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.
Use -misa-spec=2.2 on newer toolchains, which allows passing the same
-march value to both the linker and the compiler even when binutils and
GCC support difference ISA specs.
This is intended for the bootloader module where we don't enter thread
mode, so mutex must never attempt to switch context.
Instead use a simple busy wait that is enough to make the possible mutex
users (e.g. interrupt based SPI) in bootloader mode work.
- move all generated manifests under $(BINDIR)/suit_files (this can be
overwritten.
- rename signed manifests so that they are of the form:
<somename>.<version>.bin, where <somename> is by default riot.suit.
This avoids cluterring BINDIR while as well having a naming scheme that
allows custom names for manifests addresssing different types of
payloads.
- rename riotboot files so that they are of the form: slot<n>.<version>.bin
- move all generated files under $(BINDIR)/riotboot_files (this can be
overwritten.
This adds:
* SUIT_MANIFEST_BASENAME: allow for non slotfiles payloads to have
different names that slotfiles payloads.
* SUIT_MANIFEST_PAYLOADS: firmware payloads to be published with the
manifest.
* SUIT_MANIFEST_SLOTFILES: firmware payloads referenced by the manifest
in the form 'filename:[offset]:[comp_name]' as expected by
gen_manifest.py.
With this the same recipes suit/publish suit/notify can be used with
non slotfiles payloads.
A backward incompatible change in the RISC-V resulting in instructions
previously included by rv32imac to only be available with
rv32imac_zicsr. All RISC-V CPUs supported by RIOT are hence either
considered as rv32imac (from the old ISA spec point of view) or as
rv32imac_zicsr (from the new ISA spec point of view). This adds a
simple test if GCC understands rv32imac_zicsr and uses it then as march,
but uses rv32imac as march if not.
This flag disables all builtin functions provided by the compiler as
well as disabling all optimizations and error checking related to
standard C library functions. If you're using a C library which
conforms to the ANSI C standard, you want to leave these compiler
features enabled.

This adds a xtimer_no_ztimer_default that is currently always
selected in Makefile, but that can be switched off in Kconfig.
Removing its inclusion will allow switching the default xtimer
backend to ztimer, while allowing for an easy way back.
This PR removes the old xtimer based implementation for sema. Since
this implementation used 64bit timeout, backweard compatibility is
kept by having `sema_wait_timed` be implemented by `ztimer64_usec`
which is enabled by selecting `sema_deprecated`
With this 64bit `sema` api is now deprecated.
- Provide a new tool to list and filter TTYs
- Change `Makefile.include` to use `$(RIOTTOOLS)/usb-serial/ttys.py`
instead of `$(Q)$(RIOTTOOLS)/usb-serial/list-ttys.sh` to implement
`make list-ttys`
- Extend `makefiles/tools/serial.inc.mk` to allow using the most recent
port by passing `MOST_RECENT_PORT=1` as environment variable or
parameter to make
