27c149efe0 stmhal: Add pyb.fault_debug() function, to control hard-fault behaviour.
This new function controls what happens on a hard-fault:
- debugging disabled: board will do a reset
- debugging enabled: board will print registers and stack and flash LEDs

The default is disabled, ie to do a reset.  This is different to previous
behaviour which flashed the LEDs and waited indefinitely.

882ec01e42 stmhal: Initial implementation of multithreading, currently disabled.
This patch brings the _thread module to stmhal/pyboard.  There is a very
simple round-robin thread scheduler, which is disabled if there is only
one thread (for efficiency when threading is not used).

The scheduler currently switches threads at a rate of 250Hz using the
systick timer and the pend-SV interrupt.

The GIL is disabled so one must be careful to use lock objects to prevent
concurrent access of objects.

The threading is disabled by default, one can enabled it with the config
option MICROPY_PY_THREAD to test it out.

3667ee1b88 stmhal: On boot, mount all available partitions of the SD card.
The first partition is mounted as "/sd" and subsequent partitions are
mounted as "/sd<part_num>".  This is backwards compatible with the previous
behaviour, which just mounted the first partition on "/sd".

At this point, only FatFs filesystems are mounted.

84c614e729 stmhal: Convert to use VFS sub-system and new ooFatFs component.
This patch makes the following configuration changes:
- MICROPY_FSUSERMOUNT is disabled, removing old mounting infrastructure
- MICROPY_VFS is enabled, giving new VFS sub-system
- MICROPY_VFS_FAT is enabled, giving uos.VfsFat type
- MICROPY_FATFS_OO is enabled, to use new ooFatFs lib, R0.12b

User facing API should be almost unchanged.  Most notable changes are
removal of os.mkfs (use os.VfsFat.mkfs instead) and pyb.mount doesn't
allow unmounting by passing None as the device.

Damien George
d6a2d00167 stmhal: Add ability to have filesystem stored on external SPI flash.
To use this feature a port should define MICROPY_HW_SPIFLASH_SIZE_BITS
along with x_CS, x_SCK, x_MOSI, x_MISO (x=MICROPY_HW_SPIFLASH).  This will
then use external SPI flash on those pins instead of the internal flash.

The SPI is done using the software implementation.  There is currently only
support for standard SPI (ie not dual or quad mode).

e81116d07d stmhal/uart: Increase inter-character timeout by 1ms.
Sys-tick resolution is 1ms and a value of 2 will give a delay between 1ms
and 2ms (whereas a value of 1 gives a delay between 0ms and 1ms, which is
too short).

16a584d7cf stmhal/uart: Provide a custom function to transmit over UART.
The HAL_UART_Transmit function has changed in the latest HAL version such
that the Timeout is a timeout for the entire function, rather than a
timeout between characters as it was before.  The HAL function also does
not allow one to reliably tell how many characters were sent before the
timeout (if a timeout occurred).

This patch provides a custom function to do UART transmission, completely
replacing the HAL version, to fix the above-mentioned issues.

e202b6f586 stmhal/sdcard: Use mp_hal_pin_config function instead of HAL_GPIO_Init.
There is a minor functional change with this patch, that the GPIO are now
configured in fast mode, whereas they were in high speed mode before.  But
the SDIO should still work because SD CK frequency is at most 25MHz.

425150040c stmhal/mphalport.h: Explicitly use HAL's GPIO constants for pull modes.
They are the same as the existing raw constants (namely 0, 1, 2) but we
want to explicitly show that one can use the HAL's constants if necessary
(eg the mpconfigboard.h files do use the HAL's constants to define the
pull state of certain configurable pins).

b14abab9cd stmhal/led: Properly initialise timer handle to zero before using it.
Without this the timer will have random values for its State and Lock
entries.  The object can then be in a locked state leading to some HAL
functions returning immediately with an error code (which is unchecked).

This patch fixes such a bug which did manifest itself as PWM not working
correctly for LEDs.

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

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.

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.

3053748987 stmhal: Add beginnings of port-specific machine.I2C implementation.
This allows one to construct an I2C object using ids that are specific

protocol functions to hardware implementations later on.

13400e1375 stmhal/hal: do not include <stdio.h> in HAL headers
stdio.h was included in all HAL files only to provide
definition of NULL symbol

"stdio.h" includes "types.h" which contains some conflicting definitions
with "drivers/cc3000/inc/socket.h"
