It seems sometimes gcc with LTO will generate otherwise valid assembly
listings that cause 'as' to error out when generating DWARF debug info; see
https://sourceware.org/bugzilla/show_bug.cgi?id=29494
Therefore, don't enable -g by default if LTO is on.
Enabling LTO=1 DEBUG=1 is still possible but may result in random errors
at link time due to 'as' (the error in this case is "Error: unaligned
opcodes detected in executable segment", and the only other easy workaround
is CFLAGS+=-fno-jump-tables which may increase code size significantly).

In-the-field use of these FUS/WS firmware update scripts has exposed some
weak points, causing corrupted FUS/WS firmware to be flashed to the unit.
The problems are mostly caused with the ST GUI application, but sometimes
from un-recognised failures during bin file transfer to the WB55 prior to
running the rfcore_firmware.py script. Other failures were caused by
incorrect load addresses being used, again both from user error copying the
address from the HTML release notes to the GUI tool, but also from
similarly not updating the address correctly in rfcore_firmware.py
To guard against these errors and make it easier to prepare different
versions, this commit adds a few features to the rfcore firmware update
tools:
- When creating the bin file, automatically parse the release note in the
folder to get the correct address.
- Add a footer to the bin file containing the name, version, CRC, address
etc.
- Before flashing rfcore, check if the same version is already installed.
- Verify the CRC and obfuscation key before flashing bin.
- Log the name and version of file being flashed.
This adds support for the LEGO Hub No. 7, aka LEGO Technic Small hub, aka
LEGO SPIKE Essential hub. This board is largely similar to Hub No. 6:
- Same MCU (STM32F413 - different packaging with fewer pins).
- Same Bluetooth chip (TI CC2564).
- Same IMU chip.
- Similar external flash chip - 4MiB instead of 32MiB.
- 2 I/O ports instead of 6.
- No display - only status and battery LEDs.
- Different LED driver chip.
- Only 1 button which is also the power button.
- No speaker.

For bare metal ARM & xtensa targets, passing -g will make the ELF file
larger but doesn't change the binary size. However, this means tools like
gdb, addr2line, etc can extract source-level information from the ELF.
Also standardise -ggdb to -g, these produce the exact same ELF file on
arm-none-eabi-gcc and will use DWARF format for all these ports.
Fixes:
- Should read `definitions` rather than `defintions`.
- Should read `resolution` rather than `resoultion`.
- Should read `inefficient` rather than `inefficent`.
- Should read `closed` rather than `closded`.

System config block contains hardware unrelated to USB. So calling

b30c02afa0.
According to ST Errata ES0206 Rev 18, Section 2.2.1, on STM32F427x,
STM32F437x, STM32F429x and STM32F439x.
If the system tick interrupt is enabled during stop mode while certain
bits are set in the DBGMCU_CR, then the system will immediately wake
from stop mode.
Suggested workaround is to disable system tick timer interrupt when
entering stop mode.
According to ST Errate ES0394 Rev 11, Section 2.2.17, on STM32WB55Cx and
STM32WB35Cx.
If the system tick interrupt is enabled during stop 0, stop 1 or stop 2
while certain bits are set in DBGMCU_CR, then system will immediately
wake from stop mode but the system remains in low power state. The CPU
therefore fetches incorrect data from inactive Flash, which can cause a
hard fault.
Suggested workaround is to disable system tick timer interrupt when
entering stop mode.

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.
CAN.recv() now returns a 5-tuple, with the new element in the second
position being a boolean, True if the ID is extended.
This is a breaking change of the API for CAN.recv().
A CAN bus can have mixed classic/FD nodes. Prior to this patch the CAN API
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.
- Enable CAN FD frame support and BRS.
- Optimize the message RAM usage per FDCAN instance.
- Document the usage and different sections of the Message RAM.
In particular, it is called by the constructor if the instance already
exists. So if the previous instance was deinit'd then it will be deinit'd
a second time.

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.

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

H7 MCUs have ECC and writes do not go through to SRAM until 64-bits have

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.
The keyword "af" has been deprecated for some time and "alt" should be used
instead (but "af" still works).
