If Quad SPI modes qout or qio are set by variable FLASH_MODE, esptool.py has to be called with parameter `--flash_mode dio` so that the first stage bootloader is always using Dual SPI mode.
Examples have previously relied on the (really: some) nightly toolchain
to be the default. As that, in practice, is a problematic assumption,
the latest toolchain to use is now determined programmatically, and that
is set explicitly on the examples that use nightly.

Let's consider firmwares as identical if their flash files are matching.
This will have the side effect that hash mismatches for ESP32 due to
different .debug sections in the ELFFILE are prevented, as for ESP32
the BINFILE is used.
This is also a workaround for Rust's [97685], but primarily to enhance
the error message by pointing out that -Zbuild-std is an option, and
generally presenting the error as RIOT usually does.

Module to lock the shell after a given timeout of time x. When the
shell did not receive any input within time x, then the shell is
locked automatically.
When `MOST_RECENT_PORT` is set to `1`, the most recently added USB
serial is selected. This is a crude but surprisingly effective filter.
However, for the CC2560-Launchpad this doesn't work, as it provides
two USB serials. The first USB serial interface is the targeted UART
bridge and the second controls the debugger. Since the second is added
a tiny fraction after the first, this reliably selects the wrong
interface. Allowing the board to filter USB serials first can avoid
this issue.
This is also useful as e.g. an STM Nucleo board can easily be told
apart from an `samr21-xpro` or an nRF52840dk using such filters.
Placing the SUIT key in the RIOT repository folder is dangerous as
a repo checkout is by most people considered a volatile location.
Since all important files are stored in git, deleting the entire folder
or it's contents is not an uncommon cleanup operation.
If the user is at that point unaware that SUIT key material is stored
in that folder, that key will then be lost.
Another workflow may involve multiple checkouts of the RIOT repository
to multiple folders to work on several features at the same time, or for
easy cross-referencing or splitting of off features from an integration
into a feature branch.
In that case each checkout would use it's own incompatible SUIT key.
To avoid all these pitfalls, place the SUIT keys outside the RIOT
repository in the $XDG_DATA_HOME directory.
DEFAULT_MODULEs declared in defaultmodules_regular.inc.mk MAY only be
disabled at APPLICATION level or in BOARD/CPU Makefile.default. These
modules MAY have complex dependencies themselfs.
DEFAULT_MODULEs declared in defaultmodules_no_recursive_deps.inc.mk MAY be disabled
during dependency resolution. The MUST only have dependencies against
modules with no dependencies themselfs, and these dependencies must
be defined in makefiles/defaultmodules._deps.inc.mk
I think the intention was that SUIT_VENDOR_DOMAIN gets set to
$(SUIT_VENDOR) so it can be overwritten by the build system.
However, no such code was in place yet.
Individual files need to be converted to uf2 format, targets
flashing individual slots or the bootloader will work:
- riotboot/flash-slot%
- riotboot/flash-bootloader
'flash' also works by flashing both the bootloader and slot0
independently.
But not targets flashing combined/extended versions since conversion
of the blob is not possible with the uf2conv.py script.
When doing a `make debug` on a board with riotboot bootloader, the original
(non-offset) elf file gets selected.
This causes all ROM addresses to be at the wrong offset, leading to strange
debug behavior.
Set `DEBUG_ELFFILE` to the .elf file that already accounts for the bootloader
offset so the debugger gets the correct addresses.
