Jim Mussared 7d40317a4a stm32: Add a default implementation of pyb.country.
This is for boards without networking support so that the default boot.py
continues to work.

Also update boot.py to use network.country and network.hostname instead.

Jim Mussared bad0098a49 stm32: Update to use the open-source lib version of cyw43-driver.
This removes the previous WiFi driver from drivers/cyw43 (but leaves behind
the BT driver), and makes the stm32 port (i.e. PYBD and Portenta) use the
new "lib/cyw43-driver" open-source driver already in use by the rp2 port.

Jim Mussared 6207b605ce esp8266: Use extmod/modnetwork.c instead of port-specific version.
Rather than duplicating the implementation of `network`, this allows
ESP8266 to use the shared one in extmod.  In particular this gains access
to network.hostname and network.country.

Other than adding these two methods, there is no other user-visible change.

Jim Mussared a377302623 extmod/modnetwork: Add network.hostname() and network.country().
This provides a standard interface to setting the global networking config
for all interfaces and interface types.

For ports that already use either a static hostname (mimxrt, rp2) they will
now use the configured value. The default is configured by the port
(or optionally the board).

For interfaces that previously supported .config(hostname), this is still
supported but now implemented using the global network.hostname.

Similarly, pyb.country and rp2.country are now deprecated, but the methods
still exist (and forward to network.hostname).

Because ESP32/ESP8266 do not use extmod/modnetwork.c they are not affected
by this commit.

robert-hh 4160ec087b samd/mcu: Set the SAMD21 us-counter to 2 MHz for better resolution.
It turned out that the result of calling ticks_us() was always either odd
or even, depending on some internal state during boot.  So the us-counter
was set to a 2 MHz input and the result shifted by 1.  The counting period
is still long enough, since internally a (now) 63 bit value is used for us.

robert-hh 76cf98c35b samd/mcu: Implement a hardware seed for the SAMD21 random module.
By using the phase jitter between the DFLL48M clock and the FDPLL96M clock.
Even if both use the same reference source, they have a different jitter.
SysTick is driven by FDPLL96M, the us counter by DFLL48M.  As a random
source, the us counter is read out on every SysTick and the value is used
to accumulate a simple multiply, add and xor register.  According to tests
it creates about 30 bit random bit-flips per second.  That mechanism will
pass quite a few RNG tests, has a suitable frequency distribution and
serves better than just the time after boot to seed the PRNG.

robert-hh 7e0b1bc95d samd/mcu: Use the FDPLL96M clock for the SAMD21 CPU.

DFLL48M and FDPLL96M.

os.dupterm is generally useful, but can still be disabled by a board if
needed.  hashlib.sha1 requires mbedtls for the implementation, but that's
always available (due to ucryptolib's requirements).  The entire hashlib
module can still be disabled by an individual board if needed.

robert-hh de1f1dd164 shared/runtime/softtimer: Use consistently the same clock source.
Before, both uwTick and mp_hal_ticks_ms() were used as clock source.  That
assumes, that these two are synchronous and start with the same value,
which may be not the case for all ports.  If the lag between uwTick and
mp_hal_ticks_ms() is larger than the timer interval, the timer would either
rush up until the times are synchronous, or not start until uwTick wraps
over.

As suggested by @dpgeorge, MICROPY_SOFT_TIMER_TICKS_MS is now used in
softtimer.c, which has to be defined in a port's mpconfigport.h with
the variable that holds the SysTick counter.

Note that it's not possible to switch everything in softtimer.c to use
mp_hal_ticks_ms() because the logic in SysTick_Handler that schedules
soft_timer_handler() uses (eg on mimxrt) the uwTick variable directly
(named systick_ms there), and mp_hal_ticks_ms() uses a different source
timer.  Thus it is made fully configurable.

Damien George 0afe60b876 rp2/rp2_pio: Track use of PIO resources and free them on soft reset.
Prior to this commit, on Pico W (where the CYW43 driver is enabled) the PIO
instruction memory was not released on soft reset, so using PIO after a
soft reset would eventually (after a few soft resets) lead to ENOMEM when
allocating a PIO program.

This commit fixes that by tracking the use of PIO memory by this module and
freeing it on soft reset.

Similarly, use of the state machines themselves are tracked and released on
soft reset.

David Lechner 3446d440f6 shared/runtime/gchelper: Drop cpu directive from ARM asm helpers.
This drops the `.cpu` directive from the ARM gchelper_*.s files.  Having
this directive breaks the linker when targeting older CPUs (e.g. `-mthumb
-mthumb-interwork` for `-mcpu=arm7tdmi`).  The actual target CPU should be
determined by the compiler options.

The exact CPU doesn't actually matter, but rather the supported assembly
instruction set.  So the files are renamed to *_thumb1.s and *thumb2.s to
indicate the instruction set support instead of the CPU support.

Add support for various SPI-based ethernet chips (W5500, KSZ8851SNL,
DM9051) to the ESP32 port.  This leverages the existing support in ESP-IDF
for these chips -- which configures these chips in "MAC raw" mode -- and
the existing support for network.LAN in the ESP32 port.  In particular,
this doesn't leverage the wiznet5k support that is used on the rp2 and
stm32 ports (because that's for native use of lwIP).

Tested on the POE Featherwing (with the SJIRQ solder jumper bridged) and a
ESP32-S3 feather.

A note about the interrupt pin: The W5500 implementation within ESP-IDF
relies on hardware interrupt, and requires the interrupt pin from the W5500
to be wired to a GPIO.  This is not the case by default on the Adafruit
Ethernet FeatherWing, which makes it not directly compatible with this
implementation.

- sys.path contains entries for the local file system (default), and
- files are imported by boot.py or main.py from frozen bytecode of the file
  system (common) and the file system contains many files, like 100.

In that case the board is very busy with scanning LFS, and registering the
USB interface seems to time out.  This commit fixes this by allowing the
USB to make progress during filesystem reads.

Also switch existing MICROPY_EVENT_POLL_HOOK uses in this file to
MICROPY_EVENT_POLL_HOOK_FAST now that the latter macro exists.

Paul Grayson b208cf23e2 rp2/mphalport: Change order of pin operations to prevent glitches.
When switching from a special function like SPI to an input or output,
there was a brief period after the function was disabled but before the
pin's I/O state was configured, in which the state would be poorly defined.
This fixes the problem by switching off the special function after fully
configuring the I/O state.

Fixes #10226.

Felix Dörre 439298be15 rp2: Fix lightsleep to work with interrupts and cyw43 driver.
This commit prevents the device from "hanging" when using lightsleep while
the WiFi chip is active.

Whenever the WiFi chip wants to interrupt the microcontroller to notify it
for a new package, it sets the CYW43_PIN_WL_HOST_WAKE pin to high,
triggering an IRQ.  However, as polling the chip cannot happen in an
interrupt handler, it subsequently notifies the pendsv-service to do a poll
as soon as the interrupt handler ended.  In order to prevent a new
interrupt from happening immediately afterwards, even before the poll has
run, the IRQ handler disables interrupts from the pin.

The first problem occurs, when a WiFi package arrives while the main loop
is in cyw43-code.  In order to prevent concurrent access of the hardware,
the network code blocks pendsv from running again while entering lwIP code.

The same holds for direct cyw43 code (like changing the cyw43-gpios, i.e.
the LED on the Pico W).  While the pendsv is disabled, interrupts can still
occur to schedule a poll (and disable further interrupts), but it will not
run.  This can happen while the microcontroller is anywhere in rp2040 code.

In order to preserve power while waiting for cyw43 responses,
cyw43_configport.h defines CYW43_DO_IOCTL_WAIT and
CYW43_SDPCM_SEND_COMMON_WAIT to __WFI().  While this might work in most
cases, there are 2 edge cases where it fails:
- When an interrupt has already been received by the cyw43 stack, for
  example due to an incoming ethernet packet.
- When the interrupt from the cyw43 response comes before the
  microcontroller entered the __WFI() instruction.

When that happens, wfi will just block forever as no further interrupts are
received.  The only way to safely use wfi to wake up from an interrupt is
inside a critical section, as this delays interrupts until the wfi is
entered, possibly resuming immediately until interrupts are reenabled and
the interrupt handler is run.  Additionally this critical section needs to
check whether the interrupt has already been disabled and pendsv was
triggered, as in such a case, wfi can never be woken up, and needs to be
skipped, because there is already a package from the network chip waiting.
Note that this turns cyw43_yield into a nop (and thereby the cyw43-loops
into busy waits) from the second time onwards, as after the first call, a
pendsv request will definitely be pending.  More logic could be added, to
explicitly enable the interrupt in this case.

Regarding lightsleep, this code has a similar problem.  When an interrupt
occurs during lightsleep, the IRQ and pendsv handler and thereby poll are
run immediately, with the clocks still disabled, causing the SPI transfers
to fail.  If we don't want to add complex logic inside the IRQ handler we
need to protect the whole lightsleep procedure form interrupts with a
critical section, exiting out early if an interrupt is pending for whatever
reason.  Only then we can start to shut down clocks and only enable
interrupts when the system is ready again.  Other interrupt handlers might
also be happy, that they are only run when the system is fully operational.

Tested on a Pico W, calling machine.lightsleep() within an endless loop and
pinging from the outside.

This was previously implemented by adding additional members to the

the new object type slots mechanism. The way this works is also not
supported on GCC 8.x and below.

Instead replace it with the type protocol, which is a much simpler way of
achieving the same thing.

This affects the WizNet (in non-LWIP mode) and Nina NIC drivers.

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.
