Damien George fae9205594 stm32/boards/LEGO_HUB_NO6: Add support for mboot to access SPI flash.
The following changes are made:
- Use software SPI for external SPI flash access when building mboot.
- Enable the mboot filesystem-loading feature, with FAT FS support.
- Increase the frequency of the CPU when in mboot to 96MHz, to increase the
  speed of SPI flash accesses and programming.

Damien George 6e71cde6aa ports: Use default VFS config for import_stat and builtin_open.
For ports with MICROPY_VFS and MICROPY_PY_IO enabled their configuration
can now be simplified to use the defaults for mp_import_stat and
mp_builtin_open.

This commit makes no functional change, except for the following minor
points:
- the built-in "open" is removed from the minimal port (it previously did
  nothing)
- the duplicate built-in "input" is removed from the esp32 port
- qemu-arm now delegates to VFS import/open

iabdalkader 5562ed3f43 stm32/pyb_can: Replace CAN.initfilterbanks with CAN.init keyword arg.
The CAN.initfilterbanks() class method is removed, and its functionality is
replaced with the "num_filter_banks" keyword argument to the CAN
constructor and CAN.init().  This configures the filter bank split.

This new approach provides more flexibility configuring the resources used
by a given CAN instance, allowing other MCUs like H7 to fit the API.  It
also brings CAN closer to how other machine peripherals are configured,
where everything is done in the constructor/init method.

This is a breaking change to the CAN API.

iabdalkader e7264e9532 stm32/pyb_can: Add support for bus with mixed Classic/FD nodes.

could be configured for either standard or extended ID, but not both/mixed
operation.

This patch allows extended IDs to be filtered and enabled on a per-message
basis, in send(), setfilter() and clearfilter().

This is a breaking change to the API: init() no longer accepts the extframe
keyword argument.

since updating L4 HAL v1.17.0 in a0f5b3148a.

Fixes issue #8233.

Damien George e4f59a0020 stm32/rtc: Use LL_RTC functions to simplify some MCU-specific code.
This also fixes a possible race condition when exiting initialisation mode:
reading then writing to ISR (via ISR &= ~RTC_ISR_INIT) will clear any flags
that were set by the hardware between the read and the write.  The correct
way to clear just the INIT bit is to just do a single write via ISR =
~RTC_ISR_INIT, which will not clear any other flags (they must be written
to 0 to clear), and that is exactly what LL_RTC_DisableInitMode does.

The inclusion of `umachine` in the list of built-in modules is now done
centrally in py/objmodule.c.  Enabling MICROPY_PY_MACHINE will include this
module.

As part of this, all ports now have `umachine` as the core module name
(previously some had only `machine` as the name).

Damien George c8c229b96c stm32/mboot: Use PLL3 for USB clock source on H7 MCUs.
PLL3-Q is more reliable than PLL1-Q for the USB clock source when entering
mboot from various reset states (eg power on vs MCU reset).  (It was found
that if the main application used PLL3-Q then sometimes the USB clock
source would stay stuck on PLL3-Q and not switch to PLL1-Q after a reset.)

Other related changes:
- SystemCoreClockUpdate() should be called on H7 because the calculation
  can be involved in some cases.
- __set_PRIMASK(0) should be called because on H7 the built-in ST DFU
  bootloader exits with IRQs disabled.

Damien George c99ed8d6fa stm32/powerctrl: Write bootloader-state as 64-bit word to work on H7.
H7 MCUs have ECC and writes do not go through to SRAM until 64-bits have
been written (on another location is written).  So use 64-bit writes for
the bootloader-state variable so it is committed before the system reset.

As part of this change, the lower byte of the bootloader address in
BL_STATE must now be the magic number 0x5a5 for the state to be valid
(previously this was 0x000 which is not as robust).

Herwin Grobben 160e4d9a6d stm32/fdcan: Fix FIFO1 usage and handling of error interrupts.
The original code used a independent state with regards to the interrupt.
During heavy bus error conditions the internal state could become
out-of-sync with the interrupts.

Further explanation: during the development of an application using CAN
communication, a interrupt-run-away was found in some situations.  It was
found that the error interrupt triggered (Warning, Passive or Bus-Off, all
triggered it) the run-away.  The only recovery was a reset.

Two problems were found:
- the error interrupt is enabled but not cleared in the interrupt routine;
- an internal variable 'State' that was used to track the message received
  state (empty, new, full, overflow) that was not directly related to
  interrupt that indicated the state.

In this commit these issues are fixed by adding more values for the
interrupt reason (warning, passive, bus off) and clearing the error
interrupts, and making the internal state directly dependent on the
interrupt state for received messages.

Furthermore, introducing the FIFO1 in the CAN receive stage, another issue
existed.  Even if the messages are received into the FIFO1 (by selecting
message filtering for FIFO0 and FIFO1), the interrupt firing was indicating
FIFO0 Rx.  The configuration of the interrupts for this is now also fixed.
The CAN peripheral has 2 interrupt lines going into the NVIC controller.
The assignment of the interrupt reasons to these 2 interrupt lines was
missing.  Now the reception of FIFO1 messages triggers the second interrupt
line.  Other interrupts (Rx FIFO0 and bus error) are assigned to the first
interrupt line.

Tested on a Nucleo-G474, and also checked the HAL function to work with the
H7 family.
