| 17 | # Build additional images requested by the product makefile. |
| 18 | # This script gives the ability to build multiple additional images and you can |
| 19 | # configure what modules/files to include in each image. |
| 20 | # 1. Define PRODUCT_CUSTOM_IMAGE_MAKEFILES in your product makefile. |
| 21 | # PRODUCT_CUSTOM_IMAGE_MAKEFILES is a list of makefiles. |
| 22 | # Each makefile configures an image. |
| 23 | # For image configuration makefile foo/bar/xyz.mk, the built image file name |
| 24 | # will be xyz.img. So make sure they won't conflict. |
| 25 | # 2. In each image's configuration makefile, you can define variables: |
| 26 | # - CUSTOM_IMAGE_MOUNT_POINT, the mount point, such as "oem", "odm" etc. |
| 27 | # - CUSTOM_IMAGE_PARTITION_SIZE |
| 28 | # - CUSTOM_IMAGE_FILE_SYSTEM_TYPE |
| 29 | # - CUSTOM_IMAGE_DICT_FILE, a text file defines a dictionary accepted by |
| 30 | # BuildImage() in tools/releasetools/build_image.py. |
| 31 | # - CUSTOM_IMAGE_MODULES, a list of module names you want to include in |
| 32 | # the image; Not only the module itself will be installed to proper path in |
| 33 | # the image, you can also piggyback additional files/directories with the |
| 34 | # module's LOCAL_PICKUP_FILES. |
| 35 | # - CUSTOM_IMAGE_COPY_FILES, a list of "<src>:<dest>" to be copied to the |
| 36 | # image. <dest> is relativ to the root of the image. |

| 38 | # - CUSTOM_IMAGE_SUPPORT_VERITY, set to "true" if the product supports verity. |
