e3b877826c nrf/modules/machine/soft_pwm: Add PWM for nrf51x boards using soft PWM.
Using extmod/machine_pwm.c for the Python bindings and the existing
softpwm.c driver, by just adding the interface.

Properties:
- Frequency range 1-3906 Hz.
- All PWM outputs run at the same frequency but can have different duty
  cycles.
- Limited to the P0.x pins.

Since it uses the existing softpwm.c mechanism, it will be affected by
playing music with the music class.

a1f838cdf1 nrf/modules/machine/pwm: Use extmod/machine_pwm.c for PWM module.
This is a breaking change, making the hardware PWM on the nrf port
compatible with the other ports providing machine.PWM.

Frequency range 4Hz - ~5.4 MHz.  The base clock range is 125kHz to 16 MHz,
and the divider range is 3 - 32767.

The hardware supports up to four outputs per PWM device with different duty
cycles, but only one output is (and was) supported.

cc645b65a9 nrf/boards/arduino_nano_33_ble_sense: Add support for REV-2 chipset.
These changes allow the firmware to support both the REV-1 and REV-2
versions of the board:
- Freeze the new device drivers used in REV-2.
- Add a board-level module that abstracts the IMU chipset.

564945a2a0 nrf/boards/seeed_xiao_nrf52: Add defn for Seeed XIAO NRF52840 Sense.
It keeps compatibility with the XIAO bootloader by:
- using Soft Device 7.3.0
- reserving 48k memory for the bootloader.

So on double reset a drive pops for uploading an uf2 image or a nrfutil zip
pkg file.  Instructions to create it from a hex file are included.  The
bootloader can as well be activated with the touch 1200 option of nrfutil.

The script download_ble_stack.sh has been adapted to get the version 7.3.0
soft device files.  It may have to be executed once before building.

The file system is set to 256k and the pin definitions are adapted.
Besides that, it has the common functionality and omissions.  The on-board
sensors and additional flash can be supported by Python scripts.

e8f5cfe0e1 nrf: Rename MICROPY_PY_MACHINE_TIMER to MICROPY_PY_MACHINE_TIMER_NRF.
So that it doesn't clash with the extmod version.

Also make the default for this enabled, so that most boards do not need to

94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
Instead of being an explicit field, it's now a slot like all the other
methods.

This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.

6da41b5900 py/obj: Merge getiter and iternext mp_obj_type_t slots.
The goal here is to remove a slot (making way to turn make_new into a slot)
as well as reduce code size by the ~40 references to mp_identity_getiter
and mp_stream_unbuffered_iter.

This introduces two new type flags:
- MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the
  type is "iternext", and should use the identity getiter.
- MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer
  to a mp_getiter_iternext_custom_t instance, which then defines both
  getiter and iternext.

And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This
means that the type should use the identity getiter, and
mp_stream_unbuffered_iter as iternext.

Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give
the default case where "iter" is "getiter".

fb2a57800a all: Simplify buffer protocol to just a "get buffer" callback.
The buffer protocol type only has a single member, and this existing layout
creates problems for the upcoming split/slot-index mp_obj_type_t layout
optimisations.

If we need to make the buffer protocol more sophisticated in the future
either we can rely on the mp_obj_type_t optimisations to just add
additional slots to mp_obj_type_t or re-visit the buffer protocol then.

This change is a no-op in terms of generated code.

Jim Mussared
203dae41fb all: Update all manifest.py files to use new features.
Changes in this commit:
- Manifest include's now use the directory path where possible (no longer
  necessary to include the manifest.py file explicitly).
- Add manifest.py for all drivers and components that are referenced by
  port/board manifests.
- Replace all uses of freeze() with package()/module(), except for port and
  board modules.
- Use opt=3 everywhere, for consistency and to reduce code size.
- Use require() instead of include() for all micropython-lib references.
- Remove support for optional board-level manifest.py in mimxrt port, to
  make it behave the same as other ports (the board must set
  FROZEN_MANIFEST to a custom manifest.py, which can optionally include the
  default, port-level manifest).
- Also reinstates modules that were accidentally removed from the esp8266
  512k build in fbe9417b90.

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".

82fe6b0526 nrf: Add nrf9160 base support.
This patch add basic building blocks for nrf9P60.

It also includes a secure bootloader which forwards all
possible peripherals that are user selectable to become
non-secure. After configuring Flash, RAM and peripherals
the secure bootloader will jump to the non-secure domain
where MicroPython is placed.

The minimum size of a secure boot has to be a flash
block of 32Kb, hence why the linker scripts are
offsetting the main application this much.

The RAM offset is set to 128K, to allow for later
integration of Nordic Semiconductor's BSD socket
library which reserves the range 0x20010000 - 0x2001FFFF.
