ada3d5be7c nrf: rename UARTETWISPIn -> SERIALn
The UARTETWISPIn naming is quite horrible. With the nRF53, Nordic realized this
and renamed the interrupts to SERIALn. Let's copy that for our peripheral names, in nrf53 and nrf91.

examples/stm32wb: do not reserve words at start of RAM.
They're used to communicate from the app to ST's OTA bootloader. See AN5247. 

This bootloader is optional, must be flashed by the user, and requires changing the FLASH start address as well, so the current memory regions still require modifications to use it. Therefore there's no point in reserving these words.

Thanks @adamgreig for investigating the purpose.

1219: stm32/sdmmc: Fix SDIOv1 writes r=Dirbaio a=chemicstry

This fixes writes on sdmmc v1 (SDIO). I'm pretty sure I tested writes in #669, but maybe I was just lucky or I just forgot.

There were two problems:
- Writes require DMA FIFO mode, otherwise SDIO FIFO is under/overrun depending on sdio/pclk2 clock ratio.
- Hardware flow control is broken for sdmmc v1 (I checked F1 and F4 erratas). This causes clock glitches above 12 MHz and results in write CRC errors.

272982ee54 examples/stm32wb: fix linker script.
cortex-m-rt 0.7.2 now enforces the stack is 8-byte aligned. Stack is placed
at `ORIGIN(RAM) + LENGTH(RAM)` by default, which wasn't 8-byte-aligned. See https://github.com/rust-embedded/cortex-m/discussions/469

ST trims 8 bytes from start of RAM, and uses the whole 192kb, so let's just
copy that:

1147: Support codesigning in the firmware updater r=lulf a=huntc

This PR provides a method to verify that firmware has been SHA-512 hashed and signed with a private key given its public key. The implementation provides both [`ed25519-dalek`](https://github.com/dalek-cryptography/ed25519-dalek/blob/main/Cargo.toml) and [`salty`](https://github.com/ycrypto/salty) as the signature verifiers. Either of the `ed25519-dalek` and `ed25519-salty` features is required to enable the functionality from `embassy-boot`.

The `verify_and_mark_updated` method is used in place of `mark_updated` when signing is used via its feature. This avoids the accidental omission of validation where it has been declared as required at compile time. It also keeps the parity of calls at the same number to the previous situation.

The PR permits other types of signature verifiers in the future on the proviso that the [Signature trait](https://github.com/RustCrypto/traits/tree/master/signature) is supported.

Finally, I've updated the CI to include testing `embassy-boot`, which it was doing before. In addition, I've included a unit test for verification based on a `ed25519-dalek` documentation example. This tests both the `dalek` and `salty` implementations.

In terms of code size comparisons, `dalek` adds about 68KiB and `salty` adds about 20KiB. I'm using `salty` myself. I've also tested this out by signing my code with the OpenBSD `signify` utility and then verify it during firmware upload using `salty`.

b0529bc943 Support codesigning in the firmware updater
This commit provides a method to verify that firmware has been signed with a private key given its public key. The implementation uses ed25519-dalek as the signature verifier. An "ed25519" feature is required to enable the functionality. When disabled (the default), calling the firmware updater's verify method will return a failure.

1139: Wdt config changes r=lulf a=huntc

Per commits:

* By passing WDT config around we can control it more easily and promote sharing it between files.

* The memory layout of the s140 crept into a number of memory files, which can cause confusion (well, it did for me!).

* Obtaining the current WDT config is useful so that we do not have to duplicate configurations around the place. A constructor method has been introduced that attempts to return the current running WDT config from the WDT peripheral. The bootloader example has also been updated to show how the watchdog can be obtained and used.

1127: clean up doc comment generation r=Dirbaio a=Weshnaw

I noticed that when I created doc comments for my tasks that the doc comments got included on the inner function but not the outer functions, I personally prefer keeping the documentation as clean as possible so this PR aims to hide the inner function and then add doc comments to the outer function.

The actual changes include:
* adding #[doc(hidden)] onto the `task_inner` function
  * I flip flopped on this one because I could imagine someone may want this in their docs, but decided to include but I think arguments could be made either way
* copy the attributes from `task_inner` to `task_outer`
  * I don't work with proc_macros often so I am not entirely sure if the way I went about it is correct but it seems to work fine
    * specifically: using `parse_quote` to create the `task_outer` as a `ItemFn` then duplicating the attributes from `task_inner` to `task_outer`
  * I also am not sure if it's a good idea to duplicate all attributes over, but I honestly wasn't sure how to just get the just doc comment attributes

1049: embassy-nrf: Add I2S module r=lulf a=chris-zen

This PR adds I2S support for the nrf52 series (`nrf52832`, `nrf52833`, `nrf52840`).

We could only test it in a `nrf52840` in master mode for an output stream (see `i2s_waveform` example), using a clone of the [Adafruit I2S Stereo Decoder - UDA1334A](https://learn.adafruit.com/adafruit-i2s-stereo-decoder-uda1334a/overview).

We were wondering if this could be a welcome addition to embassy, as we are working on this very informally and don't have much free time for it.

1024: stm32/adc: Remove voltage and temperature conversions r=Dirbaio a=GrantM11235

The current conversion utilities are confusing and a bit of a footgun. (Two out of the three examples got it wrong! They didn't measure vref at all, so all the conversions are completely wrong if vcca isn't 3.3v)

I think we should eventually have some sort of conversion utilities in the HAL, but for now I think it is best to just remove it and let the users do their own math.

1025: Implement I2C timeouts, second attempt r=Dirbaio a=chemicstry

This is an alterrnative to #1022 as discussed there.

Timeouts are implemented using suggested `check_timeout: impl Fn() -> Result<(), Error>` function, which does not depend on `embassy-time` by default and is a noop for regular I2C.

This also adds `time` feature like in `embassy-nrf` to enable `embassy-time` dependencies. While at it, I also gated some other peripherals that depend on `embassy-time`, notably `usb` and (partially) `subghz`.

`TimeoutI2c` is currently only implemented for i2cv1, because i2cv2 has additional complications:
- Async methods still use a lot of busy waiting code in between DMA transfers, so simple `with_timeout()` will not work and it will have to use both types of timeouts. It could probably be rewritten to replace busy waits with IRQs, but that's outside the scope of this PR.
- I2C definition `I2c<'d, T, TXDMA, RXDMA>` is different from i2cv1 `I2c<'d, T>` making it hard to share single `TimeoutI2c` wrapper. A couple of options here:
  - Duplicate `TimeoutI2c` code
  - Add dummy `TXDMA`, `RXDMA` types to i2cv1 considering that in the future it should also support DMA

984: rp pico async i2c implementation r=Dirbaio a=jsgf

This implements an interrupt-driven async i2c master. It is based on https://github.com/embassy-rs/embassy/pull/914, a bit of https://github.com/embassy-rs/embassy/pull/978 and `@ithinuel's` https://github.com/ithinuel/rp2040-async-i2c.git

This is still work-in-progress, and is currently untested.

1006: Removes some of the code duplication for UarteWithIdle r=Dirbaio a=huntc

This PR removes some of the code duplications for `UarteWithIdle` at the slight expense of requiring a split when using idle processing. As the nRF example illustrates though given the LoC removed, this expense seems worth the benefit in terms of maintenance, and the avoidance of copying over methods. My main motivation for this PR was actually due to the `event_endtx` method not having been copied across to the idle-related code.

Tested the uart_idle example on my nRF52840-dk, and from within my app. Both appear to work fine.

1004: Fix internal channels for adc v2 r=lulf a=chemicstry

Internal channel reading was broken on adc_v2, because `Adc::read()` requires gpio pin trait, which was not implemented by `VrefInt`, `Temperature`, `Vbat`. The required configuration bits `tsvrefe`, `vbate` were not enabled either. This PR makes it a bit closer to how adc_v4 works.

While at it, I also changed adc_v2 to use `RccPeripheral` instead of permanently enabling all ADCs.
