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

The directory `dist/tools/esptool` already contains a couple of ESP tools and not only esptool.py. As the location for a couple of ESP related tools, it is more clear to call it `esptools` instead of `esptool`.
