Damien George e1e3704aa1 stm32/modmachine: Create dedicated asm function to branch to bootloader.
Recent gcc versions (at least 9.1) give a warning about using "sp" in the
clobber list.  Such code is removed by this patch.  A dedicated function is
instead used to set SP and branch to the bootloader so the code has full
control over what happens.

Fixes issue #4785.

Damien George 0557f0b74b esp32/network_ppp: Add a timeout for closing PPP connection.
This also fixes deleting the PPP task, since eTaskGetState() never returns
eDeleted.

A limitation with this patch: once the PPP is deactivated (ppp.active(0))
it cannot be used again. A new PPP instance must be created instead.

iabdalkader 1646eff864 stm32/irq: Fix IRQ_ENABLE_STATS stats config to work on all MCUs.
Only the M4 and M7 MCUs have an FPU and FPU_IRQn, and FPU_IRQn is not
always the last entry/IRQ number.

stijn 90fae9172a py/objarray: Add support for memoryview.itemsize attribute.
This allows figuring out the number of bytes in the memoryview object as
len(memview) * memview.itemsize.

The feature is enabled via MICROPY_PY_BUILTINS_MEMORYVIEW_ITEMSIZE and is
disabled by default.

Elad Namdar 3f54462add unix/modusocket: Fix use of setsockopt in usocket.settimeout impl.
The original code called setsockopt(SO_RCVTIMEO/SO_SNDTIMEO) with NULL
timeout structure argument, which is an illegal usage of that function.
The old code also didn't validate the return value of setsockopt, missing
the bug completely.

Damien George b8c74014e4 stm32/usbd_cdc_interface: Don't retransmit chars if USB is reconnected.
Before this change, if the USB was reconnected it was possible that some
characters in the TX buffer were retransmitted because tx_buf_ptr_out and
tx_buf_ptr_out_shadow were reset while tx_buf_ptr_in wasn't.  That
behaviour is fixed here by retaining the TX buffer state across reconnects.

Fixes issue #4761.

Damien George 97753a1bbc stm32: Move factory reset files and code to separate source file.
The new function factory_reset_make_files() populates the given filesystem
with the default factory files.  It is defined with weak linkage so it can
be overridden by a board.

This commit also brings some minor user-facing changes:

- boot.py is now no longer created unconditionally if it doesn't exist, it
  is now only created when the filesystem is formatted and the other files
  are populated (so, before, if the user deleted boot.py it would be
  recreated at next boot; now it won't be).

- pybcdc.inf and README.txt are only created if the board has USB, because
  they only really make sense if the filesystem is exposed via USB.

Damien George 34942d0a72 stm32/machine_uart: Change default UART timeout to 0, for non blocking.
It's more common to need non-blocking behaviour when reading from a UART,
rather than having a large timeout like 1000ms (the original behaviour).
With a large timeout it's 1) likely that the function will read forever if
characters keep trickling it; or 2) the function will unnecessarily wait
when characters come sporadically, eg at a REPL prompt.

Nguyen Hoan Hoang 9a6f6fd68d nrf/boards: Add support for BLYST Nano module based boards.
- IBK-BLYST-NANO: Breakout board
- IDK-BLYST-NANO: DevKit board with builtin IDAP-M CMSIS-DAP Debug JTAG,
  RGB led
- BLUEIO-TAG-EVIM: Sensor tag board (environmental sensor
  (T, H, P, Air quality) + 9 axis motion sensor)

Also, the LED module has been updated to support individual base level
configuration of each LED. If set, this will be used instead of the
common configuration, MICROPY_HW_LED_PULLUP. The new configuration,
MICROPY_HW_LEDX_LEVEL, where X is the LED number can be used to set
the base level of the specific LED.

Chris Mason 2a791170ce stm32/boards: Add NUCLEO_F413ZH board configuration.
The alternate function pin allocations are different to other NUCLEO-144
boards.  This is because the STM32F413 has a very high peripheral count:
10x UART, 5x SPI, 3x I2C, 3x CAN.  The pinout was chosen to expose all
these devices on separate pins except CAN3 which shares a pin with UART1
and SPI1 which shares pins with DAC.

Chris Mason 1b956ec817 stm32: Add support for F413 MCUs.
Includes:
- Support for CAN3.
- Support for UART9 and UART10.
- stm32f413xg.ld and stm32f413xh.ld linker scripts.
- stm32f413_af.csv alternate function mapping.
- startup_stm32f413xx.s because F413 has different interrupt vector table.
- Memory configuration with: 240K filesystem, 240K heap, 16K stack.

Damien George 3fbf32b947 stm32/powerctrl: Support changing frequency when HSI is clock source.
This patch makes pllvalues.py generate two tables: one for when HSI is used
and one for when HSE is used.  The correct table is then selected at
compile time via the existing MICROPY_HW_CLK_USE_HSI.

stijn 34a7d7ebeb unix/gcollect: Make sure stack/regs get captured properly for GC.
When building with link time optimization enabled it is possible both
gc_collect() and gc_collect_regs_and_stack() get inlined into gc_alloc()
which can result in the regs variable being pushed on the stack earlier
than some of the registers. Depending on the calling convention, those
registers might however contain pointers to blocks which have just been
allocated in the caller of gc_alloc(). Then those pointers end up higher on
the stack than regs, aren't marked by gc_collect_root() and hence get
sweeped, even though they're still in use.

As reported in #4652 this happened for in 32-bit msvc release builds:
mp_lexer_new() does two consecutive allocations and the latter triggered a
gc_collect() which would sweep the memory of the first allocation again.

Damien George cbeac903e8 stm32/main: Increase default UART REPL rx buffer from 64 to 260 bytes.
This allows the UART to buffer at least 256 bytes (taking into account the
extra byte needed by the ring buffer, and word alignment).

Krono fbd4e61e57 esp32/machine_wdt: Add timeout arg to select interval, make WDT panic.
The machine.WDT() now accepts the "timeout" keyword argument to select the
WDT interval.  And the WDT is changed to panic mode which means it will
reset the device if the interval expires (instead of just printing an error
message).

Damien George 8031b7a25c stm32/powerctrl: Deselect PLLSAI as 48MHz src before turning off PLLSAI.
On the STM32F722 (at least, but STM32F767 is not affected) the CK48MSEL bit
must be deselected before PLLSAION is turned off, or else the 48MHz
peripherals (RNG, SDMMC, USB) may get stuck without a clock source.

In such "lock up" cases it seems that these peripherals are still being
clocked from the PLLSAI even though the CK48MSEL bit is turned off.  A hard
reset does not get them out of this stuck state.  Enabling the PLLSAI and
then disabling it does get them out.  A test case to see this is:

    import machine, pyb
    for i in range(100):
        machine.freq(122_000000)
        machine.freq(120_000000)
        print(i, [pyb.rng() for _ in range(4)])

On occasion the RNG will just return 0's, but will get fixed again on the
next loop (when PLLSAI is enabled by the change to a SYSCLK of 122MHz).

Fixes issue #4696.

Damien George 0646e607b5 ports: Convert to use pyexec_file_if_exists() to execute boot/main.py.
The stm32 and nrf ports already had the behaviour that they would first
check if the script exists before executing it, and this patch makes all
other ports work the same way.  This helps when developing apps because
it's hard to tell (when unconditionally trying to execute the scripts) if
the resulting OSError at boot up comes from missing boot.py or main.py, or
from some other error.  And it's not really an error if these scripts don't
exist.

Damien George aa7b32c811 stm32/dac: Rework DAC driver to use direct register access.
This patch makes the DAC driver simpler and removes the need for the ST
HAL.  As part of it, new helper functions are added to the DMA driver,
which also use direct register access instead of the ST HAL.

Main changes to the DAC interface are:

- The DAC uPy object is no longer allocated dynamically on the heap,
  rather it's statically allocated and the same object is retrieved for
  subsequent uses of pyb.DAC(<id>).  This allows to access the DAC objects
  without resetting the DAC peripheral.  It also means that the DAC is only
  reset if explicitly passed initialisation parameters, like "bits" or
  "buffering".

- The DAC.noise() and DAC.triangle() methods now output a signal which is
  full scale (previously it was a fraction of the full output voltage).

- The DAC.write_timed() method is fixed so that it continues in the
  background when another peripheral (eg SPI) uses the DMA (previously the
  DAC would stop if another peripheral finished with the DMA and shut the
  DMA peripheral off completely).

Based on the above, the following backwards incompatibilities are
introduced:

- pyb.DAC(id) will now only reset the DAC the first time it is called,
  whereas previously each call to create a DAC object would reset the DAC.
  To get the old behaviour pass the bits parameter like: pyb.DAC(id, bits).

- DAC.noise() and DAC.triangle() are now full scale.  To get previous
  behaviour (to change the amplitude and offset) write to the DAC_CR (MAMP
  bits) and DAC_DHR12Rx registers manually.
