Damien George 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;

Damien George 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.

Damien George d966a33486 stm32: Change header include guards from STMHAL to STM32 to match dir. 2018-02-15 15:47:04 +11:00
Damien George 4ad3ede21a stm32/spi: Provide better separation between SPI driver and uPy objs. 
There is an underlying hardware SPI driver (built on top of the STM HAL)
and then on top of this sits the legacy pyb.SPI class as well as the
machine.SPI class.  This patch improves the separation between these
layers, in particular decoupling machine.SPI from pyb.SPI.

Damien George 01dd7804b8 ports: Make new ports/ sub-directory and move all ports there. 
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
