feat(nordic): add nrf/ble functionality to T3T2

This commit adds Bluetooth Low Energy (BLE) support for the Trezor T3T2 hardware model. It introduces new board configuration files, pin mappings, build scripts, and firmware binaries for the Nordic nRF54LS05A BLE radio used in T3T2. There…

fix(nordic): select correct hash algorithm for fw validation

This commit fixes the firmware build scripts for Trezor's Nordic Bluetooth chip variant so the correct cryptographic hash algorithm (SHA-256) is used when validating firmware images. Previously, the nRF54L-based boards could end up using S…

Firmware image hash algorithm mismatch between bootloader and expected validation chainBuild script incorrectly placed CMake extra arguments before the '--' separator, potentially causing overlays to be ignored or misappliedBoard-specific Kconfig symbol (SB_CONFIG_BOOT_IMG_HASH_ALG_SHA512) only available on newer NCS version, risking build breakage or silent wrong defaults

fix(nordic): update mcuboot - fixes trezor crypto compatibility

This commit simply updates two configuration files to point the Nordic (nRF) hardware build at newer revisions of Trezor's fork of the MCUboot bootloader. The commit message says it 'fixes trezor crypto compatibility' but gives no details,…

refactor(core): make power manager driver selectable

This is a code reorganization in Trezor's firmware that moves the existing power-management implementation from a folder named after the STM32U5 chip to a folder named after the actual power-management chip (Nordic nPM1300). It also makes …

feat(nordic): add support for different NCS sdk versions

This commit updates Trezor's Bluetooth firmware build system so it can compile against two different Nordic SDK versions (an older 2.9 and a newer 3.3). It adds version checks, pins the correct compiler toolchain, and renames a few Bluetoo…
