- BOARD_PREBUILT_PRODUCTIMAGE
- BOARD_PRODUCTIMAGE_EXTFS_INODE_COUNT
- BOARD_PRODUCTIMAGE_FILE_SYSTEM_TYPE
- BOARD_PRODUCTIMAGE_PARTITION_SIZE
- BOARD_PRODUCTIMAGE_SQUASHFS_BLOCK_SIZE
- BOARD_PRODUCTIMAGE_SQUASHFS_COMPRESSOR
- BOARD_PRODUCTIMAGE_SQUASHFS_COMPRESSOR_OPT
- BOARD_PRODUCTIMAGE_SQUASHFS_DISABLE_4K_ALIGN
- BOARD_USES_PRODUCTIMAGE
- LOCAL_PRODUCT_MODULE
- PRODUCT_FOOTER_ARGS
- PRODUCT_PRODUCT_BASE_FS_PATH
