Damien George 80e79a777d zephyr: Add initial ubluetooth module integration.
Currently only advertising and scanning are supported, using the ring
buffer for events (ie not synchronous events at this stage).

The ble_gap_advertise.py multi-test passes (tested on a nucleo_wb55rg
board).

Maureen Helm 3331b1811d zephyr: Disable CONFIG_NET_SOCKETS_POSIX_NAMES.
Zephyr's default value for CONFIG_NET_SOCKETS_POSIX_NAMES was changed
from false to true between Zephyr v2.5.0 and v2.6.0. This caused
conflicts in MicroPython, which uses the zsock_ prefixed functions, so
disable it.

Maureen Helm f573e73bae zephyr: Build MicroPython as a cmake target.
Refactors the zephyr build infrastructure to build MicroPython as a
cmake target, using the recently introduced core cmake rules.

This change makes it possible to build the zephyr port like most other
zephyr applications using west or cmake directly. It simplifies building
with extra cmake arguments, such as specifying an alternate conf file or
adding an Arduino shield. It also enables building the zephyr port
anywhere in the host file system, which will allow regressing across
multiple boards with the zephyr twister script.

Maureen Helm 92a5ee6ac1 zephyr: Replace broken shell_net_iface() with more general shell_exec().
The zephyr function net_shell_cmd_iface() was removed in zephyr v1.14.0,
therefore the MicroPython zephyr port did not build with newer zephyr
versions when CONFIG_NET_SHELL=y. Replace with a more general
shell_exec() function that can execute any zephyr shell command. For
example:

Damien George 64180f0742 extmod/machine_i2c: Add init protocol method for generic I2C bindings.
Hardware I2C implementations must provide a .init() protocol method if they
want to support reconfiguration.  Otherwise the default is that i2c.init()
raises an OSError (currently the case for all ports).

mp_machine_soft_i2c_locals_dict is renamed to mp_machine_i2c_locals_dict to
match the generic SPI bindings.

Damien George 39d50d129c ports: Add SoftI2C and SoftSPI to machine module where appropriate.
Previous commits removed the ability for one I2C/SPI constructor to
construct both software- or hardware-based peripheral instances.  Such
construction is now split to explicit soft and non-soft types.

This commit makes both types available in all ports that previously could
create both software and hardware peripherals: machine.I2C and machine.SPI
construct hardware instances, while machine.SoftI2C and machine.SoftSPI
create software instances.

This is a breaking change for use of software-based I2C and SPI.  Code that
constructed I2C/SPI peripherals in the following way will need to be
changed:

    machine.I2C(-1, ...)            ->  machine.SoftI2C(...)
    machine.I2C(scl=scl, sda=sda)   ->  machine.SoftI2C(scl=scl, sda=sda)

    machine.SPI(-1, ...)            ->  machine.SoftSPI(...)
    machine.SPI(sck=sck, mosi=mosi, miso=miso)
                        ->  machine.SoftSPI(sck=sck, mosi=mosi, miso=miso)

Code which uses machine.I2C and machine.SPI classes to access hardware
peripherals does not need to change.

Maureen Helm 25434e976b zephyr: Use zephyr build system to merge configurations.
The zephyr build system supports merging application-level board
configurations, so there is no need to reproduce this functionality in
MicroPython.

If CONF_FILE is not explicitly set, then the zephyr build system looks for
prj.conf in the application directory.  Therefore we rename the MicroPython
prj_base.conf to prj.conf.

Furthermore, if the zephyr build system finds boards/$(BOARD).conf in the
application directory, it merges that configuration with prj.conf.
Therefore we rename all the MicroPython board .conf files and move them
into a boards/ directory.

The minimal configuration, prj_minimal.conf, is left in the application
directory because it is used as an explicitly set CONF_FILE in
make-minimal.

Maureen Helm 7a5752a748 zephyr: Enable littlefs.
Enables the littlefs (v1 and v2) filesystems in the zephyr port.

Example usage with the internal flash on the reel_board or the
rv32m1_vega_ri5cy board:

import os
from zephyr import FlashArea
bdev = FlashArea(FlashArea.STORAGE, 4096)
os.VfsLfs2.mkfs(bdev)
os.mount(bdev, '/flash')
with open('/flash/hello.txt','w') as f:
    f.write('Hello world')
print(open('/flash/hello.txt').read())

Things get a little trickier with the frdm_k64f due to the micropython
application spilling into the default flash storage partition defined
for this board. The zephyr build system doesn't enforce the flash
partitioning when mcuboot is not enabled (which it is not for
micropython). For now we can demonstrate that the littlefs filesystem
works on frdm_k64f by constructing the FlashArea block device on the
mcuboot scratch partition instead of the storage partition. Do this by
replacing the FlashArea.STORAGE constant above with the value 4.
