Jim Mussared 23109988c2 stm32/uart: Allow static IRQ handler registration.
This will allow the HCI UART to use a non-heap mp_irq_obj_t, which avoids
needing to make a root pointer for it.

Damien George 3ff7079277 lib/utils/mpirq: Add mp_irq_init func, and clean up unused init method.
mp_irq_init() is useful when the IRQ object is allocated by the caller.

The mp_irq_methods_t.init method is not used anywhere so has been removed.

Zoltán Vörös 27767aafa2 lib/libm_dbl: Add round.c source code.
This code is imported from musl, to match existing code in libm_dbl.

The file is also added to the build in stm32/Makefile.  It's not needed by
the core code but, similar to c5cc64175b,
allows round() to be used by user C modules or board extensions.

Thorsten von Eicken 3e758ef235 lib/mbedtls_errors: Add code to patch mbedtls for shortened error strs.
The file `mbedtls_errors/mp_mbedtls_errors.c` can be used instead of
`mbedtls/library/error.c` to give shorter error strings, reducing the build
size of the error strings from about 12-16kB down to about 2-5kB.

David Lechner 77ed6f69ac tools/uncrustify: Enable more opts to remove space between func and '('.
With only `sp_func_proto_paren = remove` set there are some cases where
uncrustify misses removing a space between the function name and the
opening '('.  This sets all of the related options to `force` as well.

Jim Mussared 710426024a all: Factor gchelper code to one place and use it for unix & ARM ports.
No functionality change is intended with this commit, it just consolidates
the separate implementations of GC helper code to the lib/utils/ directory
as a general set of helper functions useful for any port.  This reduces
duplication of code, and makes it easier for future ports or embedders to
get the GC implementation correct.

Ports should now link against gchelper_native.c and either gchelper_m0.s or
gchelper_m3.s (currently only Cortex-M is supported but other architectures
can follow), or use the fallback gchelper_generic.c which will work on
x86/x64/ARM.

The gc_helper_get_sp function from gchelper_m3.s is not really GC related
and was only used by cc3200, so it has been moved to that port and renamed
to cortex_m3_get_sp.

Damien George e08ca78f40 py/stream: Remove mp_stream_errno and use system errno instead.
This change is made for two reasons:

1. A 3rd-party library (eg berkeley-db-1.xx, axtls) may use the system
   provided errno for certain errors, and yet MicroPython stream objects
   that it calls will be using the internal mp_stream_errno.  So if the
   library returns an error it is not known whether the corresponding errno
   code is stored in the system errno or mp_stream_errno.  Using the system
   errno in all cases (eg in the mp_stream_posix_XXX wrappers) fixes this
   ambiguity.

2. For systems that have threading the system-provided errno should always
   be used because the errno value is thread-local.

For systems that do not have an errno, the new lib/embed/__errno.c file is
provided.

stijn 84fa3312cf all: Format code to add space after C++-style comment start.
Note: the uncrustify configuration is explicitly set to 'add' instead of

Jim Mussared f46782dde9 mimxrt: Add new, minimal port to NXP i.MX RT series CPUs.
This is an extremely minimal port to the NXP i.MX RT, in the style of the
SAMD port  It's largely based on the TinyUSB mimxrt implementation, using
the NXP SDK.  It currently supports the Teensy 4.0 board with a REPL over
the USB-VCP interface.

This commit also adds the NXP SDK submodule (also from TinyUSB) to
lib/nxp_driver.

Note: if you already have the tinyusb submodule initialized recursively you
will need to run the following as the tinyusb sub-submodules have been
rearranged (upstream):

    git submodule deinit lib/tinyusb
    rm -rf .git/modules/lib/tinyusb
    git submodule update --init lib/tinyusb

Damien George abe2caf6df py/scheduler: Move clearing of kbd traceback to mp_keyboard_interrupt.
This is a more logical place to clear the KeyboardInterrupt traceback,
right before it is set as a pending exception.  The clearing is also
optimised from a function call to a simple store of NULL.

Damien George 9efb36bfa6 py/scheduler: Move mp_keyboard_interrupt from lib/utils to py core.
This function is tightly coupled to the state and behaviour of the

Damien George 5a91cd9ff3 lib/utils/pyexec: Handle pending exceptions after disabling kbd intrs.
Pending exceptions would otherwise be handled later on where there may not
be an NLR handler in place.

A similar fix is also made to the unix port's REPL handler.

Fixes issues #4921 and #5488.

odewdney b51a2c266a lib/utils: Change default value of pyexec_mode_kind to 0 to put in bss.
By simply reordering the enums for pyexec_mode_kind_t it eliminates a data
variable which costs ROM to initialise it.  And the minimal build now has
nothing in the data section.

It seems the compiler is smart enough so that the generated code for
if-logic which tests these enum values is unchanged.

Yonatan Goldschmidt 853aaa06f2 lib/mp-readline: Add word-based move/delete EMACS key sequences.
This commit adds backward-word, backward-kill-word, forward-word,
forward-kill-word sequences for the REPL, with bindings to Alt+F, Alt+B,
Alt+D and Alt+Backspace respectively.  It is disabled by default and can be
enabled via MICROPY_REPL_EMACS_WORDS_MOVE.

Further enabling MICROPY_REPL_EMACS_EXTRA_WORDS_MOVE adds extra bindings
for these new sequences: Ctrl+Right, Ctrl+Left and Ctrl+W.

The features are enabled on unix micropython-coverage and micropython-dev.

Yonatan Goldschmidt dce590c29d lib/mp-readline: Add an assert() to catch buffer overflows.
During readline development, this function may receive bad `pos` values.
It's easier to understand the assert() failing error than to have a "stack
smashing detected" message.

Yonatan Goldschmidt 61d2b40ad5 lib/utils/pyexec: Introduce MICROPY_REPL_INFO, wrap debug prints in it.
For the 3 ports that already make use of this feature (stm32, nrf and
teensy) this doesn't make any difference, it just allows to disable it from
now on.

For other ports that use pyexec, this decreases code size because the debug
printing code is dead (it can't be enabled) but the compiler can't deduce
that, so code is still emitted.

Damien George af20c2ead3 py: Add global default_emit_opt variable to make emit kind persistent.
mp_compile no longer takes an emit_opt argument, rather this setting is now
provided by the global default_emit_opt variable.

Now, when -X emit=native is passed as a command-line option, the emitter
will be set for all compiled modules (included imports), not just the
top-level script.

In the future there could be a way to also set this variable from a script.

Fixes issue #4267.
