And put back our magic number, because our bytecode format differs
from upstream
drop btree & framebuf natmods, they had additional problems I didn't
want to fix right now.
This ensures the same number of cycles are used for LED on and LED off in
the PIO 1Hz example. It's also possible to swap the first set() and the
irq() to avoid using an extra instruction, but this tutorial is a good
example of how to calculate the cycles.

This shows how ports can add their own custom types/classes.
It is part of the unix coverage build, so we can use it for tests too.

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.
Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
The goal here is to remove a slot (making way to turn make_new into a slot)
as well as reduce code size by the ~40 references to mp_identity_getiter
and mp_stream_unbuffered_iter.
This introduces two new type flags:
- MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the
type is "iternext", and should use the identity getiter.
- MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer
to a mp_getiter_iternext_custom_t instance, which then defines both
getiter and iternext.
And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This
means that the type should use the identity getiter, and
mp_stream_unbuffered_iter as iternext.
Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give
the default case where "iter" is "getiter".

This will always have the maximum/minimum size of a mp_obj_type_t
representation and can be used as a member in other structs.
Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
The buffer protocol type only has a single member, and this existing layout
creates problems for the upcoming split/slot-index mp_obj_type_t layout
optimisations.
If we need to make the buffer protocol more sophisticated in the future
either we can rely on the mp_obj_type_t optimisations to just add
additional slots to mp_obj_type_t or re-visit the buffer protocol then.
This change is a no-op in terms of generated code.

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).

Binaries built using the Make build system now no longer appear in the
working directory of the build, but rather in the build directory. Thus
some paths had to be adjusted.
This uses MP_REGISTER_ROOT_POINTER() to register the readline_history root
pointer array used by shared/readline.c and removes the registration from
all mpconfigport.h files.
This also required adding a new MICROPY_READLINE_HISTORY_SIZE config option
since not all ports used the same sized array.

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.

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.

The following changes are made:
- If MICROPY_VFS is enabled then mp_vfs_import_stat and mp_vfs_open are
automatically used for mp_import_stat and mp_builtin_open respectively.
- If MICROPY_PY_IO is enabled then "open" is automatically included in the
set of builtins, and points to mp_builtin_open_obj.
This helps to clean up and simplify the most common port configuration.

F-strings, new machine.I2S class, ESP32-C3 support and LEGO_HUB_NO6 board
This release of MicroPython adds support for f-strings (PEP-498), with a
few limitations compared to normal Python. F-strings are essentially
syntactic sugar for "".format() and make formatting strings a lot more
convenient. Other improvements to the core runtime include pretty printing
OSError when it has two arguments (an errno code and a string), scheduling
of KeyboardInterrupt on the main thread, and support for a single argument
to the optimised form of StopIteration.
In the machine module a new I2S class has been added, with support for
esp32 and stm32 ports. This provides a consistent API for transmit and
receive of audio data in blocking, non-blocking and asyncio-based
operation. Also, the json module has support for the "separators" argument
in the dump and dumps functions, and framebuf now includes a way to blit
between frame buffers of different formats using a palette. A new,
portable machine.bitstream function is also added which can output a stream
of bits with configurable timing, and is used as the basis for driving
WS2812 LEDs in a common way across ports.
There has been some restructuring of the repository directory layout, with
all third-party code now in the lib/ directory. And a new top-level
directory shared/ has been added with first-party code that was previously
in lib/ moved there.
The docs have seen further improvement with enhancements and additions to
the rp2 parts, as well as a new quick reference for the zephyr port.
The terms master/slave have been replaced with controller/peripheral,
mainly relating to I2C and SPI usage. And u-module references have been
replaced with just the module name without the u-prefix to help clear up
the intended usage of modules in MicroPython.
For the esp8266 and esp32 ports, hidden networks are now included in WLAN
scan results. On the esp32 the RMT class is enhanced with idle_level and
write_pulses modes. There is initial support for ESP32-C3 chips with
GENERIC_C3 and GENERIC_C3_USB boards.
The javascript port has had its Makefile and garbage collector
implementation reworked so it compiles and runs with latest the Emscripten
using asyncify.
The mimxrt port sees the addition of hardware I2C and SPI support, as well
as some additional methods to the machine module. There is also support
for Hyperflash chips.
The nrf port now has full VFS storage support, enables source-line on
traceback, and has .mpy features consistent with other ports.
For the rp2 port there is now more configurability for boards, and more
boards added.
The stm32 port has a new LEGO_HUB_NO6 board definition with detailed
information how to get this LEGO Hub running stock MicroPython. There is
also now support to change the CPU frequency on STM32WB MCUs. And USBD_xxx
descriptor options have been renamed to MICROPY_HW_USB_xxx.

This commit removes all parts of code associated with the existing
MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE optimisation option, including the
-mcache-lookup-bc option to mpy-cross.
This feature originally provided a significant performance boost for Unix,
but wasn't able to be enabled for MCU targets (due to frozen bytecode), and
added significant extra complexity to generating and distributing .mpy
files.
The equivalent performance gain is now provided by the combination of
MICROPY_OPT_LOAD_ATTR_FAST_PATH and MICROPY_OPT_MAP_LOOKUP_CACHE (which has
been enabled on the unix port in the previous commit).
It's hard to provide precise performance numbers, but tests have been run
on a wide variety of architectures (x86-64, ARM Cortex, Aarch64, RISC-V,
xtensa) and they all generally agree on the qualitative improvements seen
by the combination of MICROPY_OPT_LOAD_ATTR_FAST_PATH and
MICROPY_OPT_MAP_LOOKUP_CACHE.
For example, on a "quiet" Linux x64 environment (i3-5010U @ 2.10GHz) the
change from CACHE_MAP_LOOKUP_IN_BYTECODE, to LOAD_ATTR_FAST_PATH combined
with MAP_LOOKUP_CACHE is:
diff of scores (higher is better)

This shows that the new optimisations are at least as good as the existing
inline-bytecode-caching, and are sometimes much better (because the new
ones apply caching to a wider variety of map lookups).
The new optimisations can also benefit code generated by the native
emitter, because they apply to the runtime rather than the generated code.
The improvement for the native emitter when LOAD_ATTR_FAST_PATH and
MAP_LOOKUP_CACHE are enabled is (same Linux environment as above):

In summary, compared to MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE, the new
MICROPY_OPT_LOAD_ATTR_FAST_PATH and MICROPY_OPT_MAP_LOOKUP_CACHE options:
- are simpler;
- take less code size;
- are faster (generally);
- work with code generated by the native emitter;
- can be used on embedded targets with a small and constant RAM overhead;
- allow the same .mpy bytecode to run on all targets.
See #7680 for further discussion. And see also #7653 for a discussion
about simplifying mpy-cross options.

* modframebuf: _mp_framebuf_p_t is not "really" a protocol, but the
QSTR assignment caused problems when building as a dynamic module
* modure: str_index_to_ptr is not in the natmod API, disable URE match
spans when dynamic. mp_obj_len() is a bugfix, we should throw here
if the object is not string-like
* moduzlib: Correct paths to uzlib headers & sources. this relative
path (from moduzlib.c to the referenced file) works in all cases,
the other only worked from ports/PORTNAME.
* dynruntime: Handle 2-arg m_malloc, assert_native_inited, add a
micropythonish mp_arg_check_num_mp, fix mp_raise_msg to use dumb
strings, add mp_raise_arg1
* nativeglue: ad assert_native_inited
* translate: MP_ERROR_TEXT evaluates to its argument for DYNRUNTIME
* mpy-tool: A straggling magic number change
* mpy_ld: Have to renumber manually after dynruntime change
* import_mpy_native_gc.py: Update copy of features0 baked into this test
The PIO state machines on the RP2040 have 4 word deep TX and RX FIFOs. If
you only need one direction, you can "merge" them into either a single 8
word deep TX or RX FIFO.
We simply add constants to the PIO object, and set the appropriate bits in
`shiftctrl`.
Resolves#6854.

There were a few changes that had broken this example, specifically
2cdf1d25f5 removed file.c from ports/unix.
And (at least for MacOS) mp_state_ctx must be placed in the BSS with
-fno-common so it is visible to the linker.

It's a bit of a pitfall with user C modules that including them in the
build does not automatically enable them. This commit changes the docs and
examples for user C modules to encourage writers of user C modules to
enable them unconditionally. This makes things simpler and covers most use
cases.
See discussion in issue #6960, and also #7086.

The "word" referred to by BYTES_PER_WORD is actually the size of mp_obj_t
which is not always the same as the size of a pointer on the target
architecture. So rename this config value to better reflect what it
measures, and also prefix it with MP_.
For uses of BYTES_PER_WORD in setting the stack limit this has been
changed to sizeof(void *), because the stack usually grows with
machine-word sized values (eg an nlr_buf_t has many machine words in it).

This commit adds a new port "rp2" which targets the new Raspberry Pi RP2040
microcontroller.
The build system uses pure cmake (with a small Makefile wrapper for
convenience). The USB driver is TinyUSB, and there is a machine module
with most of the standard classes implemented. Some examples are provided
in the examples/rp2/ directory.
Work done in collaboration with Graham Sanderson.

This widens the characteristic/descriptor flags to 16-bit, to allow setting
encryption/authentication requirements.
Sets the required flags for NimBLE and btstack implementations.
The BLE.FLAG_* constants will eventually be deprecated in favour of copy
and paste Python constants (like the IRQs).

Add working example code to provide a starting point for users with files
that they can just copy, and include the modules in the coverage test to
verify the complete user C module build functionality. The cexample module
uses the code originally found in cmodules.rst, which has been updated to
reflect this and partially rewritten with more complete information.
