38ac23c942 stmhal: NUCLEO 401 - Add a bunch of missing pins and reorder the pins
This groups the pins for a port together and puts them in numerical
order. It also adds ARDUINO pin names.

7bb501ef9f stmhal: Add a function for setting the pin alternate function
mp_hal_gpio_set_af will search for a given function and unit
and set the alternate function to the alternate function index
found.

b33a770596 extmod/fsusermount: Support mounting of multiple block devices.
This patch adds support to fsusermount for multiple block devices
(instead of just one).  The maximum allowed is fixed at compile time by
the size of the fs_user_mount array accessed via MP_STATE_PORT, which
in turn is set by MICROPY_FATFS_VOLUMES.

With this patch, stmhal (which is still tightly coupled to fsusermount)
is also modified to support mounting multiple devices   And the flash and
SD card are now just two block devices that are mounted at start up if
they exist (and they have special native code to make them more
efficient).

3770cd2e70 stmhal: Expose flash and SD card as proper objects with block protocol.
You can now create (singleton) objects representing the flash and SD
card, using:

    flash = pyb.Flash()
    sdcard = pyb.SDCard()

These objects provide the block protocol.

a888d5ab91 stmhal: Improve NUCLEO-F401RE build, with UART2 as REPL.
This enables MICROPY_HW_HAS_FLASH which got missed.

The HW has UART2 on the 401 connected to the STLINK procesor
which exposes it as USB serial. This connects that up so that
you can get a REPL using the USB serial.

13a4c120ce lib/fatfs: Add support for sector sizes larger than 512 bytes.
If MICROPY_FATFS_MAX_SS is defined to power of 2 value between 1024 and
4096, support for dynamic sector size in FatFs will be enabled.  Note
that FatFs reserves static buffer of MICROPY_FATFS_MAX_SS size for each
filesystem in use, so that value should be set sparingly.

Initial patch provided by @pfalcon.

c33ad60a67 extmod/fsusermount: Change block protocol to support ioctl method.
The new block protocol is:
- readblocks(self, n, buf)
- writeblocks(self, n, buf)
- ioctl(self, cmd, arg)

The new ioctl method handles the old sync and count methods, as well as
a new "get sector size" method.

The old protocol is still supported, and used if the device doesn't have
the ioctl method.

5b85a86ce3 extmod/fsusermount: Introduce separate mkfs() function.

and new mkfs() is rought and takes more args than needed. But is a step
in a forward direction.

3e02b1d19a py/viper: Allow casting of Python integers to viper pointers.
This allows you to pass a number (being an address) to a viper function
that expects a pointer, and also allows casting of integers to pointers
within viper functions.

This was actually the original behaviour, but it regressed due to native
type identifiers being promoted to 4 bits in width.

ab0e36b3da stmhal/file: For self-contained usecase, don't define global types.
If MICROPY_VFS_FAT is defined, mp_type_fileio & mp_type_textio won't be
defined, as these may be alredy defined elsewhere. The idea is to have
compartmentalized VFS FatFs class, which can work in parallel with some
other "main" filesystem. E.g., for unix port, mp_type_fileio, etc. will
be defined for the main POSIX filesystem, while stmhal/file.c will be
a self-contained VFS file class.

350ab0f570 stmhal/file: Recast as "FatFs file" class, to support other VFS types.
Move definition of mp_builtin_open_obj to a separate module, then file.c
becomes more or less compartmentalized FatFs file class, which can be used
together with file class implementations for other (V)FSes.

ff1a96ce2c py/mpz: Add commented-out mpz_pow3_inpl function, to compute (x**y)%z.
This function computes (x**y)%z in an efficient way.  For large arguments
this operation is otherwise not computable by doing x**y and then %z.

It's currently not used, but is added in case it's useful one day.

2e2e15cec2 py/mpz: Complete implementation of mpz_{and,or,xor} for negative args.
For these 3 bitwise operations there are now fast functions for
positive-only arguments, and general functions for arbitrary sign
arguments (the fast functions are the existing implementation).

By default the fast functions are not used (to save space) and instead
the general functions are used for all operations.

Enable MICROPY_OPT_MPZ_BITWISE to use the fast functions for positive
arguments.

5f3e005b67 py: Extend native type-sig to use 4 bits, so uint is separate to ptr.
Before this patch, the native types for uint and ptr/ptr8/ptr16/ptr32
all overlapped and it was possible to make a mistake in casting.  Now,
these types are all separate and any coding mistakes will be raised
as runtime errors.

ea040a4f9a stmhal: In HAL I2C driver, move DMA setup to after sending I2C address.
Previous to this patch the DMA was setup and then the I2C address sent.
If the I2C address sending failed (eg no I2C device on the bus) then the
DMA was left in an inconsistent state.

This patch moves the DMA setup to after a successful sending of the I2C
address(es).

See issue #1765.

a8a4b01af6 stmhal: Add PWM capability for LED(3) and LED(4) on pyboards.
USB CDC no longer needs TIM3 (which was originally used for LED(4) PWM)
and so TIM3 has been freed for general purpose use by the user.  Hence
LED(4) lost its PWM capabilities.

This patch reinstates the PWM capabilities using a semi-generic piece
of code which allows to configure a timer and PWM channel to use for any
LED.  But the PWM capability is only configured if the LED is set to an
intensity between 1 and 254 (ie only when needed).  In that case the
relevant timer is configured for PWM.  It's up to the user to make sure
the timers are not used if PWM is active.

This patch also makes sure that PWM LEDs are turned off using standard
GPIO when calling led.off() or led.intensity(0), instead of just setting
the PWM counter to zero.

ea89b80ff4 stmhal: Make TIM3 available for use by the user.

d363133917 stmhal: Make USB CDC driver use SOF instead of TIM3 for outgoing data.
Previous to this patch the USB CDC driver used TIM3 to trigger the
sending of outgoing data over USB serial.  This patch changes the
behaviour so that the USB SOF interrupt is used to trigger the processing
of the sending.  This reduces latency and increases bandwidth of outgoing
data.

Thanks to Martin Fischer, aka @hoihu, for the idea and initial prototype.

See PR #1713.

d3b1f0b627 py/runtime: mp_stack_ctrl_init() should be called immediately on startup.
Calling it from mp_init() is too late for some ports (like Unix), and leads
to incomplete stack frame being captured, with following GC issues. So, now
each port should call mp_stack_ctrl_init() on its own, ASAP after startup,
and taking special precautions so it really was called before stack variables
get allocated (because if such variable with a pointer is missed, it may lead
to over-collecting (typical symptom is segfaulting)).
