These micros don't have full SDMMC host support, but they can initialise
the SDCard in SPI mode.
A bit limited on C3 and C6 as they only have one host SPI peripheral.

Previously ESP32-S3 SDMMC could only use fixed pin assignments, however the
ESP-IDF defaults don't match common boards. The chip also supports using
GPIO Matrix to assign any pin.

Not enabled by default on any board. For a board to enable ROMFS it must:
- Add `#define MICROPY_VFS_ROM (1)` to its `mpconfigboard.h` file.
- Add a FLASH_ROMFS partition to the linker script and expose the partition
with:
_micropy_hw_romfs_start = ORIGIN(FLASH_ROMFS);
_micropy_hw_romfs_size = LENGTH(FLASH_ROMFS);

Not enabled by default on any board. A board can enable a ROMFS partition
by defining `MICROPY_HW_ROMFS_BYTES` in its `mpconfigboard.h` file. For
example:
#define MICROPY_HW_ROMFS_BYTES (128 * 1024)
The ROMFS partition is placed at the end of the flash allocated for the
firmware, giving less space for the firmware. It then lives between the
firmware and the read/write filesystem.

This commit implements `vfs.rom_ioctl()` to query, erase and write both
internal and external flash, depending on how the board configures its
flash memory.
A board can configure ROM as follows.
To use internal flash memory:
#define MICROPY_HW_ROMFS_ENABLE_INTERNAL_FLASH (1)
To use external flash memory (QSPI memory mapped):
#define MICROPY_HW_ROMFS_ENABLE_EXTERNAL_QSPI (1)
#define MICROPY_HW_ROMFS_QSPI_SPIFLASH_OBJ (&spi_obj)
Then the partition must be defined as symbols in the linker script:
_micropy_hw_romfs_part1_start
_micropy_hw_romfs_part1_size
And finally the partition needs to be enabled:
#define MICROPY_HW_ROMFS_ENABLE_PART1 (1)
There's support for a second, optional partition via:
_micropy_hw_romfs_part2_start
_micropy_hw_romfs_part2_size
#define MICROPY_HW_ROMFS_ENABLE_PART1 (1)

This commit introduces the ability to obtain a list of stations
connected to the device when in soft-AP mode.
A new parameter ("stations") to pass to WLAN.status is supported,
returning a tuple of (bssid, ipv4) entries, one per connected station.
An empty tuple is returned if no stations are connected, and an
exception is raised if an error occurred whilst building the python
objects to return to the interpreter.
Documentation is also updated to cover the new parameter.
This fixes#5395.

For a given MicroPython firmware/executable it can be sometimes important
to know how it was built, which variant/board configuration it came from.
This commit adds a new field `sys.implementation._build` that can help
identify the configuration that MicroPython was built with.
For now it's either:
* <VARIANT> for unix, webassembly and windows ports
* <BOARD>-<VARIANT> for microcontroller ports (the variant is optional)
In the future additional elements may be added to this string, separated by
a hyphen.
Resolves issue #16498.

Changes are:
- Add the RX/TX pins to the table. In most cases these are the D0/D1 pins.
- Document the ability for the instantiation of the default devices without
submitting ID or pins.
- Improve the example script creating the pin list to show multiple name
assigments to the same pin.
- Fix errors in the pinout document.

If a board configures a default I2C instance and/or SCL/SDA pins, then
these no longer need to be given in the constructor. This allows the user
to easily construct the default I2C instance via `machine.I2C()` and that

This change allows tuples to be passed as the prefix/suffix argument to the
`str.startswith()` and `str.endswith()` methods. The methods will return
`True` if the string starts/ends with any of the prefixes/suffixes in the
tuple.
Also adds full support for the `start` and `end` arguments to both methods
for compatibility with CPython.
Tests have been updated for the new behaviour.

This commit gives the option to not pass an I2C Bus ID when creating a
machine I2C object. If the ID is not provided, the default bus ID (which
is `PICO_DEFAULT_I2C`) is used.
This allows users to simply declare an I2C object with `machine.I2C()`
without passing any arguments, thus creating an object with the default I2C
ID, SCL, and SDA.

The mantissa parsing code uses a floating point variable to accumulate
digits. Using an `mp_float_uint_t` variable instead and casting to
`mp_float_t` at the very end reduces code size. In some cases, it also
improves the rounding behaviour as extra digits are taken into account
by the int-to-float conversion code.
An extra test case handles the special case where mantissa overflow occurs
while processing deferred trailing zeros.
