25ae169e6e stm32: Include .ARM section in firmware for C++ exception handling.
Support for C++ was added in 97960dc7de but
that commit didn't include the C++ exception handling table in the binary
firmware image.  This commit fixes that.

9d674cf7ab stm32/uart: Add support for LPUART1 on L0, L4, H7 and WB MCUs.
Add LPUART1 as a standard UART.  No low power features are supported, yet.
LPUART1 is enabled as the next available UART after the standard U(S)ARTs:

    STM32WB:      LPUART1 = UART(2)
    STM32L0:      LPUART1 = UART(6)
    STM32L4:      LPUART1 = UART(6)
    STM32H7:      LPUART1 = UART(9)

On all ports: LPUART1 = machine.UART('LP1')

LPUART1 is enabled by defining MICROPY_HW_LPUART1_TX and
MICROPY_HW_LPUART1_RX in mpconfigboard.h.

0efa0b5437 stm32/mboot: Add ELEM_TYPE_STATUS element so application can get status.
This new element takes the form: (ELEM_TYPE_STATUS, 4, <address>).  If this
element is present in the mboot command then mboot will store to the given
address the result of the filesystem firmware update process.  The address
can for example be an RTC backup register.

cc2a35b7b2 stm32/rtc: Validate the RTC prescaler on boot and change if incorrect.
Devices with RTC backup-batteries have been shown (very rarely) to have
incorrect RTC prescaler values.  Such incorrect values mean the RTC counts
fast or slow, and will be wrong forever if the power/backup-battery is
always present.

This commit detects such a state at start up (hard reset) and corrects it
by reconfiguring the RTC prescaler values.

0118c07916 stm32/machine_adc: Fix ADC auto-calibration to run when ADC not enabled.
Prior to this commit, the ADC calibration code was never executing because
ADVREGEN bit was set making the CR register always non-zero.

This commit changes the logic so that ADC calibration is always run when
the ADC is disabled and an ADC channel is initialised.  It also uses the LL
API functions to do the calibration, to make sure it is done correctly on
each MCU variant.

893f75546c stm32/boards/NUCLEO_WB55/rfcore_firmware.py: Increase GET_STATE timeout.
When installing WS firmware, the very first GET_STATE can take several
seconds to respond (especially with the larger binaries like
BLE_stack_full).

Allows stm.rfcore_sys_hci to take an optional timeout, defaulting to
SYS_ACK_TIMEOUT_MS (which is 250ms).

520bb88d70 stm32/boards/NUCLEO_WB55/rfcore_firmware.py: Fix flash unlock.
The flash can sometimes be in an already-unlocked state, and attempting to
unlock it again will cause an immediate reset.  So make _Flash.unlock()
check FLASH_CR_LOCK to get the current state.

Also fix some magic numbers for FLASH_CR_LOCK AND FLASH_CR_STRT.

The machine.reset() could be removed because it no longer crashes now that
the flash unlock is fixed.

222ec1a4a8 stm32/boards/NUCLEO_WB55: Add standalone WB55 FUS/WS firmware updater.
This commit adds a script that can be run on-device to install FUS and WS
binaries from the filesystem.  Instructions for use are provided in
the rfcore_firmware.py file.

The commit also removes unneeded functionality from the existing rfcore.py
debug script (and renames it rfcore_debug.py).

3e16763201 stm32/rfcore: Fix FUS layout and size of ipcc_device_info_table_t.
The device info table has a different layout when core 2 is in FUS mode.
In particular it's larger than the 32 bytes used when in WS mode and if the
correct amount of space is not allocated then the end of the table may be
overwritten with other data (eg with FUS version 0.5.3).  So update the
structure to fix this.

Also update rfcore.py to disable IRQs (which are enabled by rfcore.c), to
not depend on uctypes, and to not require the asm_thumb emitter.

06659077a8 all: Update Python code to conform to latest black formatting.
Updating to Black v20.8b1 there are two changes that affect the code in
this repository:

- If there is a trailing comma in a list (eg [], () or function call) then
  that list is now written out with one line per element.  So remove such
  trailing commas where the list should stay on one line.

- Spaces at the start of """ doc strings are removed.

67fd58bbd2 stm32/mboot: Add support for littlefs.
Mboot now supports FAT, LFS1 and LFS2 filesystems, to load firmware from.
The filesystem needed by the board must be explicitly enabled by the
configuration variables MBOOT_VFS_FAT, MBOOT_VFS_LFS1 and MBOOT_VFS_LFS2.
Boards that previously used FAT implicitly (with MBOOT_FSLOAD enabled) must
now add the following config to mpconfigboard.h:

    #define MBOOT_VFS_FAT (1)

e3187b052f stm32/boards/PYBD: Change RTC asynch prediv from 1 to 4.
This change has the following effects:
- Reduces the resolution of the RTC sub-second counter from 30.52us to
  122.07us.
- Allows RTC.calibration() to now support positive values (as well as
  negative values).
- Reduces VBAT current consumption in standby mode by a small amount.

For general purpose use 122us resolution of the sub-second counter is
good enough, and the benefits of full range calibration and minor reduction
in VBAT consumption are worth the change.
