Damien George 0c7726a89c all: Use enum instead of bool argument to mp_handle_pending.
This should be a no-op because the enum and bool have the same numeric
value.

Damien George adbdded185 ports: Remove incorrect and unnecessary mp_handle_pending declaration.
In c57aebf790 `mp_handle_pending()` became a
static-inline function.  So these declarations in `mpconfigport.h` are
incorrect and removed by this commit.

Andrew Leech 0e9e66100e mimxrt/machine_uart: Use a wrapper function to handle IRQ idle support.
MicroPython needs to handle the UART idle interrupt, which is not something
that the standard SDK provides.  This was previously fixed by including in
the mimxrt port a modified copy of `fsl_lpuart.c`.

This commit changes how that's done by building the unmodified
`fsl_lpuart.c` directly from the SDK, and using linker wrapping to override
the necessary functions to get at the idle IRQ.  As part of this, the code
is updated to work with the latest SDK.

Damien George 1b2f6e3d1f mimxrt: Increase resolution of RTC to 1/32768 seconds.
Currently the mimxrt port has a resolution of only 1 second for
`machine.RTC().datetime()` and `time.time_ns()`.  This means (among other
things) that it fails the `tests/extmod/time_time_ns.py` test, which
requires requires at least 5ms of resolution.

The underlying RTC hardware is just a 64-bit counter, and the HAL functions
`SNVS_LP_SRTC_GetDatetime()` and `SNVS_LP_SRTC_SetDatetime()` do
conversions between y/m/d/h/m/s and this 64-bit value, which counts at a
rate of 32kHz.

This commit changes the RTC code to access the 64-bit counter directly and
therefore improve resolution of all RTC functions to 1/32768 seconds.

That makes things much simpler because it a lot of places the code wants to
know the number of seconds since the Epoch.  Currently it uses a
combination of `SNVS_LP_SRTC_GetDatetime()` and
`timeutils_seconds_since_epoch()` which converts the 64-bit counter to
date-time and then back to seconds.  Those operations are computationally
expensive.

With this commit, getting the number of seconds since the Epoch is as
simple as reading the 64-bit counter and dividing by 32768.  We can
leverage a lot of the timeutils functions to simplify everything, and make
it similar to other ports like rp2.

Benefits of this change:
- simpler, more efficient code to get/set RTC
- `machine.RTC().datetime()` now has a non-zero value in the last slot,
  being the number of microseconds, and has a resolution of 1/32768 seconds
- `time.time_ns()` now has a resolution of 1/32768 seconds
- the `test/extmod/time_time_ns.py` test now passes

Algy Tynan af88d65e86 mimxrt: Add ALT11 pin mode support for MIMXRT1176.
This adds support for the ALT11 alternate function mode on MIMXRT1176
MCUs, enabling FLEXPWM channels on GPIO_AD pins that were previously
unavailable for PWM use.

Changes:
- Add PIN_AF_MODE_ALT11 enum to pin.h
- Add ALT11 column to MIMXRT1176_af.csv with FLEXPWM mappings
- Enables FLEXPWM1-4 on GPIO_AD_06 through GPIO_AD_21

This change only affects MIMXRT1176-based boards (MIMXRT1170_EVK and
PHYBOARD_RT1170). Other MIMXRT family chips use alternate function
modes ALT0-ALT9 and are not affected.

Tested on MIMXRT1176 hardware with PWM output on GPIO_AD_14
(FLEXPWM3_PWM0_X).

Alon Bar-Lev 2b07661ee6 mimxrt/machine_adc: Support ADC channel groups on rt117x.
The rt117x uses the LPADC peripheral which supports both A-side and B-side
channel inputs, e.g. ADC1_CH1A and ADC1_CH1B.

Previously, only `kLPADC_SampleChannelSingleEndSideA` was being used during
capture, while the pin may be in side B.  The fix in this commit detects
the side based on the pin configuration and sets `sampleChannelMode`
appropriately.

STM32CubeMX shows a conflict of UART5 with ETH MII.
However UART1 can be used with TX and RX on the pin headers.

PLL1Q is reduced from 200 to 100 MHz because it may be used for FDCAN
or SDMMC. FDCAN needs <= 150 MHz, and 100 MHz is enough for an SDCard
connected to pin headers to work reliably.

This commit modifies the Alif port's Makefile to propagate to child make
tasks the number of parallel jobs to run.

On Ubuntu LTS 24.04, building the Alif port passing a parallel jobs
number to make's command line will result in the command emitting this
warning:

make[1]: warning: jobserver unavailable: using -j1.  Add '+' to parent
                  make rule.

And building the two cores' firmware images using one compile job at a

Alessandro Gatti 678dbd26f8 alif/Makefile: Do not hardcode the python interpreter name.
This commit fixes a build issue occurring on systems where the Python
3.x interpreter isn't aliased to 'python' but has a different name
(usually `python3').

The main Linux distribution where this occurs is Ubuntu LTS, where the
Python 3.x interpreter is available as 'python3' since at least two
major versions (so since about five years now).  MicroPython's makefile
environment setup file ('py/mkenv.mk') already defines a variable called
'$(PYTHON)' that defaults to 'python3', so the Makefile was updated to
use that instead of hardcoding the interpreter name.  Without these
changes, building a firmware image on Ubuntu LTS fails with this error:

make: python: No such file or directory
make: *** [Makefile:95: build-ALIF_ENSEMBLE/firmware.toc.bin] Error 127

This also allows overriding the interpreter name to something else if
there's the need to perform tests with different interpreter versions or
the like.

Alessandro Gatti 11861e96a9 nrf/modules/machine/pin: Reduce footprint of pin structures.
This commit performs a few minor changes to the structures used to store
board pin information, in order to reduce the impact on the .rodata
section of the firmware of instances of those structures.

The "pin_obj_t" structure, holding pin information, had an unused
word-sized field ("pull") that isn't used by any of the board
definitions, yet it takes up space in each pin structure being compiled
in the final firmware image.

Images for all available boards were built successfully with this
change, so there should be no unwanted issues arising from shrinking
that structure.

This commit performs a few minor changes to the structures used to store
board pin information, in order to reduce the impact on the .rodata
section of the firmware of instances of those structures.

The pin objects structure ("machine_pin_obj_t") instead has its QSTR
variable holder changed from "qstr" to "qstr_short_t", and some elements
of that structure have been rearranged to remove enough padding bytes
inside structure elements to let the linker allocate less data for

Alessandro Gatti 31deee9060 rp2/machine_pin: Reduce footprint of pin structures.
This commit performs a few minor changes to the structures used to store
board pin information, in order to reduce the impact on the .rodata
section of the firmware of instances of those structures.

The data type used to store the QSTR name of both regular and alternate
function pins ("machine_pin_obj_t" and "machine_pin_af_obj_t") is changed
from "qstr" to "qstr_short_t", that is able to store the same name string
index but in half the size.

Alessandro Gatti fb8ecaecf5 renesas-ra/pin: Reduce footprint of pin structures.
This commit performs a few minor changes to the structures used to store
board pin information, in order to reduce the impact on the .rodata
section of the firmware of instances of those structures.

The pin objects structure ("machine_pin_obj_t") instead has its QSTR
variable holder changed from "qstr" to "qstr_short_t", and some elements
of that structure have been rearranged to remove enough padding bytes
inside structure elements to let the linker allocate less data for
instances of that structure.

Alessandro Gatti 049cdd0dd3 cc3200/mods/pybpin: Reduce footprint of AF pin structures.
This commit performs a minor change to the "pin_af_t" structure,
changing the data type used to store alternate function pin name QSTRs
in order to have a smaller impact on the .rodata section of the
firmware.

The data type used to store the QSTR name of the pin is changed from
"qstr" to "qstr_short_t", that is able to store the same name string
index but in half the size.

Other pin-related structures in the port that also store QSTRs do not
benefit from a narrower data type, as their members are mostly
word-aligned and thus the linker is forced to insert padding bytes
between entries.

The implementation uses the object based capabilities, which avoids
complication about different flash block sizes.  The ROM partition is
placed between the text and writable filesystem sections, and the latter
size is unchanged.  VfsRom sizes are:
- NRF51x22: 12K
- NRF52832: 128K
- NRF52840: 256K
- NRF9160:  256K

Use frozen `_boot.py` to set up and mount the filesystem, replacing a mix
of C-Code and Python code.  The mkfs part has been simplified to save code.

Tested with Microbit and Arduino Nano Connect.

The ROM partition is taken from the last part of the flash text section, so
the existing writable filesystem is untouched.  VfsRom file system sizes:
- EK_RA4M1: 12K
- RA4M1_CLICKER: 12k
- EK_RA4W1: 64k
- EK_RA6M1: 64k
- EK_RA6M2: 256k
- VK_RA6M5: 384k
- ARDUINO_PORTENTA_C33: 256k

Tested with Weact RA4M1 core board with EK_RA4M1 firmware and EK_RA6M2.

robert-hh c07b178dbd samd: Add support for VfsRom filesystem for SAMD21 and SAMD51.
The flash driver is update to support the new `mp_vfs_rom_ioctl()`
function, and the buffer protocol is added to `samd_flash_type` (it is
needed for VfsRom on devices without external flash).

For SAMD21, only boards with external SPI flash have VfsRom enabled, due
to size constraints.  For such boards, the VfsRom filesystem has a size of
12k and is placed at the upper end of the flash.  The `onewire`, `ds18x20`
and `dht` drivers have been removed from frozen bytecode as they can be
placed into the VfsRom files when needed.

For SAMD51, the VfsRom filesystem has a default size of 64k for SAMD51x19
and 256K for SAMD51x20.  It is placed at the upper end of the flash.
For boards with external SPI flash, the code size is reduced from 496K to
432K.  If that is not sufficient for some boards or configurations, it can
be changed for each board or board variant.

Tested with ADAFRUIT_ITSYBITSY_M0_EXPRESS, ADAFRUIT_ITSYBITSY_M4_EXPRESS,
SPARKFUN_SAMD51_THING_PLUS, SEEED_XIAO_SAMD21, SAMD_GENERIC_D51X19, and
SAMD_GENERIC_D51X20.

robert-hh b857a9131e mimxrt: Add support for VfsRom filesystem.
The default size for the ROM partition is 256k, and it is placed in flash
between the text and writable vfs sections.  Its size can be changed in
`mpconfigboard.mk` by defining `MICROPY_HW_ROMFS_BYTES` to a different
value, but it must not be smaller than a single sector.

The MIMXRT1170_EVK and SEEED ARCH MIX ROMFS boards use a larger size of
512kB.  ROMFS support is disabled for MIMXRT1050_EVKB due to issues with
Hyperflash.

The extents of the ROM partition are defined by the linker-level symbols
`_micropy_hw_romfs_part0_start` and `_micropy_hw_romfs_part0_size`,
following existing ports.

Alessandro Gatti d44685e103 unix/mpconfigport: Enable natmod loading for RISC-V builds.
This commit lets the Unix port load native modules when built for both
RV32 and RV64.

Since RV64 doesn't have a native emitter, the new native code loading
configuration settings have been used to allow such a feature.  RV32 is
fully supported by the native emitter framework but the emitter wasn't
enabled for Unix builds (and therefore no natmod support).

RV64 builds have been tested on QEMU and on a MilkV-Duo board, and
whilst RV32 isn't really tested, its native code loading functionality
is routinely tested both on bare-metal QEMU and on microcontroller
boards.  Since the code for RV64 under Unix and RV32 is essentially the
same, having RV64 working is a strong indicator that RV32 will work too.
