    i2c.recv(recv_data, i2c_addr)

The second i2c.recv() fails with OSError: [Errno 110] ETIMEDOUT.  When
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.

  being the 1GB interface.

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

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.

- Max GPIO_NUM_MAX is 49 for IDF_TARGET_ESP32S3.

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

    PD0..PD31: 96..127

Pins can be denoted by the GPIO port number, the name as defined in
pins.csv or a string in the form Pxnn, like "PA16" or "PD03".

The pins.c and pins.h files are now obsolete.  The pin objects are part of
the AF table.

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.

This removes the difference in the time.ticks_us() range between SAMD21 and

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).

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.

    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)

is required after each CPU freq change to have ticks_ms run at the proper
rate.

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).

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.

This makes it so that all a port needs to do is set the relevant variables
and "include extmod.mk" and doesn't need to worry about adding anything to

Make all extmod variables (src, flags, etc) private to extmod.mk.

Also move common/shared, extmod-related fragments (e.g. wiznet, cyw43,
bluetooth) into extmod.mk.

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
ticks_us() and the peripherals like PWM run at not synchronous clocks.

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.

robert-hh 5c7e93ec48 samd/machine_adc: Add the machine.ADC class.

- 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.

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".

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.

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.

robert-hh 8804993d0f esp8266/machine_uart: Implement uart.flush() and uart.txdone().
uart.flush()

flush() will wait until all characters but the last one have been sent.
It returns while the last character is sent. If needed, the calling
code has to add one character wait time. To avoid a permanent lock,
a timeout applies depending on the size of the FIFO and the baud rate.

ret = uart.txdone()

ret is True if no transfer is in progress. It returns already True when
the last byte of a transfer is sent.
ret is False otherwise.

Jim Mussared 8a0ee5a5c0 py/objstr: Split mp_obj_str_from_vstr into bytes/str versions.
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.

Damien George 1855df6361 stm32: Remove support for CC3000 WiFi driver.
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.

Jim Mussared 986ad6bf1d stm32/boardctrl: Use HAL_Delay instead of mp_hal_delay_ms.
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).

Adds a "query-variants" target to stm32/Makefile to allow the set of
possible variants to be queried.

Andrew Leech 923375380b stm32/boards: Increase mboot region to 32k for WB55 boards.
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).

robert-hh 13dceaa4ea esp32/machine_uart: Change sendbreak time to be at least 15 bit times.
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.

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).
