After a transmission, two receive windows Rx1 and Rx2 are opened
for one second each, one right after the other, after a fixed delay
(for example 5s). The Rx window offset is added to the starting date
of each window and the Rx window duration represents the maximum
delay we will wait for an incoming message before declaring that
a timeout occurred.
A value of -500ms for the offset and 800ms for the duration means
that instead of having Rx1 = [5000, 6000[ and Rx2 = [6000, 7000[
we get Rx1 = [4500, 5300[ and Rx2 = [5500, 6300[. We only cover
30% of the expected windows.
The maximum time a SX127x can take before the Rx side is ready is
TS_HOP + TS_RE = 50µs + 2.33ms. Using 3ms for the offset and
1003ms for the duration will give much better time windows:
Rx1 = [4997, 5997[ and Rx2 = [5997, 7000]. Note that the
lorawan-device crate caps Rx1 end date to Rx2 start date.
This change allows a previously failing Murata CMWX1ZZABZ-091
module (STM32L + SX1276) to connect to the TTN LoRa network.
1173: nRF examples crates names r=lulf a=davidedellagiustina
Fixed nRF examples crates' names: they had the same names and they were conflicting during compilation (Cargo warning).

- fix prescaler not divided which incorrectly set prescaler divided by 3
Issue: #1137
Co-authored-by: Christian Enderle <mail@chrenderle.de>
- Rename feature to `embedded-sdmmc`.
- Move embedded-sdmmc fork repo to the embassy-rs org.
- Remove unused features in the fork
- Fix impl in embassy-stm32
- Add to CI so it doesn't break again.
1161: WIP: Smoltcp socket config r=Dirbaio a=Czocher
This PR updates the smoltcp version to the newest master one as well as implements the feature specified in #1154 - to allow the dhcpv4 socket to be configured.
Currently it should be considered a WIP PR - requires testing.
`@Dirbaio` can you have a look and check if this is compatible with what we discussed on the matrix channel?

This fixes a couple of usb otg bugs that surfaced with `usb_ethernet` example from nrf:
- Properly implemented `Endpoint::wait_enabled()`
- Return `EndpointError::Disabled` when neccessary in `Endpoint::write()`

1160: Stop sampling when exiting the Saadc methods r=huntc a=huntc
Prior to this commit, the onDrop function was being dropped immediately and not on exiting the Saadc sampling methods.
A few other places have been corrected also.
Thanks to Peter Hansen for pointing out this issue.

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`.

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.

1149: Add samples for nrf5340 r=lulf a=Tiwalun
Samples for the nrf5340, copied from the existing nrf samples.
Not sure if copying them is the best way of adding support, or using features in the existing samples would be better?
The code is mostly the same, with some different peripherals and pin mappings for the DK.
