7ea192af05 nrf/modules/machine/uart: Add timeout keyword options and "any" method.
Changes in this commit:
- Add the timeout and timeout_char keyword options.
- Make uart.read() non-blocking.
- Add uart.any().
- Add ioctl MP_STREAM_POLL handling.
- Change uart.write() into non-busy waiting. uart.write() still waits until
  all data has been sent, but calls MICROPY_EVENT_POLL_HOOK while waiting.
  uart.write() uses DMA for transfer.  One option would be to add a small
  local buffer, such that transfers up to the size of the buffer could be
  done without waiting.
- As a side effect to the change of uart.write(), uart.txdone() and ioctl
  flush now report/wait correctly for the end of transmission.
- Change machine_hard_uart_buf_t in machine_hard_uart_obj_t to an instance
  of that struct, rather than a pointer to one.

ed1f42cb49 nrf/modules/machine/pwm: Support using all 4 channels of a PWM module.
These have the same frequency, but can have different duty cycle and
polarity.

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.

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.

d6d8722558 extmod: Make extmod.mk self-contained.
This makes it so that all a port needs to do is set the relevant variables
and "include extmod.mk" and doesn't need to worry about adding anything to
OBJ, CFLAGS, SRC_QSTR, etc.

Make all extmod variables (src, flags, etc) private to extmod.mk.

Also move common/shared, extmod-related fragments (e.g. wiznet, cyw43,
bluetooth) into extmod.mk.

Now that SRC_MOD, CFLAGS_MOD, CXXFLAGS_MOD are unused by both extmod.mk
(and user-C-modules in a previous commit), remove all uses of them from
port makefiles.

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.

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

- 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.

8a0ee5a5c0 py/objstr: Split mp_obj_str_from_vstr into bytes/str versions.
Previously the desired output type was specified.  Now make the type part
of the function name.  Because this function is used in a few places this
saves code size due to smaller call-site.

This makes `mp_obj_new_str_type_from_vstr` a private function of objstr.c
(which is almost the only place where the output type isn't a compile-time
constant).

This saves ~140 bytes on PYBV11.

8f4c108025 all: Remove MICROPY_PY_IO_FILEIO config option.
Since commit e65d1e69e8 there is no longer an
io.FileIO class, so this option is no longer needed.

This option also controlled whether or not files supported being opened in
binary mode (eg 'rb'), and could, if disabled, lead to confusion as to why
opening a file in binary mode silently did the wrong thing (it would just
open in text mode if MICROPY_PY_IO_FILEIO was disabled).

The various VFS implementations (POSIX, FAT, LFS) were the only places
where enabling this option made a difference, and in almost all cases where
one of these filesystems were enabled, MICROPY_PY_IO_FILEIO was also
enabled.  So it makes sense to just unconditionally enable this feature
(ability to open a file in binary mode) in all cases, and so just remove
this config option altogether.  That makes configuration simpler and means
binary file support always exists (and opening a file in binary mode is
arguably more fundamental than opening in text mode, so if anything should
be configurable then it should be the ability to open in text mode).

a16a330da5 nrf,stm32: Don't enable debug info by default if LTO is on.
It seems sometimes gcc with LTO will generate otherwise valid assembly
listings that cause 'as' to error out when generating DWARF debug info; see
https://sourceware.org/bugzilla/show_bug.cgi?id=29494

Therefore, don't enable -g by default if LTO is on.

Enabling LTO=1 DEBUG=1 is still possible but may result in random errors
at link time due to 'as' (the error in this case is "Error: unaligned
opcodes detected in executable segment", and the only other easy workaround
is CFLAGS+=-fno-jump-tables which may increase code size significantly).

Some devices, such as the LightBlue BTLE app on iOS, try to use Bluetooth 5

If this event isn't handled, LightBlue (and likely other Bluetooth 5.0

"Connecting..." state forever.  This message should be replied to with
sd_ble_gap_phy_update, as documented in
