f0399d35e4 samd/modmachine: Get the bootloader magic address from the lib.
Instead of being hard-coded, and then it works for all MCUs.

That fits except for a Sparkfun SAMD51 Thing Plus (known) bug, which uses
192k - 4 as magic address.  Therefore, that address is set as well to avoid
a problem when this bug is fixed by Sparkfun.

03075a6839 samd/modmachine: Implement machine.lightsleep().
Which just sets the CPU clock to 200kHz and switches the peripheral clock
off.  There are two modes:

    machine.lightsleep(duration_ms)

and

    machine.lightsleep()

In any mode any configured pin.irq() event will terminate the sleep.

Current consumption in lightsleep for some boards:
- 1.5 - 2.5 mA when supplied trough an active USB
  (Seeed XIAO w/o power LED, Adafruit ItsyBitsy)
- 0.8 - 2 mA when supplied through Gnd/+5V (Vusb)
  (Seeed XIAO w/o power LED, Adafruit ItsyBitsy)
- < 1 mA for SAMD51 when supplied trough a battery connector
  (Sparkfun Thing SAMD51 plus)

Related change: move the calls to SysTick_Config() into set_cpu_freq().  It
is required after each CPU freq change to have ticks_ms run at the proper
rate.

4c9e4c3310 samd/mcu/samd51: Enable FAT support for SAMD51.
Tested with a SD card connected to a SAMD51 board.  The SEEED WIO terminal
has a SD-Card reader built-in.

Also a side change to remove a few obsolete lines from Makefile.

1c32cec7f1 samd/clock_config: Support changing machine.freq() for SAMD21.
The range is 1MHz - 48 MHz.  Note that below 8 MHz there is no USB support.
The frequency will be set to an integer fraction of 48 MHz.  And after
changing the frequency, the peripherals like PWM, UART, I2C, SPI have to be
reconfigured.

Current consumption e.g. of the Seeed Xiao board at 1 MHz is about 1.5 mA,
mostly caused by the on-board LED (green LED with 1k resistor at 3.3V).

edc3f3d0d3 samd/clock_config: Extend the range of machine.freq().
The value given for machine.freq(f) is extend to the range of 1_000_000 to
200_000_000.  Frequencies below 48 MHz will be forced to an integer
fraction of 48 MHz.  At frequencies below 8 MHz USB is switched off.  The
power consumption e.g. of ADAFRUIT_ITSYBITSY_M4_EXPRESS drops to about
1.5 mA at 1 MHz.

Since the peripheral frequency is dropped as well, timing e.g. of PWM,
UART, I2C and SPI is affected and frequency/baud rate has to set again
after a frequency change below 48 MHz.

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.

3cc6decfc4 py/py.mk: Make user-C-module handling self-contained in py.mk.
Removes the need for the port to add anything to OBJS or SRC_QSTR.

Also makes it possible for user-C-modules to differentiate between code
that should be processed for QSTR vs other files (e.g. helpers and
libraries).

20e7313453 samd/clock_config: Add HW_DFLL_USB_SYNC and HW_MCU_OSC32KULP extensions.
Two new compile flags are:

MICROPY_HW_DFLL_USB_SYNC: Effective only if DFLL48 does not run from the
crystal.  It will synchronize the DFLL48M clock with the USB's SOF pulse.
If no USB is connected, it will fall back to open loop mode.  The DFLL48M
clock is then pretty precise, but with a higher clock jitter at SAMD51
devices.

MICROPY_HW_MCU_OSC32KULP: Effective only if the devics uses a crystal as
clock source.  Run the MCU clock from the ULP 32kHz oszillator instead of
the crystal.  This flag was added to cater for a interference problem of
the crystal and Neopixel/Debug pins at Adafruit FEATHER Mx boards, which
causes the board to crash.  Drawback: ticks_ms() and time.time() vs. than
ticks_us() and the peripherals like PWM run at not synchronous clocks.

The SAMD21 implementation is an adaption of @jimmo's code for STM32Lxx.
The only changes are the addresses and names of the port registers and the
timing parameters.

SAMD21: The precision is about +/-25ns at 48MHz clock frequency.  The first
two cycles are about 40-60 ns longer than set.  But still good enough to
drive a neopixel device.

SAMD51: The precision is about +/-30ns at 120MHz clock frequency.  Good
enough to drive a neopixel device.

d693758ab2 samd/machine_pwm: Add the machine.PWM class.
Features are:
- 3 to 5 different frequency groups.
- Freq range of 1Hz - 24 MHz.
- Duty rate stays stable on freq change.

Keyword options to the PWM constructor:
- device=n Select a specific PWM device.  If no device is specified, a free
           device is chosen, if available at that pin.
- freq=nnnn
- duty_u16=nnnn
- duty_ns=nnnn
- invert=True/False Allowing two outputs on the same device/channel to have
                    complementary signals.

If both freq and duty are provided, PWM output will start immediately.

Pins at the same device have the same frequency.  If the PWM output number
exceeds the number of channels at the PWM device, the effctive channel_no
is output_no % channel_count.  So with a channel count of 4, output 7 is
assigned to channel 3.  Pins at a certain channel have the same frequency
and duty rate, but may be seperately inverted.

- average=n The average of samples, which are taken and cumulated.  The
            default value is 16.  Averaging by hw is faster than averaging
            in code.

The ADC runs at a clock freq 1.5 MHz.  A single 12 bit conversion takes
8 microseconds.

6765d4bbd6 samd/pin_af: Add the pin af table and its helper functions.
The pin af table is a representation of the MUX table from the data sheet.
It provides information for each pin about the supported device functions.

That information is needed by pin.irq, machine.ADC, machine.PWM,
machine.UART, machine.SPI and machine.I2C.  For each of these, the table
tells for each pin, which device number, af number and pad number is
assigned.  Using the table gives a straight, uniform access to the
information, where the benefit outweights the size of the table, which is
not that large.

The tables are MCU-specific.  It is not required to tell for each board,
which and where each of the above devices is available.  That makes addding
boards easy.

Note: The information for DAC and I2S was not included, since it affects
only a few pins.

- GCLK3: 1 MHz (SAMD21) or 8 MHz (SAMD51) for the µs ticks timer.
- GCLK8: 1 kHz for WDT (SAMD21 only).

If a 32 kHz crystal is present, it will be used as clock source.  Otherwise
the DFLL48M in open-loop mode is used.

GCLK0 for SAM51 can be changed between 48 MHz and 200 MHz.  The specified
range is 96 MHz - 120 MHz.

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.

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).

fdfe4eca74 ports: Always include debug information in the ELF.
For bare metal ARM & xtensa targets, passing -g will make the ELF file
larger but doesn't change the binary size.  However, this means tools like
gdb, addr2line, etc can extract source-level information from the ELF.

Also standardise -ggdb to -g, these produce the exact same ELF file on
arm-none-eabi-gcc and will use DWARF format for all these ports.

81dbea1ce3 shared/readline: Use MP_REGISTER_ROOT_POINTER().
This uses MP_REGISTER_ROOT_POINTER() to register the readline_history root

This also required adding a new MICROPY_READLINE_HISTORY_SIZE config option
since not all ports used the same sized array.

c118b5d0e4 extmod/extmod.mk: Separate out extmod file list from py.mk to extmod.mk.
This separates extmod source files from `py.mk`.  Previously, `py.mk`
assumed that every consumer of the py/ directory also wanted to include
extmod/.  However, this is not the case.  For example, building mpy-cross
uses py/ but doesn't need extmod/.

This commit moves all extmod-specific items from `py.mk` to `extmod.mk` and
explicitly includes `extmod.mk` in ports that use it.

For ports with MICROPY_VFS and MICROPY_PY_IO enabled their configuration
can now be simplified to use the defaults for mp_import_stat and
mp_builtin_open.

This commit makes no functional change, except for the following minor
points:
- the built-in "open" is removed from the minimal port (it previously did
  nothing)
- the duplicate built-in "input" is removed from the esp32 port
- qemu-arm now delegates to VFS import/open
