This helps when for example boards come with different SDRAM setups. Instead of having a config for each SDRAM setup we only have a single configuration, but generate multiple images from it. The basic idea behind this is using a PBL. As of now the PBL on ARM has a single entrypoint: barebox_arm_entry. With multi image support instead we have many entrypoints in the PBL. The correct one will be chosen by the linker when generating a particular image. The PBLs can also contain a devicetree which is passed to the regular barebox image. This opens up the way to a true multi board barebox. Additionally each PBL/barebox combination can be encapsulated into a SoC specific image so that the different requirements for the boards booting a image can be met. This series adds the make infrastructure and converts a few boards over to use it.
