990341d18e nrf: Facilitate use of freeze manifest.
Update the Makefile to handle FROZEN_MANIFEST, and the README with some
small samples on how to use freeze manifests.  And add BOARD_DIR to the
Makefile which can be referenced in boards/<board>/mpconfigboard.mk to
include a board specific manifest.

0bde907a8b nrf/Makefile: Add _fs_size linker script override from make.
Add posibility to override linker script "_fs_size" from make by adding the
FS_SIZE parameter.  The syntax of value is linker script syntax.  For
example, the value of 131072 bytes can be written as 128K like this:
FS_SIZE=128K.

If not set, default value for "_fs_size" from linker script will be used.

ad4656b861 all: Rename BYTES_PER_WORD to MP_BYTES_PER_OBJ_WORD.
The "word" referred to by BYTES_PER_WORD is actually the size of mp_obj_t
which is not always the same as the size of a pointer on the target
architecture.  So rename this config value to better reflect what it
measures, and also prefix it with MP_.

For uses of BYTES_PER_WORD in setting the stack limit this has been
changed to sizeof(void *), because the stack usually grows with
machine-word sized values (eg an nlr_buf_t has many machine words in it).

d0b8554df4 nrf: Change selected boards to utilize pre-flashed bootloader.
The nrf52840-mdk-usb-dongle and pca10050 comes with a pre-flashed
bootloader (OpenBootloader).

This commit updates the boards "mpconfigboard.mk" to use DFU as
default flashing method and set the corresponding BOOTLOADER
settings such that nrf52840_open_bootloader_1.2.x.ld linker
script is used.

The default DFU flashing method can be disabled by issuing "DFU=0"
when invoking make. This will lead to "segger" being used as default
flashing tool. When using "DFU=0", the linker scripts will not
compensate for any MBR and Bootloader region being present, and might
overwrite them if they were present.

The commit also removes the custom linker script specific to
nrf52840-mdk-usb-dongle as it now points to a generic.

Updated nrf52840-mdk-usb-dongle's README.md to be more clear on
how to deploy the built firmware.

The port README.md has also been updated. In the list of target
boards a new column has been added to indicate which bootloader
is present on the target board. And for consistency, changed all
examples in the README.md to use "deploy" instead of "flash".

634f6df324 nrf/Makefile: Add support for flashing with nrfutil.
An additional Makefile parameter NRFUTIL_PORT can be set in order
to define the serial port to used for the DFU (Default: /dev/ttyACM0).

The "nrfutil" that is used as flasher towards OpenBootloader is
available for installation through Python "pip".

In case of SD=s140, SoftDevice ID 0xB6 is passed to nrfutil's package
generation which corresponds to SoftDevice s140 v6.1.1.

718397a37d nrf/Makefile: Add bootloader specific section.
Add the option for "mpconfigboard.mk" to define whether the
board hosts a bootloader or not. The BOOTLOADER make variable
must be set to the name of the bootloader.

When the BOOTLOADER name is set it is also required to supply
the BOOTLOADER_VERSION_MAJOR and the BOOTLOADER_VERSION_MINOR
from the "mpconfigboards.mk". These will be used to resolve which
bootloader linker script that should be passed to the linker.

The BOOTLOADER section also supplies the C-compiler with
BOOTLOADER_<bootloader name>=<version major><version minor>
as a compiler define. This is for future use in case a bootloader
needs to do modification to the startup files or similar (like
setting the VTOR specific to a version of a bootloader).

- _bootloader_tail_size:

- _bootloader_head_ram_size:
    Bootloader RAM usage in front of the application.

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.

Fixes issue #6623 (where calling .init() on a HW I2C would crash).

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.
