The short version

What changed, and why it matters

This commit is a large code reorganization of the NFC (Near Field Communication) driver inside Trezor firmware. It moves the ST25R3916 RFAL library from one directory to another and updates build paths and board configuration files accordingly. There is no indication in the commit message or diff that this fixes a security vulnerability; it is described as a refactoring to make it easier to support different STMicroelectronics chips in the future. The change is mostly a directory rename plus path updates, with no functional security fix visible in the diff.

Recommended action

No security action required. Treat as routine refactoring. If reviewing for supply-chain assurance, verify that the moved RFAL files match the expected ST version 4.0.2 and that no unintended modifications were introduced during the directory rename.

This commit removes the SHA-1 hashing function from the regular Trezor firmware. SHA-1 is an old, weak hash algorithm that is no longer considered secure for sensitive uses. The change deletes the code that exposes SHA-1 to apps running on…

refactor(crypto): pass static public key to `noise_xxpsk3_*_init()`

This commit changes how a cryptographic library sets up secure connections. Previously, the code automatically calculated the public key from the private key. Now, the caller must provide the public key directly. This is a code-quality ref…

refactor(crypto): change order of parameters

This commit simply reorders the arguments of an internal function called dh() and updates every place that calls it. The actual math and security behavior are unchanged; it is a code cleanup with no security effect.
