056e0b6293 stm32/spi: Add implementation of low-level SPI protocol.
Can be used, for example, to configure external SPI flash using a hardware
SPI interface (code to be put in a board's bdev.c file):

    STATIC const spi_proto_cfg_t hard_spi_bus = {
        .spi = &spi_obj[5],
        .baudrate = 10000000,
        .polarity = 0,
        .phase = 0,
        .bits = 8,
        .firstbit = SPI_FIRSTBIT_MSB,
    };

    STATIC mp_spiflash_cache_t spi_bdev_cache;

    const mp_spiflash_config_t spiflash_config = {
        .bus_kind = MP_SPIFLASH_BUS_SPI,
        .bus.u_spi.cs = pin_A0,
        .bus.u_spi.data = (void*)&hard_spi_bus,
        .bus.u_spi.proto = &spi_proto,
        .cache = &spi_bdev_cache,
    };

    spi_bdev_t spi_bdev;

8300be6d0f stm32/spi: Split out pyb.SPI and machine.SPI bindings to their own files
The aim here is to have spi.c contain the low-level SPI driver which is
independent (not fully but close) of MicroPython objects and methods, and
the higher-level bindings are separated out to pyb_spi.c and machine_spi.c.

48d736f491 esp32: Update to latest ESP IDF.
Among other things, this requires putting bootloader object files in to
their relevant .a archive, so that they can be correctly referenced by the
ESP IDF's linker script.

e562f99263 stm32/sdram: Allow additional config by a board, and tune MPU settings.

- Increase MPU region size to 8MiB.
- Make SDRAM region cacheable and executable.

fe1ef507ef unix/Makefile: coverage: Explicitly build "axtls" too.
"coverage" build uses different BUILD directory comparing to the normal
build. Previously, any build picked up libaxtls.a from normal build's
directory, but that was fixed recently. So, for each build, we must
build axtls explicitly.

This fixes Travis build in particular.

3f9d3e120b windows/msvc: Support custom compiler for header generation.
Use overrideable properties instead of hardcoding the use of the
default cl executable used by msvc toolsets. This allows using
arbitrary compiler commands for qstr header generation.
The CLToolExe and CLToolPath properties are used because they are,
even though absent from any official documentation, the de-facto
standard as used by the msvc toolsets themselves.

86e0b25532 stm32/spi: Round up prescaler calc to never exceed requested baudrate.
Requesting a baudrate of X should never configure the peripheral to have a
baudrate greater than X because connected hardware may not be able to
handle higher speeds.  This patch makes sure to round the prescaler up so
that the actual baudrate is rounded down.

c62b23094f stm32/adc: Disable VBAT in read channel helper function.
Prior to this patch, if VBAT was read via ADC.read() or
ADCAll.read_channel(), then it would remain enabled and subsequent reads
of TEMPSENSOR or VREFINT would not work.  This patch makes sure that VBAT
is disabled for all cases that it could be read.

da2d2b6d88 py/mpconfig.h: Introduce MICROPY_DEBUG_PRINTER for debugging output.
This patch in effect renames MICROPY_DEBUG_PRINTER_DEST to
MICROPY_DEBUG_PRINTER, moving its default definition from
lib/utils/printf.c to py/mpconfig.h to make it official and documented, and
makes this macro a pointer rather than the actual mp_print_t struct.  This
is done to get consistency with MICROPY_ERROR_PRINTER, and provide this
macro for use outside just lib/utils/printf.c.

Ports are updated to use the new macro name.

7f0c5f2ef9 nrf: Enable all PWM, RTC and Timer instances for nrf52840.
The NRF52 define only covers nrf52832, so update the define checks
to use NRF52_SERIES to cover both nrf52832 and nrf52840.

Fixed machine_hard_pwm_instances table in modules/machine/pwm.c

This enables PWM(0) to PWM(3), RTCounter(2), Timer(3) and Timer(4),
in addition to NFC reset cause, on nrf52840.

Provides new mp_hal_pin_config_alt_static(pin_obj, mode, pull, fn_type)
function declared in pin_static_af.h to allow configuring pin alternate
functions by name at compile time.

ef554ef9a2 unix: Use MP_STREAM_GET_FILENO to allow uselect to poll general objects.
This mechanism will scale to to an arbitrary number of pollable objects, so
long as they implement the MP_STREAM_GET_FILENO ioctl.  Since ussl objects
pass through ioctl requests transparently to the underlying socket object,
it will allow ussl sockets to be polled.  And a user object with uio.IOBase
as a base could support polling.

cf58ef27af nrf: Quick-fix on const objects with open array dimension in objtuples.
Temporarly solving the issue of
"differ from the size of original declaration [-Werror=lto-type-mismatch]
until linker is fixed in upcomming release of gcc.

Bug is reported by others, and will be fixed in next version of arm-gcc.
However, this patch makes it possible to use modmusic and modimage
with current compilers.

Alternativly, the code can be compiled with LTO=0, but uses valuable 9K
more on this already squeezed target (microbit).

report reported to the module to keep old behaviour of the
Scanner class.

db67a5000f nrf: Generalize feather52 target
This patch generalize the feather52 target to be a board without
an in-built Bluetooth stack or bootloader giving all flash memory to
micropython code.

This way the feather52 target can run any supported Bluetooth LE
stack the port supports for other nrf52832 targets. Hence, this
make Makefiles/linker scripts and BLE driver support easier
to maintain in the future.

b7ce2f1460 nrf: Add support for reading output pin state
Current adoption on top of nrfx only reads the GPIO->IN register.
In order to read back an output state, nrf_gpio_pin_out_read has
to be called.

This patch concatinate the two read functions such that, if
either IN or OUT register has a value 1 it will return this,
else 0.

Updating lib/nrfx submodule to latest version of master to get
the new GPIO API to read pin direction.
