feat(core/build): handle bootloader padding in memusage

This commit changes how a build reporting tool calculates memory usage for the Trezor bootloader. Previously, the tool counted the zero padding that fills the bootloader image up to its maximum size as 'used' memory, making the bootloader …

fix(core/bootloader_ci): fix jumping to fw from CI bootloader

refactor(core): extract pin configuration from NRF driver to board definition

This commit is a straightforward code cleanup: it moves hard-coded pin, clock, and interrupt settings for the Nordic (NRF) radio chip out of the driver code and into board-specific header files. The actual electrical connections and behavi…

fix(core/bootloader): fix codec v1 overflow issues

build(core): use BOOTLOADER_DEVEL flag for keys selection

This commit renames and restructures how Trezor firmware selects cryptographic signing keys for bootloaders. Previously, non-production builds automatically used weaker development/QA keys. Now, a dedicated BOOTLOADER_DEVEL flag controls t…

This commit adds a way to turn off progress animations in the Trezor bootloader. When animations are disabled, the progress value is forced to 0 so the screen does not show a moving progress bar. There is no direct security fix here; it is…
