# - If 'build.offset' is provided, either by JSON or by the environment...
# - Set linker flag LD_FLASH_OFFSET and relocate the VTAB based on 'build.offset'.
# - Set linker flag LD_MAX_DATA_SIZE based on 'build.maximum_ram_size'.
# - Define STM32_FLASH_SIZE from 'upload.maximum_size' for use by Flash-based EEPROM emulation.
#
# - For 'board_build.rename' add a post-action to rename the firmware file.
