# 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 defines 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.
|
|
# - CUSTOM_IMAGE_SELINUX, set to "true" if the image supports selinux.
|
|
# - CUSTOM_IMAGE_SUPPORT_VERITY, set to "true" if the product supports verity.
|
|
# - CUSTOM_IMAGE_VERITY_BLOCK_DEVICE
|
|
#
|
|
# To build all those images, run "make custom_images".
