f254cfd3c4 stmhal: Rename mp_const_vcp_interrupt to mp_kbd_exception.
mp_kbd_exception is now considered the standard variable name to hold the
singleton KeyboardInterrupt exception.

This patch also moves the creation of this object from pyb_usb_init() to
main().

e8f2db7da3 py/runtime: Zero out fs_user_mount array in mp_init.
There's no need to force ports to copy-and-paste this initialisation
code.  If FSUSERMOUNT is enabled then this zeroing out must be done.

1b6d94bccd stmhal: Refactor to use extmod implementation of software SPI class.
This is a pure refactoring (and simplification) of code so that stmhal
uses the software SPI class provided in extmod, for the machine.SPI
implementation.

1eb3c66e91 extmod/machine_spi: Provide reusable software SPI class.

4c7d799b82 stmhal/uart: Add check that UART id is valid for the given board.
Previous to this patch trying to construct, but not init, a UART that
didn't exist on the target board would actually succeed.  Only when
initialising the UART would it then raise an exception that the UART does
not exist.

This patch adds an explicit check that the constructed UART does in fact
exist for the given board.

27a503f632 stmhal: Refactor UART configuration to use pin objects.
This follows the pattern of other peripherals (I2C, SPI) to specify the
pins using pin objects instead of a pair of GPIO port and pin number.  It
makes it easier to customise the UART pins for a particular board.

The constants MP_IOCTL_POLL_xxx, which were stmhal-specific, are moved
from stmhal/pybioctl.h (now deleted) to py/stream.h.  And they are renamed
to MP_STREAM_POLL_xxx to be consistent with other such constants.

All uses of these constants have been updated.

08bd7d1d31 stmhal/sdcard: Clean/invalidate cache before DMA transfers with SD card.
Add 2 macros in mphalport.h that clean and invalidate data caches only on
STM32F7 MCUs.  They are needed to ensure the cache coherency before/after
DMA transferts.

* MP_HAL_CLEANINVALIDATE_DCACHE cleans and invalidate the data cache. It
  must be called before starting a DMA transfer from the peripheral to the
  RAM memory.

* MP_HAL_CLEAN_DCACHE cleans the data cache.  It must be called before
  starting a DMA transfert from the RAM memory to the peripheral.

These macros are called in sdcard.c, before reading from and writing to
the SDCard, when DMA is used.

c19a395cac stmhal/adc: Make channel "16" always map to the temperature sensor.
The temperature sensor on F4 and F7 MCUs is mostly, but not always, on
channel 16.  To retain compatibility across all these MCUs this patch
maps the user-facing channel 16 to the internal temperature sensor.

029f215ead stmhal/adc: Add "mask" selection parameter to pyb.ADCAll constructor.
The "mask" parameter is used to select which pins the ADCAll constructor

which is backwards compatible with previous behaviour.

3053748987 stmhal: Add beginnings of port-specific machine.I2C implementation.
This allows one to construct an I2C object using ids that are specific
to the stmhal port, eg machine.I2C('X').  Right now the implementation
of I2C uses software I2C but the idea is to just change the C-level I2C
protocol functions to hardware implementations later on.

7604de3fc2 stmhal/can: clear FIFO flags in IRQ handler
HAL Driver before v1.4.2 had a bug which caused clearing all pending
flags in MSR, TSR, RF0R and RF1R instead of only the requested one.

This is why micropython got away without explicitly clearing flags
in IRQ handler.

dc1ac5dc3a stmhal/dma: mark DMA sate as READY even if HAL_DMA_Init is skipped

63ca7a211a stmhal/dma: precalculate register base and bitshift on handle init
Current version of HAL drivers optimize IRQ handler by using precalculated
DMA register address and stream bitshift instead of calculating it on every interrupt.

Since we skip call to `HAL_DMA_Init` on reused DMA, fields StreamBaseAddress and StreamIndex
of DMA handle are not initialized and thus leads to SegFault in `DMA_IRQHandler`.

HAL_DMA_Init is a big routine and we do not need to call it on each use of DMA
(ex.: series of I2C operations) and DMA_CalcBaseAndBitshift is really small and
releasing it increases code size by only 8 bytes.

59a1201da9 all: Remove readall() method, which is equivalent to read() w/o args.

74fb5d6932 stmhal/i2c: Reset the I2C peripheral if there was an error on the bus.
If an I2C send/recv fails then the peripheral is now checked to see if
it's in a "stuck" state waiting for the stop bit, and if so then it is
reset so that the next I2C transaction can proceed.

This patch also de-inits the I2C peripheral in the init() method, before
init'ing it again.

c4e58eaa98 stmhal/i2c: Add option to I2C to enable/disable use of DMA transfers.
New keyword option in constructor and init() method is "dma=<bool>".

not handle I2C bus errors very well (eg if slave device doesn't ACK or
NACK correctly during a transfer).

e6da6a720f stmhal/dma: De-init the DMA peripheral properly before initialising.

it is always called to make sure the DMA is properly reset.

1f433c719b stmhal: Fix linker map for STM32L476 chips.
In particular, this makes the L4 .isr_vector section 16K in size so it's
the same as the F4/F7 MCUs.  The patch also moves the L4 filesystem to
the end of flash, which allows for 512K filesystem on the 1Mb devices
like the STM32L476DISC.

b932b2dd1f extmod/machine_spi: Use delay_half, not baudrate, for internal timing.
The delay_half parameter must be specified by the port to set up the
timing of the software SPI.  This allows the port to adjust the timing
value to better suit its timing characteristics, as well as provide a
more accurate printing of the baudrate.

It's simpler to just default to always using software SPI if no specific

hardware peripheral id as the first parameter to the SPI constructor.

5bb28c7f10 extmod/machine_spi: Simplify SPI xfer function to only take one buf len.
There is no need to take src_len and dest_len arguments.  The case of
reading-only with a single output byte (originally src_len=1, dest_len>1)
is now handled by using the output buffer as the input buffer, and using
memset to fill the output byte into this buffer.  This simplifies the
implementations of the spi_transfer protocol function.

If a user tries to call `swint()` while interrupt is disabled the flag in
SWIER is set but the interrupt is not triggered and therefore the SWIER bit
is not cleared.  When the interrupt is again enabled the next call to
`swint()` won't trigger the IRQ because a 0 to 1 transition will not occur.

lcd.lcd_out() to deassert CS after each transmission to the LCD.

themselves.

c6983e3ce0 stmhal: Fix timer capture/compare interrupt handling for TIM1 and TIM8.
It turns out that TIM1 and TIM8 have their own Capture/Compare
interrupt vector. For all of the other timers, the capture/compare
interrupt vector is the same as the update vector.

So we need to add handlers for these vectors and enable them
when using capture/compare callbacks.

During testing of this, I also found that passing a channel callback
into the channel constructor would not enable interrupts properly.

I tested using:
```
>>> pyb.Timer(1, freq=4).channel(1, pyb.Timer.OC_TOGGLE, callback=lambda t: print('.', end=''))
```
I tested the above with channels 1, 4, and 8

af9889f99a stmhal/adc.c: Get ADC working on STM32L4 MCUs.
Fixing Issue #2243. Main problems were:

- HAL_ADC_GetState(adcHandle) may return other bits set (not only
  HAL_ADC_STATE_EOC_REG) when called - so I AND-ed it out as proposed by
  mattbrejza in Issue #2243.
- ADC Pin has to be configured as GPIO_MODE_ANALOG_ADC_CONTROL not only
  GPIO_MODE_ANALOG.
- Resolved ADC resolution L4 specific (Use L4 define ADC_RESOLUTION_12B).
- Changed setting of Init.EOCSelection toADC_EOC_SINGLE_CONV for L4.
- Added call to ADC_MultiModeTypeDef as this is done on a STM32Cube
  generated project too.
- Clean up: Configuration of ADC is done only in ONE function not the same
  is done in two functions.

Test is done on PA5 pin of STM32L4Discovery-Kit which is connected to the
DOWN button.

Thanks to mattbrejza for discovering the bug.
