Damien George efe23aca71 all: Remove third argument to MP_REGISTER_MODULE.
It's no longer needed because this macro is now processed after
preprocessing the source code via cpp (in the qstr extraction stage), which
means unused MP_REGISTER_MODULE's are filtered out by the preprocessor.

Damien George fbd47fc46c ports: Consolidate inclusion of umachine module in built-ins.
The inclusion of `umachine` in the list of built-in modules is now done
centrally in py/objmodule.c.  Enabling MICROPY_PY_MACHINE will include this
module.

As part of this, all ports now have `umachine` as the core module name
(previously some had only `machine` as the name).

Mike Teachman 8a5bfe44a5 esp32,stm32: Add new machine.I2S class for I2S protocol support.
This commit adds I2S protocol support for the esp32 and stm32 ports, via
a new machine.I2S class.  It builds on the stm32 work of blmorris, #1361.

Features include:
- a consistent I2S API across the esp32 and stm32 ports
- I2S configurations supported:
  - master transmit and master receive
  - 16-bit and 32-bit sample sizes
  - mono and stereo formats
  - sampling frequency
  - 3 modes of operation:
    - blocking
    - non-blocking with callback
    - uasyncio
  - internal ring buffer size can be tuned
- documentation for Pyboards and esp32-based boards
- tested on the following development boards:
  - Pyboard D SF2W
  - Pyboard V1.1
  - ESP32 with SPIRAM
  - ESP32

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.

renaming of pyb -> machine, and also the machine_idle definition (was
pyb_wfi) is moved to modmachine.c.

Damien George 48b25a841b stm32: Add machine.Timer with soft timer implementation.
This commit adds an implementation of machine.Timer backed by the soft
timer mechanism.  It allows an arbitrary number of timers with 1ms
resolution, with an associated Python callback.  The Python-level API
matches existing ports that have a soft timer, and is used as:

    from machine import Timer
    t = Timer(freq=10, callback=lambda t:print(t))
    ...
    t = Timer(mode=Timer.ONE_SHOT, period=2000, callback=lambda t:print(t))
    ...
    t.deinit()

now works with stm32.

Damien George 04c7cdb668 stm32: Enter bootloader via a system reset.
Entering a bootloader (ST system bootloader, or custom mboot) from software
by directly branching to it is not reliable, and the reliability of it
working can depend on the peripherals that were enabled by the application
code.  It's also not possible to branch to a bootloader if the WDT is
enabled (unless the bootloader has specific provisions to feed the WDT).

This patch changes the way a bootloader is entered from software by first
doing a complete system reset, then branching to the desired bootloader
early on in the start-up process.  The top two words of RAM (of the stack)
are reserved to store flags indicating that the bootloader should be
entered after a reset.

Damien George e1e3704aa1 stm32/modmachine: Create dedicated asm function to branch to bootloader.
Recent gcc versions (at least 9.1) give a warning about using "sp" in the

instead used to set SP and branch to the bootloader so the code has full
control over what happens.

Damien George 1acf58c08f stm32/modmachine: Re-enable PLLSAI[1] after waking from stop mode.
On F7s PLLSAI is used as a 48MHz clock source if the main PLL cannot
provide such a frequency, and on L4s PLLSAI1 is always used as a clock
source for the peripherals.  This commit makes sure these PLLs are
re-enabled upon waking from stop mode so the peripherals work.

See issues #4022 and #4178 (L4 specific).

Damien George 47550ef2cd stm32: For MCUs that have PLLSAI allow to set SYSCLK at 2MHz increments.
MCUs that have a PLLSAI can use it to generate a 48MHz clock for USB, SDIO
and RNG peripherals.  In such cases the SYSCLK is not restricted to values
that allow the system PLL to generate 48MHz, but can be any frequency.
This patch allows such configurability for F7 MCUs, allowing the SYSCLK to
be set in 2MHz increments via machine.freq().  PLLSAI will only be enabled
if needed, and consumes about 1mA extra.  This fine grained control of
frequency is useful to get accurate SPI baudrates, for example.
