1451: Work around xtensa deadlock, take 2 r=Dirbaio a=bugadani
This PR is another go at trying to do something with #1449. The commit was part of the previous attempt but mistakenly discarded as I still experienced lockups. However, after further testing, it looks like that lockup is caused by something else.
This is a manual, "cpu-local" critical section impl that should be good enough on dual-core CPUs, although the implementation still contains `SIGNAL_WORK_THREAD_MODE` which is absolutely not correct on dual-core. This approach was chosen because:
- not taking the global lock technically allows the second core to run
- wrapping the signal read and the sleep in a critical section prevents a race condition that would cause the CPU to sleep longer than ideal if an interrupt hits after reading, but before sleeping.

1453: stm32 uart: Fix error flag handling for blocking operations r=Dirbaio a=timokroeger
Clear and report the error flags one by one and pop the data byte only after all error flags were handled.
For v1/v2 we emulate the v3/v4 behaviour by buffering the status register because a read to the data register clears all flags at once which means we might loose all but the first error.
Only tested on stm32f3 discovery board with loopback. Let‘s see what CI says for the other families.
Fixes#1452

1448: rp: don't use SetConfig trait in PWM and PIO. r=Dirbaio a=Dirbaio
It was intended to allow changing baudrate on shared spi/i2c. There's no advantage in using it for PWM or PIO, and makes it less usable because you have to have `embassy-embedded-hal` as a dep to use it.

1424: add TL maibox for stm32wb r=xoviat a=OueslatiGhaith
Hello,
This pull request is related to #1397 and #1401, inspired by #24, build upon the work done in #1405, and was tested on an stm32wb55rg.
This pull request aims to add the transport layer mailbox for stm32wb microcontrollers. For now it's only capable of initializing it and getting the firmware information

1436: rp: Clock configuration r=CBJamo a=CBJamo
Draft of a more complete clock config for the 2040.
I also extended and made public the clk_<name>_freq functions. I know at least the ws2812 pio example would like to get the sys clock at runtime rather than just using a constant. I suspect most pio-based peripherals will want access to the clocks.
Open questions:
1. Best way to handle the 3 external clock frequencies. I think the XIN (aka crystal) freq should just be set by the init function then never changed, though if it's an external clock that could change? I'm not sure anyone would ever want to do that but maybe it should be handled just in case? The other two should probably be set by the application.
2. Better estimation of ROSC frequency. Right now it's really just a lookup table of the speed from the single sample I did this testing on, and only uses the frequency range and div, drive strength is ignored.
3. Probably some kind of warning should be generated if the random bit from the rosc won't be useful, not sure how to do that.
4. Should clocks only be allowed to be configured at init, or should they be modifiable at runtime? For example, switching the RTC to a clock in pin when a pps source is available.
Bonus feature to support clock output. I only implemented the bare minimum, and only for gpout0. I'm sure there's a clean way with macros to impl all 4 without just copy/paste, but I haven't learned macros yet.

we're currently shipping an old boot2 that runs the flash at half speed. use the more recent version instead, and allow user to choose between the different supported boot2 versions for different flash chips if they need that.
