Build additional images requested by the product makefile.
This script gives the ability to build multiple additional images and
you can configure what modules/files to include in each image.
1. Define PRODUCT_CUSTOM_IMAGE_MAKEFILES in your product makefile.
PRODUCT_CUSTOM_IMAGE_MAKEFILES is a list of makefiles.
Each makefile configures an image.
For image configuration makefile foo/bar/xyz.mk, the built image
file name
will be xyz.img. So make sure they won't conflict.
2. In each image's configuration makefile, you can define variables:
- CUSTOM_IMAGE_MOUNT_POINT, the mount point, such as "oem", "odm"
etc.
- CUSTOM_IMAGE_PARTITION_SIZE
- CUSTOM_IMAGE_FILE_SYSTEM_TYPE
- CUSTOM_IMAGE_DICT_FILE, a text file defining a dictionary
accepted by BuildImage() in tools/releasetools/build_image.py.
- CUSTOM_IMAGE_MODULES, a list of module names you want to include
in the image; Not only the module itself will be installed to proper
path in the image, you can also piggyback additional files/directories
with the module's LOCAL_PICKUP_FILES.
- CUSTOM_IMAGE_COPY_FILES, a list of "<src>:<dest>" to be copied to
the image. <dest> is relativ to the root of the image.
To build all those images, run "make custom_images".
