f302f784e9 stm32/usb: Add config options to disable USB MSC and/or HID.
The new configurations MICROPY_HW_USB_MSC and MICROPY_HW_USB_HID can be
used by a board to enabled or disable MSC and/or HID.  They are both
enabled by default.

fd49fcb229 stm32/gccollect: Always use MP_STATE_THREAD(stack_top) to get stack top.
In a non-thread build, using &_ram_end as the top-of-stack is no longer
correct because the stack is not always at the very top end of RAM.  See
eg 04c7cdb668 and
3786592097.  The correct value to use is
&_estack, which is the value stored in MP_STATE_THREAD(stack_top), and
using the same code for both thread and non-thread builds makes the code
cleaner.

5fd62c8992 stm32: Remove SystemInit funcs, use stm32lib versions instead.
stm32lib now provides system_stm32XXxx.c source files for all MCU variants,
which includes SystemInit and prescaler tables.  Since these are quite
standard and don't need to be changed, switch to use them instead of custom
variants, making the start-up code cleaner.

The SystemInit code in stm32lib was checked and is equivalent to what is
removed from the stm32 port in this commit.

caabdd99c0 stm32/qspi: Handle bus acquisition.
When going out of memory-mapped mode to do a control transfer to the QSPI
flash, the MPU settings must be changed to forbid access to the memory

8da39fd182 stm32/qspi: Use MPU to allow access to valid memory-mapped QSPI region.
The Cortex-M7 CPU will do speculative loads from any memory location that
is not explicitly forbidden.  This includes the QSPI memory-mapped region
starting at 0x90000000 and with size 256MiB.  Speculative loads to this
QSPI region may 1) interfere with the QSPI peripheral registers (eg the
address register) if the QSPI is not in memory-mapped mode; 2) attempt to
access data outside the configured size of the QSPI flash when it is in
memory-mapped mode.  Both of these scenarios will lead to issues with the
QSPI peripheral (eg Cortex bus lock up in scenario 2).

To prevent such speculative loads from interfering with the peripheral the
MPU is configured in this commit to restrict access to the QSPI mapped
region: when not memory mapped the entire region is forbidden; when memory
mapped only accesses to the valid flash size are permitted.

3786592097 stm32/boards: Optimise flash and RAM allocation for L4 boards.
Optimisations are:
- Remove FLASH_ISR section since devices with a small flash sector erase
  size don't need special FLASH_ISR handling.  This reduces flash image by
  approx 1.5k.
- Make SRAM2 contiguous with SRAM1 where possible.
- Simplify configuration of 2k RAM buffer used for flash filesystem.

RAM changes with this commit:
- L432: stack   6k -> 10k,  bss + heap   42k ->  52k
- L476: stack  16k -> 30k,  bss + heap   80k ->  96k
- L496: stack 206k -> 16k,  bss + heap  112k -> 302k

04c7cdb668 stm32: Enter bootloader via a system reset.
Entering a bootloader (ST system bootloader, or custom mboot) from software
by directly branching to it is not reliable, and the reliability of it
working can depend on the peripherals that were enabled by the application
code.  It's also not possible to branch to a bootloader if the WDT is
enabled (unless the bootloader has specific provisions to feed the WDT).

This patch changes the way a bootloader is entered from software by first
doing a complete system reset, then branching to the desired bootloader
early on in the start-up process.  The top two words of RAM (of the stack)
are reserved to store flags indicating that the bootloader should be
entered after a reset.

With this the user can select multiple logical units to expose over USB MSC

feature.  At this point only one LU is used and the behaviour is mostly
unchanged from before, except the INQUIRY result is different (it will
report "Flash" for both flash and SD card).

ce8262a164 stm32/modnetwork: Replace generic netif NIC polling with specific code.
It doesn't work to tie the polling of an underlying NIC driver (eg to check
the NIC for pending Ethernet frames) with its associated lwIP netif.  This
is because most NICs are implemented with IRQs and don't need polling,
because there can be multiple lwIP netif's per NIC driver, and because it
restricts the use of the netif->state variable.  Instead the NIC should
have its own specific way of processing incoming Ethernet frame.

This patch removes this generic NIC polling feature, and for the only
driver that uses it (Wiznet5k) replaces it with an explicit call to the
poll function (which could eventually be improved by using a proper
external interrupt).

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.

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.

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.

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.

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.

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.

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.
