The short version

What changed, and why it matters

This commit tidies up build configuration files for Trezor's Nordic Bluetooth/radio test firmware. It removes some redundant or outdated settings, adds a couple of clarifying options, and disables over-the-air firmware update slots for test builds. There is no direct evidence in the commit that this fixes a security vulnerability; it reads as a routine cleanup of build settings.

Recommended action

No immediate security action required. Treat as routine build cleanup. If reviewing for release, verify that the removed Kconfig options are intentionally obsolete and that the new sysbuild MCUboot settings produce the expected single-slot, no-OTA behavior for test/debug firmware.

Security signals we found

01

Disables secondary firmware update slot for single-app MCUboot builds (SB_CONFIG_MCUBOOT_APP_SYNC_UPDATEABLE_IMAGES=n)

02

Removes deprecated/inconsistent MCUboot single-app Kconfig symbols in favor of sysbuild equivalents

03

Removes CONFIG_BT_TINYCRYPT_ECC from BLE configuration (may rely on alternative ECC implementation)

04

Removes CONFIG_NFCT_PINS_AS_GPIOS (NFC pins no longer repurposed as GPIO in direct test mode)

chore(core): remove sha1 from regular FW

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…

Cryptographic key handling changed: public key is now supplied rather than derivedPotential reduction of key-mismatch risk if caller provides correct public keyNew null-pointer check added for static_public_key

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.
