Adds the ability to use PSRAM and non-contiguous memory.
Example usage, add this to dts overlay:
/ {
heap_psram {
compatible = "micropython,heap";
size = <DT_SIZE_M(4)>;
memory-region = <&psram>;
};
heap_sram1 {
compatible = "micropython,heap";
size = <DT_SIZE_K(140)>;
memory-region = <&sram1>;
};
};

This commit fixes a regression introduced in 1b92bda, where a new architecture was added to mpy-cross but it had no matching native emitter exists. The result was that the architecture emitter entry point would be correctly calculated according to the native architecture index, but if the emitters entry points table was not updated to match the new number of architectures an out of bound access may be performed. Unfortunately adding RV64IMC shifted the debug emitter index further down the table, and that table wasn't updated to reflect the lack of an emitter for RV64. Adding a NULL entry there would cause a NULL pointer access as there was no need to perform any check about the emitter entry point function's validity until now.

This commit adds a new workflow step to the CI, to test the debug emitter provided by mpy-cross. The checks being done are limited to make sure that the debug emitter does not crash and emits opcodes for a simple test file that is guaranteed to work for all configurations.

Break the FS and HS initialization routines out into separate functions, and call them as necessary from the TinyUSB or STM USB helper functions. Signed-off-by: Damien George <damien@micropython.org>
This commit fixes the initialization sequence for TinyUSB when enabled on the stm32 port: - Following other ports, `mp_usbd_init()` should be called just after running `boot.py`, to give the user a chance to configure USB. - Hardware initialization (via `pyb_usbd_init()`) should only occur once, the first time TinyUSB is started up. This is achieved by adding a hook to the shared TinyUSB bindings to call `pyb_usbd_init()`, and only do the hardware init if TinyUSB was not already initialized. Also, `pyb_usbd_init()` is renamed `mp_usbd_ll_init()` to make it match with the rest of the stared TinyUSB binding code. Signed-off-by: Damien George <damien@micropython.org>

This was necessary to un-wedge the USJ TX path on ESP32-P4, I think because the bootloader prints a lot on this chip. I think it might be possible to hit it on other chips, though. The implementation is based on the ESP-IDF driver, which will always add an extra flush when the TXFIFO is empty in case the host is expecting a ZLP. This work was funded through GitHub Sponsors.

Convert the stm32 port from the old `MICROPY_EVENT_POLL_HOOK` macro to use the new `mp_event_wait_xxx()` functions in conjunction with `MICROPY_INTERNAL_WFE`. This change should be functionally equivalent to the existing behaivour because `mp_event_wait_ms()` and `mp_event_wait_indefinite()` are equal to `mp_handle_pending(true); __WFI()`, which is what `MICROPY_EVENT_POLL_HOOK` was. Note that the `CYW43_EVENT_POLL_HOOK` macro needed to be overridden, otherwise it would just call `mp_event_handle_nowait()` which would create power hungry busy loops.

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.

The `builtins.help` function is automatically included when `MICROPY_PY_BUILTINS_HELP` is enabled, which is true for this port. The `builtins.open` function is automatically included when `MICROPY_PY_IO` is enabled, which is true when `MICROPY_VFS` is enabled on this port. If `MICROPY_MBFS` is enabled instead of the VFS then `open` must be explicitly provided. Tested on: - ARDUINO_NANO_33_BLE_SENSE: now has only a single `help` and `open` - MICROBIT: now has only a single `help` and `open` - MICROBIT with MICROPY_MBFS enabled: `help` and `open` both still exist and `open` works with mbfs Signed-off-by: Damien George <damien@micropython.org>

The Pololu Zumo 2040 Robot is supported in pico-sdk now so we should not include the header file here anymore, similarly to other boards. This is necessary for future changes from the SDK to be reflected in MicroPython builds. Signed-off-by: Paul Grayson <paul@pololu.com>
Replace the custom rosc_random_u8()/rosc_random_u32() implementation with the pico_rand API from the Pico SDK. The RP2040 datasheet notes that ROSC "does not meet the requirements of randomness for security systems because it can be compromised", and the current 8-bit LFSR conditioning is not a vetted algorithm under NIST SP 800-90B. pico_rand uses various hardware RNG sources depending on the available platform (including the RP2350 hardware TRNG) and is officially supported and maintained as part of the Pico SDK. This changes os.urandom(), the mbedTLS entropy source, the PRNG seed, and the lwIP random function to all use pico_rand, and removes the custom ROSC random functions from main.c.

When the timeout parameter of `esp32.RMT.wait_done()` is set to a non-zero value, the underlying `rmt_tx_wait_all_done` blocks (it passes the timeout to `xQueueReceive`). Thus we should release the GIL so that other MicroPython threads are not blocked from running. Signed-off-by: Daniël van de Giessen <daniel@dvdgiessen.nl>
This commit lets the native emitter preserve the value of the index register when performing register-indexed loads or stores of halfword or word values on Thumb. The original code was optimised too aggressively for a register-starved architecture like Thumb, and the index value in the sequence to generate was assumed to be allocated somewhere safe. This is valid on other architectures, but not on Thumb. To solve this, load operations do clobber a temporary register that should be safe to use, REG_TEMP2, to store the scaled register offset. REG_TEMP2's value is only used within the scope of a single ASM API instruction. Save operations unfortunately use a register that is aliased to REG_TEMP2, since they need to have three values in registers to perform the operation. This means the index register needs to be pushed to the stack before performing the scale + store operation, and then popped from the stack. That's a 4 bytes penalty on each store and a minor speed hit on generated code (plus a minor footprint increase of the firmware image). Signed-off-by: Alessandro Gatti <a.gatti@frob.it>
This commit lets the native emitter preserve the value of the index register when performing register-indexed loads or stores for halfword or word values on RV32. The original code was optimised too aggressively to reduce the generated code's size, using compressed opcodes that alias the target register to one of the operands. In register-indexed load/store operations, the index register was assumed to be allocated somewhere safe, but it was not always the case. To solve this, now all halfword and word register-indexed operations will use REG_TEMP2 to store the scaled index register. The size penalty on generated code varies across operation sizes and enabled extensions: - byte operations stay the same size with or without Zba - halfword operations will be 2 bytes larger without Zba, and will stay the same size with Zba - word operations will be 4 bytes larger without Zba, and 2 bytes larger with Zba There is also a minor firmware footprint increase to hold the extra logic needed for conditional register clobbering, but it shouldn't be that large anyway.

Call `mp_event_handle_nowait()` in the VFS reader buffer refill path so
that pending scheduled events (USB task, network poll, etc.) get processed
during long-running import/parse/compile operations.
Without this, importing a large Python module from the filesystem blocks
for too long causing TinyUSB event queue to overflow. For example, on
renesas-ra, running a script that imports iperf3 via mpremote run, asserts,
most likely due to SOF interrupts not getting processing:

Factor out mp_os_urandom() of each port into extmod/modos.c, which then calls the port-specific function mp_hal_get_random(). Move mp_hal_get_random() to mphalport where suitable. At the MIMXRT and SAMD it is left in modos.c, since there are different implementation depending on the MCU family. At the ALIF, ESP32, CC3200 and RP2 port the file modos.c was removed, since it was empty after moving mp_hal_get_random(). Tested for the cc3200, esp32, esp8266, mimxrt, nrf, rp2, samd, stm32 and unix ports. Compiled for the alif and the renesas port. Signed-off-by: robert-hh <robert@hammelrath.com>
