Unlike HWSEM, the MHU IRQ can wake up cores from low-power modes, making it
better suited for notifying remote cores. Note that no special function is

The byte order (endianness) seems to be swapped when read in 8D-8D-8D in
XIP mode, for most flashes, with the exception of MX which seems to swap
half-words.
This commit adds a flash setting to allow parts to enable half-word swap
when data is written, to fix this issue. By default, only endianness is
fixed.
Tested with both MX and ISSI parts on AE3, flash test and simple file

The default dummy cycles may not match the actual flash frequency supported
by a certain board. For example, the MX chip uses 20 dummy cycles by
default which supports up to 200MHz DDR, but the maximum frequency
supported by the AE3 board is 50MHz DDR. So the dummy cycles for this
board can be as low as 6. It's important to set the correct dummy cycles,
as it results in doubling the XIP read speed, in the case of the AE3 board.

This commit adds the beginning of a new alif port with support for Alif
Ensemble MCUs. See https://alifsemi.com/
Supported features of this port added by this commit:
- UART REPL.
- TinyUSB support, for REPL and MSC.
- Octal SPI flash support, for filesystem.
- machine.Pin support.
General notes about the port:
- It uses make, similar to other bare-metal ports here.
- The toolchain is the standard arm-none-eabi- toolchain.
- Flashing a board can be done using either the built-in serial bootloader,
or JLink (both supported here).
- There are two required submodules (one for drivers/SDK, one for security
tools), both of which are open source and on GitHub.
- No special hardware or software is needed for development, just a board
connected over USB.
OpenMV have generously sponsored the development of this port.

PSRAM will be used exclusively if MICROPY_GC_SPLIT_HEAP == 0, it will be
added to RAM if MICROPY_GC_SPLIT_HEAP == 1, and the system will fall back
to RAM only if it's not detected.
Due to the size of PSRAM, GC stack was overflowing and causing the GC to
scan through the entire memory pool. This caused noticable slowdowns
during GC. Increase the stack from 256 to 4096 bytes to avoid overflow and
increase the stack entry type size to accomodate 8MB+ PSRAM.

This commit cleans up a couple of RISC-V specific directives in the

The "riscv" component is already included by the ESP-IDF build

there is no need to add it to the required components list.
The architecture flag for mpy-cross is now set for RISC-V targets, as it
was previously set only for Xtensa targets (and it relied on a string

The PYBD boards use an F7xx which has an errata 2.4.3:
Memory-mapped read operations may fail when timeout counter is enabled
This is unfortunate because it means that once QSPI memory-mapped flash is
accessed the QSPI peripheral will leave the CS pin active (low) forever,
which increases power consumption of the SPI flash chip (because it's
active and waiting for commands). The exact amount of power increase
depends on the flash, but the PYBD_SFx increase by about 2.5mA.
Previously this increase in power only happened when QSPI flash was needed,
eg on PYBD_SF2 when mbedtls or nimble libraries were used. On PYBD_SF6
it's actually never used.
But with the introduction of ROMFS which lives in the QSPI flash, the
memory is always access on start up to see if the ROMFS contains a valid
image (it must read the memory to find out). That means these boards
always consume about 2.5mA more after starting up (compared to when ROMFS
is disabled).
The fix in this commit is to explicitly restart the QSPI memory mapped mode
during the start up process. More precisely, the restart is done after
querying the ROMFS and just before trying to execute `boot.py`. That's the
right location to keep power consumption permanently down if the QSPI is
never used (eg ROMFS image doesn't exist).

On stm32, the startup code attempts to mount the configured filesystem. If
there is an existing littlefs filesystem that's suitable corrupted it's
possible for the reported blocksize to be incorrect here:
uint32_t block_size = lfs2_fromle32(superblock->block_size);
This `block_size` (which is read from the filesystem iteself) is used to
create the len argument passed to `pyb_flash_make_new()`. In that function
the len arg is validated to be a mutliple of the underlying hardware block
size, as well as not bigger than the physical flash. Any failure is raised
as a ValueError. This exception is not caught currently in main, it flows
up to the high level assert / startup failure.
As this occurs before `boot.py` is run, the users (potentially frozen)
application code doesn't have any opportunity to detect and handle the
issue.
This commit adds a helper function which attempts to create a block device,
and on error returns `None` instead of raising an exception. Using this in
main means that a potentially corrupt filesystem will simply remain
unmounted, and the application can handle the issue safely.
The fix here also handles the case where the littlefs filesystem is valid
but the autodetection code (which detects the filesystem size) does not
work correctly. In that case it will retry mounting the filesystem using
the whole size of the block device.

The rp2 port has an incomplete mDNS implementation. The code in `main.c`
calls `mdns_resp_init()` which opens the UDP socket for mDNS. However, no
code in the cyw43 driver makes the proper calls to `mdns_resp_add_netif()`
and `mdns_resp_remove_netif()` to send the announce packets. The wiznet5k
driver does make these calls and was used as a model for these changes.
This commit attempts to address this by very small changes to the
`ports/rp2/cyw43_configport.h` file. The change uses new cyw43 driver
hooks to map the driver macros `CYW43_CB_TCPIP_INIT_EXTRA` and
`CYW43_CB_TCPIP_DEINIT_EXTRA` to the appropriate lwIP mDNS calls.

There's a very odd but predictable sequence of events that breaks Wi-Fi
when using both cores:
1) CPU1 calls pendsv_suspend() - for example sleep() causes
a softtimer node to be inserted, which calls pendsv_suspend().
2) CYW43 sends wakeup IRQ. CPU0 GPIO IRQ handler schedules PendSV
and disables the GPIO IRQ on CPU0, to re-enable after
cyw43_poll() runs and completes.
3) CPU0 PendSV_Handler runs, sees pendsv is suspended, exits.
4) CPU1 calls pendsv_resume() and pendsv_resume() sees PendSV
is pending and triggers it on CPU1.
5) CPU1 runs PendSV_Handler, runs cyw43_poll(), and at the end
it re-enables the IRQ *but now on CPU1*.
However CPU1 has GPIO IRQs disabled, so the CYW43 interrupt never runs
again...
The fix in this commit is to always enable/disable the interrupt on CPU0.
This isn't supported by the pico-sdk, but it is supported by the hardware.

stm32's QSPI driver supports memory-mapped mode. The memory-mapped flash
can also be erased/written to. To support both these modes, it switches in
and out of memory-mapped mode during an erase/write.
If the flash is erased/written and then switched back to memory mapped
mode, the cache related to the memory-mapped region that changed must be
invalidated. Otherwise subsequent code may end up reading old data.
That cache invalidation is currently not being done, and this commit fixes
that.
This bug has been around ever since QSPI memory-mapped mode existed, but
it's never really been observed because it's not common to use flash in
memory-mapped mode and also erase/write it. Eg PYBD_SF2 uses the
memory-mapped flash in read-only mode to store additional firmware.
But since the introduction of ROMFS, things changed. The `vfs.rom_ioctl()`
command can erase/write memory-mapped flash.

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)

This commit enables support for DTLS, i.e. TLS over datagram transport
protocols like UDP. While support for DTLS is absent in CPython, it is
worth supporting it in MicroPython because it is the basis of the
ubiquitous CoAP protocol, used in many IoT projects.
To select DTLS, a new set of "protocols" are added to SSLContext:
- ssl.PROTOCOL_DTLS_CLIENT
- ssl.PROTOCOL_DTLS_SERVER
If one of these is set, the library assumes that the underlying socket is a
datagram-like socket (i.e. UDP or similar).
Our own timer callbacks are implemented because the out of the box
implementation relies on `gettimeofday()`.
This new DTLS feature is enabled on all ports that use mbedTLS.
This commit is an update to a previous PR #10062.
Addresses issue #5270 which requested DTLS support.

The `rp2` package use a global dict `_pio_funcs` to populate a namespace
for `@asm_pio` functions to be executed in. That dict is not cleaned up
after use, keeping references to bound methods of a `PIOASMEmit`. By not
setting/clearing all the functions, `asm_pio_encode` unintentionally allows
the use of the old directives (harmless) as well as `jmp` (in general,
produces the wrong output).
Fix that by making sure `_pio_funcs` is returned to its original state
after using it:
- For `@asm_pio` update the target dict from `_pio_funcs` and then set
additional functions as needed, leaving `_pio_funcs` unchanged.
- For `asm_pio_encode`, borrow `_pio_funcs` to use as globals (avoiding a
bunch of memory alloc/free) but delete the instruction entries after use.

Allowing to use e.g. the Adafruit bootloaders with MicroPython. The .uf2
file is created in addition to the .bin and .hex files allowing to use the
latter ones without the bootloader for debugging and testing.
Changes:
- Set the location of the ISR Vector and .text segment to 0x6000C000 and
0x6000C400.
- Reserve an area at the start of ITCM for a copy of the interrupt vector
table and copy the table on reset to this place.
- Extend `machine.bootloader()` by setting the magic number to enable the
bootloader on reset.
- Create a .uf2 file which skips the segments below 0x6000C000.
The bootloader has to be installed as a preparation step using the board
specific methods, but then the firmware's .uf2 file version can be
installed using the bootloader. The bootloader can be invoked with:
- double reset
- calling machine.bootloader()
- Using the touch1200 method
Double reset is hard to achieve on MIMXRT boards, since there is no clean
reset pin. Some MIMXRT boards provide it by switching the power.
Some boards are excluded from the .uf2 build:
- MIMXRT1050_EVK: The uf2 bootloader is built for the QSPI version of the
board. MicroPython supports the Hyperflash version.
- MIMXRT1176_EVK: No support for this board yet, but it should be possible.

This commit fixes compilation for the ESP8266 port when using a local
toolchain on relatively recent Linux systems.
The documentation asks the user to delete the esptool instance that
comes with the toolchain, in favour of using the one provided by the
system. On Linux systems that are at least two years old (looking at
the CI Ubuntu image as an example), the version of esptool installed
with the package manager isn't called `esptool.py` but just `esptool`.
The Makefile didn't take that into account and used `esptool.py` without
checking if such a command exists, making builds fail.
Now preference is given to the `esptool` command, falling back to
`esptool.py` only if the former command does not exist or it is not
available to the current user, to maintain compatibility with old
setups.

On 64-bit systems this should have no effect.
On 32-bit systems it will force 64-bit file sizes and fixes directory
listing on certain 32-bit ports. This option should work on pretty much
all 32-bit systems these days.

When threading is disabled, the pending events handling code would wait
for an incoming interrupt once there's no more work to do. This bit of
code was Xtensa-specific and wouldn't compile on a RISC-V based MCU.
This commit provides the RISC-V equivalent to that part of the code,
allowing to make threadless MicroPython builds on RISC-V based MCUs.

The current documentation for the `machine.RTC` class contains information
about the `RTC.cancel` method for cancelling pending alarms.
However only two ports (cc3200 and mimxrt) implement this functionality
but under a different name: `RTC.alarm_cancel`. The mimxrt port also
implements `RTC.cancel` but it is aliased to `RTC.alarm_cancel` anyway.
To maintain naming consistency, this commit updates the documentation to
officially define `RTC.alarm_cancel` as the method to call to cancel
pending alarms and deprecates mimxrt's `RTC.cancel` implementation.
`RTC.cancel` in the mimxrt port is thus scheduled for removal in
MicroPython v2.

When a wrapped symbol is provided in its own file, it's possible for the
linker to skip that file entirely and not return to it depending on the
order of libraries passed on the linker command line.
This is because these wrapped symbols create linker cycles (libmain_espXX
depends on liblwip but liblwip now also depends on libmain for the wrapped
functions in lwip_patch.c, for example.)
Linker failure for symbols in lwip_patch.c was reproducible if mDNS was
disabled in the board configuration.
This commit adds an explicit undefined symbol for each file, to ensure
the linker will add the wrapped objects on its first pass.

- Previously the call to esp_wifi_set_channel() would be immediately
overridden by calling esp_wifi_config(...) with the previous channel set.
- AP interface doesn't seem to need more than esp_wifi_config(...) to work.
It will automatically configure 40MHz bandwidth and place the secondary
channel using similar logic to what was being explicitly calculated here.
- However, calling esp_wifi_set_channel() on the STA interface is necessary
if using this interface with ESP-NOW (without connecting to an AP). So
the esp_wifi_set_channel() call is kept in for this purpose. Without
this, tests/multi_espnow/70_channel.py fails.

Prior to this commit, 9-bit UART data could be specified in the constructor
and was transmitted, but the 9th bit was set to 0 when sending, and ignored
when receiving. This commit completes 9-bit support in that the 9th bit is
taken from the data.
9-bit data has to be provided with `uart.write()` and and read with
`uart.read()` as two bytes for each transmitted item, low order byte first.
The data length supplied with `uart.write()` and requested by `uart.read()`
has to be even, which is checked. The size of the UART buffers will be
transparently doubled to cater for 9-bit data.

Changes in this commit:
- When setting PWM parameters of a FLEXPWM AB channel twice within a PWM
cycle, the second setting was ignored. Now the second setting persists.
- With `duty_u16(0)` a FLEXPWM X channel was set to high impedance. Now it
is set to low impedance with value 0 for `invert=False`, and 1 for
`invert=True`.
- The align parameter requires a duty rate and frequency to be set. Align
will now be ignored if freq or duty are missing.

This allows the stream to be set to `None`, which essentially stops all PPP
communication without disconnecting the session.
This allows replacing the stream on-the-fly to suspend it, for example to
send AT commands to a modem without completely disconnecting and
re-establishing the PPP connection:
uart = ppp.config('stream')
ppp.config(stream=None)
uart.write(b'+++')
# do some AT commands
uart.write(b'ATO\r\n')
ppp.config(stream=uart)
Any attempted communication by PPP while the stream is not connected will
register as simple packet loss to the LwIP stack because we return 0 for
any write calls, and protocols like TCP will then automatically handle
retrying.
