- unpack-dfu command no longer requies a secret key to be present
- pack-dfu command raises an exception if no secret key is found

Improvements are:
- Default period is 1000ms with callback disabled.
- if period is not specified then it's not updated (previously, if period
was not specified then it was set to -1 and running the timer callback as
fast as possible, making the REPL unresponsive).
- Use uint64_t to compute delta_ms, and raise a ValueError if the period is
too large.
- If callback is not specified then it's not updated.
- Specifying None for the callback will disable the timer.

This supports SDRAM having only 2 internal banks (using BA0 only), and only
11 (A0-A10) bits of address, such as IS42S16100H (512K x 16bit x 2bank).

This function includes the UART prescaler in the calculation (if it has
one, eg on H7 and WB MCUs).

So these alternate functions can be parsed by the build scripts and used in

The STM32WB has a problem when address resolution is enabled: under certain
conditions the MCU can get into a state where it draws an additional 10mA
or so and eventually ends up with a broken BLE RX path in the silicon. A
simple way to reproduce this is to enable address resolution (which is the
default for NimBLE) and start the device advertising. If there is enough
BLE activity in the vicinity then the device will at some point enter the
bad state and, if left long enough, will have permanent BLE RX damage.
STMicroelectronics are aware of this issue. The only known workaround at
this stage is to not enable address resolution, which is implemented by
this commit.
Work done in collaboration with Jim Mussared aka @jimmo.

Prior to this commit, if C2 was busy (eg lots of BLE activity) then it may
not have had time to respond to the notification on the IPCC_CH_MM channel
by the time additional memory was available to put on that buffer. In such
a case C1 would modify the free buffer list while C2 was potentially
accessing it, and this would eventually lead to lost memory buffers (or a
corrupt linked list). If all buffers become lost then ACL packets
(asynchronous events) can no longer be delivered from C2 to C1.
This commit fixes this issue by waiting for C2 to indicate that it has
finished using the free buffer list.

STM32L476RG MCU of NUCLEO_L476RG board has 6 UART/USART units in total
(USART1, USART2, USART3, UART4, UART5 and LPUART1), but only UART2,
connected to REPL, was defined and available in Python code.
Defined are all 5 remaining UART/USART units including LPUART1.

This commit simplifies the customisation of the main MicroPython execution
loop (4 macros are reduced to 2), and allows a board to have full control
over the execution (or not) of boot.py and main.py.
For boards that use the default start-up code, there is no functional
change in this commit.

Support for C++ was added in 97960dc7deb7a0e691fca5944402cd03386b744b but
that commit didn't include the C++ exception handling table in the binary

The GNU Make dir command uses spaces as item separator so it does not
work for e.g building the STM32 port on Cygwin with a default Arm
installation in "c:/program files (x86)/GNU Arm Embedded Toolchain".
Fix by using POSIX dirname on a quoted path instead.

This allows the user to enable wake-up sources using the EWUP bits, on F7
MCUs.
Disabling the wake-up sources while clearing the wake-up flags follows the

state.reset_mode is updated by `MICROPY_BOARD_BEFORE_SOFT_RESET_LOOP` but
not passed to `init_flash_fs`, and so factory reset is not executed on
boards that do not have a bootloader. This bug was introduced by

Fixes #6903.

A corrupt filesystem may lead to a request for a block which is out of

Two of the defaults have also changed in this commit:
- MICROPY_HW_RFCORE_BLE_LSE_SOURCE changed from 1 to 0, which configures
the LsSource to be LSE (needed due to errata 2.2.1).
- MICROPY_HW_RFCORE_BLE_VITERBI_MODE changed from 0 to 1, which enables
Viterbi mode, following all the ST examples.

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.

With mboot encrpytion and fsload enabled, the DEBUG build -O0 compiler
settings result in mboot no longer fitting in the 32k sector. This commit
changes this to -Og which also brings it into line with the regular stm32
build.

MCUs with device-only USB peripherals (eg L0, WB) do not implement (at
least not in the ST HAL) the HAL_PCD_DisconnectCallback event. So if a USB
cable is disconnected the USB driver does not deinitialise itself
(usbd_cdc_deinit is not called) and the CDC driver can stay in the
USBD_CDC_CONNECT_STATE_CONNECTED state. Then if the USB was attached to
the REPL, output can become very slow waiting in usbd_cdc_tx_always for
500ms for each character.
The disconnect event is not implemented on these MCUs but the suspend event
is. And in the situation where the USB cable is disconnected the suspend
event is raised because SOF packets are no longer received.
The issue of very slow output on these MCUs is fixed in this commit (really
worked around) by adding a check in usbd_cdc_tx_always to see if the USB
device state is suspended, and, if so, breaking out of the 500ms wait loop.
This should also help all MCUs for a real USB suspend.
A proper fix for MCUs with device-only USB would be to implement or somehow
synthesise the HAL_PCD_DisconnectCallback event.
See issue #6672.

Don't clear the IPCC channel flag until we've actually handled the incoming
data, or else the wireless firmware may clobber the IPCC buffer if more
