Now that the Makefile can call a generator script to build a more advanced FIT image, let's use this feature to address the needs of Allwinner boards with 64-bit SoCs (A64 and H5). The (DTB stripped) U-Boot binary and the ATF are static, but we allow an arbitrary number of supported device trees to be passed. The script enters both a DT entry in the /images node and the respective subnode in /configurations to support all listed DTBs. The location of the bl31.bin image from the ARM Trusted Firmware build can either by specified via the BL31 environment variable. If this is not set, the script looks for bl31.bin in U-Boot's build directory (which could be a symlink as well).
