trezor-firmware/core/SConscript.boardloader
Ondrej Mikle b69ef9d168 feat(core): Copy firmware image header to bootloader RAM to be able to skip directly to firmware install, jumping from firmware to bootloader
Change linking of util.s and limited version of util.s to avoid mistakes
with boardloader etc.
