The required images must be enumerated in the "loadables" property as a list of strings. +If a platform specific image source file (.its) is shipped with the U-Boot +source, it can be specified using the CONFIG_SPL_FIT_SOURCE Kconfig symbol. +In this case it will be automatically used by U-Boot's Makefile to generate +the image. +If a static source file is not flexible enough, CONFIG_SPL_FIT_GENERATOR +can point to a script which generates this image source file during +the build process. It gets passed a list of device tree files (taken from the +CONFIG_OF_LIST symbol). + The SPL also records to a DT all additional images (called loadables) which are loaded. The information about loadables locations is passed via the DT node with fit-images name. |
