FIT is the modern u-boot native image format for kernels, device trees, and ramdisks. Enabling FIT only compiles in support for the image format. For these devices, the kernel+dtb and ramdisk are loaded from separate locations in flash and can be any mix of legacy or FIT images. When using FIT images, the dtb is stored as a separate entry that requires CONFIG_OF_LIBFDT to load it into RAM and pass it to the kernel. u-boot enables EFI support by default but it only builds once FIT support is enabled. EFI support adds ~13k to the binary and is currently unused for any Aspeed platforms. Explicitly disable EFI support now that FIT support is enabled. Tested under qemu with both legacy and FIT kernel+dtb images for palmetto and witherspoon.
