The short version

What changed, and why it matters

This is a large internal code reorganization in Trezor's embedded firmware. It moves flash/storage headers and build flags around so different firmware images (bootloader, kernel, production test, etc.) declare more explicitly which features they need. There is no obvious security bug introduced, but the change touches low-level memory-layout and storage code, so any mistake could in principle affect how secrets are stored. The commit itself is labeled a refactor and includes no changelog.

Recommended action

Treat as a normal refactor review. Verify that the new feature flags correctly preserve the previous KERNEL_MODE/SECURE_MODE coverage for each firmware target, that the MPU storage-size calculation remains equivalent (NORCOW_SECTOR_COUNT == 2 and STORAGE_AREAS_COUNT was 2), and that removing flash_init() from the Rust storage test does not hide a real initialization requirement. No immediate security response is indicated.

Security signals we found

01

Low-level flash layout and storage initialization code is reorganized

02

KERNEL_MODE / SECURE_MODE compile-time guards are changed to feature flags

03

Storage sector count macro changed from STORAGE_AREAS_COUNT to NORCOW_SECTOR_COUNT in MPU sizing

04

Rust storage test removes explicit flash_init() call

05

No changelog and no explicit security framing by vendor
