This Patch add functionality for automatic generation of the flash map using DTS description. Automatic generation allows to replace C-hardcoded flash_map. We generate a set of defines based on the index of a partiion: #define DT_FLASH_AREA_<IDX>_OFFSET 0 #define DT_FLASH_AREA_<IDX>_SIZE 131072 #define DT_FLASH_AREA_<IDX>_DEV "FLASH_CTRL" #define DT_FLASH_AREA_<IDX>_LABEL MCUBOOT Additionally we also define: #define DT_FLASH_AREA_NUM 4 and: #define DT_FLASH_AREA_<PARTNAME>_ID 0 Signed-off-by: Findlay Feng <i@fengch.me> Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
