This board has only 2MiB of flash so the build needs to be reduced in size
to fit. Commit 549448e8bb made all boards
build with -O2 by default (for performance) so this overrides that default.

This is needed because these ports allocate mbedtls data on the MicroPython
heap, and SSL socket objects must be fully cleaned up when they are garbage
collected, to free this memory allocated by mbedtls. As part of this,
gc_sweep_all() will now ensure that the MP_STATE_PORT(mbedtls_memory)
linked-list is fully deallocated on soft reset.

CONFIG_USB was removed in Zephyr v2.7.0 after some Kconfig rework that
made it sufficient to use CONFIG_USB_DEVICE_STACK only.

Updates the Zephyr port to get the UART console device from devicetree
instead of Kconfig. The Kconfig option CONFIG_UART_CONSOLE_ON_DEV_NAME
was removed in Zephyr v2.7.0.

The reboot header was moved to a different path in Zephyr v2.6.0. The
old path was deprecated for two releases (v2.6.0 and v2.7.0) and will no
longer be supported after Zephyr v2.7.0.

As a prerequisite to upgrading to Zephyr v2.7.0, upgrade the minimum
CMake version required for the Zephyr port to 3.20.0.

After changing the bitstream implementation to use the RMT driver in
commit 72d86158121e32bbabaeade08f449d507bf40f9a
("esp32/machine_bitstream.c: Replace with RMT-based driver."), using
multiple `Neopixel` instances shows signal duplication between the
instances (i.e. a `write()` on one instance is written to all instances).
On invocation, the rmt driver configures the GPIO matrix to route the
output signal to the respective GPIO pin. When called for a different
`NeoPixel` instance using a different pin, the new route is established,
but the old route still exists. Now, the RMT output signal is sent to both
pins.
Fix this by setting the standard GPIO output function for the current pin
after uninstalling the RMT driver.

In commit 86ce442607 the '.frozen' entry was
added at the start of sys.path, to allow control over when frozen modules
are searched during import, and retain existing behaviour whereby frozen
was searched before the filesystem.
But Python semantics of sys.path require sys.path[0] to be the directory of
the currently executing script, or ''.
This commit moves the '.frozen' entry to second place in sys.path, so
sys.path[0] retains its correct value (described above).

Save and restore the same duty cycle when the frequency (or frequency
resolution) is changed. This allows a smooth frequency change.
Also update the esp32 PWM quickref to be clearer.
These removed ones are either unused by MicroPython or provided by osapi.h
in the SDK. In particular ets_delay_us() has different signatures for
different versions of the SDK, so best to let it provide the declaration.
Fixes issue #8095.

If MICROPY_PY_SYS_PATH_ARGV_DEFAULTS is enabled (which it is by default)
then sys.path and sys.argv will be initialised and populated with default
values. This keeps all bare-metal ports aligned.

Frozen modules will be searched preferentially, but gives the user the
ability to override this behavior.
This matches the previous behavior where "" was implicitly the frozen
search path, but the frozen list was checked before the filesystem.

This feature is not enabled on any port, it's not in CPython's io module,
and functionality is better suited to the micropython-lib implementation of
pkg_resources.
Default SPI pins are now correctly assigned by machine_hw_spi.c even for S2
and S3. mpconfigboard.h files define defaults with flipped SPI(1) and
SPI(2) to workaround a bug in machine_hw_spi.c - the bug is fixed.

Use IO_MUX pins as defined by ESP IDF in soc/esp32/include/soc/spi_pins.h
ESP32S2 and S3 don't have IO_MUX pins for SPI3, GPIO matrix is always used.
Choose suitable defaults for S2 and S3.
ESP32C3 does not have SPI3 at all. Don't define pin mappings for it.

Use IO_MUX pins as defined by ESP IDF in soc/esp32*/include/soc/spi_pins.h
Alternatively use now deprecated HSPI_IOMUX_PIN_NUM_xxx
(or FSPI_IOMUX_PIN_NUM_xxx for ESP32S2) for compatibility with IDF 4.2
and older.

The index of machine_hw_spi_obj and machine_hw_spi_default_pins arrays is
assigned to 0 for ARG_id==HSPI_HOST and 1 for another SPI. On ESP32S2 and
S3 HSPI_HOST=2 so the first set (idx=0) of default pins is used for
SPI(id=2) aka HSPI/SPI3 and the second set (idx=1) for SPI(id=1) aka
FSPI/SPI2. This makes a misleading mess in MICROPY_HW_SPIxxxx definitions
and it is also in contradiction to the comments around the definitions.
Change the test of ARG_id to fix the order of machine_hw_spi_default_pins.
This change might require adjusting MICROPY_HW_SPIxxxx definitions in
mpconfigboard.h of S2/S3 based boards.

- Move the qspi_xxxx_flash_config.c files to hal.
It turned out that they are less board than flash type specific.
- Change to a common flexspi_flash_config.h header file.
Thanks for the hint, Damien. The DEBUG build got very large recently.
The major difference is, that inline function are now inlined and
not included as a function. That's good and maybe bad. The good thing is,
that the code speed si now close to the final code. It could be worse
in single step debugging. I'll see.
Setting this option caused a new warning and a formatting error
to pop up at different places. Fixed as well.
The ID is read in a single function and used for:
- machine.unique_id()
- Ethernet MAC addresses.
- ...
That facilitates use of other MCU using a different access method for
the ID (e.g. i.MX RT1176).
Just another choice for the PHY interface.
Added: Keyword option phy_clock=LAN.IN or LAN.OUT
to define the source of the 50MHZ clock for the PHY
interface. The RMII clock is not enabled if it
is generated by a PYH board. Constants:
LAN.IN The clock is provided by the PHY board.
LAN.OUT The clock is provided by the MCU board.
The default is LAN.OUT or the value set in mpconfigboard.h, which
is currently set to IN only for the SEEED ARCH MIX board. Usage etc:
lan = LAN(phy_type=LAN.PHY_DP83848, phy_clock=LAN.IN)
The initial problem with a wrong ICMP checksum was caused by
the test code setting a checksum and the HW taking that probably as
the start value and ending up with 0xffff. With a checksum field of 0
set by the test code the HW creates the proper checksum.
Useful for boards without a PHY interface, where that has to be
attached. Like the Seed ARCH MIX board or Vision SOM. Phy drivers
supported so far are:
- KSZ8081
- DP83825
- LAN8720
More to come. Usage e.g.:
lan = LAN(phy_type=LAN.PHY_LAN8720, phy_addr=1)
The default values are those set in mpconfigboard.h.
